+This is the Brotli data compression library from
+https://github.com/google/brotli.
+
+Currently, we import only the Brotli decoder (the /dec/ subdirectory), not the
+encoder (/enc/ subdirectory).
+
+Upstream code can be viewed at
+  https://github.com/google/brotli/tree/master/dec
+
+and cloned by
+  git clone https://github.com/google/brotli
+
+The in-tree copy is updated by running
+  sh update.sh
+from within the modules/brotli directory.
+
+Current version: [commit 29d31d5921b0a2b323ac24e7f7d0cdc9a3c0dd08].

+/* Lookup table to map the previous two bytes to a context id.
+
+   There are four different context modeling modes defined here:
+     CONTEXT_LSB6: context id is the least significant 6 bits of the last byte,
+     CONTEXT_MSB6: context id is the most significant 6 bits of the last byte,
+     CONTEXT_UTF8: second-order context model tuned for UTF8-encoded text,
+     CONTEXT_SIGNED: second-order context model tuned for signed integers.
+
+   The context id for the UTF8 context model is calculated as follows. If p1
+   and p2 are the previous two bytes, we calculate the context as
+
+     context = kContextLookup[p1] | kContextLookup[p2 + 256].
+
+   If the previous two bytes are ASCII characters (i.e. < 128), this will be
+   equivalent to
+
+     context = 4 * context1(p1) + context2(p2),
+
+   where context1 is based on the previous byte in the following way:
+
+     0  : non-ASCII control
+     1  : \t, \n, \r
+     2  : space
+     3  : other punctuation
+     4  : " '
+     5  : %
+     6  : ( < [ {
+     7  : ) > ] }
+     8  : , ; :
+     9  : .
+     10 : =
+     11 : number
+     12 : upper-case vowel
+     13 : upper-case consonant
+     14 : lower-case vowel
+     15 : lower-case consonant
+
+   and context2 is based on the second last byte:
+
+     0 : control, space
+     1 : punctuation
+     2 : upper-case letter, number
+     3 : lower-case letter
+
+   If the last byte is ASCII, and the second last byte is not (in a valid UTF8
+   stream it will be a continuation byte, value between 128 and 191), the
+   context is the same as if the second last byte was an ASCII control or space.
+
+   If the last byte is a UTF8 lead byte (value >= 192), then the next byte will
+   be a continuation byte and the context id is 2 or 3 depending on the LSB of
+   the last byte and to a lesser extent on the second last byte if it is ASCII.
+
+   If the last byte is a UTF8 continuation byte, the second last byte can be:
+     - continuation byte: the next byte is probably ASCII or lead byte (assuming
+       4-byte UTF8 characters are rare) and the context id is 0 or 1.
+     - lead byte (192 - 207): next byte is ASCII or lead byte, context is 0 or 1
+     - lead byte (208 - 255): next byte is continuation byte, context is 2 or 3
+
+   The possible value combinations of the previous two bytes, the range of
+   context ids and the type of the next byte is summarized in the table below:
+

+
+   The context id for the signed context mode is calculated as:
+
+     context = (kContextLookup[512 + p1] << 3) | kContextLookup[512 + p2].
+
+   For any context modeling modes, the context ids can be calculated by |-ing
+   together two lookups from one table using context model dependent offsets:
+
+     context = kContextLookup[offset1 + p1] | kContextLookup[offset2 + p2].
+
+   where offset1 and offset2 are dependent on the context mode.

+ *
+ * Method
+ *   1. Argument reduction:
+ *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
+ *	Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
+ *
+ *      Here r will be represented as r = hi-lo for better 
+ *	accuracy.
+ *
+ *   2. Approximation of exp(r) by a special rational function on
+ *	the interval [0,0.34658]:
+ *	Write
+ *	    R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
+ *      We use a special Remes algorithm on [0,0.34658] to generate 
+ * 	a polynomial of degree 5 to approximate R. The maximum error 
+ *	of this polynomial approximation is bounded by 2**-59. In
+ *	other words,
+ *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
+ *  	(where z=r*r, and the values of P1 to P5 are listed below)
+ *	and
+ *	    |                  5          |     -59
+ *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
+ *	    |                             |
+ *	The computation of exp(r) thus becomes
+ *                             2*r
+ *		exp(r) = 1 + -------
+ *		              R - r
+ *                                 r*R1(r)	
+ *		       = 1 + r + ----------- (for better accuracy)
+ *		                  2 - R1(r)
+ *	where
+ *			         2       4             10
+ *		R1(r) = r - (P1*r  + P2*r  + ... + P5*r   ).
+ *	
+ *   3. Scale back to obtain exp(x):
+ *	From step 1, we have
+ *	   exp(x) = 2^k * exp(r)
+ *
+ * Special cases:
+ *	exp(INF) is INF, exp(NaN) is NaN;
+ *	exp(-INF) is 0, and
+ *	for finite argument, only exp(0)=1 is exact.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).

+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate

+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.

+ *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)

+ *	3. Finally,  log(x) = k*ln2 + log(1+f).

+ *           ------------------------------------------
+ * Method: 
+ *   Bit by bit method using integer arithmetic. (Slow, but portable) 
+ *   1. Normalization
+ *	Scale x to y in [1,4) with even powers of 2: 
+ *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
+ *		sqrt(x) = 2^k * sqrt(y)
+ *   2. Bit by bit computation
+ *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
+ *	     i							 0
+ *                                     i+1         2
+ *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
+ *	     i      i            i                 i
+ *                                                        
+ *	To compute q    from q , one checks whether 
+ *		    i+1       i                       
+ *
+ *			      -(i+1) 2
+ *			(q + 2      ) <= y.			(2)
+ *     			  i
+ *							      -(i+1)
+ *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
+ *		 	       i+1   i             i+1   i
+ *
+ *	With some algebric manipulation, it is not difficult to see
+ *	that (2) is equivalent to 
+ *                             -(i+1)
+ *			s  +  2       <= y			(3)
+ *			 i                i
+ *
+ *	The advantage of (3) is that s  and y  can be computed by 
+ *				      i      i
+ *	the following recurrence formula:
+ *	    if (3) is false
+ *
+ *	    s     =  s  ,	y    = y   ;			(4)
+ *	     i+1      i		 i+1    i
+ *
+ *	    otherwise,
+ *                         -i                     -(i+1)
+ *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
+ *           i+1      i          i+1    i     i
+ *				
+ *	One may easily use induction to prove (4) and (5). 
+ *	Note. Since the left hand side of (3) contain only i+2 bits,
+ *	      it does not necessary to do a full (53-bit) comparison 
+ *	      in (3).
+ *   3. Final rounding
+ *	After generating the 53 bits result, we compute one more bit.
+ *	Together with the remainder, we can decide whether the
+ *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
+ *	(it will never equal to 1/2ulp).
+ *	The rounding mode can be detected by checking whether
+ *	huge + tiny is equal to huge, and whether huge - tiny is
+ *	equal to huge for some floating point number "huge" and "tiny".
+ *		
+ * Special cases:
+ *	sqrt(+-0) = +-0 	... exact
+ *	sqrt(inf) = inf
+ *	sqrt(-ve) = NaN		... with invalid signal
+ *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
+ *

+Other methods  (use floating-point arithmetic)
+-------------
+(This is a copy of a drafted paper by Prof W. Kahan 
+and K.C. Ng, written in May, 1986)
+
+	Two algorithms are given here to implement sqrt(x) 
+	(IEEE double precision arithmetic) in software.
+	Both supply sqrt(x) correctly rounded. The first algorithm (in
+	Section A) uses newton iterations and involves four divisions.
+	The second one uses reciproot iterations to avoid division, but
+	requires more multiplications. Both algorithms need the ability
+	to chop results of arithmetic operations instead of round them, 
+	and the INEXACT flag to indicate when an arithmetic operation
+	is executed exactly with no roundoff error, all part of the 
+	standard (IEEE 754-1985). The ability to perform shift, add,
+	subtract and logical AND operations upon 32-bit words is needed
+	too, though not part of the standard.
+
+A.  sqrt(x) by Newton Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively 
+
+	    1    11		     52				  ...widths
+	   ------------------------------------------------------
+	x: |s|	  e     |	      f				|
+	   ------------------------------------------------------
+	      msb    lsb  msb				      lsb ...order
+
+ 
+	     ------------------------  	     ------------------------
+	x0:  |s|   e    |    f1     |	 x1: |          f2           |
+	     ------------------------  	     ------------------------
+
+	By performing shifts and subtracts on x0 and x1 (both regarded
+	as integers), we obtain an 8-bit approximation of sqrt(x) as
+	follows.
+
+		k  := (x0>>1) + 0x1ff80000;
+		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
+	Here k is a 32-bit integer and T1[] is an integer array containing
+	correction terms. Now magically the floating value of y (y's
+	leading 32-bit word is y0, the value of its trailing word is 0)
+	approximates sqrt(x) to almost 8-bit.
+
+	Value of T1:
+	static int T1[32]= {
+	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
+	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
+	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
+	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
+
+    (2)	Iterative refinement
+
+	Apply Heron's rule three times to y, we have y approximates 
+	sqrt(x) to within 1 ulp (Unit in the Last Place):
+
+		y := (y+x/y)/2		... almost 17 sig. bits
+		y := (y+x/y)/2		... almost 35 sig. bits
+		y := y-(y-x/y)/2	... within 1 ulp
+
+
+	Remark 1.
+	    Another way to improve y to within 1 ulp is:
+
+		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
+		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
+
+				2
+			    (x-y )*y
+		y := y + 2* ----------	...within 1 ulp
+			       2
+			     3y  + x
+
+
+	This formula has one division fewer than the one above; however,
+	it requires more multiplications and additions. Also x must be
+	scaled in advance to avoid spurious overflow in evaluating the
+	expression 3y*y+x. Hence it is not recommended uless division
+	is slow. If division is very slow, then one should use the 
+	reciproot algorithm given in section B.
+
+    (3) Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be 
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+		I := FALSE;	... reset INEXACT flag I
+		R := RZ;	... set rounding mode to round-toward-zero
+		z := x/y;	... chopped quotient, possibly inexact
+		If(not I) then {	... if the quotient is exact
+		    if(z=y) {
+		        I := i;	 ... restore inexact flag
+		        R := r;  ... restore rounded mode
+		        return sqrt(x):=y.
+		    } else {
+			z := z - ulp;	... special rounding
+		    }
+		}
+		i := TRUE;		... sqrt(x) is inexact
+		If (r=RN) then z=z+ulp	... rounded-to-nearest
+		If (r=RP) then {	... round-toward-+inf
+		    y = y+ulp; z=z+ulp;
+		}
+		y := y+z;		... chopped sum
+		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
+	        I := i;	 		... restore inexact flag
+	        R := r;  		... restore rounded mode
+	        return sqrt(x):=y.
+		    
+    (4)	Special cases
+
+	Square root of +inf, +-0, or NaN is itself;
+	Square root of a negative number is NaN with invalid signal.
+
+
+B.  sqrt(x) by Reciproot Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively
+	(see section A). By performing shifs and subtracts on x0 and y0,
+	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
+
+	    k := 0x5fe80000 - (x0>>1);
+	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
+
+	Here k is a 32-bit integer and T2[] is an integer array 
+	containing correction terms. Now magically the floating
+	value of y (y's leading 32-bit word is y0, the value of
+	its trailing word y1 is set to zero) approximates 1/sqrt(x)
+	to almost 7.8-bit.
+
+	Value of T2:
+	static int T2[64]= {
+	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
+	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
+	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
+	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
+	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
+	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
+	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
+	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
+
+    (2)	Iterative refinement
+
+	Apply Reciproot iteration three times to y and multiply the
+	result by x to get an approximation z that matches sqrt(x)
+	to about 1 ulp. To be exact, we will have 
+		-1ulp < sqrt(x)-z<1.0625ulp.
+	
+	... set rounding mode to Round-to-nearest
+	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
+	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
+	... special arrangement for better accuracy
+	   z := x*y			... 29 bits to sqrt(x), with z*y<1
+	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
+
+	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
+	(a) the term z*y in the final iteration is always less than 1; 
+	(b) the error in the final result is biased upward so that
+		-1 ulp < sqrt(x) - z < 1.0625 ulp
+	    instead of |sqrt(x)-z|<1.03125ulp.
+
+    (3)	Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be 
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+	R := RZ;		... set rounding mode to round-toward-zero
+	switch(r) {
+	    case RN:		... round-to-nearest
+	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
+	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
+	       break;
+	    case RZ:case RM:	... round-to-zero or round-to--inf
+	       R:=RP;		... reset rounding mod to round-to-+inf
+	       if(x<z*z ... rounded up) z = z - ulp; else
+	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
+	       break;
+	    case RP:		... round-to-+inf
+	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
+	       if(x>z*z ...chopped) z = z+ulp;
+	       break;
+	}
+
+	Remark 3. The above comparisons can be done in fixed point. For
+	example, to compare x and w=z*z chopped, it suffices to compare
+	x1 and w1 (the trailing parts of x and w), regarding them as
+	two's complement integers.
+
+	...Is z an exact square root?
+	To determine whether z is an exact square root of x, let z1 be the
+	trailing part of z, and also let x0 and x1 be the leading and
+	trailing parts of x.
+
+	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
+	    I := 1;		... Raise Inexact flag: z is not exact
+	else {
+	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
+	    k := z1 >> 26;		... get z's 25-th and 26-th 
+					    fraction bits
+	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
+	}
+	R:= r		... restore rounded mode
+	return sqrt(x):=z.
+
+	If multiplication is cheaper then the foregoing red tape, the 
+	Inexact flag can be evaluated by
+
+	    I := i;
+	    I := (z*z!=x) or I.
+
+	Note that z*z can overwrite I; this value must be sensed if it is 
+	True.
+
+	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
+	zero.
+
+		    --------------------
+		z1: |        f2        | 
+		    --------------------
+		bit 31		   bit 0
+
+	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
+	or even of logb(x) have the following relations:
+
+	-------------------------------------------------
+	bit 27,26 of z1		bit 1,0 of x1	logb(x)

+ *
+ * The following describes the overall strategy for computing

+ * term of the polynomial are done by the caller for increased accuracy
+ * when different bases are used.
+ *
+ * Method :                  
+ *   1. Argument Reduction: find k and f such that 
+ *			x = 2^k * (1+f), 
+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *   2. Approximation of log(1+f).
+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate 
+ * 	a polynomial of degree 14 to approximate R The maximum error 
+ *	of this polynomial approximation is bounded by 2**-58.45. In
+ *	other words,
+ *		        2      4      6      8      10      12      14
+ *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
+ *  	(the values of Lg1 to Lg7 are listed in the program)
+ *	and
+ *	    |      2          14          |     -58.45
+ *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2 
+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log
+ *	by
+ *		log(1+f) = f - s*(f - R)	(if f is not too large)
+ *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
+ *	
+ *	3. Finally,  log(x) = k*ln2 + log(1+f).  
+ *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ *	   Here ln2 is split into two floating point number: 
+ *			ln2_hi + ln2_lo,
+ *	   where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ *	log(x) is NaN with signal if x < 0 (including -INF) ; 
+ *	log(+INF) is +INF; log(0) is -INF with signal;
+ *	log(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following 
+ * constants. The decimal values may be used, provided that the 
+ * compiler will convert from decimal to binary accurately enough

+ * exponent overflow or underflow must not occur.  This uses a Theorem of
+ * Dekker (1971).  See Knuth (1981) 4.2.2 Theorem C.  The name "TwoSum"

+ *
+ * For this to always work, assignment of a + b to 'a' must not retain any
+ * extra precision in a + b.  This is required by C standards but broken
+ * in many compilers.  The brokenness cannot be worked around using
+ * STRICT_ASSIGN() like we do elsewhere, since the efficiency of this
+ * algorithm would be destroyed by non-null strict assignments.  (The
+ * compilers are correct to be broken -- the efficiency of all floating
+ * point code calculations would be destroyed similarly if they forced the
+ * conversions.)
+ *
+ * Fortunately, a case that works well can usually be arranged by building
+ * any extra precision into the type of 'a' -- 'a' should have type float_t,
+ * double_t or long double.  b's type should be no larger than 'a's type.
+ * Callers should use these types with scopes as large as possible, to
+ * reduce their own extra-precision and efficiciency problems.  In
+ * particular, they shouldn't convert back and forth just to call here.

+/* expm1(x)
+ * Returns exp(x)-1, the exponential of x minus 1.
+ *
+ * Method
+ *   1. Argument reduction:
+ *	Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
+ *
+ *      Here a correction term c will be computed to compensate
+ *	the error in r when rounded to a floating-point number.
+ *
+ *   2. Approximating expm1(r) by a special rational function on
+ *	the interval [0,0.34658]:
+ *	Since
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
+ *	we define R1(r*r) by
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
+ *	That is,
+ *	    R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
+ *		     = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
+ *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
+ *      We use a special Reme algorithm on [0,0.347] to generate
+ * 	a polynomial of degree 5 in r*r to approximate R1. The
+ *	maximum error of this polynomial approximation is bounded
+ *	by 2**-61. In other words,
+ *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
+ *	where 	Q1  =  -1.6666666666666567384E-2,
+ * 		Q2  =   3.9682539681370365873E-4,
+ * 		Q3  =  -9.9206344733435987357E-6,
+ * 		Q4  =   2.5051361420808517002E-7,
+ * 		Q5  =  -6.2843505682382617102E-9;
+ *		z   =  r*r,
+ *	with error bounded by
+ *	    |                  5           |     -61
+ *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
+ *	    |                              |
+ *
+ *	expm1(r) = exp(r)-1 is then computed by the following
+ * 	specific way which minimize the accumulation rounding error:
+ *			       2     3
+ *			      r     r    [ 3 - (R1 + R1*r/2)  ]
+ *	      expm1(r) = r + --- + --- * [--------------------]
+ *		              2     2    [ 6 - r*(3 - R1*r/2) ]
+ *
+ *	To compensate the error in the argument reduction, we use
+ *		expm1(r+c) = expm1(r) + c + expm1(r)*c
+ *			   ~ expm1(r) + c + r*c
+ *	Thus c+r*c will be added in as the correction terms for
+ *	expm1(r+c). Now rearrange the term to avoid optimization
+ * 	screw up:
+ *		        (      2                                    2 )
+ *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
+ *	 expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
+ *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
+ *                      (                                             )
+ *
+ *		   = r - E
+ *   3. Scale back to obtain expm1(x):
+ *	From step 1, we have
+ *	   expm1(x) = either 2^k*[expm1(r)+1] - 1
+ *		    = or     2^k*[expm1(r) + (1-2^-k)]
+ *   4. Implementation notes:
+ *	(A). To save one multiplication, we scale the coefficient Qi
+ *	     to Qi*2^i, and replace z by (x^2)/2.
+ *	(B). To achieve maximum accuracy, we compute expm1(x) by
+ *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
+ *	  (ii)  if k=0, return r-E
+ *	  (iii) if k=-1, return 0.5*(r-E)-0.5
+ *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
+ *	       	       else	     return  1.0+2.0*(r-E);
+ *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
+ *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
+ *	  (vii) return 2^k(1-((E+2^-k)-r))
+ *
+ * Special cases:
+ *	expm1(INF) is INF, expm1(NaN) is NaN;
+ *	expm1(-INF) is -1, and
+ *	for finite argument, only expm1(0)=0 is exact.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Misc. info.
+ *	For IEEE double
+ *	    if x >  7.09782712893383973096e+02 then expm1(x) overflow
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.

+ *      Note. If k=0, then f=x is exact. However, if k!=0, then f
+ *	may not be representable exactly. In that case, a correction
+ *	term is need. Let u=1+x rounded. Let c = (1+x)-u, then
+ *	log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
+ *	and add back the correction term c/u.
+ *	(Note: when x > 2**53, one can simply return log(x))
+ *
+ *   2. Approximation of log1p(f).
+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate
+ * 	a polynomial of degree 14 to approximate R The maximum error
+ *	of this polynomial approximation is bounded by 2**-58.45. In
+ *	other words,
+ *		        2      4      6      8      10      12      14
+ *	    R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s  +Lp6*s  +Lp7*s
+ *  	(the values of Lp1 to Lp7 are listed in the program)
+ *	and
+ *	    |      2          14          |     -58.45
+ *	    | Lp1*s +...+Lp7*s    -  R(z) | <= 2
+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log
+ *	by
+ *		log1p(f) = f - (hfsq - s*(hfsq+R)).
+ *
+ *	3. Finally, log1p(x) = k*ln2 + log1p(f).
+ *		 	     = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ *	   Here ln2 is split into two floating point number:
+ *			ln2_hi + ln2_lo,
+ *	   where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ *	log1p(x) is NaN with signal if x < -1 (including -INF) ;
+ *	log1p(+INF) is +INF; log1p(-1) is -INF with signal;
+ *	log1p(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.
+ *
+ * Note: Assuming log() return accurate answer, the following
+ * 	 algorithm can be used to compute log1p(x) to within a few ULP:
+ *
+ *		u = 1+x;
+ *		if(u==1.0) return x ; else
+ *			   return log(u)*(x/(u-1.0));

+# As a preliminary, create a compilation directory and change into it, for
+# example
+#
+#   mkdir ~/freetype2.compiled
+#   cd ~/freetype2.compiled
+#
+# Now you can say
+#
+#   cmake <path-to-freetype2-src-dir>
+#
+# to create a Makefile that builds a static version of the library.
+#
+# For a dynamic library, use
+#
+#   cmake <path-to-freetype2-src-dir> -D BUILD_SHARED_LIBS:BOOL=true
+#
+# For a framework on OS X, use
+#
+#   cmake <path-to-freetype2-src-dir> -D BUILD_FRAMEWORK:BOOL=true -G Xcode
+#
+# instead.
+#
+# For an iOS static library, use
+#
+#   cmake -D IOS_PLATFORM=OS -G Xcode <path-to-freetype2-src-dir>
+#
+# or
+#
+#   cmake -D IOS_PLATFORM=SIMULATOR -G Xcode <path-to-freetype2-src-dir>
+#
+# Please refer to the cmake manual for further options, in particular, how
+# to modify compilation and linking parameters.
+#
+# Some notes.
+#
+# . `cmake' creates configuration files in
+#
+#     <build-directory>/include/freetype/config
+#
+#   which should be further modified if necessary.
+#
+# . You can use `cmake' directly on a freshly cloned FreeType git
+#   repository.
+#
+# . `CMakeLists.txt' is provided as-is since it is normally not used by the
+#   developer team.
+#
+# . If you want to disable the automatic generation of the distribution
+#   targets, add the `-D FREETYPE_NO_DIST=true' command line argument.
+#
+# . Set the `WITH_ZLIB', `WITH_BZip2', `WITH_PNG', and `WITH_HarfBuzz'
+#   CMake variables to `ON' or `OFF' to force or skip using a dependency.
+#   Leave a variable undefined (which is the default) to use the dependency
+#   only if it is available.  Example:
+#
+#     cmake ... -DWITH_ZLIB=ON -DWITH_HarfBuzz=OFF ...
+#
+# . Installation of FreeType can be controlled with the CMake variables
+#   `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'
+#   (this is compatible with the same CMake variables in zlib's CMake
+#   support).

+	strikes, and FreeType doesn't check the validity of all bitmap
+	strikes in advance.
+
+	Reported as
+
+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353
+
+	* src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'.

+
+	This trivial fix allows us to accept more fonts.
+
+	Problem reported by 張俊� <418092625@qq.com>.

+	    Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix linear metrics of GX variation fonts (#49829).
+
+	When asking for an unhinted non-default variations,
+	`linearVertAdvance' is currently the value from the `hmtx' table

+
+	* src/base/ftobjs.c (FT_Open_Face): Code moved to...
+	(ft_open_face_internal): ... this function.

+	field.
+

+
+	The font variation code.  All parts dependent on the GX code in the

+	(CFF_Font): Add `vstore' field.
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar',
+	since glyph variation data is directly embedded.
+	(TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts.
+
+2016-12-15  Dave Arnold  <darnold@adobe.com>
+	    Werner Lemberg  <wl@gnu.org>
+
+	[cff] Implement CFF2 support (1/2).
+
+	This commit does not contain the blend code for font variation

+	[gzip] Improve building with external zlib (#49673).
+
+	Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
+	the following error.
+
+	  ftgzip.c
+	  zlib-1.2.8\zlib.h(86): error C2061:
+	                         syntax error: identifier 'z_const'

+	                          error count exceeds 100; stopping compilation
+
+	The error happens because FreeType keeps an own copy of zlib-1.1.4
+	under `src/gzip'.  When building `src/gzip/ftgzip.c' with
+	FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
+
+	  #include <zlib.h>
+
+	which correctly finds an external `zlib.h', but `zlib.h' itself has
+	a line
+
+	  #include "zconf.h"
+
+	which makes Visual Studio 2015 find `src/gzip/zconf.h' while
+	compiling the files in `src/gzip'.
+
+	* src/gzip/zconf.h: Rename to...
+	* src/gzip/ftzconf.h: ... this.

+
+	[pcf] Enrich family name with foundry name and glyph width info.
+
+	This is a very old patch from openSuSE (from 2006, submitted to
+	FreeType in 2011) that I forgot to apply.
+
+	  https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
+
+	Prepend the foundry name plus a space to the family name.  There are
+	many fonts just called `Fixed' which look completely different, and
+	which have nothing to do with each other.  When selecting `Fixed' in
+	KDE or Gnome one gets results that appear rather random, the style
+	changes often if one changes the size and one cannot select some
+	fonts at all.
+
+	We also check whether we have `wide' characters; all put together,
+	we get family names like `Sony Fixed' or `Misc Fixed Wide'.
+
+	* src/pcf/pcfread.c (pcf_load_font): Implement it.
+
+	* docs/CHANGES: Document it.

+
+	Without this patch, a loca sequence like `0 100000 0 100000 ...',
+	where value 100000 is larger than the `glyf' table size, makes
+	FreeType handle the whole `glyf' table as a single glyph again and

+
+	[smooth] Simplify span rendering more.
+
+	It turns out that there is significant cost associated with `FT_Span'

+
+2016-08-11  Alexei Podtelezhnikov  <apodtele@gmail.com>
+

+
+	[sfnt] Use correct type for `italicAngle' field (#48732).
+
+	* src/sfnt/ttload.c (tt_face_load_post): Fix types.
+
+2016-08-06  Jon Spencer  <jon@jonspencer.ca>
+
+	[sfnt] Fix `FT_Get_Advance' for bitmap strikes.
+
+	`FT_Get_Advance' returns 0 for bitmap fonts.  It first gets the
+	advance value from the font table and then scales it by the
+	`font->size->metrics->x_scale' field.  But `FT_Select_Size' doesn't
+	set that value for bitmap fonts and the advance gets scaled to zero.
+
+	Taken from
+
+	  https://github.com/behdad/harfbuzz/issues/252
+
+	* src/sfnt/ttsbit.c (tt_face_load_strike_metrics)
+	<TT_SBIT_TABLE_TYPE_EBLC>: Set scale values.
+
+2016-08-06  Behdad Esfahbod  <behdad@behdad.org>
+

+
+	* src/truetype/ttgload.c (load_truetype_glyph)
+	[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check `ARGS_ARE_XY_VALUES' flag.
+
+2016-08-05  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Minor refactoring.
+
+	* src/smooth/ftgrays.c (gray_render_scanline, gray_render_line):
+	Updated.
+
+2016-07-29  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
+
+	Since 2016-05-16 we detect infinite recursion directly.
+
+	* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
+	`maxComponentDepth'.
+	* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
+	`maxComponentDepth' is not valid.  Instead, simply adjust its value
+	and emit a tracing message.
+
+2016-07-26  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/aflatin.c (af_latin_metrics_scale_dim): Minor.
+
+	No functional change.
+
+2016-07-22  Hin-Tak Leung  <htl10@users.sourceforge.net>
+
+	[truetype] Record the end of IDEFs.
+
+	To match the logic in FDEF.  The value of the end is only used for
+	bound-checking in `Ins_JMPR', so it may not have been obvious that
+	it was not recorded.  Tested (as part of Font Validator 2.0) all the
+	fonts on Fedora and did not see any change.
+
+	* src/truetype/ttinterp.c (Ins_IDEF): Updated.
+
+2016-07-19  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Sanitizer fix, second try.
+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
+	tests and use only one slot more.
+
+2016-07-19  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Sanitizer fix.
+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array
+	to fix nested loops.
+
+2016-07-18  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Make GETDATA work only for GX fonts.
+
+	* src/truetype/ttinterp.c (opcode_name): Updated.
+	(Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'.
+	(TT_RunIns): Updated.
+
+2016-07-17  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Add support for Apple's
+
+	  GETDATA[], opcode 0x92
+
+	bytecode instruction.  It always returns 17, and we have absolutely
+	no idea what it is good for...
+
+	* src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
+	(Ins_GETDATA): New function.
+	(TT_RunIns): Add it.
+
+2016-07-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Add bytecode support for GX variation fonts.
+
+	This commit implements undocumented (but confirmed) stuff from
+	Apple's old bytecode engine.
+
+	  GETVARIATION[], opcode 0x91
+	    This opcode pushes normalized variation coordinates for all axes
+	    onto the stack (in 2.14 format).  Coordinate of first axis gets
+	    pushed first.
+
+	  GETINFO[], selector bit 3
+	    If GX variation support is enabled, bit 10 of the result is set
+	    to 1.
+
+	* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
+	(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
+	(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
+	bit 3, checking support for variation glyph hinting.
+	(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
+	to implement opcode 0x91.
+	(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
+
+2016-07-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix GETINFO bytecode instruction.
+
+	* src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for
+	stretching information.
+
+2016-07-16  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Make all glyphs in `Zycon' GX font work.
+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary
+	tests.
+
+2016-07-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix GX delta tracing.
+
+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace
+	relative point movements.
+
+2016-07-16  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] More fixes for GX.
+
+	This finally fixes the rendering of the cyclist and the lizard in
+	the `Zycon' font.
+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
+	index is always cumulative.
+
+	(tt_handle_deltas): Rename to...
+	(tt_interpolate_deltas): ... This.
+	Add new parameter for output point array.
+	Update caller.
+
+	(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
+	the intermediate results of `tt_interpolate_deltas' that are to be
+	added to `outline->points'.
+
+2016-07-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
+
+	`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.
+
+	Reported by Alexei.
+
+2016-07-16  Nikolaus Waxweiler  <madigens@gmail.com>
+
+	* src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error.
+
+	Problem reported by Hin-Tak Leung.
+
+2016-07-15  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Update and improve segment and edge tracing.
+
+	* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
+	`delta' also.
+	Don't show first point of segment as a replacement for `pos'; this
+	is (a) misleading, since the difference to `pos' can be almost
+	arbitrarily large in corner cases, and (b) it is better to have all
+	segment data in font units instead of a single value given in output
+	space coordinates.
+	Improve layout.
+	(af_glyph_hints_dump_edges): Show px->units and units->px conversion
+	values for convenience.
+	Improve layout.
+
+2016-07-15  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] For edges, reject segments wider than 1px (#41334).
+
+	* src/autofit/afhints.h (AF_SegmentRec): New member `delta'.
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Compute
+	`delta'.
+	(af_latin_hints_compute_edges): Reject segments with a delta larger
+	than 0.5px.
+
+2016-07-14  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/freetype.h (FT_IS_NAMED_INSTANCE): New macro.
+
+2016-07-14  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt] Fix `face_index' value in `FT_Face' for named instances.
+
+	* src/sfnt/sfobjc.s (sfnt_init_face): Don't strip off higher 16bits.
+
+2016-07-14  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
+
+2016-07-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Fix gxvar delta interpolation.
+
+	The coordinates of the base font should be used for interpolation
+	purposes, NOT the current points (i.e., the result of accumulation
+	of previous deltas).
+
+	* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
+	`points_org' before looping over all tuples.

+	Windows, where the filesystem doesn't preserve case.
+
+2002-01-29  David Turner  <david@freetype.org>
+
+	* configure: Fixed the script.  It previously didn't accept more
+	than one argument correctly.  For example, when typing:
+
+	  ./configure --disable-shared --disable-nls
+
+	the `--disable-nls' was incorrectly sent to the `make' program.
+
+2002-01-29  Werner Lemberg  <wl@gnu.org>

+	src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,
+	src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler
+	warnings (in pedantic compilation modes).
+
+2002-01-05  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation
+	of auto-hinted stem widths; this avoids color fringes in
+	`ClearType-like' rendering.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph_Header,
+	TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):
+	Modified the TrueType loader to make it more paranoid; this avoids
+	nasty buffer overflows in the case of invalid glyph data (as
+	encountered in the output of some buggy font converters).
+
+2002-01-04  David Turner  <david@freetype.org>
+
+	* README.UNX: Added special README file for Unix users.
+
+	* builds/unix/ftsystem.c (FT_New_Stream): Fixed typo.
+
+	* src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid
+	of compiler warnings.
+
+	* src/base/ftoutln.c (FT_Outline_Check): Remove compiler warning.
+
+2002-01-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler
+	warning.
+
+2002-01-03  Keith Packard  <keithp@keithp.com>
+
+	* builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that
+	all FreeType input streams are closed in child processes of a `fork'
+	on Unix systems.  This is important to avoid (potential) access
+	control issues.
+
+2002-01-03  David Turner  <david@freetype.org>
+
+	* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the
+	library when dealing with certain weird fonts like `Stalingrad', in
+	`sadn.pfb' (this font has no full font name entry).
+
+	* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
+	New function to check the consistency of outline data.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
+	ensure that loaded glyphs are valid.  This allows certain fonts like
+	`tt1095m_.ttf' to be loaded even though it appears they contain
+	really funky glyphs.
+
+	There still is a bug there, though.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
+
+2001-12-30  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_hinter_load): Fix advance width
+	computation of auto-hinted glyphs.  This noticeably improves the
+	spacing of letters in KDE and Gnome.
+
+2001-12-25  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* builds/dos/detect.mk: Correcting the order for Borland compilers:
+	16-bit bcc was never selected, always overridden by 32-bit bcc32.
+
+2001-12-22  Francesco Zappa Nardelli  <Francesco.Zappa.Nardelli@ens.fr>
+
+	* src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'
+	and fix incorrect computation of `available_sizes'.
+
+2001-12-22  David Turner  <david@freetype.org>
+
+	* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
+	incorrect glyph advance in the case of mono-width fonts (like
+	Courier, Andale Mono, and others).
+
+2001-12-22  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* builds/amiga/*: Adaptations to latest changes.
+	Support added for MorphOS.
+
+2001-12-22  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.
+	(ps_mask_table_merge, ps_hints_open, ps_hints_stem,
+	ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix
+	FT_ERROR messages.
+	* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as
+	`trace_pshalgo1'.
+	* src/pshinter/pshalgo2.c (FT_COMPONENT): Define as
+	`trace_pshalgo2'.
+	* include/freetype/internal/ftdebug.h (FT_Trace): Updated.
+
+	* docs/modules.txt: New file.
+
+2001-12-21  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):
+	Ignore invalid `hintmask' and `cntrmask' operators (instead of
+	returning an error).  Glyph 2028 of the CFF font `MSung-Light-Acro'
+	couldn't be rendered otherwise (it seems its charstring is buggy,
+	though this requires more analysis).
+	(FT_COMPONENT): Define.
+
+	* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c
+	(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a
+	bug where the X and Y axis where inverted in the postscript hinter.
+	This caused problem when displaying on non-square surfaces.
+
+	* src/pshinter/pshalgo2.c: s/vertical/dimension/.
+
+	* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
+	point constant with a fixed-float equivalent.  For some reasons not
+	all compilers are capable of directly computing a floating pointer
+	constant casted to FT_Fixed, and will link a math library instead.
+
+2001-12-20  Werner Lemberg  <wl@gnu.org>
+
+	* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix
+	tracing strings.

+
+	* src/pshinter/pshrec.c (t2_hint_stems): Fixed.
+
+	* src/base/ftobjs.c (FT_Done_Library): Fixed a stupid bug that
+	crashed the library on exit.
+
+	* src/type1/t1gload.c (T1_Load_Glyph): Enable font matrix
+	transformation of hinted glyphs.
+
+	* src/cid/cidload.c (cid_read_subrs): Fix error condition.
+
+	* src/cid/cidobjs.c (CID_Face_Done): Fixed a memory leak; the subrs
+	routines were never released when CID faces were destroyed.
+
+	* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated
+	to move the definition of encoding tables back within `cffload.c'
+	instead of making them part of a shared header (causing problems in
+	`multi' builds).  This reverts change 2001-08-08.
+
+	* docs/CHANGES: Updated for 2.0.6 release.
+	* docs/TODO: Added `stem3 and counter hints support' to the TODO
+	list for the Postscript hinter.
+	* docs/BUGS: Closed the AUTOHINT-NO-SBITS bug.
+
+2001-12-19  David Turner  <david@freetype.org>
+
+	* include/freetype/cache/ftcache.h: Added comments to indicate that
+	some of the exported functions should only be used by applications
+	that need to implement custom cache types.
+
+	* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug
+	that prevented composites from loading correctly, due to missing

+
+	* src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name'
+	tables optional to load PCL fonts properly.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c
+	(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):
+	`Fixed' the bug that prevented embedded bitmaps to be loaded when
+	the auto-hinter is used.  This actually is a hack but will be enough
+	until the internal re-design scheduled for FreeType 2.1.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline
+	shifting bug in the monochrome renderer.
+
+	* README: Updated version numbers to 2.0.6.
+
+2001-12-17  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fix test for invalid

+
+	* builds/mac/README: Updated.
+
+2001-12-14  Scott Long  <scott@swiftview.com>
+
+	* src/truetype/ttgload.c (load_truetype_glyph): Fixing crash when

+
+2001-12-14  Sam Latinga  <slouken@devolution.com>
+
+	* builds/mac/freetype.make: A new Makefile to build with MPW on
+	MacOS classic.

+2001-12-14  David Turner  <david@freetype.org>
+
+	* src/truetype/ttgload.c (TT_Load_Glyph), src/type1/t1gload.c
+	(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),
+	src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to
+	all font drivers (the advance width was never hinted when it
+	should).
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): New macro.
+	* src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't
+	use `extern' keyword.
+
+2001-12-12  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem
+	psh_globals_new): Adding correct BlueScale/BlueShift support, plus
+	family blues processing.
+	* src/pshinter/pshglob.h (PSH_BluesRec): Updated.
+
+	Started adding support for the Postscript hinter in the CFF module.
+
+	* src/cff/cffgload.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

+	* src/cff/cffgload.h: Updated.
+
+2001-12-12  Werner Lemberg  <wl@gnu.org>

+
+	* src/base/descrip.mms (OBJS): Add ftdebug.obj.
+
+2001-12-11  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/ttload.c (TT_Load_Generic_Header): Typos.
+
+2001-12-11  David Turner  <david@freetype.org>
+
+	* builds/unix/freetype-config.in: Modified the script to prevent
+	passing `-L/usr/lib' to gcc.
+
+	* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').
+
+	* builds/unix/freetype2.m4: New file for checking configure paths.
+	We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I
+	didn't modify builds/unix/install.mk yet.
+
+	* INSTALL: Updated the instructions to build shared libraries with
+	Jam.  They were simply wrong.
+
+	* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused
+	slightly improper results for `FT_Cos' and `FT_Sin' (example:
+	FT_Sin(0) == -1!).
+
+2001-12-11  Detlef Würkner  <TetiSoft@apg.lahn.de>
+
+	* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):

+2001-12-06  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	Added support for reading .dfont files on Mac OS X.  Also added a
+	new routine which looks up a given font by name in the Mac OS and
+	returns the disk file where it resides.
+
+	* src/base/ftmac.c: Include <Files.h> and <TextUtils.h>.
+	(is_dfont): New auxiliary function.
+	(FT_New_Face_From_dfont): New function.

+2001-12-05  David Turner  <david@freetype.org>
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for

+	Comment out use of `origin'.
+
+	* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug
+	where outline shifting wasn't correctly undone after bitmap
+	rasterization.  This created problems with certain glyphs (like '"'
+	of certain fonts) and the cache system.
+
+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.
+	* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.

+	warnings.
+
+	* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:
+	Yet another massive rewrite of the caching sub-system in order to
+	both increase performance and allow simpler cache sub-classing.  As
+	an example, the code for the image and sbit caches is now much
+	simpler.
+
+	I still need to update the documentation in
+	www/freetype2/docs/cache.html to reflect the new design though.
+
+	* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
+	macro.
+	(FT_CACHE_INTERNAL_CACHE_H): Updated.
+
+2001-12-05  David Krause  <freetype@davidkrause.com>
+
+	* docs/license.txt: s/X Windows/X Window System/.
+
+2001-12-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c: Fix definition condition of MEM_Set().

+	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
+	Remove unused variable.

+	ftc_image_node_compare): Remove unused variables.
+	* src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
+	variable.
+	* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
+	compiler warning.
+	* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
+	avoid compiler warnings.
+	* src/pcf/pcfread.c (tableNames): Use `const'.
+	(pcf_read_TOC): Change counter name to avoid compiler warning.
+	Use `const'.
+	* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
+	declaration.
+	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
+	to avoid shadowing.

+	* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
+	and `T1_Size_Done()'.
+
+2001-11-20  Antoine Leca  <antoineleca@multimania.com>
+
+	* include/freetype/ttnameid.h: Added some new Microsoft language
+	codes and LCIDs as found in MSDN (Passport SDK).  Also added
+	comments about the meaning of bit 57 of the `OS/2' table
+	(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is
+	a character beyond 0xFFFF in this font'.  Thanks to Detlef Würkner
+	<TetiSoft@apg.lahn.de> for noticing this.
+
+2001-11-20  David Turner  <david@freetype.org>
+
+	* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting
+	routine that created nasty alignment artefacts.
+
+	* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.
+
+	* src/smooth/ftgrays.c: De-activated experimental gamma support.
+	Apparently, `optimal' gamma tables depend on the monitor type,
+	resolution and general karma, so it's better to compute them outside
+	of the rasterizer itself.
+	(gray_convert_glyph): Use `volatile' keyword.
+
+2001-10-29  David Turner  <david@freetype.org>
+
+	Adding experimental `gamma' support.  This produces smoother glyphs
+	at small sizes for very little cost.
+
+	* src/smooth/ftgrays.c (grays_init_gamma): New function.
+	(gray_raster_new): Use it.
+
+	Various fixes to the auto-hinter.  They merely improve the output of
+	sans-serif fonts.  Note that there are still problems with serifed
+	fonts and composites (accented characters).
+
+	* src/autohint/ahglyph.c (ah_outline_load,
+	ah_outline_link_segments): Implement it.
+	Fix typos.
+	(ah_outline_save, ah_outline_compute_segments): Fix typos.
+	* src/autohint/ahhint.c (ah_align_serif_edge): New argument
+	`vertical'.  Implement improvement.
+	(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
+	Fix typos.
+	(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
+	typos.
+	(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
+	* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
+	* src/autohint/ahtypes.h: Ditto.
+	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
+	(making them global as `ah_debug_disable_horz' and
+	`ah_debug_disable_vert').
+	Fix typos.
+
+	* tests/gview.c: Updated the debugging glyph viewer to show the
+	hints generated by the `autohint' module.
+
+2001-10-27  David Turner  <david@freetype.org>
+
+	* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
+	considerably lowered the performance of the abstract chunk cache.
+
+2001-10-26  David Turner  <david@freetype.org>
+
+	* include/freetype/ftcache.h, include/freetype/cache/*.h,
+	src/cache/*.c: Major re-design of the cache sub-system to provide
+	better performance as well as an `Acquire'/`Release' API.  Seems to
+	work well here, but probably needs a bit more testing.
+
+2001-10-26  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	* builds/mac/README: Updated to reflect my taking over the project
+	and that is now being actively maintained.
+
+	* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
+	<paulm@profoundeffects.com> to support loading a face other than the
+	first from a FOND resource.
+	(FT_New_Face_From_FOND): Updated.
+
+2001-10-25  Leonard Rosenthol  <leonardr@lazerware.com>
+
+	* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac
+	OS for latest version (7) of CWPro and for recent changes to the FT
+	source tree.
+
+2001-10-25  David Turner  <david@freetype.org>
+
+	* include/freetype/config/ftoption.h: Updated comments to explain
+	precisely how to use project-specific macro definitions without
+	modifying this file manually.
+
+	(FT_CONFIG_FORCE_INT64): Define.
+
+	(FT_DEBUG_MEMORY): New macro.
+
+2001-10-24  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.
+
+2001-10-23  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
+	Improvements to the memory debugger to report more information in
+	case of errors.  Also, some allocations that occurred through REALLOC
+	couldn't be previously caught correctly.
+
+	* src/autohint/ahglyph.c (ah_outline_compute_segments,
+	ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
+	src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
+	liberal uses of memset() by the MEM_Set() macro.
+
+2001-10-23  David Turner  <david@freetype.org>
+
+	* src/raster/ftraster.c (Update): Removed to be inlined in ...

+
+2001-10-22  David Turner  <david@freetype.org>
+
+	* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
+	src/base/ftdbgmem.c: Updated the memory debugger and
+	platform-specific implementations of `ftsystem' in order to be able
+	to debug memory allocations on Unix, VMS and Amiga too!
+
+	* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
+	some bogus warnings.
+
+	* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
+	Modified the debugging memory manager to report the location (source
+	file name + line number) where leaked memory blocks are allocated in
+	the source file.
+
+	* src/base/ftdbgmem.c: New debugging memory manager.  You must
+	define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it.  It
+	will record every memory block allocated and report simple errors
+	like memory leaks and double deletes.
+
+	* src/base/Jamfile: Include ftdbgmem.
+	* src/base/rules.mk: Ditto.
+	* src/base/ftbase.c: Include ftdbgmem.c.
+
+	* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY
+	macro definition.
+
+	* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the
+	base component to use the debugging memory manager when the macro
+	FT_DEBUG_MEMORY is defined.
+
+2001-10-21  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
+	we are working with a CID keyed CFF font.  Otherwise, a variable
+	that was never allocated memory might freed.  This is a correction
+	to the previous patch for freeing subfonts.
+
+2001-10-21  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to
+	avoid a memory leak.

+2001-10-21  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
+	src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes

+2001-10-20  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* src/type1/t1load.c (parse_encoding): Add a test to make sure
+	that custom encodings (i.e., neither StandardEncoding nor
+	ExpertEncoding) are not loaded twice when the Type 1 font is
+	synthetic.
+
+	* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
+	for when loading synthetic fonts to make sure that the font name
+	and subroutines are not loaded twice.  This is to remove a memory
+	leak that occurred because the original memory blocks for these
+	objects were not deallocated when the objects were parsed the
+	second time.
+
+2001-10-19  David Turner  <david@freetype.org>
+
+	* src/smooth/ftgrays.c, src/pshinter/pshglob.h,

+	files.
+
+2001-10-18  David Turner  <david@freetype.org>
+
+	* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
+	`glnames.py' script used to generate the `pstables.h' header file.
+	The old one contained a serious bug that made FreeType return
+	incorrect glyph names for certain glyphs.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
+	pixel size from character size to use rounding.  This is an
+	experiment to see whether this gives values similar to Windows for
+	scaled ascent/descent/etc.
+
+	* src/base/ftcalc.c (FT_Div64by32): Changed the implementation
+	slightly since the original code was mis-compiled on Mac machines
+	using the MPW C compiler.
+
+	* src/base/ftobjs.c (FT_Realloc): When a memory block was grown
+	through FT_Realloc(), the new bytes were not set to 0, which created
+	some strange bugs in the PostScript hinter.
+	(destroy_face): Don't deallocate unconditionally.
+
+	* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
+	Adding support to new PostScript hinter.

+	src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,
+	src/type1/t1objs.h: Updates to use the new PostScript hinter.
+
+	* tests/Jamfile, tests/gview.c: Adding a new glyph hinting
+	viewer/debugger to the source tree.  Note that you will _not_ be
+	able to compile it since it depends on an unavailable graphics
+	library named `Nirvana' to render vector images.
+
+2001-10-17  David Turner  <david@freetype.org>
+
+
+	* Version 2.0.5 released.

+	Fixed a bug in `glnames.py' that prevented it from generating
+	correct glyph names tables.  This resulted in the unavailability of
+	certain glyphs like `Cacute', `cacute' and `lslash' in Unicode

+	this is used in embedded fonts.
+
+	* src/psaux/psobjs.c (PS_Table_Add): Fixed a reallocation bug that
+	generated a dangling pointer reference.
+
+2001-08-30  Anthony Feik  <afeick@hotmail.com>

+
+	* include/freetype/internal/cfferrs.h,
+	include/freetype/internal/tterrors.h,
+	include/freetype/internal/t1errors.h: Removed.  Replaced with files

+
+	Fixed the incorrect blue zone computations, and improved the

+	* builds/freetype.mk: Fixed a problem with object deletions under
+	Dos/Windows/OS/2 systems.

+	at the footer of each web page (useful to distinguish between
+	versions).
+
+	* Jamfile: Fixed incorrect HDRMACRO argument.
+
+	* TODO: Removed the cubic arc bbox computation note, since it has been
+	fixed recently.
+	* src/base/ftbbox.c (test_cubic_zero): Renamed to...

+	Fixed the Bézier stack depths.
+
+	* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.

+
+	* ftconfig.h, ftoption.h: Updated `ftconfig.h' to detect 64-bit int

+	finding this out.
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixed memory leak when

+	* src/cff/cffparse.c (cff_parse_font_matrix): Added logic to get
+	the units_per_EM from the FontMatrix.
+
+	(cff_parse_fixed_thousand): New function.  Gets a real number from
+	the CFF font, but multiplies by 1000 (this is to avoid rounding

+
+	(cff_parse_real): Added code so that the integer part is moved

+	units_per_EM from the font matrix.
+
+	(parse_dict): Deleted test to see whether the FontInfo keyword has
+	been seen.  Deletion of this test allows fonts without FontInfo
+	dictionaries to be parsed by the Type 1 driver.
+
+	(T1_Open_Face): Deleted empty subroutines array test to make sure
+	fonts with no subroutines still are parsed.
+
+2001-01-17  Francesco Zappa Nardelli  <francesco.zappa.nardelli@ens.fr>

+	t2types.h and made this the canonical `types' header for the CFF
+	driver.
+
+	* include/freetype/internal/t2types.h: This file was merged with
+	cfftypes.h and is no longer necessary.
+
+	* include/freetype/internal/t2errors.h:	Renamed to cfferrs.h.

+	    cff_expert_charset
+	    cff_expertsubset_charset

+
+	* src/cff/t2gload.c (T2_Load_Glyph): Added code	so that the font
+	transform is applied.
+
+	* src/cff/cffparse.c (cff_parse_font_matrix): Added code so that

+
+	* src/autohint/ahhint.c (ah_hinter_load, ah_hinter_load_glyph):

+
+	* *.mk: Added lots of `.PHONY' targets.
+
+2000-12-17  Karsten Fleischer  <kfleisc1@ford.com>

+
+	* INSTALL: Added info about makepp.
+
+2000-12-14  David Turner  <david.turner@freetype.org>

+	* INSTALL: Updated installation instructions on Win32, listing the
+	new `make setup list' target used to list supported
+	compilers/targets.
+
+	* src/raster/ftraster.c (ft_black_render): Test for unsupported

+
+2000-12-13  David Turner  <david.turner@freetype.org>
+
+	* include/freetype/config/ft2build.h,
+	include/freetype/internal/internal.h: Fixed header inclusion macros

+	* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.
+
+	* builds/win32/detect.mk: Added support for the Intel C/C++

+2000-12-12  Werner Lemberg  <wl@gnu.org>

+	Removed.  ANSI C doesn't (explicitly) allow macro expansion in
+	arguments using `##'.
+	(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
+	names directly.  Make them configurable.  Use `##' to strip leading
+	and trailing spaces from arguments.
+
+	* builds/unix/ft2unix.h: Adapted.
+
+	* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,

+
+2000-12-08  Werner Lemberg  <wl@gnu.org>

+
+2000-12-06  Werner Lemberg  <wl@gnu.org>
+

+
+	* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
+	an occasional crash when the function was called (due to a dangling
+	pointer).
+
+	* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
+	The ANSI `free()' function was called instead of `memory->free()'.
+
+	* docs/docmaker.py: Added section filtering, multi-page generation
+	(index page generation is still missing though).
+
+2000-12-04  David Turner  <david.turner@freetype.org>
+
+	* builds/unix/install.mk, builds/unix/ft2unix.h: The file `ft2unix.h'
+	is now installed as <ft2build.h> for Unix systems.  Note that we
+	still use the `freetype2/freetype' installation path for now.
+
+	* */*.[ch]: Now using <ft2build.h> as the default build and setup
+	configuration file in all public headers.  Internal source files
+	still need some changes though.
+
+	* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new

+
+2000-11-30  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (.PHONY): Adding `distclean'.
+	* builds/unix/detect.mk (.PHONY): Adding `devel', `unix', `lcc',
+	`setup'.
+
+2000-11-30  David Turner  <david.turner@freetype.org>
+
+	* INSTALL: Slightly updated the quick starter documentation to
+	include IDE compilation, prevent against BSD Make, and specify `make
+	setup' instead of a single `make' for build configuration.
+
+	* include/config/ftbuild.h, include/internal/internal.h: Added new
+	configuration files used to determine the location of all public,
+	configuration, and internal header files for FreeType 2.  Modified
+	all headers under `include/freetype' to reflect this change.  Note
+	that we still need to change the library source files themselves
+	though.
+
+	* builds/compiler/bcc.mk, builds/compiler/bcc-dev.mk,
+	builds/win32/w32-bcc.mk, builds/win32/w32-bccd.mk,
+	builds/win32/detect.mk: Added new files to support compilation with
+	the free Borland C++ command-line compiler.  Modified the detection
+	rules to recognize the new `bcc32' target in `make setup bcc32'.
+
+	* src/sfnt/ttcmap.c, src/sfnt/ttpost.c, src/sfnt/ttsbit.c,
+	src/truetype/ttobjs.c, src/truetype/ttgload.c,
+	src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
+	didn't really like.  Basically, this compiler complains when FT_UInt
+	is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
+	in these cases).
+
+2000-11-30  Tom Kacvinsky  <tkacvins@freetype.org>
+
+	* t2objs.c (T2_Init_Face): Added calculation of `face->height' for

+
+	Say you have `(Foo*)x' and want to assign, pass, or return it as
+	`(Bar*)'.  If you simply say `x' or `(Bar*)x', then the C compiler
+	would warn you that type casting incompatible pointer types breaks
+	strict-aliasing.  The solution is to cast to `(void*)' instead which
+	is the generic pointer type, so the compiler knows that it should
+	make no strict-aliasing assumption on `x'.  But the problem with
+	`(void*)x' is that seems like in C++, unlike C, `void*' is not a
+	generic pointer type and assigning `void*' to `Bar*' without a cast
+	causes an error.  The solution is to cast to `Bar*' too, with
+	`(Bar*)(void*)x' as the result -- this is what the patch does.
+
+	* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
+	include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove

+	* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
+	FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),

+	to not break strict aliasing.
+
+	* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.
+
+	* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.
+
+2005-05-23  David Turner  <dturner@freetype.org>

+	files.  The idea is to avoid loading and decoding tables in the
+	heap, and instead access the raw data whenever possible (i.e., when
+	it doesn't compromise performance).
+
+	This has several benefits: For example, opening vera.ttf now uses
+	just a small amount of memory (even when the FT_Library footprint is
+	accounted for), until you start loading glyphs.  Even then, you save
+	at least 20KB compared to the non-optimized case.  Performance of
+	various operations, including open and close, has also been
+	dramatically improved.
+
+	More optimizations to come, especially for the auto-hinter.

+2004-07-11  David Turner  <david@freetype.org>
+
+	Fix bugs that prevented the stroker to correctly generate stroked
+	paths from closed paths, i.e., nearly all glyphs in vectorial fonts.
+
+	The code is still _very_ buggy though; treat with special care.
+
+	* src/base/ftstroke.c (FT_STROKE_TAG_BEGIN_END): New macro.
+	(ft_stroke_border_reverse): New function.
+	(ft_stroker_inside): Remove local variable `sigma'; use different

+2004-06-24  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.9 released.
+	=========================
+
+
+	* src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing
+	compiler warnings.
+
+2004-06-23  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare
+	FT_QAlloc_Debug and FT_QRealloc_Debug.
+
+	* src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.
+	(FT_QRealloc): Call FT_QAlloc if original pointer is NULL.
+	Fix error message.
+
+2004-06-23  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/ftmemory.h, src/base/ftutil.c
+	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,
+	FT_QRealloc_Debug): New functions that perform allocation without
+	zero-ing out the corresponding blocks.
+
+	* include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,
+	FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,
+	FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY,
+	FT_QRENEW_ARRAY): New macros.
+
+	* src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC.

+	tt_face_load_gasp): Use FT_QNEW_ARRAY.
+	(tt_face_load_kern): Use FT_QNEW_ARRAY.
+	Small optimization in the kerning table verifier; this speeds up
+	TrueType face opening by about 7%.
+	(tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC.
+
+	* include/freetype/config/ftmodule.h: Changed the order of modules,
+	putting TrueType and Type 1 first.  This dramatically improves the
+	performance of face open/close operations.  For example, putting the
+	TrueType driver first in the list results in a 5x speedup when
+	opening `Vera.ttf'.
+
+	The very problem is that both the PCF and BDF drivers do a lot more
+	than necessary to detect that they cannot handle a font file.
+
+2004-06-22  Werner Lemberg  <wl@gnu.org>

+	load_truetype_glyph): Don't access (unrounded)
+	`TT_Size.root.metrics' but (rounded) `TT_Size.metrics'.  This fixes
+	a scaling bug that caused incorrect rendering when the bytecode
+	interpreter was enabled.

+
+2004-06-04  David Turner  <david@freetype.org>
+
+	* src/autofit/*: Important fixes to the auto-fitter.  The output
+	now seems to be 100% equivalent to the auto-hinter, while being
+	about 2% faster (which proves that script-specific algorithm
+	selection isn't a performance problem).
+
+	To test it, change `autohint' to `autofit' in
+	<freetype/config/ftmodule.h> and recompile.
+
+	A few more testing is needed before making this the official
+	auto-hinting module.

+
+2004-02-10  Werner Lemberg  <wl@gnu.org>
+
+	Make the PS parser more tolerant w.r.t. non-standard font data.  In
+	general, an error is only reported in case of a syntax error; a
+	wrong type is now simply ignored (if possible).  To be independent
+	of the order of various MM-specific keywords, the parse_shared_dict
+	routine has been removed -- the PS parser is now capable to skip
+	this data.  It no longer fails on parsing e.g.
+
+	  dup /WeightVector exch def
+
+	Since the token following /WeightVector isn't `[' (starting an
+	array) it is simply ignored.
+
+	* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a
+	new internal error value.
+
+	* src/type1/t1load.c (parse_blend_axis_types,
+	parse_blend_design_positions, parse_blend_design_map): Return
+	T1_Err_Ignore if no proper array is following the keyword.
+	(parse_weight_vector): Use T1_ToTokenArray, initializing `blend'
+	structure, if necessary.
+	Return T1_Err_Ignore if no proper array is following the keyword.
+	(parse_shared_dict): Removed.
+	(parse_encoding): Set parser->root.error to return T1_Err_Ignore
+	if no result can be obtained.
+	Check for errors before accessing `elements' array.
+	(t1_keywords): Remove /shareddict.
+	(parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.
+	Set keyword_flag only in case of success.
+	Check error code if skipping an unrecognized token.
+	(T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend
+	if blend commands haven't set up a proper MM font.
+
+	* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special
+	code for synthetic fonts.
+	Return PSaux_Err_Ignore if no proper value has been found.
+
+2004-02-09  Werner Lemberg  <wl@gnu.org>

+
+	* builds/unix/configure.in: Call AC_SUBST for `enable_shared',

+	* builds/unix/configure: Regenerated.
+
+	* builds/unix/freetype-config.in: Make --prefix and --exec-prefix
+	actually work.
+	Report a proper --rpath (or -R) value for --libs argument if a
+	shared library has been built.
+
+	* docs/CHANGES: Updated.
+
+2004-02-07  Keith Packard  <keithp@keithp.com>
+
+	* src/bdf/bdfdrivr.c (BDF_Face_Init, BDF_Set_Pixel_Size): Fix
+	computation of various vertical and horizontal metric values.
+
+	* src/pcfdrivr.c (PCF_Set_Pixel_Size), src/pcfread (pcf_load_font):
+	Ditto.
+
+2004-02-07  Werner Lemberg  <wl@gnu.org>
+
+	* builds/win32/visualc/index.html,

+
+2004-02-02  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_dict): Handle `RD' and `-|' commands
+	outside of /Subrs or /CharStrings.  This can happen if there is
+	additional code manipulating those two arrays so that FreeType
+	doesn't recognize them properly.
+	(T1_Open_Face): Improve an error message.
+
+2004-02-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_charstrings): Exit immediately if
+	there are no elements in /CharStrings.  This is needed for fonts
+	like Optima-Oblique which not only define /CharStrings but access it
+	also.
+
+2004-02-01  David Turner  <david@freetype.org>
+
+	* src/sfnt/Jamfile: Removing `ttcmap' from the list of sources.

+	<FTC_INLINE>: Ditto.
+	Use FTC_MRULIST_LOOKUP_CMP.
+	* include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): New
+	macro.
+	(FTC_MRULIST_LOOKUP): Use it.
+
+	* src/cache/Jamfile (_sources), src/cache/descrip.mms: Updated.
+	* src/cache/ftcbasic.c: Fix compiler warnings.

+	heavy testing).
+
+	* Jamfile: Updating `refdoc' target, and adding `autohint' to the
+	list of modules to build.  Both the autohinter and autofitter will
+	be built by default.  But which one will be used is determined by
+	the content of `ftmodule.h'.
+
+	* src/autofit/*: Many updates, but the code is still buggy...
+
+2004-01-31  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.c (cff_operator_seac): Fix magnitude of
+	accent offset.
+	Update code similarly to the seac support for Type 1 fonts.
+	(cff_decoder_parse_charstrings) <cff_op_endchar>: Fix magnitude
+	of accent offset.
+	Don't hint glyphs twice if seac is emulated.
+	<cff_op_flex>: Assign correct point tags.
+	* docs/CHANGES: Updated.
+
+2004-01-30  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1parse.c (T1_Get_Private_Dict): Use FT_MEM_MOVE, not
+	FT_MEM_COPY, for copying the private dict.
+
+	* src/type1/t1load.c (parse_subrs): Assign number of subrs only
+	in first run.
+	(parse_charstrings): Parse /CharStrings in second run without
+	assigning values.
+	(parse_dict): Skip all /CharStrings arrays but the first.  We need
+	this for non-standard fonts like `Optima' which have different
+	outlines depending on the resolution.  Note that there is no
+	guarantee that we get fitting /Subrs and /CharStrings arrays; this
+	can only be done by a real PS interpreter.
+
+2004-01-29  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* builds/win32/visualc/index.html: New file, giving detailed

+	(cid_face_open): Add new argument `face_index' to return quickly
+	if less than zero.  Updated all callers.

+	`face->cid_stream' if `parser->binary_length' is non-zero.
+	* src/cid/cidload.h: Updated.
+
+	* src/cid/cidobjs.c (cid_face_done): Free `binary_data' and
+	`cid_stream'.
+
+	* src/cid/cidparse.c (cid_parser_new): Check arguments to

+
+	  *Complete* rewrite of the cache sub-system to `solve' the
+	  following points:
+
+	    - all public APIs have been moved to FT_CACHE_H, everything
+	      under `include/freetype/cache' is only needed by client
+	      applications that want to implement their own caches
+
+	    - a new function named FTC_Manager_RemoveFaceID to deal
+	      with the uninstallation of FaceIDs
+
+	    - the image and sbit cache are now abstract classes, that
+	      can be extended much more easily by client applications
+
+	    - better performance in certain areas.  Further optimizations
+	      to come shortly anyway...
+
+	    - the FTC_CMapCache_Lookup function has changed its signature,
+	      charmaps can now only be retrieved by index
+
+	    - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
+	      FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
+	      private header for the moment)

+	code from type1 module to handle this.
+	(t42_parse_dict): Updated to use new PostScript parser routines
+	from psaux.
+	Remove code for synthetic fonts (which can't occur in Type 42

+
+	A new try to synchronize bitmap font access.
+
+	* include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
+	defined to return the baseline-to-baseline distance.  This was
+	already the value returned by the BDF and PCF drivers.
+
+	The `width' field now gives the average width.  I wasn't able to

+
+	New fields `size', `x_ppem', and `y_ppem'.

+2003-06-29  Werner Lemberg  <wl@gnu.org>
+
+	Redesigning the FNT driver to return multiple faces, not multiple
+	strikes.  At least one font (app850.fon from WinME) contains
+	different FNT charmaps for its subfonts.  Consequently, the previous
+	design of having multiple bitmap strikes in a single font face fails
+	since we have only one charmap per face.
+
+	* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.

+	Fix glyph index computation.
+	(winfnt_driver_class): Updated.
+
+2003-06-25  Owen Taylor  <otaylor@redhat.com>

+
+	Synchronize computation of height and width for bitmap strikes.  The

+

+
+	Completely revised FreeType's make management.
+
+	. In all makefiles `/' is used as the path separator.  The
+	  conversion to the real path separators is done as late as
+	  possible using $(subst ...).
+
+	. $(HOSTSEP) no longer exists.  Now, $(SEP) gives the path separator
+	  for the operating system, and the new $(COMPILER_SEP) the path
+	  separator for the compiler tools.
+
+	. $(BUILD) has been renamed to $(BUILD_DIR).  In general, all
+	  directory variables end with `_DIR'.  The variants ending in `_'
+	  (like `BASE_' have been removed).
+
+	The following ChangeLog entries only describe changes which are
+	not related to the redesign.

+
+	* include/freetype/config/ftoption.h: Defining

+
+	* src/truetype/ttgload.c (load_truetype_glyph)

+
+2003-04-25:  Graham Asher  <graham.asher@btinternet.com>
+
+	Added the optional unpatented hinting system for TrueType.  It
+	allows typefaces which need hinting to produce correct glyph forms
+	(e.g., Chinese typefaces from Dynalab) to work acceptably without
+	infringing Apple patents.  This system is compiled only if
+	TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in
+	ftoption.h.

+	* include/freetype/ttunpat.h: New file.  Defines
+	FT_PARAM_TAG_UNPATENTED_HINTING.

+	similar to the PCF driver.
+	* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
+	Updated.
+
+	* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
+	is declared twice.  It is perhaps better to modify the zlib source
+	files directly instead of this hack.
+	(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
+	to make build with g++ successful.
+
+2003-04-24  Manish Singh  <yosh@gimp.org>

+
+2003-04-24  David Turner  <david@freetype.org>
+
+	* src/pcf/pcfread.c (pcf_load_font): Fixed the computation of
+	face->num_glyphs.  We must increase the value by 1 to respect the
+	convention that glyph index 0 always corresponds to the `missing
+	glyph'.
+
+2003-04-24  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/unix-cc.in (CFLAGS): Add @CPPFLAGS@.

+2003-04-23  Akito Hirai  <akito@kde.gr.jp>
+
+	* src/sfnt/ttcmap0.c (tt_cmap4_validate): Provide a weak variant
+	of the glyph ID bounding check if FT_VALIDATE_TIGHT is not active.
+	Without this change, many CJK fonts from Dynalab are rejected.
+
+2003-04-23  Joe Marcus Clarke  <marcus@FreeBSD.org>
+
+	* src/base/ftbdf.c (FT_Get_BDF_Property): Check for valid

+
+	* src/base/ftmac.c (parse_fond): Fix handling of style names.
+
+2003-04-23  Werner Lemberg  <wl@gnu.org>
+
+	* src/pfr/pfrload.c (pfr_extra_item_load_font_id): Use FT_PtrDist

+	bug that had nasty consequences when trying to open an `invalid'
+	font on a Mac.
+
+2003-04-09  Mike Fabian  <mfabian@suse.de>
+
+	* src/bdf/bdfdrivr.h (BDF_encoding_el), src/pcf/pcf.h
+	(PCF_EncodingRec): Changed FT_Short to FT_UShort in order to be able
+	to access more than 32768 glyphs in fonts.

+2003-04-08  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.4 released.
+	=========================
+
+
+2003-04-03  Martin Muskens  <mmuskens@aurelon.com>
+
+	* src/type1/t1load.c (T1_Open_Face): Fixed the code to make it
+	handle special cases where a font only contains a `.notdef' glyph
+	(happens in PDF-embedded fonts).  Otherwise, FT_Panic was called.
+
+2003-03-27  David Turner  <david@freetype.org>
+
+	* README: Updated.
+
+	* README.UNX: Removed (now replaced by docs/INSTALL.UNX).
+
+	* src/pshinter/pshalgo3.c: The hinter now performs as in 2.1.3 and
+	will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is
+	used.
+	(psh3_dimension_quantize_len): Enabled.
+	(psh3_hint_align): Enable commented code.
+	(psh3_hint_align_light): Commented out.
+
+	* src/base/ftobjs.c (FT_Set_Char_Size): Changed the default

+	provide accurate kerning data when native TrueType hinting is
+	enabled.
+
+	* src/type1/t1load.c (is_name_char): The Type 1 loader now accepts
+	more general names according to the PostScript specification (the
+	previous one was too restrictive).
+	(parse_font_name, parse_encoding, parse_charstrings, parse_dict):
+	Use `is_name_char'.
+	(parse_subrs): Handle empty arrays.
+
+2003-03-20  David Turner  <david@freetype.org>
+
+	Serious rewriting of the documentation.

+	FT_GlyphSlot objects:
+
+	  ft_glyphslot_free_bitmap

+
+	These functions are much more convenient to use than managing the
+	FT_GLYPH_OWN_BITMAP flag manually.

+	`ft_glyphslot_alloc_bitmap'.
+
+	* src/sfnt/ttsbit.c (Load_SBit_Image): Change 5th argument to type
+	`FT_GlyphSlot'.
+	Adding argument `depth' to handle recursive calls.
+	Use `ft_glyphslot_alloc_bitmap'.

+
+	* src/winfonts/winfnt.c (FNT_Load_Glyph): Use

+
+2003-03-15  David Turner  <david@freetype.org>
+

+	bug.  Actually, it seems that previous versions of FreeType didn't
+	perform TrueType rounding exactly as appropriate.
+
+2003-03-14  David Turner  <david@freetype.org>
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixing the small
+	TrueType native rendering glitches; they came from a small rounding
+	error.
+
+2003-03-13  David Turner  <david@freetype.org>
+
+	Added new environment variables to control memory debugging with
+	FreeType.  See the description of `FT2_DEBUG_MEMORY',
+	`FT2_ALLOC_TOTAL_MAX' and `FT2_ALLOC_COUNT_MAX' in DEBUG.TXT.
+
+	* src/base/ftdbgmem.c (FT_MemTableRec): Add `alloc_count',

+	an out-of-memory condition.
+
+	* src/smooth/ftgrays.c (gray_convert_glyph): Removed compiler
+	warnings / volatile bug.
+
+	* src/truetype/ttobjs.c (tt_glyphzone_done): Removed segmentation
+	fault that happened in tight memory environments.
+
+2003-02-28  Pixel  <pixel@mandrakesoft.com>
+

+
+2003-02-25  Anthony Fok  <anthony@thizlinux.com>
+

+
+	* src/sfnt/ttload.c, src/base/ftobjs.c: Changed `asian' to `Asian'
+	in comments.
+
+2003-02-25  David Turner  <david@freetype.org>
+
+	* src/gzip/ftgzip.c (ft_gzip_file_fill_output): Fixed a bug that
+	caused FreeType to loop endlessly when trying to read certain
+	compressed gzip files.  The following test reveals the bug:
+
+	  touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
+
+	Several fixes to the PFR font driver:
+
+	- The list of available embedded bitmaps was not correctly set in
+	  the root FT_FaceRec structure describing the face.
+
+	- The glyph loader always tried to load the outlines when
+	  FT_LOAD_SBITS_ONLY was specified.
+
+	- The table loaded now scans for *undocumented* elements of a
+	  physical font's auxiliary data record.  This is necessary to
+	  retrieve the `real' family and style names.
+
+	NOTE THAT THESE CHANGES THE FAMILY NAME OF MANY PFR FONTS!
+
+	* src/pfr/pfrload.c (pfr_aux_name_load): New function.
+	(pfr_phy_font_done): Free `family_name' and `style_name' also.
+	Remove unused variables.
+	(pfr_phy_font_load): Extract useful information from the auxiliary
+	bytes.
+
+	* src/pfr/pfrobjs.c (pfr_face_done): Set pointers to NULL.
+	(pfr_face_init): Provide fallback values for `family_name' and
+	`style_name'.
+	Handle strikes.
+	(pfr_slot_load): Handle FT_LOAD_SBITS_ONLY.
+	* src/pfr/pfrtypes.h (PFR_PhyFontRec): Add fields `ascent',
+	`descent', `leading', `family_name', and `style_name'.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): Fixed a rounding bug
+	when computing the scale factors for a given character size in
+	points with resolution.
+
+	* devel/ft2build.h, devel/ftoption.h: New files (in a new directory)
+	which are special development versions of include/ft2build.h and
+	include/freetype/config/ftoption.h, respectively.
+
+2003-02-18  David Turner  <david@freetype.org>
+
+	Fixing the slight distortion problem that occurred due to the latest
+	auto-hinter changes.
+
+	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Fix rounding.
+
+	* src/truetype/ttdriver.c (Set_Char_Sizes): New variable `metrics2'.
+	[!TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Removed.
+
+	* src/truetype/ttobjs.h (TT_SizeRec): New field `metrics'.
+	* src/truetype/ttobjs.c (Reset_Outline_Size): Fix initialization of
+	`metrics'.
+	[FT_CONFIG_CHESTER_ASCENDER]: Code removed.
+	(Reset_SBit_Size): Fix initialization of `metrics'.
+
+	* src/truetype/ttinterp.c (TT_Load_Context): Fix initialization of
+	`exec->metrics'.
+
+	* src/autohint/ahhint.c (ah_hinter_load): Disabled the advance width
+	`correction' which seemed to provide more trouble than benefits.
+
+2003-02-13  Graham Asher  <graham.asher@btinternet.com>
+
+	Changed the incremental loading interface in a way that makes it
+	simpler and allows glyph metrics to be changed (e.g., by adding a
+	constant, as required by CFF fonts) rather than just overridden.
+	This was required to make the GhostScript-to-FreeType bridge work.
+
+	* src/cff/cffgload.c (cff_slot_load) [FT_CONFIG_OPTION_INCREMENTAL]:
+	Allow metrics to be overridden.
+	* src/cid/cidgload.c (cid_load_glyph) [FT_CONFIG_OPTION_INCREMENTAL]:
+	Ditto.
+
+	* src/truetype/ttgload.c (load_truetype_glyph)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Simplify.
+	(compute_glyph_metrics) [FT_CONFIG_OPTION_INCREMENTAL]: Code block
+	moved down.
+
+	* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Updated.
+
+	* include/freetype/ftincrem.h: Updated.
+
+2003-01-31  David Turner  <david@freetype.org>
+
+	* docs/CHANGES, docs/VERSION.DLL, docs/TODO: Updating documentation
+	for the 2.1.4 release.
+
+	* builds/win32/visualc/freetype.dsp,
+	builds/win32/visualc/index.html: Updating the project file for
+	2.1.4.
+
+	* src/gzip/adler32.c, src/gzip/ftgzip.c, src/gzip/infblock.c,
+	src/gzip/infcodes.c, src/gzip/inflate.c, src/gzip/inftrees.c,
+	src/gzip/infutil.c: Removed old-style (K&R)function definitions.
+	This avoids warnings with Visual C++ at its most pedantic mode.
+
+	* src/pfr/pfrsbit.c: Removed compiler warnings.
+
+	* src/cache/ftccmap.c (ftc_cmap_family_init): Changed an FT_ERROR
+	into an FT_TRACE1 since it caused `ftview' and others to dump too
+	much junk when trying to display a waterfall with a font without a
+	Unicode charmap (e.g.  SYMBOL.TTF).
+
+	Implemented FT_CONFIG_CHESTER_BLUE_SCALE, corresponding to the last
+	patch from David Chester, but with a much simpler (and saner)
+	implementation.
+
+	* src/autohint/ahhint.c (ah_hinter_load_glyph)
+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Try to optimize the y_scale so that
+	the top of non-capital letters is aligned on a pixel boundary
+	whenever possible.
+
+	* src/base/ftobjs.c (FT_Set_Char_Size)
+	[FT_CONFIG_CHESTER_BLUE_SCALE]: Round differently.
+	* src/truetype/ttdriver.c (Set_Char_Sizes)
+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Do some rounding only
+	if this macro is defined.
+
+	* src/truetype/ttobjs.c (Reset_Outline_Size)
+	[FT_CONFIG_CHESTER_ASCENDER]: Round differently.
+
+	* src/pshinter/pshalgo3.c: Improved the Postscript hinter.  Getting
+	rid of stem snapping seems to work well here (though the stems are
+	still slightly moved to increase contrast).
+	(psh3_dimension_quantize_len): Commented out.
+	(psh3_hint_align_light): New function.
+	(psh3_hint_align): Comment out some code.
+
+	THIS IMPROVES ANTI-ALIASED RENDERING, BUT MONOCHROME AND LCD MODES
+	STILL SUCK.
+
+2003-01-22  David Chester  <davidchester@qmx.net>
+
+	* src/autohint/ahhint.c (ah_compute_stem_width): Small fix to the
+	stem width optimization.
+
+2003-01-22  David Turner  <david@freetype.org>
+
+	Adding a new API `FT_Get_BDF_Property' to retrieve the BDF
+	properties of a given PCF or BDF font.
+
+	* include/freetype/ftbdf.h (BDF_PropertyType): New enumeration.
+	(BDF_Property, BDF_PropertyRec): New structure.
+	FT_Get_BDF_Property): New function.
+	* include/freetype/internal/bdftypes.h: Include FT_BDF_H.
+	(BDF_GetPropertyFunc): New function pointer.
+
+	* src/base/ftbdf.c (test_font_type): New helper function.
+	(FT_Get_BDF_Charset_ID): Use `test_font_type'.
+	(FT_Get_BDF_Property): New function.
+
+	* src/bdf/bdfdrivr.c: Include FT_BDF_H.
+	(bdf_get_bdf_property, bdf_driver_requester): New functions.
+	(bdf_driver_class): Use `bdf_driver_requester'.
+
+	* src/pcf/pcfdrivr.c: Include FT_BDF_H.
+	(pcf_get_bdf_property, pcf_driver_requester): New functions
+	(pcf_driver_class): Use `pcf_driver_requester'.
+
+	* src/pcf/pcfread.c: Include `pcfread.h'.
+	(pcf_find_property): Decorate it with FT_LOCAL_DEF.
+	* src/pcf/pcfread.h: New file, providing `pcf_find_property'.
+
+	* src/sfnt/ttload.c (sfnt_dir_check): Relaxed the `head' table size
+	verification to accept a few broken fonts who pad the size
+	incorrectly (the table should be padded, but its `size' field
+	shouldn't according to the specification).
+
+2003-01-18  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/ltmain.sh: Regenerated with `libtoolize --force
+	--copy' from libtool 1.4.3.
+	* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
+	automake 1.7.1.
+	* builds/unix/configure: Regenerated with autoconf 2.54.
+	* builds/unix/config.guess, builds/unix/config.sub: Updated from
+	`config' CVS module at subversions.gnu.org.
+	* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
+	`automake' CVS module at subversions.gnu.org.
+
+2003-01-15  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h: Fixed documentation for
+	FT_Size_Metrics.
+
+2003-01-15  James Su  <suzhe@turbolinux.com.cn>
+
+	* src/gzip/ftgzip.c (ft_gzip_check_header): Bugfix: couldn't read
+	certain gzip-ed font files (typo: `&&' -> `&').
+
+2003-01-15  Huw D M Davies  <h.davies1@physics.ox.ac.uk>
+
+	Added a Windows .FNT specific API (mostly for Wine).  Also fixed a
+	nasty bug in the header loader which would cause invalid memory
+	overwrites.
+
+	* include/freetype/config/ftheader.h (FT_WINFONTS_H): New macro
+	for ftwinfnt.h.
+	* include/freetype/internal/fnttypes.h: Include FT_WINFONTS_H.
+	(FNT_FontRec): Updated.
+	Move Windows FNT definition to...
+	* include/freetype/ftwinfnt.h: This new file.
+	(FT_WinFNT_HeaderRec): Rename `reserved2' to `reserved1'.
+	* src/base/ftwinfnt.c: New file, providing `FT_Get_WinFNT_Header'.
+	* src/winfonts/winfnt.c (winfnt_header_fields): Updated.
+	Rename `reserved2' to `reserved1'.
+	(fnt_font_load): Updated.
+
+	* src/base/Jamfile, src/base/descrip.mms, src/base/rules.mk:
+	Updated.
+
+2003-01-14  Graham Asher  <graham.asher@btinternet.com>
+
+	* include/freetype/ftglyph.h, src/base/ftglyph.c: Added `const' to
+	the type of the first argument to FT_Matrix_Multiply, which isn't
+	changed -- this adds documentation and convenience.
+
+2003-01-13  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/sfnt/ttload.c (tt_face_load_metrics)
+	[FT_CONFIG_OPTION_INCREMENTAL]: TrueType typefaces without
+	horizontal metrics (without the `hmtx' table) are now tolerated if
+	an incremental interface has been specified that has a
+	get_glyph_metrics function, implying that metrics will be supplied
+	from outside.  This happens for certain Type 42 fonts passed from
+	GhostScript.
+
+2003-01-11  David Chester  <davidchester@qmx.net>
+
+	Patches to the auto-hinter in order to slightly improve the output.
+	Note that everything is controlled through the new
+	FT_CONFIG_OPTION_CHESTER_HINTS defined in `ftoption.h'.  There are
+	also individual FT_CONFIG_CHESTER_XXX macros to control individual
+	`features'.
+
+	Note that all improvements are enabled by default, but can be
+	tweaked for optimization and testing purposes.  The configuration
+	macros will most likely disappear in the short future.
+
+	* include/freetype/config/ftoption.h
+	(FT_CONFIG_OPTION_CHESTER_HINTS): New macro.
+	(FT_CONFIG_CHESTER_{SMALL_F,ASCENDER,SERIF,STEM,BLUE_SCALE})
+	[FT_CONFIG_OPTION_CHESTER_HINTS]: New macros to control individual
+	features.
+
+	* src/autohint/ahglobal.c (blue_chars) [FT_CONFIG_CHESTER_SMALL_F]:
+	Add blue zone for `fijkdbh'.
+	* src/autohint/ahglobal.h (AH_IS_TOP_BLUE)
+	[FT_CONFIG_CHESTER_SMALL_F]: Use `AH_BLUE_SMALL_F_TOP'.
+	* src/autohint/ahglyph.c (ah_outline_compute_edges)
+	[FT_CONFIG_CHESTER_SERIF]: Use `AH_EDGE_SERIF'.
+	(ah_outline_compute_blue_edges) [FT_CONFIG_CHESTER_SMALL_F]:
+	Increase threshold for `best_dist'.
+	* src/autohint/ahhint.c (ah_compute_stem_width)
+	[FT_CONFIG_CHESTER_SERIF]: Provide new version for improved serif
+	handling.
+	(ah_align_linked_edge) [FT_CONFIG_CHESTER_SERIF]: Use special
+	version of `ah_compute_stem_width'.
+	(ah_hint_edges_3) [FT_CONFIG_CHESTER_STEM]: A new algorithm for stem
+	alignment when stem widths are less than 1.5 pixels wide centers the
+	stem slightly off-center of the center of a pixel (this increases
+	sharpness and consistency).
+	[FT_CONFIG_CHESTER_SERIF]: Use special version of
+	`ah_compute_stem_width'.
+	* src/autohint/ahtypes.h [FT_CONFIG_CHESTER_SMALL_F]: Add
+	`AH_BLUE_SMALL_F_TOP'.
+
+2003-01-11  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/fnttypes.h (WinFNT_HeaderRec): Increase
+	size of `reserved2' to avoid memory overwrites.
+
+2003-01-08  Huw Davies  <huw@codeweavers.com>
+
+	* src/winfonts/winfnt.c (winfnt_header_fields): Read 16 bytes into
+	`reserved2', not `reserved'.
+
+	* src/base/ftobjs.c (find_unicode_charmap): Fixed the error code
+	returned when the font doesn't contain a Unicode charmap.  This
+	allows FT2 to load `symbol.ttf' and a few others correctly since the
+	last release.
+	(open_face): Fix return value.
+
+2003-01-08  Owen Taylor  <owen@redhat.com>
+
+	Implemented the FT_RENDER_MODE_LIGHT hinting mode in the auto and
+	postscript hinters.
+
+	* src/autohint/ahtypes.h (AH_HinterRec): Add `do_stem_adjust'.
+	* src/autohint/ahhint.c (ah_compute_stem_width): Handle
+	hinter->do_stem_adjust.
+	(ah_hinter_load_glyph): Set hinter->do_stem_adjust.
+
+	* src/pshinter/pshalgo3.h (PSH3_GlyphRec): Add `do_stem_adjust'.
+	* src/pshinter/pshalgo3.c (psh3_hint_align): Use `do_stem_adjust'.
+	(ps3_hints_apply): Handle FT_RENDER_MODE_LIGHT.
+
+	* include/freetype/freetype.h (FT_Render_Mode): Add
+	FT_RENDER_MODE_LIGHT.
+
+	* src/truetype/ttgload.c: Fixing the TrueType loader to handle
+	invalid composites correctly by limiting the recursion depth.
+	(TT_MAX_COMPOSITE_RECURSE): New macro.
+	(load_truetype_glyph): Add argument `recurse_count'.
+	Load a composite only if the numbers of contours is -1, emit error
+	otherwise.
+	(TT_Load_Glyph): Updated.
+
+2003-01-08  David Turner  <david@freetype.org>
+
+	* Jamrules, Jamfile, Jamfile.in, src/*/Jamfile: Small changes to
+	support the compilation of FreeType 2 as part of larger projects
+	with their own configuration options (only with Jam).
+
+2003-01-07  David Turner  <david@freetype.org>
+
+	* src/base/ftstroker.c: Probably the last bug-fixes to the stroker;
+	the API is likely to change, however.
+	(ft_stroke_border_close): Don't record empty paths.
+	(ft_stroke_border_get_counts): Increase `num_points' also in for loop.
+	(ft_stroke_border_export): Don't increase `write' twice in for loops.
+	(ft_stroker_outside): Handle `phi' together with `theta'.
+	(FT_Stroker_ParseOutline): New function.
+
+	* src/base/fttrigon.c (FT_Angle_Diff): Fixing function: It returned
+	invalid values for large negative angle differences (resulting in
+	incorrect stroker computations, among other things).
+
+	* src/cache/ftccache.c (ftc_node_hash_unlink): Removing incorrect
+	assertion, and changing code to avoid hash table size contraction.
+
+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: Adding
+	`ftstroker' to default build, as optional component.
+
+2002-12-26  David Turner  <david@freetype.org>
+
+	* src/gzip/adler32.c, src/gzip/infblock.c, src/gzip/inflate.c,
+	src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
+	src/gzip/zutil.h: Updates to allow compilation without compiler
+	warnings with LCC-Win32.
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 4.
+	* builds/unix/configure.ac (version_info): Increased to 9:3:3.
+	* builds/unix/configure: Regenerated.
+	* docs/VERSION.DLL: Updated.
+
+2002-12-23  Anthony Fok  <anthony@thizlinux.com>
+
+	* builds/unix/configure.ac, builds/unix/unix-cc.in (LINK_LIBRARY),
+	builds/unix/unix-def.in (SYSTEM_ZLIB): Small fix to configure
+	sub-system on Unix to allow other programs to correctly link with
+	zlib when needed.
+
+2002-12-19  David Turner  <david@freetype.org>
+
+	* include/freetype/internal/sfnt.h (SFNT_Load_Table_Func): New
+	function pointer.
+
+	* include/freetype/tttables.h (FT_Load_Sfnt_Table): New function.
+	* src/base/ftobjs.c: Implement it.
+
+	* src/sfnt/sfdriver.c (sfnt_get_interface): Handle `load_sfnt'
+	module request.
+
+2002-12-17  David Turner  <david@freetype.org>
+
+	* src/base/ftobjs.c (find_unicode_charmap): Added some comments to
+	better explain what's happening there.
+	(open_face): Included Graham Asher's fix to prevent faces without
+	Unicode charmaps from loading.
+
+	* src/winfonts/winfnt.c: Included George Williams's fix to support
+	version 2 fonts correctly.
+	(winfnt_header_fields): Updated.
+	(fnt_font_load): Handle version 2 fonts.
+	(FNT_Load_Glyph): Updated.
+
+2002-12-16  David Turner  <david@freetype.org>
+
+	* docs/VERSION.DLL: Updating document to better explain the
+	differences between the three version numbers being used on Unix, as
+	well as providing an autoconf fragment provided by Lars Clausen.
+
+	* src/smooth/ftgrays.c (gray_render_conic): Fixed small bug that
+	prevented Bézier arcs with negative vertical coordinates to be
+	rendered appropriately.
+
+2002-12-02  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* src/base/ftobjs.c: Modified the logic to get Unicode charmaps.
+	Now it loads UCS-4 charmaps when there is one.
+	(find_unicode_charmap): New function.
+	(open_face): Refer to the above one.
+	(FT_Select_Charmap): Idem.
+
+2002-11-29  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* include/freetype/ftgzip.h: Correct the name of the controlling
+	macro (was __FTXF86_H__ ...).
+
+2002-11-27  Vincent Caron  <v.caron@zerodeux.net>
+
+	* builds/unix/unix-def.in, builds/unix/freetype-config.in,
+	builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c
+	[FT_CONFIG_OPTION_SYSTEM_ZLIB]: Adding support for system zlib
+	installations if available on the target platform (Unix only).
+
+2002-11-23  David Turner  <david@freetype.org>
+
+	* src/cff/cffload.c (cff_charset_load, cff_encoding_load): Modified
+	charset loader to accept pre-defined charsets, even when the font
+	contains fewer glyphs.  Also enforced more checks to ensure that we
+	never overflow the character codes array in the encoding.
+
+2002-11-22  Antoine Leca  <Antoine-Freetype@Leca-Marti.org>
+
+	* include/freetype/ttnameid.h: Updated to latest OpenType
+	specification.
+
+2002-11-18  David Turner  <david@freetype.org>
+
+
+	* Version 2.1.3 released.
+	=========================
+
+
+2002-11-07  David Turner  <david@freetype.org>
+
+	* src/cache/ftcsbits.c (ftc_sbit_node_load): Fixed a small bug that
+	caused problems with embedded bitmaps.
+
+	* src/otlayout/otlayout.h, src/otlyaout/otlconf.h,
+	src/otlayout/otlgsub.c, src/otlayout/otlgsub.h,
+	src/otlayout/otlparse.c, src/otlayout/otlparse.h,
+	src/otlayout/otlutils.h: Updating the OpenType Layout code, adding
+	support for the first GSUB lookups.  Nothing that really compiles
+	for now though.
+
+	* src/autohint/ahhint.c (ah_align_serif_edge): Disabled serif stem
+	width quantization.  It produces slightly better shapes though this
+	is not distinguishable with many fonts.
+	Remove other dead code.
+
+	* src/Jamfile, src/*/Jamfile: Simplified.
+	Use $(FT2_SRC_DIR).
+
+2002-11-06  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h (FT_LOAD_TARGET_LIGHT): New macro.
+	(FT_LOAD_TARGET, FT_LOAD_TARGET_MODE): Use `& 15' instead of `& 7'.
+
+2002-11-05  David Turner  <david@freetype.org>
+
+	* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: Added
+	support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
+	the use of system-wide zlib.
+
+	Note that this macro, as well as
+	TT_CONFIG_OPTION_BYTECODE_INTERPRETER, is not #undef-ed anymore.
+	This allows the build system to define them depending on the
+	configuration (typically by adding -D flags at compile time).
+
+	* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Removed compiler
+	warnings in optimized mode relative to the `volatile' local
+	variables.  This was not a compiler bug after all, but the fact that
+	a pointer to a volatile variable is not the same as a volatile
+	pointer to a variable :-)
+
+	The fix was to change
+	  `volatile FT_Byte* p'
+	into
+	  `FT_Byte* volatile p'.
+
+	* src/pfr/pfrload.c (pfr_phy_font_load), src/pfr/pfrdrivr.c
+	(pfr_get_metrics), src/gzip/inftrees.c: Removed compiler warnings in
+	optimized modes.
+
+	* src/gzip/*.[hc]: Modified our zlib copy in order to prevent
+	exporting any zlib function names outside of the component.  This
+	prevents linking problems on some platforms, when applications want
+	to link FreeType _and_ zlib together.
+
+2002-11-05  Juliusz  <jch@pps.jussieu.fr>
+
+	* src/psaux/psobjs.c (ps_table_add): Modified increment loop in
+	order to implement exponential behaviour.
+
+2002-11-01  David Turner  <david@freetype.org>
+
+	Added PFR-specific public API.  Fixed the kerning retrieval routine
+	(it returned invalid values when the outline and metrics resolution
+	differ).
+
+	* include/freetype/ftpfr.h, include/freetype/internal/pfr.h: New
+	files.
+
+	* include/freetype/internal/internal.h (FT_INTERNAL_PFR_H): New
+	macro for pfr.h.
+
+	* src/base/ftpfr.c: New file.
+	* src/base/Jamfile, src/base/descrip.mms: Updated.
+
+	* src/pfr/pfrdrivr.c: Include FT_INTERNAL_PFR_H.
+	(pfr_get_kerning, pfr_get_advance, pfr_get_metrics): New functions.
+	(pfr_service_rec): New format interface.
+	(pfr_driver_class): Use `pfr_service_rec'.
+	Replace `pfr_face_get_kerning' with `pfr_get_kerning'.
+	* src/pfr/pfrobjs.c: Remove dead code.
+
+	* src/base/ftobjs.c (ft_glyphslot_clear): Small internal fix to
+	better support bitmap-based font formats.
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix handling of
+	`scale'.
+	Fix arguments to `FT_Vector_From_Polar'.
+
+2002-10-31  David Turner  <david@freetype.org>
+
+	Add support for automatic handling of gzip-compressed PCF files.
+
+	* src/gzip/*: New files, taken from the zlib package (except
+	ftgzip.c).
+
+	* include/freetype/ftgzip.h, src/gzip/ftgzip.c: New files.
+	* include/freetype/config/ftheader.h (FT_GZIP_H): New macro for
+	`ftgzip.h'.
+
+	* src/pcf/pcfdriver.c: Include FT_GZIP_H and FT_ERRORS_H.
+	(PCF_Face_Init): If normal open fails, try to open gzip stream.
+	(PCF_Face_Done): Close gzip stream.
+
+	* include/freetype/internal/pcftypes.h (PCF_Public_FaceRec),
+	src/pcf/pcf.h (PCF_FaceRec): Add `gzip_stream' and `gzip_source'.
+

+
+2002-08-29  David Turner  <david@freetype.org>
+

+
+	* include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Add hint

+	* README, docs/CHANGES: Updating for the 2.1.3 release.
+
+2002-08-27  David Turner  <david@freetype.org>
+
+	* Massive re-formatting changes to many, many source files.  I don't
+	want to list them all here.  The operations performed were all
+	logical transformations of the sources:
+
+	- trying to convert all enums and constants to CAPITALIZED_STYLE,
+	  #with define definitions like
+
+	    #define my_old_constants   MY_NEW_CONSTANT
+
+	- big, big update of the documentation comments
+
+	* include/freetype/freetype.h, src/base/ftobjs.c,
+	src/smooth/ftsmooth.c, include/freetype/ftimage.h: Adding support
+	for LCD-optimized rendering though the new constants/enums:
+
+	  FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
+	  FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V
+
+	This is still work in progress, don't expect everything to work
+	correctly though most of the features have been implemented.
+
+	* Adding new FT_LOAD_XXX flags, used to specify both hinting and
+	rendering targets:
+
+	  FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
+	  FT_LOAD_TARGET_MONO   :: monochrome bitmaps
+	  FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated
+	                           hinting & rendering
+	  FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated
+	                           hinting & rendering
+
+	Note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
+	behaviour of the font engine is _unchanged_.
+
+	* include/freetype/ftimage.h
+	(FT_Outline_{Move,Line,Conic,Cubic}To_Func): Renamed to...
+	(FT_Outline_{Move,Line,Conic,Cubic}ToFunc): This.

+	have been updated accordingly.

+2002-08-23  Graham Asher  <graham.asher@btinternet.com>
+
+	* src/cff/cffgload.c (cff_operator_seac)
+	[FT_CONFIG_OPTION_INCREMENTAL]: Incremental fonts (actually not
+	incremental in the case of CFF but just using callbacks to get glyph
+	recipes) pass the character code, not the glyph index, to the
+	get_glyph_data function; they have no valid charset table.
+
+	* src/cff/cffload.c (cff_font_load): Removed special cases for
+	FT_CONFIG_OPTION_INCREMENTAL, which are no longer necessary; CFF
+	fonts provided via the incremental interface now have to conform
+	more closely to the CFF font format.

+
+2002-08-21  David Turner  <david@freetype.org>
+
+	The automatic and Postscript hinter now automatically detect

+
+	* src/type1/t1load.c (T1_Open_Face): Tolerate a face with no

+	typically not provide any charstrings at load time, so this is
+	essential if they are to work.
+
+2002-08-01  Graham Asher  <graham.asher@btinternet.com>
+
+	Modified incremental loading interface to be closer to David's
+	preferences.  The header freetype.h is not now affected, the
+	interface is specified via an FT_Parameter, the pointer to the
+	interface is hidden in an internal part of the face record, and all
+	the definitions are in ftincrem.h.
+
+	* include/freetype/freetype.h [FT_CONFIG_OPTION_INCREMENTAL]:

+
+2002-07-18  Graham Asher  <graham.asher@btinternet.com>
+
+	Added types and structures to support incremental typeface loading.
+	The FT_Incremental_Interface structure, defined in freetype.h, is
+	designed to be passed to FT_Open_Face to provide callback functions
+	to obtain glyph recipes and metrics, for fonts like those passed
+	from PostScript that do not necessarily provide all, or any, glyph
+	information, when first opened.
+
+	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):

+	for the CID driver.
+

+
+2005-05-28  David Turner  <david@freetype.org>
+
+	* docs/CHANGES: Updating file for next release (2.1.1).
+
+	* src/bdf/bdflib.c: Removing compiler warnings.
+
+	* include/freetype/ftxf86.h, src/base/ftxf86.c: New files.
+	They provide a new API (FT_Get_X11_Font_Format) to retrieve an
+	X11-compatible string describing the font format of a given face.
+	This was put in a new optional base source file, corresponding to a
+	new public header (named FT_XFREE86_H since this function should
+	only be used within the XFree86 font server IMO).
+
+	* include/freetype/config/ftheader.h (FT_XFREE86_H): New macro (not
+	documented yet).
+
+	* src/base/fttype1.c: New file, providing two new API functions
+	(FT_Get_PS_Font_Info and FT_Has_PS_Glyph_Names).
+	* include/freetype/t1tables.h: Updated.
+
+	* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
+	Updating build control files for the new files `ftxf86.c' and
+	`fttype1.c' in src/base.
+
+	* src/pshinter/pshglob.c (psh_blues_scale_zones): Fixed a bug that
+	prevented family blue zones substitution from happening correctly.
+
+	* include/freetype/ftbdf.h FT_Get_BDF_Charset_ID): Adding
+	documentation comment.
+
+2002-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT
+	but FT_STREAM_READ.
+	Declare `stream' variable.
+
+	* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math
+	with calls to `FT_MulDiv'.
+
+2002-05-28  David Turner  <david@freetype.org>
+
+	Fixing the SFNT name table loader to support various buggy fonts.
+	It now ignores empty name entries, entries with invalid pointer
+	Offsets and certain fonts containing tables with broken
+	`storageOffset' fields.
+
+	Name strings are now loaded on demand, which reduces the memory
+	requirements for a given FT_Face tremendously (for example, the name
+	table of Arial.ttf is about 10Kb and contains 70 names).
+
+	This is a temporary fix.  The whole name table loader and interface
+	will be rewritten in a much more cleanly way shortly, once CSEH have
+	been introduced in the sources.
+
+	* include/freetype/internal/tttypes.h (TT_NameEntryRec): Change
+	type of `stringOffset' to FT_ULong.
+	(TT_NameTableRec): Change type of `numNameRecords' and
+	`storageOffset' to FT_UInt.
+	Replace `storage' with `stream'.
+	* src/base/ftnames.c (FT_Get_Sfnt_Name): Load name on demand.
+	* src/sfnt/sfdriver.c (get_sfnt_postscript_name): Ditto.
+	Make code more robust.
+	* src/sfnt/sfobjs.c (TT_NameEntry_ConvertFunc): New typedef.
+	(tt_face_get_name): Use it.
+	Make code more robust.
+	* src/sfnt/ttload.c (TT_Load_Names): Use `static' for arrays.
+	Handle invalid `storageOffset' data better.
+	Set length fields to zero for invalid or ignored data.
+	Remove code within FT_DEBUG_LEVEL_TRACE.
+	(TT_Free_Names): Updated.
+
+2002-05-24  Tim Mooney  <enchanter@users.sourceforge.net>
+
+	* builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and
+	FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be
+	rebuilt from sources.  Set macro serial to 1, and use third argument
+	to AC_DEFINE for our two custom symbols, so ftconfig.in could one day
+	be rebuilt with autoheader (not recommended now, ftconfig.in is a
+	custom source file)
+
+2002-05-22  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftheader.h (FT_BEZIER_H): Removed.

+	for undocumented, obsolete opcode 15.
+
+2002-05-21  David Turner  <david@freetype.org>
+
+	* src/bdf/bdflib.c: Removed compiler warning, and changed all tables
+	to the `static const' storage specifier (instead of simply
+	`static').
+
+	* src/type42/t42drivr.c (hexval): Use more efficient code.
+	Removing compiler warnings.
+	* src/bdf/bdfdrivr.c: Removing compiler warnings.
+
+	* include/freetype/internal/ftbdf.h, src/base/ftbdf.c,
+	src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk
+	(FT_Get_BDF_Charset_ID): New API to retrieve BDF-specific strings
+	from a face.  This is much cleaner than accessing the internal types
+	`BDF_Public_Face' defined in FT_INTERNAL_BDF_TYPES_H.

+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Finally fixing the last
+	bug that prevented FreeType 2.x and FreeType 1.x to produce
+	bit-by-bit identical monochrome glyph bitmaps with native TrueType
+	hinting.  The culprit was a single-bit flag that wasn't set
+	correctly by the TrueType glyph loader.

+	This is generic implementation of dynamic hash tables using a linear

+	* include/freetype/internal/internal.h (FT_INTERNAL_HASH_H,
+	FT_INTERNAL_OBJECT_H): New macros.

+	is very likely that this file will disappear or be renamed in the
+	future.
+
+	* include/freetype/internal/ftobject.h, include/freetype/ftsysmem.h:
+	Adding comments to better explain the object sub-system as well as

+
+	Added the new configuration file `ftstdlib.h' used to define

+
+	This eases the porting of FreeType 2 to environments like

+	from the engine's sources where they are not needed.

+
+	* src/psaux/t1cmap.h, src/psaux/t1cmap.c, src/type1/t1cmap.h,
+	src/type1/t1cmap.c: Updating and moving the Type 1 FT_CMap support
+	from `src/type1' to `src/psaux' since it is going to be shared by

+	src/psaux/rules.mk, include/freetype/internal/psaux.h: Added support

+	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fixed a small bug that
+	caused the library to crash with Electric Fence when memory
+	debugging is used.
+
+	* Renaming stream macros.  Examples:
+

+	  FILE_Read    => FT_STREAM_READ

+	1.4.2.
+	Apply a small patch for AIX to make shared libraries work (this
+	patch is already in the CVS version of libtool).
+
+	* builds/unix/config.sub, builds/unix/config.guess: Updated to
+	recent versions.
+
+	* builds/unix/configure.ac: Fix typo
+	(AC_CONFIG_FILE->AC_CONFIG_FILES).
+
+	* builds/unix/configure: Regenerated.
+
+2002-02-28  David Turner  <david@freetype.org>
+
+	* include/freetype/ftconfig.h: Changed `FT_LOCAL xxxx' to
+	`FT_LOCAL( xxxx )' everywhere in the source.  The same goes for
+	`FT_LOCAL_DEF xxxx' which is translated to `FT_LOCAL_DEF( xxxxx )'.
+
+	* include/freetype/freetype.h (FREETYPE_MINOR, FREETYPE_PATCH):
+	Changing version to 2.1.0 to indicate an unstable branch.
+	Added the declarations of FT_Get_First_Char and FT_Get_Next_Char.
+
+	* src/base/ftobjs.c: Implement FT_Get_First_Char and
+	FT_Get_Next_Char.
+
+	* include/freetype/t1tables.h: Renaming structure types.  This
+
+	  typedef  T1_Struct_
+	  {
+	  } T1_Struct;
+
+	becomes
+
+	  typedef  PS_StructRec_
+	  {
+	  } PS_StructRec, *PS_Struct;
+
+	  typedef PS_StructRec  T1_Struct;  /* backwards-compatibility */
+
+	Hence, we increase the coherency of the source code by effectively
+	using the `Rec' prefix for structure types.
+
+2002-02-27  David Turner  <david@freetype.org>
+
+	* src/sfnt/ttload.c (TT_Load_Names): Simplifying and securing the
+	names table loader.  Invalid individual name entries are now handled
+	correctly.  This allows the loading of very buggy fonts like
+	`foxjump.ttf' without allocating tons of memory and causing crashes.
+
+	* src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: Adding (still
+	experimental) code for OpenType Layout tables validation and
+	parsing.
+
+	* src/type1/t1cmap.h, src/type1/t1cmap.c: Adding (still
+	experimental) code for Type 1 charmap processing.
+
+	* src/sfnt/ttcmap0.c: New file.  It contains a new, still
+	experimental SFNT charmap processing support.
+
+	* include/freetype/internal/ftobjs.h: Adding validation support as
+	well as internal charmap object definitions (FT_CMap != FT_CharMap).
+
+2002-02-24  David Turner  <david@freetype.org>
+
+	* Renaming stream functions to the FT_<Subject>_<Action> scheme:
+
+	  FT_Seek_Stream    => FT_Stream_Seek
+	  FT_Skip_Stream    => FT_Stream_Skip
+	  FT_Read_Stream    => FT_Stream_Read
+	  FT_Read_Stream_At => FT_Stream_Read_At
+	  FT_Access_Frame   => FT_Stream_Enter_Frame
+	  FT_Forget_Frame   => FT_Stream_Exit_Frame
+	  FT_Extract_Frame  => FT_Stream_Extract_Frame
+	  FT_Release_Frame  => FT_Stream_Release_Frame
+	  FT_Get_XXXX       => FT_Stream_Get_XXXX
+	  FT_Read_XXXX      => FT_Stream_Read_XXXX
+
+	  FT_New_Stream( filename, stream ) =>
+	    FT_Stream_Open( stream, filename )
+
+	    (The function doesn't create the FT_Stream structure, it simply
+	    initializes it for reading.)
+
+	  FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>
+	    FT_Stream_Open_Memory( stream, const FT_Byte* base, size )
+
+	  FT_Done_Stream  => FT_Stream_Close
+	  FT_Stream_IO    => FT_Stream_IOFunc
+	  FT_Stream_Close => FT_Stream_CloseFunc
+
+	  ft_close_stream => ft_ansi_stream_close (in base/ftsystem.c only)
+	  ft_io_stream    => ft_ansi_stream_io    (in base/ftsystem.c only)
+
+	* src/base/ftutil.c: New file.  Contains all memory and list
+	management code (previously in `ftobjs.c' and `ftlist.c',
+	respectively).
+
+	* include/freetype/internal/ftobjs.h: Moving all code related to
+	glyph loaders to ...
+	* include/freetype/internal/ftgloadr.h: This new file.
+	`FT_GlyphLoader' is now a pointer to the structure
+	`FT_GlyphLoaderRec'.
+	(ft_glyph_own_bitmap): Renamed to ...
+	(FT_GLYPH_OWN_BITMAP): This.
+	* src/base/ftobjs.c: Moving all code related to glyph loaders
+	to ...
+	* src/base/ftgloadr.c: This new file.

+
+2002-02-21  David Turner  <david@freetype.org>
+
+	Modified the debug sub-system initialization.  Trace levels can now
+	be specified within the `FT2_DEBUG' environment variable.  See the
+	comments within `ftdebug.c' for more details.
+
+	* src/base/ftdebug.c: (FT_SetTraceLevel): Removed.
+	(ft_debug_init): New function.
+	(ft_debug_dummy): Removed.
+	Updated to changes in ftdebug.h
+
+	* include/freetype/internal/ftdebug.h: Always define

+	(FT_Assert): Renamed to ...
+	(FT_ASSERT): This.
+	Some stuff from ftdebug.h has been moved to ...
+
+	* include/freetype/internal/fttrace.h: New file, to define the trace
+	levels used for debugging.  It is used both to define enums and
+	toggle names for FT2_DEBUG.
+
+	* include/freetype/internal/internal.h: Updated.
+
+	* src/base/ftobjs.c, src/base/ftstream.c: Updated.
+
+	* include/freetype/internal/ftextend.h, src/base/ftextend.c:
+	Removed.  Both files are now completely obsolete.
+	* src/base/Jamfile, src/base/rules.mk: Updated.
+
+	* include/freetype/fterrors.h: Adding `#undef FT_ERR_CAT' and

+
+2006-05-03  David Turner  <david@freetype.org>
+
+	Allow compilation again with C++ compilers.
+
+	* include/freetype/internal/ftmemory.h (FT_ASSIGNP,
+	FT_ASSIGNP_INNER): New macros which do the actual assignment, and
+	which exist in two variants (for C and C++).
+	Update callers accordingly.
+
+2006-05-03  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.
+
+2006-05-02  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftmemory.h: s/new/newsz/ (for C++).
+	(FT_ALLOC): Remove redundant redefinition.
+
+	* builds/compiler/gcc-dev.mk (CFLAGS) [g++]: Don't use
+	`-Wstrict-prototypes'.
+
+	* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.
+
+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:
+	Remove `extern'.
+
+2006-05-02  David Turner  <david@freetype.org>
+
+	Update the memory management functions and macros to safely deal
+	with array size buffer overflows.  This corresponds to attempts to
+	allocate arrays that are too large.  For an example, consider the
+	following code:
+
+	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
+	  count ); for ( nn = 0; nn < count; nn++ )
+	    array[nn] = read_item_from_file();
+
+	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
+	multiplication overflows, and the array allocated os smaller than
+	the data read from the file.  In this case, the heap will be
+	trashed, and this can be used as a denial-of-service attack, or make
+	the engine crash later.
+
+	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
+	count is no larger than `FT_INT_MAX/item_size', otherwise a new
+	error code `FT_Err_Array_Too_Large' will be returned.
+
+	Note that the memory debugger now works again when FT_DEBUG_MEMORY
+	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding
+	code is now the default.
+
+
+	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
+	Don't use `extern'.
+
+	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
+	code.
+
+	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
+	[FT_DEBUG_MEMORY]: New macro.
+	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.

+	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,
+	FT_MEM_FREE): Redefine.
+	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,
+	FT_MEM_QRENEW_ARRAY): Redefine.
+	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,
+	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
+	appropriate.
+	(FT_MEM_SET_ERROR): Slightly redefine.
+
+
+	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)
+	[FT_DEBUG_MEMORY]: New global variables, replacing...
+	(FT_MemTable_Rec) [FT_DEBUG_MEMORY]: Remove `filename' and
+	`line_no'.  Update all callers.
+	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer
+	overflow.
+	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,
+	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.
+
+	* src/base/ftmac.c (read_lwfn): Catch integer overflow.
+	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.
+	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.
+	(ft_mem_alloc, ft_mem_realloc, ft_mem_qrealloc): Rewrite.
+
+
+	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,
+	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
+	place where the frames were entered, extracted, exited or released
+	in the memory debugger.
+
+	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
+	Call ft_mem_free.
+	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
+	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.
+
+2006-04-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos
+	initialization, remove extra cast to copy to pfb_lenpos.  This fixes
+	parsing of PFB fonts with MacOS resource fork (bug introduced
+	2003-09-11).  Patch provided by Huib-Jan Imbens <ft@imbens.nl>.
+
+2006-04-29  Werner Lemberg  <wl@gnu.org>

+	C library functions.  Update all users accordingly (and catch some
+	other places where the C library function was used instead of the
+	wrapper functions).
+
+	* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.
+	* src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't

+	compatibility code.
+

+
+	* include/freetype/ftoutln.h (enum FT_Orientation): New value

+	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
+	ft_contour_enclosed, ft_outline_get_orientation): Another version of

+	one in that each part (contour not enclosed in another contour) of the
+	outline is checked for orientation.
+	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and

+
+	* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,

+
+	* src/truetype/ttpload.c (tt_face_load_hdmx,

+	actually used.
+
+2006-02-21  David Turner  <david@freetype.org>
+
+	Add a new API named FT_Get_TrueType_Engine_Type to determine whether

+	interpreter.
+
+	The FT_Get_Module_Flags API was removed consequently.
+

+	embedded bitmaps from being correctly listed and used.
+
+
+	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
+	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because
+	libXfont is directly accessing the HMTX data, unfortunately.
+	Fix some compiler warnings.
+	(tt_face_get_metrics): Ditto.
+
+
+	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
+	character advances.
+
+2006-02-20  David Turner  <david@freetype.org>
+
+	Support binary compatibility with the X.Org server's Xfont library.

+
+2006-02-17  David Turner  <david@freetype.org>
+
+	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported

+
+	* include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE,

+	(finally!)
+
+
+	For most OpenType tables, `tt_face_load_xxxx' simply loads the table
+	and `face->root' is set later in `sfnt_load_face'.  Here, we try to

+
+	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
+	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
+	then exit.  Error handling or setting face->root is done later in
+	`sfnt_load_face'.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
+	Mac bitmap-only fonts are not scalable.
+	Check that `face->header.Units_Per_EM' is not zero.
+	(LOAD_, LOADM_): Emit pretty trace messages.

+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	Clean up the SFNT_Interface.  In this pass, we want to treat the
+	font directory (offset table and table directory) as a normal table
+	like the others.  This also means that TTCs are no longer recognized
+	there but in `init_face'.
+
+	* include/freetype/internal/sfnt.h (SFNT_Interface),
+	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
+	combined and renamed to `load_font_dir'.
+
+	* src/sfnt/ttload.h, src/sfnt/ttload.c:
+	s/sfnt_dir_check/check_table_dir/.
+	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.

+	and renamed to `tt_face_load_font_dir'.
+
+	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.
+
+2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>
+
+	Clean up the SFNT_Interface.  Table loading functions are now named
+	after the tables' tags; `hdmx' is TrueType-specific and thus the
+	code is moved to the truetype module; `get_metrics' is moved here
+	from the truetype module so that the code can be shared with the cff
+	module.
+
+	This pass involves no real changes.  That is, the code is moved
+	verbatim mostly.  The only exception is the return value of

+	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.
+
+	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related
+	tables' loading and parsing code is moved to here.
+	Move `tt_face_get_metrics' here from the truetype module.  The
+	return value is changed from `void' to `FT_Error'.
+
+	* include/freetype/internal/fttrace.h: New trace: ttmtx.
+
+	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
+	parsing code is moved here.
+	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.
+	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

+
+	Implement new, simplified module selection.  With GNU make it is now
+	sufficient to modify a single file, `modules.cfg', to control the
+	inclusion of modules and base extension files.
+
+	This change also fixes the creation of ftmodule.h; it now depends on
+	`modules.cfg' and thus is rebuilt only if necessary.
+
+	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
+	default location.
+
+	* modules.cfg: New file.
+
+	* builds/freetype.mk: Don't include `modules.mk'.
+	Include all `rules.mk' files as specified in `modules.cfg'.

+	(make_module_list, clean_module_list): Replace targets
+	with...
+	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
+	variables.  Reason for the change is that it is not possible to have
+	a phony prerequisite which is run only if the target file must be
+	rebuilt (phony prerequisites act like subroutines and are *always*
+	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
+	changed.
+	Update all callers.
+	($FTMODULE_H)): Rule to create `ftmodule.h', depending on
+	`modules.cfg'.
+
+	* builds/toplevel.mk: Rewrite and simplify module handling.
+	(MODULES_CFG, FTMODULE_H): New variables.
+	Include MODULES_CFG.
+	(MODULES): New variable to include all `module.mk' and `rules.mk'

+	(have_mk): Don't use `strip' function.
+	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
+	accordingly).
+
+	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.
+
+	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,

+
+	* src/autofit/afwarp.c: Add simple #ifdef to prevent compilation

+
+	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'
+	and `otvalid' from the list of modules that are linked statically

+
+	Note also that current Make-based build system still compiles the
+	modules though.
+
+	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro
+	which controls the definitions of the memory management functions to
+	avoid warnings with recent versions of GCC.  This macro is only here
+	to be disabled, in case we detect problems with the new scheme.
+
+	NOTE: Disable macro to use the memory debugger -- this will be fixed
+	      later!
+
+	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,
+	FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]:

+
+	* include/freetype/internal/ftobjs.h (FT_REQUEST_WIDTH,

+
+	* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
+	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
+	FT_Request_Metrics): New base functions to set the font metrics.  They
+	were part of FT_Select_Size/FT_Request_Size and are made independent
+	functions so that metrics are not set again and again.
+
+	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
+	only when driver's size_select/size_request is NULL.  That is, drivers

+	(FT_Match_Size): Round before matching.  This was what we did and it
+	does cause some problems without rounding.
+
+	* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
+	(tt_size_select): Set the font metrics.
+	s/index/strike_index/.
+	The scaled metrics are always preferred over strikes' metrics, even
+	when some strike is selected.  This is done because the strikes'

+	font to have no `head' table if tables `SING' and `META' are
+	present; this is to support `SING Glyphlet'.
+
+	`SING Glyphlet' is an extension to OpenType developed by Adobe
+	primarily to facilitate adding supplemental glyphs to an OpenType
+	font (with emphasis on, but not necessarily limited to, gaiji to a
+	CJK font).  A SING Glyphlet Font is an OpenType font that contains
+	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
+	`cmap', `BASE', and `GSUB' tables are present with the same format
+	and functionality as a regular OpenType font; there are no `name',
+	`head', `OS/2', and `post' tables; there are two new tables, `SING'
+	which contains details about the glyphlet, and `META' which contains
+	metadata.
+
+	Further information on the SING Glyphlet format can be found at:
+
+	  http://www.adobe.com/products/indesign/sing_gaiji.html
+
+	* include/freetype/tttags.h (TTAG_SING, TTAG_META): New macros for
+	the OpenType tables `SING' and `META'.  These two tables are used in
+	SING Glyphlet Format fonts.

+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline

+	rendering of buggy fonts.
+
+2005-08-20  Chia I Wu  <b90201047@ntu.edu.tw>
+
+	* src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of

+	Use loader->pp values instead of recalculation.
+	Use TT_Hint_Glyph.
+	No need to save/restore loader->stream before and after
+	TT_Vary_Get_Glyph_Deltas now.
+	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom
+	points.
+	(load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
+	Savannah bug #13107.
+	Forget glyph frame before calling TT_Process_Simple_Glyph.
+	Use TT_LOADER_SET_PP.
+	Scale all four phantom points.
+	Split off some functionality to ...
+	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
+	new functions.
+	(TT_Load_Glyph): Set various fields of `glyph' here, not in
+	load_truetype_glyph and compute_glyph_metrics.

+	* src/sfnt/ftbitmap.c, src/truetype/ttgload.c, src/sfnt/ttcmap.c:
+	Removing compiler warnings (Visual C++ /W4).
+
+
+	Implement a work-around for broken C preprocessor in Visual C++ (it
+	has been confirmed by the MS developers that it is indeed a bug
+	which won't be fixed in the very near future).
+
+	* Jamfile (FT2_COMPONENTS): Include otvalid (again).

+	FT_Outline_Get_CBox is called twice.
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
+	reasonable values when emboldening outline glyphs.  The theoretic
+	ones are unrealistic.
+
+2005-06-16  Chia I Wu  <b90201047@ntu.edu.tw>

+	  . As we use the glyph's cbox to calculate the top bearing now
+	    there is no need to adjust `top'.
+
+2005-06-15  Werner Lemberg  <wl@gnu.org>

+
+	Really fix Savannah bug #28678 (part 2).
+
+	Since we consider `sbw' for the horizontal direction only, we still have

+	writing direction.
+
+	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c

+
+2010-02-10  Ken Sharp  <ken.sharp@artifex.com>
+
+	Really fix Savannah bug #28678 (part 1).
+
+	After long discussion, we now consider the character width vector
+	(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
+	direction only.  For example, if you are using the horizontal
+	writing direction, you get the horizontal and vertical components of
+	the advance width for this direction.  Note that OpenType and CFF fonts
+	don't have such a vertical component; instead, the GPOS table can be
+	used to generate two-dimensional advance widths (but this isn't
+	handled by FreeType).

+
+2010-01-08  Ken Sharp  <ken.sharp@artifex.com>
+
+	Fix Savannah bug #28521.
+
+	Issue #28226 involved a work-around for a font which used the
+	`setcurrentpoint' operator in an invalid way; this operator is only
+	supposed to be used with the result of OtherSubrs, and the font used
+	it directly.  The supplied patch removed the block of code which
+	checked this usage entirely.
+
+	This turns out to be a Bad Thing.  If `setcurrentpoint' is being
+	used correctly it should reset the flex flag in the decoder.  If we
+	don't do this then the flag never gets reset and we omit any further
+	contours from the glyph (at least until we close the path or
+	similar).
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)

+
+	Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
+	This fixes Savannah bug #28226.
+
+	At least two wild PostScript files of unknown provenance contain
+	Type 1 fonts, apparently converted from TrueType fonts in earlier
+	PDF versions of the files, which use the `setcurrentpoint' operator
+	inappropriately.
+
+	FreeType currently throws an error in this case, but Ghostscript and
+	Adobe Distiller both accept the fonts and ignore the problem.  This
+	commit #ifdefs out the check so PostScript interpreters using
+	FreeType can render these files.
+
+	The specification says `setcurrentpoint' should only be used to set
+	the point after a `Subr' call, but these fonts use it to set the
+	initial point to (0,0).  Unnecessarily so, as they correctly use an
+	`hsbw' operation which implicitly sets the initial point.
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
+	<op_setcurrentpoint>: Comment out code.

+
+	[BDF] Modify hash API to take size_t value instead of void *.
+
+	The hash API in BDF driver is designed to be generic, it takes
+	void * typed data.  But BDF driver always gives an unsigned long
+	integer (the index to a property).  To reduce non-essential
+	casts from unsigned long to void* and from void* to unsigned
+	long, the hash API is changed to take size_t integer.
+	The issue of incompatible cast between unsigned long and void*
+	on LLP64 platform is reported by NightStrike from MinGW-Win64
+	project.  See
+	http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

+	(_bdf_set_default_spacing): Get the name length of the face by

+	(bdf_get_property): Get the property id by size_t variable to

+
+	Improve vertical metrics calculation (Savannah bug #27364).
+
+	The calculation of `vertBearingX' is not defined in the OTF font
+	spec so FreeType does a `best effort' attempt.  However, this value
+	is defined in the PDF and PostScript specs, and that algorithm is
+	better than the one FreeType currently uses:
+
+	  FreeType: Use the middle of the bounding box as the X coordinate
+	            of the vertical origin.
+
+	  Adobe PDF spec: Use the middle of the horizontal advance vector as
+	                  the X coordinate of the vertical origin.
+
+	FreeType's algorithm goes wrong if you have a really small glyph
+	(like the full-width, circle-like dot at the end of the sentence, as
+	used in CJK scripts) with large bearings.  With the FreeType
+	algorithm this dot gets centered on the baseline; with the PDF
+	algorithm it gets the correct location (in the top right).  Note
+	that this is a serious issue, it's like printing the dot at the end
+	of a Roman sentence at the center of the textline instead of on the
+	baseline like it should. So i believe the PDF spec's algorithm
+	should be used in FreeType as well.
+
+	The `vertBearingY' value for such small glyphs is also very strange
+	if no `vmtx' information is present, since the height of the bbox is
+	not representable for the height of the glyph visually (the
+	whitespace up to the baseline is part of the glyph).  The fix also
+	includes some code for a better estimate of `vertBearingY'.
+
+	* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
+	is now calculated as described by the Adobe PDF Spec.  Estimate for
+	`vertBearingY' now works better for small glyphs completely above or
+	below the baseline into account.
+
+	* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
+	calculated as described by the Adobe PDF Spec.  Vertical metrics
+	information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
+	was not defined.
+
+	* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
+	now calculated as described by the Adobe PDF Spec.

+
+	Use 16.16 format while parsing Type 1 charstrings.
+	This fixes Savannah bug #26867.
+
+	Previously, only integers have been used which can lead to serious
+	rounding errors.
+
+	However, fractional values are only used internally; after the
+	charstrings (of either Type 1 or 2) have been processed, the
+	resulting coordinates get rounded to integers currently -- before
+	applying scaling.  This should be fixed; at the same time a new load
+	flag should be introduced, to be used in combination with
+	FT_LOAD_NO_SCALE, which indicates that font units are returned in
+	16.16 format.  Similarly, the incremental interface should be
+	extended to allow fractional values for metrics.

+
+	Fix B/W rasterization of subglyphs with different drop-out modes.
+
+	Normally, the SCANMODE instruction (if present) to set the drop-out
+	mode in a TrueType font is located in the `prep' table only and thus
+	valid for all glyphs.  However, there are fonts like `pala.ttf'
+	which additionally contain this instruction in the hinting code of
+	some glyphs (but not all).  As a result it can happen that a
+	composite glyph needs multiple drop-out modes for its subglyphs
+	since the rendering state gets reset for each subglyph.
+
+	FreeType collects the hinted outlines from all subglyphs, then it
+	sends the data to the rasterizer.  It also sends the drop-out mode
+	-- after hinting has been applied -- and here is the error: It sends
+	the drop-out mode of the last subglyph only; drop-out modes of all
+	other subglyphs are lost.
+
+	This patch fixes the problem; it adds a second, alternative
+	mechanism to pass the drop-out mode: For each contour, the
+	rasterizer now checks the first `tags' array element.  If bit 2 is
+	set, bits 5-7 contain the contour's drop-out mode, overriding the
+	global drop-out mode.
+
+	* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
+
+	* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

+	Use bits 3-5 instead of 0-2.
+	(New_Profile): Set the drop-out mode in the profile's `flags' field.
+	(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if

+
+	Improve scan conversion rules 4 and 6.
+
+	Two new constraints are introduced to better identify a `stub' -- a
+	concept which is only vaguely described in the OpenType
+	specification.  The old code was too rigorous and suppressed more
+	pixel than it should.
+
+	  . The intersection of the two profiles with the scanline is less
+	    than a half pixel.  Code related to this was already present in
+	    the sources but has been commented out.
+
+	  . The endpoint of the original contour forming a profile has a
+	    distance (`overshoot') less than half a pixel to the scanline.
+
+	Note that the two additional conditions fix almost all differences
+	to the Windows rasterizer, but some problematic cases remain.
+
+	* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
+	macros for the `flags' field in the `TProfile' structure.
+	(IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
+	(New_Profile, End_Profile): Pass overshoot flag as an argument and
+	set it accordingly.
+	Update callers.
+	(Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
+	constraints.

+
+	Increase precision for B/W rasterizer.

+	example, glyph `xi' in verdana.ttf at 13 ppem.  Testing with ftbench
+	on my GNU/Linux box I don't see a performance degradation.

+
+	* src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
+
+2009-03-09  Alexey Kryukov  <anagnost@yandex.ru>
+
+	Fix handling of EBDT formats 8 and 9 (part 2).
+
+	This patch fixes the following problems in ttsbit0.c:
+
+	. Bitmaps for compound glyphs were never allocated.
+
+	. `SBitDecoder' refused to load metrics if some other metrics have
+	  already been loaded.  This condition certainly makes no sense for
+	  recursive calls, so I've just disabled it.  Another possibility
+	  would be resetting `decoder->metrics_loaded' to false before
+	  loading each composite component.  However, we must restore the
+	  original metrics after finishing the recursion; otherwise we can
+	  get a misaligned glyph.
+
+	. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
+	  causing some glyph components to be shifted too far to the right
+	  (especially noticeable for small sizes).
+
+	Note that support for grayscale bitmaps (not necessarily compound) is
+	completely broken in ttsbit0.c.
+
+	* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
+	(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
+	of `h == height'.
+	(tt_sbit_decoder_load_compound): Reset metrics after loading
+	components.
+	Allocate bitmap.
+

+
+	FT_USE_MODULE declares things as:
+
+	  extern const FT_Module_Class
+
+	(or similar for C++).  However, the actual types of the variables
+	being declared are often different, e.g., FT_Driver_ClassRec or
+	FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)
+
+	This works with most C compilers (since those structs begin with an
+	FT_Module_Class struct), but technically it's undefined behavior.
+
+	To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
+	paragraph 2:
+
+	  All declarations that refer to the same object or function shall
+	  have compatible type; otherwise, the behavior is undefined.
+
+	(And they are not compatible types.)
+
+	Most C compilers don't reject (or even detect!) code which has this
+	issue, but the GCC LTO development branch compiler does.  (It
+	outputs the types of the objects while generating .o files, along
+	with a bunch of other information, then compares them when doing the
+	final link-time code generation pass.)

+
+	Generalize the concept of `tricky' fonts by introducing
+	FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
+	engine is necessary for correct rendering.
+
+	At the same time, slightly modify the behaviour of tricky fonts:
+	FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
+	of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
+	FT_LOAD_NO_AUTOHINT must be used.
+
+	Finally, tricky TrueType fonts always use the bytecode interpreter
+	even if the patented code is used.

+2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/rules.mk: Add conditional source to BASE_SRC, for `make
+	multi' on Mac OS X.  If the macro $(ftmac_c) is defined,
+	$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC.  In a normal build, the

+
+2008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/ftconfig.in: Duplicate the cpp computation of

+
+	* builds/unix/configure.raw: Add the checks to compare the cpp

+	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
+	results.

+
+2008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or

+	* include/freetype/ftcache.h: Document it.
+
+
+	Make FT_MulFix an inlined function.  This is done to speed up
+	FreeType a little (on x86 3% when loading+hinting, 10% when

+
+	Use of assembler code can now be controlled with
+	FT_CONFIG_OPTION_NO_ASSEMBLER.
+
+	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in

+
+	* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and

+
+
+	Add a new header named FT_ADVANCES_H declaring some new APIs to
+	extract the advances of one or more glyphs without necessarily
+	loading their outlines.  Also provide `fast loaders' for the
+	TrueType, Type1, and CFF font drivers (more to come later).
+
+	* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
+
+	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
+	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.

+
+
+	Add checks for minimum version of the `autotools' stuff.
+

+
+2008-08-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_encoding): Protect against infinite

+
+2008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
+	even if passed library or arguments are invalid.  This fixes a bug
+	that an uninitialized stream is freed when an invalid library handle
+	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
+	freetype-devel.
+	(FT_Open_Face): Ditto (stream).
+	(load_face_in_embedded_rfork): Ditto (stream2).
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c: Add a fallback to guess the availability of the
+	`ResourceIndex' type.  It is used when built without configure
+	(e.g., a build with Jam).
+	* builds/mac/ftmac.c: Ditto.
+	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
+	explicitly, even if `ResourceIndex' is unavailable.
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: In checking of Mac OS X features,
+	all-in-one header file `Carbon.h' is replaced by the minimum
+	header file `CoreServices.h', similar to current src/base/ftmac.c.
+
+2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
+	sub-header when its code_count is 0.  Many Japanese Dynalab fonts
+	include such an empty sub-header (code_count == 0, first_code == 0
+	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
+
+2008-08-04  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
+	Savannah bug #23995.
+
+	* src/cid/cidload.c (parse_expansion_factor): New callback function.
+	(cid_field_records): Use it for `ExpansionFactor'.

+	Don't handle `ExpansionFactor'.
+
+2008-08-04  Bram Tassyns  <bramt@enfocus.be>
+
+	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which

+
+	Be more tolerant w.r.t. invalid entries in SFNT table directory.
+

+	adjust table count.
+	Add more trace messages.
+	(tt_face_load_font_dir): Updated.
+
+2008-07-30  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
+	assume that the first argument on the stack is the bottom-most
+	element.  Two reasons:
+
+	  o According to people from Adobe it is missing in the Type 2
+	    specification that pushing of additional, superfluous arguments
+	    on the stack is prohibited.
+
+	  o Acroread in general handles fonts differently, namely by popping
+	    the number of arguments needed for a particular operand (as a PS
+	    interpreter would do).  In case of buggy fonts this causes a
+	    different interpretation which of the elements on the stack are
+	    superfluous and which not.
+
+	Since there are CFF subfonts (embedded in PDFs) which rely on
+	Acroread's behaviour, FreeType now does the same.
+
+2008-07-27  Werner Lemberg  <wl@gnu.org>
+
+	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
+	fixes Savannah bug #23940.
+

+
+	* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
+	tt_cmap4_char_map_binary): Handle fonts which treat the last segment

+
+	Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.

+	Invert sids table only if `pure_cff' is set.
+	* src/cff/cffload.h: Updated.
+
+	* src/cff/cffobjs.c (cff_face_init): Updated.

+
+2008-07-05  Werner Lemberg  <wl@gnu.org>
+
+	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or

+	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
+	pixel, only check for dropouts if neither start nor end point lies
+	on a pixel center.  This fixes Savannah bug #23762.
+
+2008-06-29  Werner Lemberg  <wl@gnu.org>
+
+	* Version 2.3.7 released.
+	=========================
+
+
+	Tag sources with `VER-2-3-7'.
+
+	* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
+	version number to 2.3.7.
+
+	* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
+	builds/win32/visualc/freetype.dsp,

+	builds/win32/visualce/index.html,
+	builds/win32/visualce/freetype.dsp,
+	builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
+
+	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
+
+	* builds/unix/configure.raw (version_info): Set to 9:18:3.
+
+	* docs/release: Updated.
+
+2008-06-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
+	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.
+
+2008-06-27  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
+	Horizontal_Gray_Sweep_Drop): Test for intersections which
+	degenerate to a single point can be ignored; this has been confirmed
+	by Greg Hitchcock from Microsoft.  (This was commented out code.)
+
+2008-06-26  Werner Lemberg  <wl@gnu.org>
+
+	Improve navigation in API reference.
+
+	* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
+	(html_header_6): This.
+	(html_header_3, html_header_3i, html_header_4, html_header_5,

+
+2008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
+	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
+	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
+	ResourceIndex type definition.  The macro does not inform the type
+	availability.
+	* src/base/ftmac.c: More parentheses are inserted to clarify the
+	conditionals to disable legacy APIs in `10.5 and later' cases.  If
+	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
+
+2008-06-24  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
+	mode.
+
+	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
+	Draw_Sweep): No-dropout mode is value 2, not value 0.
+	(Draw_Sweep): Really skip dropout handling for no-dropout mode.
+
+2008-06-24  Werner Lemberg  <wl@gnu.org>
+
+	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
+	if it consists of one point only.  Based on a patch from Savannah
+	bug #23683 (from John Tytgat).
+
+2008-06-22  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
+	with IS_HINTED.
+
+	* docs/CHANGES: Updated.
+
+2008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
+	but LDFLAGS does not, import it to LDFLAGS.  The option is used to
+	specify non-default SDK on Mac OS X (e.g., universal binary SDK for
+	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
+	recommends to add the option only to CFLAGS, LDFLAGS should include
+	it because libfreetype.la is built with -no-undefined.  This fixes a
+	bug reported by Ryan Schmidt in MacPorts,
+	http://trac.macports.org/ticket/15331.
+
+2008-06-21  Werner Lemberg  <wl@gnu.org>
+
+	Enable access to the various dropout rules of the B&W rasterizer.
+	Pass dropout rules from the TT bytecode interpreter to the
+	rasterizer.

+	FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
+
+	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
+	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
+	OpenType specification.
+	Fix mode 4 computation.
+	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
+	mode to FT_OUTLINE_XXX flags.
+
+	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
+
+2008-06-19  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffobjs.c (cff_face_init): Compute final
+	`dict->units_per_em' value before assigning it to
+	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
+	scaled incorrectly if the font matrix is non-standard.  This fixes
+	Savannah bug #23630.
+
+	* docs/CHANGES: Updated.
+
+2008-06-19  Werner Lemberg  <wl@gnu.org>
+
+	* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix

+
+2008-06-15  George Williams  <gww@silcom.com>
+
+	* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set

+	specification.
+
+2008-06-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
+	from clobbering.  Patch from Savannah bug report #23556.
+
+	* docs/CHANGES: Document it.
+
+2008-06-10  Werner Lemberg  <wl@gnu.org>
+
+	* autogen.sh: Add option `--install' to libtoolize.
+
+2008-06-10  Werner Lemberg  <wl@gnu.org>

+
+	* src/base/ftobjs.c (open_face): Check `clazz->init_face' and
+	`clazz->done_face'.
+
+2008-06-09  VaDiM  <s_sliva@rambler.ru>
+
+	Support debugging on WinCE.  From Savannah patch #6536; this fixes
+	bug #23497.
+
+	* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
+	as a replacement for OutputDebugStringA (which WinCE doesn't have).
+	Update all callers.
+	(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
+	environment variables.
+
+2008-06-09  Werner Lemberg  <wl@gnu.org>
+
+	* README.CVS: Updated.
+
+	* builds/unix/configure.raw, builds/unix/freetype-config.in: Updated

+
+	* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
+
+
+	* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
+	for sane value.
+	Fix typo.
+
+
+	* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
+
+
+	* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
+	`last_point'.
+
+
+	* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
+	`maxTwilightPoints'.
+
+2008-06-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
+	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
+
+2008-06-03  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftcache.h (FTC_FaceID): Change type back to
+	FT_Pointer.  Reported by Ian Britten <britten@caris.com>.
+
+2008-06-02  Werner Lemberg  <wl@gnu.org>
+
+	Emit header info for defined FreeType objects in reference.
+
+	* src/tools/docmaker/content.py (re_header_macro): New regexp.

+	header_location_footer): New strings.
+	(HtmlFormatter::__init__): Pass `headers' dictionary.
+	(HtmlFormatter::print_html_field): Don't emit paragraph tags.
+	(HtmlFormatter::print_html_field_list): Emit empty paragraph.

+
+2008-06-01  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
+	FT_INCREMENTAL_H): Added.
+
+2008-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/sources.py (SourceBlock::__init__): While

+	found.
+
+2008-05-28  Werner Lemberg  <wl@gnu.org>
+

+	block_footer_middle): Beautify output.
+
+2008-05-25  Werner Lemberg  <wl@gnu.org>
+
+	* src/raster/ftraster.c (fc_black_render): Return 0 when we are

+
+	* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
+	of the graphics state for subglyphs to...
+	(TT_Hint_Glyph): This function.
+	Hinting instructions for a composite glyph apparently refer to the
+	just hinted subglyphs, not the unhinted, unscaled outline.  This
+	seems to fix Savannah bugs #20973 and (at least partially) #23310.
+
+2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
+	`aface' is returned by FT_New_Face_From_FOND().  The patch was

+
+2008-05-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
+	correction for pixel boundary.  Without this patch, the effect can
+	be cumulative under certain circumstances, making glyphs taller and
+	taller after each call.  This fixes Savannah bug #19976.
+
+2008-05-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
+	This fixes Savannah bug #23280.
+
+	* docs/CHANGES: Updated.
+
+2008-05-18  David Turner  <david@freetype.org>
+
+	* src/psnames/psmodule.c (ft_wgl_extra_unicodes,
+	ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
+	ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
+	declarations non-global.
+
+	* src/type1/t1load.c: Add missing comment.
+
+2008-05-17  Sam Hocevar  <samh>
+
+	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
+	glyphs correctly.  Patch from Savannah bug #23277.
+
+2008-05-16  Werner Lemberg  <wl@gnu.org>
+
+	* docs/CHANGES: Updated.
+
+2008-05-16  Sergey Tolstov  <stolstov@esri.com>
+
+	Improve support for WGL4 encoded fonts.
+
+	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.

+	ft_wgl_extra_glyph_name_offsets): New arrays.
+	(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
+	(ps_unicodes_init): Use them to add additional Unicode mappings.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
+	<op_closepath>: `closepath' without a path is a no-op, not an error
+	(cf. the PS reference manual).
+
+	Reported by Martin McBride.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
+
+2008-05-15  Werner Lemberg  <wl@gnu.org>
+
+	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
+	which contains a single but empty entry.  This is technically
+	invalid (since it must end with `return'), but...
+
+	Reported by Martin McBride.
+
+2008-05-14  Werner Lemberg  <wl@gnu.org>
+
+	Finish fix of scaling bug of CID-keyed CFF subfonts.
+
+	* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
+	(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
+	functions.
+
+	* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
+	provide global hinting data for both the top-font and all subfonts
+	(with proper scaling).
+
+	* src/cff/cffobjs.c (cff_make_private_dict): New function, using
+	code from `cff_size_init'.
+	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
+	Use CFF_Internal and handle subfonts.
+	(cff_face_init): Handle top-dict and subfont matrices correctly;
+	apply some heuristic in case of unlikely matrix concatenation
+	results.  This has been discussed with people from Adobe (thanks
+	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
+	and not correct.
+
+	* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
+
+	* src/cff/cffgload.c (cff_builder_init): Updated.
+	(cff_decoder_prepare): Handle hints globals for subfonts.
+	Update all callers.
+	(cff_slot_load): Handling scaling of subfonts properly.
+
+	* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.

+
+2008-05-04  Werner Lemberg  <wl@gnu.org>
+
+	First steps to fix the scaling bug of CID-keyed CFF subfonts,

+
+	* src/base/cff/cffparse.c (power_tens): New array.

+	precision loss.  This is not used yet.
+	Update all callers.
+	(cff_parse_fixed_thousand): Replace with...
+	(cff_parse_fixed_scaled): This function.  Update all callers.
+
+2008-05-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
+	transformation since it recursively calls FT_Load_Glyph.  This fixes
+	Savannah bug #23143.
+
+2008-04-26  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'

+	maximum CID value in CID-keyed CFFs.
+	Handle FT_FACE_FLAG_CID_KEYED flag.
+
+	* docs/CHANGES: Document it.
+
+
+	Fix CFF font matrix calculation and improve precision.
+
+	* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
+	part is zero.
+	(cff_parse_font_matrix): Simplify computation of `units_per_em';
+	this prevents overflow also.
+
+
+	Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
+
+	* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
+	(cid_get_ros): New function.

+	(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
+
+2008-03-21  Laurence Darby  <ldarby>
+
+	* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'.  Patch from
+	Savannah bug #22675.
+
+2008-03-13  Derek Clegg  <dclegg@apple.com>
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.

+
+2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
+	synthesis.  For any face of a specified FOND, always the name for
+	the first face was used.  Except of a FOND that refers multiple
+	Type1 font files, wrong synthesized font names are not used at all,
+	so this is an invisible bug.  A few limit checks are added too.
+
+	* builds/mac/ftmac.c: Ditto.
+
+2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/unix/configure.raw: Split compiler option to link Carbon
+	frameworks to one option for CoreServices framework and another
+	option for ApplicationServices framework.  The split options can be
+	managed by GNU libtool to avoid unrequired duplication when FreeType
+	is linked with other applications.  Suggested by Daniel Macks,
+	Savannah bug #22366.
+
+2008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>
+
+	* src/truetype/ttinterp.c (Ins_IUP): Check number of points.  Fix

+
+	* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
+	handle by its value instead of ResError(), fix provided by Deron
+	Kazmaier.  According to the Resource Manager Reference,
+	GetResource(), Get1Resource(), GetNamedResource(),
+	Get1NamedResource() and RGetResource() set noErr but return NULL
+	handle when they can not find the requested resource.  These
+	functions never return undefined values, so it is sufficient to
+	check if the handle is not NULL.
+
+	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

+	Improvement of POSIX resource-fork accessor to load unsorted
+	references in a resource.  In HelveLTMM (resource-fork PostScript
+	Type1 font bundled with Mac OS X since 10.3.x), the appearance order

+
+	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

+
+2007-12-14  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
+	division too early; otherwise the most significant digit(s) of the
+	final result are lost as the value is truncated to an integer.  This
+	fixes Savannah bug #21794 (where the patch has been posted too).
+
+2007-12-06  Fix  <4d876b82@gmail.com>
+
+	Pass options from one configure script to another as-is (not

+
+2007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
+	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
+	cannot mmap() the specified file and cannot seek to head of the
+	specified file, it returns NULL stream and FT_Open_New() returns the
+	error immediately.  On MacOS, most legacy MacOS fonts fall into such
+	a scenario because their data forks are zero-sized and cannot be
+	sought.  To proceed to guessing of resource fork fonts, the
+	functions for legacy MacOS font must properly handle the NULL stream
+	returned by FT_New_Stream().
+
+	* src/base/ftobjs.c (IsMacBinary): Return error
+	FT_Err_Invalid_Stream_Operation immediately when NULL stream is
+	passed.
+	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
+	to fallback.  Originally, legacy MacOS font is tested in the cases
+	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
+	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
+	.dfont header is combined).  Now the case of
+	FT_Err_Cannot_Open_Stream is included.
+
+	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
+	skip FT_Stream_Seek(), which seeks to the head of stream, and
+	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
+	for a NULL stream causes a Bus error on Mac OS X.
+	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
+	immediately if passed stream is NULL.
+	(raccess_guess_apple_single): Ditto.
+
+2007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix for Carbon incompatibilities since Mac OS X 10.5,
+	proposed by Sean McBride.
+
+	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
+
+	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
+	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
+	Carbon functions from a forked process is classified as unsafe
+	by Apple.  All Carbon-dependent functions should be deprecated.
+
+	* src/base/ftmac.c: Use essential header files
+	<CoreServices/CoreServices.h> and
+	<ApplicationServices/ApplicationServices.h> instead of
+	all-in-one header file <Carbon/Carbon.h>.
+
+	Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
+	genuine macro PATH_MAX.
+
+	Add fallback macro for kATSOptionFlagsUnRestrictedScope which
+	is not found in Mac OS X 10.0.
+
+	Multi-character constants ('POST', 'sfnt' etc) are replaced by
+	64bit constants calculated by FT_MAKE_TAG() macro.
+
+	For the index in the segment of resource fork, new portable
+	type ResourceIndex is introduced for better compatibility.
+	This type is since Mac OS X 10.5, so it is defined as short
+	when built on older platforms.
+
+	(FT_ATSFontGetFileReference): If build target is only the systems
+	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
+
+	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
+	and newer or 64bit platform, because legacy type FSSpec type is
+	removed completely.
+
+	(FT_New_Face_From_FSSpec): Ditto.
+
+2007-11-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
+	fixes Savannah bug #21485.
+
+2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>
+
+	* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
+	can handle the font at all, then check `face_index'.  Otherwise, the
+	driver might return the wrong error code.  This fixes Savannah bug
+	#21468.
+
+2007-10-21  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
+	support for bit 8 of the `fsSelection' field in the `OS/2' table.
+	MS is already using this; hopefully, this becomes part of OpenType
+	1.5.
+	Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
+	(WWS_SUBFAMILY).
+
+2007-10-20  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
+	Add `td.left' element to CSS.
+	(toc_section_enter): Use it.
+
+2007-10-18  David Turner  <david@freetype.org>
+
+	* include/freetype/freetype.h, src/base/ftobjs.c: Rename API
+	functions related to cmap type 14 support to the
+	`FT_Object_ActionName' scheme:
+
+	  FT_Get_Char_Variant_index     -> FT_Face_GetCharVariantIndex
+	  FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
+	  FT_Get_Variant_Selectors      -> FT_Face_GetVariantSelectors
+	  FT_Get_Variants_Of_Char       -> FT_Face_GetVariantsOfChar
+	  FT_Get_Chars_Of_Variant       -> FT_Face_GetCharsOfVariant
+
+	Update documentation accordingly.
+
+	* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
+	Make the code a little more consistent with FreeType coding
+	conventions and modify the cmap14 functions that returned a newly
+	allocated array to use a persistent vector from the TT_CMap14 object
+	instead.
+
+	(TT_CMap14Rec): Provide array and auxiliary data for result.
+	(tt_cmap14_done, tt_cmap14_ensure): New functions.

+	same as the other value.
+
+2007-04-02  David Turner  <david@freetype.org>
+
+	Add special code to detect `extra-light' fonts and do not snap their

+	* src/autofit/afloader.c (af_loader_load_g): In the case of
+	monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.

+	(af_loader_load_g): Disable the warper (i.e., the light hinting

+	`modules.cfg').
+
+	* src/sfnt/ttsbit0.h: Remove.
+
+	* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.
+
+2007-01-12  David Turner  <david@freetype.org>
+
+	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
+	bug in the bitmap emboldener if the pitch of the source bitmap is
+	much larger than its width.
+
+	* src/truetype/ttinterp.c (Update_Max): Fix aliasing-related
+	compilation warning.
+
+2007-01-12  Werner Lemberg  <wl@gnu.org>

+	crash with some Mac OS X .dfont files.  Submitted by Masatake
+	Yamato.
+
+	* autogen.sh: Small fix to get it working on Mac OS X properly:
+	The issue is that GNU libtool is called `glibtool' on this platform,
+	and we must call `glibtoolize', since `libtoolize' doesn't exist.
+
+2007-01-10  David Turner  <david@freetype.org>
+
+	* all-sources: Tag all sources with VER-2-3-0-RC1 and
+	VER-2-3-0.

+	values.
+
+2007-01-08  David Turner  <david@freetype.org>
+
+	* docs/CHANGES: Updated.
+
+	* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add

+	`gasp' table, in order to avoid potential problems with later
+	versions.
+
+	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for
+	<freetype/ftgasp.h>.
+
+	* src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),
+	modules.cfg (BASE_EXTENSIONS), builds/win32/visualc/freetype.dsp,
+	builds/win32/visualc/freetype.vcproj: Add src/base/ftgasp.c to the

+
+2007-01-07  Werner Lemberg  <wl@gnu.org>
+
+	* src/cid/cidparse.c (cid_parser_new): Improve error message for

+	Scan for `/sfnts' token.
+
+2007-01-07  Werner Lemberg  <wl@gnu.org>
+
+	* src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.
+
+2007-01-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffload.c (cff_index_init): Remove unused variable.
+	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.
+
+2007-01-04  David Turner  <david@freetype.org>
+
+	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts

+
+
+	Do not allocate interpreter-specific tables in memory if we are not
+	going to load glyphs with the bytecode interpreter anyway.
+
+	* src/truetype/ttgload.c (tt_loader_init): Load execution context
+	only if glyph is hinted.
+	Updated.
+	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
+	and `cvs_ready'.
+	Add `tt_size_ready_bytecode' declaration.
+	* src/truetype/ttobjs.c (tt_size_done_bytecode,
+	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
+	(tt_size_init): Move most code into `tt_size_init_bytecode'.
+	(tt_size_done): Move most code into `tt_size_done_bytecode'.
+	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
+
+
+	Don't extract the metrics table from the SFNT font file.  Instead,
+	reparse it on each glyph load.  The runtime difference is not
+	noticeable, and it can save a lot of heap memory when memory-mapped
+	files are not used.
+
+	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
+	`horz_metrics_offset' and `vert_metrics_offset'.
+	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
+	Updated.
+
+
+	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
+
+
+	Do not load the CFF index offsets into memory, since this wastes a
+	*lot* of heap memory with large Asian CFF fonts.  There is no
+	significant performance loss.
+
+	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
+	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
+	`data_size'.

+	* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
+	cff_charset_cid_to_gindex): New functions.
+	(cff_new_index): Renamed to...
+	(cff_index_init): This.  Update all callers.
+	Updated -- some code has been moved to `cff_index_load_offsets'.
+	(cff_done_index): Renamed to...

+	stream offsets.
+	(cff_charset_compute_cids): Set `num_glyphs' field.
+	(cff_encoding_load): Updated.
+
+	* src/cff/cffgload.c (cff_slot_load): Updated.

+
+	* docs/TODO: Remove obsolete items.
+
+	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
+	(TWorker): This.
+	Remove `count_table' and `memory'.
+	Make `grays' a pointer.
+	(TRaster): New structure.
+	(count_table): New static array.

+	ft_black_set_mode, ft_black_render): Updated.
+	(ft_black_init): Don't initialize `count_table'.
+	(ft_black_reset): Use the render pool.  This saves about 6KB of
+	heap space for each FT_Library instance.
+
+	* src/smooth/ftgrays.c (TRaster): Replaced with...
+	(TWorker): This.
+	Remove `memory'.
+	(TRaster): New structure.
+
+	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
+	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
+	gray_render_span, gray_raster_render): Updated.
+	(gray_raster_reset): Use the render pool.  This saves about 6KB of
+	heap space for each FT_Library instance.
+
+	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
+	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
+	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
+	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
+	the optimization is no longer experimental.
+
+	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
+	Remove a typo that results in no hinting and a memory leak with some
+	large Asian CFF fonts.
+
+	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
+	which happens when FT_Done_Library is called with still opened
+	CFF_Faces in it.  We need to close all faces before destroying the
+	modules, or else some bad things (memory leaks) may happen.
+
+2007-01-02  Werner Lemberg  <wl@gnu.org>
+
+	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
+	Remove compiler warning.
+
+2007-01-02  David Turner  <david@freetype.org>

+
+2006-12-31  Masatake YAMATO  <jet@gyve.org>
+
+	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New
+	function.
+	Check uniqueness of the gid pairs.
+	(gxv_kern_subtable_fmt0_validate): Move some code to

+	  http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5
+
+2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c: Specialized for Mac OS X only.
+	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
+	* builds/unix/configure.raw: Ditto.  When explicit switches for
+	FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
+	builds/mac/ftmac.c is used instead of default src/base/ftmac.c.
+
+2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.

+	* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
+	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
+	* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
+	that cannot be built at present.
+
+2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftobjs.c: Improvement of resource fork handler for

+	  http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
+	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
+	format or .dfont, to simulate the face index number counted by ftmac.c.
+	(IsMacResource): Return the number of scalable faces correctly.
+
+2006-12-10  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (version): Protect against `distclean' target.
+
+2006-12-09  Werner Lemberg  <wl@gnu.org>
+
+	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'
+	or `type'.
+
+	* builds/freetype.mk (version): Extracted from freetype.h, using
+	GNU make's built-in string functions.
+	(refdoc): Use $(version) instead of static version number.
+
+2006-12-08  Werner Lemberg  <wl@gnu.org>
+
+	* builds/toplevel.mk (dist): Extract version number from freetype.h.
+
+2006-12-08  Vladimir Volovich  <vvv@vsu.ru>
+
+	* src/tools/apinames.c (State): Remove final comma in structure --
+	xlc v5 under AIX 4.3 doesn't like this.
+
+2006-12-07  David Turner  <david@freetype.org>
+
+	* src/autofit/afloader.c (af_loader_load_g): Small adjustment
+	to the spacing of auto-fitted glyphs.  This only impacts rare
+	cases (e.g., Arial Bold at rather small character sizes).
+
+2006-12-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.
+
+2006-12-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are

+	(tt_name_entry_ascii_from_ucs4): Removed.
+
+
+	* include/freetype/ftxf86.h: Fix and extend comment so that it

+
+	* src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.
+

+	variable.
+
+2006-11-26  Pierre Hanser  <hanser@club-internet.fr>

+
+2006-11-25  David Turner  <david@freetype.org>
+
+	* src/autofit/afhints.c	(af_glyph_hints_dump_points,
+	af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
+	Add stubs to link the `ftgrid' test program when debugging is
+	disabled in the auto-hinter.
+
+2006-11-23  David Turner  <david@freetype.org>
+
+	* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,

+
+2006-11-22  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #15553.
+
+	* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
+	program after a change from mono to grayscaling (and vice versa).
+	Use correct constant for comparison to get `exec->grayscale'.
+
+2006-11-18  Werner Lemberg  <wl@gnu.org>
+
+	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
+	test for a valid glyph index must be deferred to the font drivers.
+	This patch fixes Savannah bug #18301.
+
+	* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
+	(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
+	src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c

+	src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
+	(FNT_Load_Glyph): Check validity of `glyph_index'.
+
+2006-11-13  David Turner  <david@freetype.org>
+
+	* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
+	`enhancements' are still too buggy for general use.
+
+	* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
+	FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
+	when building the library to change the default LCD filter to be
+	used.  This is only useful for experimentation.
+
+	* include/freetype/ftlcdfil.h: Update documentation.
+
+2006-11-10  David Turner  <david@freetype.org>
+
+	* src/smooth/ftsmooth.c: API change for the LCD
+	filter.  The FT_LcdFilter value is an enumeration describing which
+	filter to apply, with new values FT_LCD_FILTER_LIGHT and
+	FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
+	algorithm which produces strong color fringes for everything
+	except very-well hinted text).
+
+	* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
+	second parameter to an enum type.
+
+	* src/base/ftlcdfil.c (USE_LEGACY): Define.
+	(_ft_lcd_filter): Rename to...
+	(_ft_lcd_filter_fir): This.

+	callback and update other fields.
+
+	* src/smooth/ftsmooth.c (ft_smooth_render_generic)
+	[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
+	Other minor improvements.
+
+	* src/autofit/aflatin.c: Various tiny improvements that drastically
+	improve the handling of serif fonts and of LCD/LCD_V hinting modes.
+	(af_latin_hints_compute_edges): Fix typo.
+	(af_latin_compute_stem_width): Take better care of diagonal stems.
+
+2006-11-09  David Turner  <david@freetype.org>
+
+	* src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
+	typo which created a variable-used-before-initialized bug.
+
+2006-11-07  Zhe Su  <james.su@gmail.com>
+
+	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
+	also.
+
+2006-11-03  Werner Lemberg  <wl@gnu.org>
+
+	* src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.
+
+2006-11-02  David Turner  <david@freetype.org>
+
+	Add a few tweaks to better handle serif fonts.
+	Add more debugging messages.
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
+	segments that are less than 1.5 pixels high.  This gets rid of
+	*many* corner cases with serifs.
+	(af_latin_align_linked_edge): Add logging message.
+	(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
+	Add logging messages.
+	Handle AF_EDGE_FLAG flag specially.
+
+	* src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
+	_af_debug_disable_blue_hints, and _af_debug_hints variables.
+
+	* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
+	Update external declarations.
+	(af_corner_orientation, af_corner_is_flat): Replaced by...
+
+	* include/freetype/internal/ftcalc.h (ft_corner_orientation,
+	ft_corner_is_flat): These declarations.
+
+	* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
+	Comment out.  Replaced by...
+
+	* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
+	These functions.  Update all callers.
+	(FT_Add64) [!FT_LONG64]: Simplify.
+
+	* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
+	(af_direction_compute): Add a missing FT_ABS call.  This bug caused
+	production of garbage by missing lots of segments.
+
+	* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.
+
+	* src/autofit/afloader.c (af_loader_init, af_loader_done)
+	[AF_DEBUG]: Set _af_debug_hints.
+
+
+	* src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H.
+	(psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat
+	and ft_corner_orientation.

+
+	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
+	better deal with broken Asian fonts with strange glyphs, having
+	self-intersections and other peculiarities.  The used algorithm is
+	based on the nonzero winding rule.
+
+2006-10-23  David Turner  <david@freetype.org>
+
+	Speed up the CFF font loader.  With some large CFF fonts,
+	FT_Open_Face is now more than three times faster.
+
+	* src/cff/cffload.c (cff_get_offset): Removed.
+	(cff_new_index): Inline functionality of `cff_get_offset'.
+	(cff_charset_compute_cids, cff_charset_free_cids): New functions.
+	(cff_charset_done): Call `cff_charset_free_cids'.
+	(cff_charset_load): Call `cff_charset_compute_cids'.
+	(cff_encoding_load) <Populate>: Ditto, to replace inefficient loop.
+
+	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
+	with FT_NEXT_XXX.

+	to PCF_Face_Done can do the clean-up in case of error.
+	Protect against invalid string offsets.

+
+2006-06-26  Werner Lemberg  <wl@gnu.org>
+
+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Handle fonts correctly which
+	don't have a POINT_SIZE property.  This fixes Savannah bug #16914.
+
+2006-06-26  Jens Claudius  <jens.claudius@yahoo.com>
+
+	* src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15.
+	(t1_decoder_parse_charstrings): Operator with
+	opcode 15 pops its two arguments.
+	Handle the case where the pops of an othersubr may be part of a
+	subroutine.
+	Handle unknown othersubrs gracefully: count their operands and let
+	the following pop operators push the operands as the results onto
+	the Type1 stack.
+	Improve handling of setcurrentpoint opcode.
+
+2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>
+
+	The Type 1 parser now skips over top-level procedures as required
+	for a `Simplified Parser'.  This makes the parser more robust as it
+	doesn't poke around in PostScript code.  Additionally, it makes the
+	FontDirectory hackery in src/type1/t1load.c unnecessary.
+
+	* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
+	(skip_literal_string): Add FT_Error as return value.
+	Handle escapes better.

+	* include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add
+	`first_point' member.
+
+	* src/truetype/ttgload.c (tt_prepare_zone): Initialize
+	`first_point'.
+	(TT_Process_Composite_Glyph): Always untouch points.
+
+	* src/truetype/ttinterp.c (Ins_SHC): Fix computation of
+	`first_point' and `last_point' in case of composite glyphs.
+	(Ins_IUP): Fix computation of `end_point'.
+
+2006-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
+	Mac.  The original patch was written by David Sachitano and Lawrence
+	Coopet, and modified by Sean McBride for MPW compatibility.  Only
+	required data are converted; unused data are left in big endian.
+
+	* src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
+	Mac OS X platforms.

+	StyleMapping table.
+	(count_faces): Call `HUnlock' after all FOND utilization.
+
+2006-06-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Public API of TrueTypeGX, OpenType, and classic kern table validator
+	should return `FT_Err_Unimplemented_Feature' if validation service
+	is unavailable (disabled in `modules.cfg').  It is originally
+	suggested by David Turner, cf.
+	http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

+
+2006-06-08  Werner Lemberg  <wl@gnu.org>

+	errors.
+
+2006-06-07  David Turner  <david@freetype.org>
+
+	* src/type1/t1afm.c (KERN_INDEX): Make it more robust.
+	(T1_Read_Metrics): Fix memory leak which happened when the metrics
+	file doesn't have kerning pairs.  This fixes Savannah bug #16768.
+
+2006-06-06  David Turner  <david@freetype.org>
+
+	Fix memory leak described in Savannah bug #16759.
+
+	We change `ps_unicodes_init' so that it also takes a
+	`free_glyph_name' callback to release the glyph names returned by
+	`get_glyph_name'
+
+	* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
+	Renamed to ...
+	(PS_GetGlyphNameFunc): This.

+
+
+2006-06-04  David Turner  <david@freetype.org>
+
+	* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
+	`item_size == 0' as well -- though this sounds weird, it can
+	theoretically happen.  This fixes Savannah bug #16669.
+
+	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
+	of `face->num_glyphs' which missed the last glyph, due to
+	the offset-by-1 computation, since the PFR format doesn't
+	guarantee that glyph index 0 corresponds to the `missing
+	glyph.  This fixes Savannah bug #16668.
+
+2006-05-25  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
+	`-no-undefined'.  Reported by Christian Biesinger.
+
+2006-05-19  Brian Weed  <bw@imaginengine.com>
+
+	* builds/win32/visualc/freetype.dsp: Release libraries no longer
+	have debug information, and debug libraries use `C7 compatible'
+	debug info.
+
+2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Apply patch by Derek Clegg to fix two memory leaks in the MacOS
+	resource fork handler.  This fixes Savannah bug #16631.

+
+2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
+	its content cannot be parsed as supported font.  This fixes
+	the second part of Savannah bug #16590.
+
+2006-05-18  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
+	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
+
+2006-05-17  David Turner  <david@freetype.org>
+
+	This is a major patch used to drastically improve the performance of
+	loading glyphs.  This both speeds up loading the glyph vectors
+	themselves and the auto-fitter module.
+
+	We now use inline assembler code with GCC to implement `FT_MulFix',
+	which is probably the most important function related to the
+	engine's performance.
+
+	The resulting speed-up is about 25%.
+
+
+	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
+	`cursor' and `limit'.
+
+	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
+	New functions.
+	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
+	[TEST]: Remove.
+
+	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
+	code.
+
+	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
+	`FT_ZERO'
+	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
+	(af_glyph_hints_reload: Rewrite recognition of weak points.
+
+	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
+	constant values out of the loops.
+
+	* src/autofit/aftypes.h: Updated.
+
+	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
+
+	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
+	product to get orientation.
+
+	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
+	(FT_Stream_OpenGzip): Use it to handle small files directly in
+	memory.
+
+	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode):
+	Improve performance.
+
+	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
+	`limit'.
+
+	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
+	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
+	exceedingly large values of number of contours.  Speed up by
+	reducing the number of loops.
+
+	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
+
+
+	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
+	used to detect rogue clients from 4 to 16.  This is to prevent some
+	segmentation faults with fonts like `KozMinProVI-Regular.otf' which
+	comes from the Japanese Adobe Reader Asian Font pack.
+
+2007-05-17  Werner Lemberg  <wl@gnu.org>
+
+	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
+	fixes the first part of Savannah bug #16590.
+
+2006-05-16  Werner Lemberg  <wl@gnu.org>
+
+	* docs/PROBLEMS: Updated icl issues.

+
+	[cff] Make Adobe CFF engine work correctly on 64bit hosts.
+
+	Reported by numerous people on the `freetype-devel' list.  Without
+	this fix, glyphs aren't properly aligned on a common baseline.
+
+	On 64bit systems, `FT_Pos' expands to `long int', having a width of
+	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on
+	64bit hosts also.  Wrong casts filled up the blues arrays with
+	incorrect values.  Note that all blues values are accessed with the
+	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
+
+	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
+	`data', not `CF2_Fixed'.
+	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
+	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.
+	* src/cff/cf2blues.c (cf2_blues_init): Updated.

+2013-05-04  Werner Lemberg  <wl@gnu.org>
+
+	More fixes for clang's `sanitize' feature.
+
+	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for
+	computations which use the left shift operator and convert to signed
+	as the last step.
+	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,

+
+	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,

+
+	[cff] Add a new Type 2 interpreter and hinter.
+
+	This work, written by Dave Arnold <darnold@adobe.com> and fully
+	integrated into FreeType by me, is a donation by Adobe in
+	collaboration with Google.  It is vastly superior to the old CFF
+	engine, and it will replace it soon.  Right now, it is still off by
+	default, and you have to explicitly select it using the new
+	`hinting-engine' property of the cff driver.
+
+	For convenience, (most of) the new files are committed separately.

+	engine listens to them).
+	* src/cff/cffgload.c: Include `cf2ft.h'.
+	(cff_decoder_prepare): Initialize `current_subfont'.
+	(cff_build_add_point): Handle Adobe engine which uses 16.16
+	coordinates.

+
+2013-03-31  Werner Lemberg  <wl@gnu.org>
+
+	* configure: Use egrep, not grep.
+
+	Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
+
+2013-03-29  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftlcdfil.h: Add description of color filtering.
+
+	Based on a contribution from Antti S. Lankila <alankila@bel.fi>

+
+	[autofit] Minor.
+
+	* src/autofit/afmodule.c (af_property_set): Typo.

+
+2013-03-21  Werner Lemberg  <wl@gnu.org>
+
+	* configure: Automatically test for `gmake' also.
+

+
+2013-03-21  Peter Breitenlohner  <peb@mppmu.mpg.de>
+
+	Respect CONFIG_SHELL from the environment.
+
+	Some large packages using FreeType have to use a broken (deficient)
+	/bin/sh.  The configure scripts (as generated by Autoconf) are
+	clever enough to find a better shell and put that one into the
+	environment variable CONFIG_SHELL.  If that environment variable is
+	already set the script skips the test and assumes to be already
+	running under a good shell.
+
+	* builds/unix/detect.mk: Honour CONFIG_SHELL.
+	* builds/unix/unix-def.in (SHELL): Define.
+
+2013-03-21  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah patch #7971.
+
+	* configure: Handle MAKE environment variable also.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>

+	Fix Savannah bug #38538.
+
+	* builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
+	builds/wince/ftdebug.c (FT_Throw): Add function.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>
+
+	[raster] Remove dead code.
+
+	* src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
+	src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
+
+2013-03-17  Werner Lemberg  <wl@gnu.org>
+
+	* src/pshinter/pshpic.h (GET_PIC): Use correct container.
+
+2013-03-15  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
+
+	The previous version was not backwards compatible.  Reported by
+	Behdad.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
+
+	FT_Err_XXX and friends are no longer directly used in the source
+	code.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	New error management macros.
+
+	* include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
+	* include/freetype/fttypes.h: ... this file.
+	(FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
+	macros.
+
+	* include/freetype/freetype.h: Updated.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use FT_Err_Ok only.
+
+	This is a purely mechanical conversion.
+
+2013-03-14  Werner Lemberg  <wl@gnu.org>
+
+	*/*: Use `FT_THROW'.
+
+	This is essentially a mechanical conversion, adding inclusion of
+	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
+	stand-alone compiling modes of the rasterizer modules.
+
+	To convert the remaining occurrences of FT_Err_XXX and friends it is
+	necessary to rewrite the code.  Note, however, that it doesn't harm
+	if some cases are not handled since FT_THROW is a no-op.
+
+2013-03-13  Werner Lemberg  <wl@gnu.org>
+
+	Introduce `FT_THROW' macro.
+
+	The idea is to replace code like
+
+	  return FT_Err_Foo_Bar;
+
+	or
+
+	  return CFF_Err_Foo_Bar;
+
+	with
+
+	  return FT_THROW( Foo_Bar );
+
+	The FT_THROW macro has two functions:
+
+	  . It hides the module specific prefix.
+
+	  . In debug mode, it calls the empty function `FT_Throw' which can
+	    be thus used to set a breakpoint.
+
+	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.
+	(FT_Throw): New prototype.
+	* src/base/ftdebug.c (FT_Throw): New function.
+
+2013-03-12  Werner Lemberg  <wl@gnu.org>
+
+	Remove `FT_KEEP_ERR_PREFIX'.
+
+	The idea is to always have FT_ERR_PREFIX available internally.
+
+	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
+	undefinition of FT_ERR_PREFIX
+
+	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,
+	src/sfnt/sferrors.h: Updated.
+
+2013-03-11  Werner Lemberg  <wl@gnu.org>
+
+	[gxvalid] Fix module error.
+
+	* src/gxvalid/gxverror.h (FT_ERR_BASE): Define as
+	FT_Mod_Err_GXvalid.
+	* include/freetype/ftmoderr.h: Add module error for `GXvalid'.
+
+2013-03-11  Werner Lemberg  <wl@gnu.org>
+
+	Always use module related error codes.
+
+	* src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
+	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use
+	`FT_ERROR_BASE'.
+
+	* src/type1/t1load.c (parse_encoding): Use
+	T1_Err_Unknown_File_Format.
+
+2013-03-08  Werner Lemberg  <wl@gnu.org>
+
+	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.
+
+	Problem reported by Khaled Hosny <khaledhosny@eglug.org>.
+

+
+2013-02-19  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[base] New bisecting BBox_Cubic_Check (disabled).
+
+	* src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm
+	for extremum search built around simple condition that defines
+	which half contains the extremum.
+
+2013-02-18  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[tools] Update BBox testing tool.
+
+	* src/tools/test_bbox.c: Add another cubic outline with exact BBox.
+	(REPEAT): Increase the number of benchmarking cycles.
+	(profile_outline): Tweak output formatting.
+
+2013-02-02  Werner Lemberg  <wl@gnu.org>
+
+	Fix Savannah bug #38235.
+
+	* builds/unix/configure.raw: Don't generate `freetype-config' and
+	`freetype.pc'.
+
+	* builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,
+	build_libtool_libs, ft_version): New variables to be substituted.
+	(freetype-config, freetype.pc): New rules to generate those files.
+
+	* builds/unix/freetype-config.in: Remove code for handling `rpath'.
+	The use of $rpath has been accidentally removed in a patch from
+	2009-12-22, and apparently noone has missed it since.
+	Use `%' instead of `@' as a variable substitution marker.
+	Use quotes.
+
+	* builds/unix/freetype.in: Use `%' instead of `@' as a variable
+	substitution marker.
+	Use quotes.
+
+2013-02-07  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
+
+	BTW, Greg agrees that the OpenType specification is missing the list
+	of GS variables which will always be reset to the default values
+	after the `prep' table has been executed.
+
+2013-02-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
+
+	Up to now, we simply took a snapshot of the Graphics State after the
+	`prep' table has been executed, and right before a glyph's bytecode
+	was run it got reloaded.  However, as Greg Hitchcock has told us in
+	private communication, reference points get reset to zero in the MS
+	rasterizer and we follow in due course.  While reasonable, this is
+	undocumented behaviour.
+
+	Most notably, this fixes the rendering of Arial's `x' glyph in
+	subpixel hinting mode.
+
+2013-02-05  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] A better fix for Savannah bug #38211.

+
+	[sfnt] Fix broken pointer overflow checks.
+
+	Many compilers such as gcc and clang optimize away pointer overflow
+	checks `p + n < p', because pointer overflow is undefined behavior.
+	Use a safe form `n > p_limit - p' instead.
+
+	Also avoid possible integer overflow issues, for example, using
+	`num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'

+
+	[truetype] Improve sub-pixel code.
+
+	This patches fixes many issues with the ttsubpix implementation.
+
+	1. Data tables are defined, instead of declared, in the header, and
+	   thus copied into each source file that includes it.
+
+	2. These tables were defined as global, mutable, visible variables,
+	   and thus costing private RAM to every process that loads the
+	   library (> 50 KB / process, this is huge!).
+
+	   Additionally, this also made the library export the symbols
+	   completely needlessly.
+
+	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
+
+	Note that this doesn't try to fix the incredibly inefficient storage
+	format for the data tables used by the code.  This one will require
+	another pass in the future.
+

+
+	[truetype] Improve accuracy of normalization of short vectors.
+
+	Unit vector components are stored as 2.14 fixed-point numbers. In
+	order to calculate all 14 bits accurately, a short vector to be
+	normalized has to be upscaled to at least 14 bits before its length

+	were adopted.

+2013-01-12  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[truetype] Kill very old vector normalization hacks.
+
+	Back in the days, vector length calculations were not very accurate

+
+	[base] Improve trigonometric core.
+
+	FreeType used to rely on a 24-step iteration CORDIC algorithm to
+	calculate trigonometric functions and rotate vectors. It turns out
+	that once the vector is in the right half-plane, the initial rotation
+	by 63 degrees is not necessary. The algorithm is perfectly capable
+	to converge to any angle starting from the second 45 degree rotation.
+	This patch removes the first rotation and makes it a 23-step CORDIC
+	algorithm.
+
+	* src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro
+	values.
+	(ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial
+	rotation.
+

+2012-12-16  Werner Lemberg  <wl@gnu.org>
+
+	Various compiler warning fixes.
+
+	* include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use

+2012-12-15  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[base] Fix 11-year old bug.
+
+	Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has
+	always been slightly less than the correct value, which has been
+	given in the comment as a hexadecimal. As a result, vector lengths
+	were underestimated and rotated vectors were shortened.
+
+	* src/base/fttrigon.c (FT_TRIG_SCALE): Fix macro value.
+
+2012-12-15  Werner Lemberg  <wl@gnu.org>
+

+
+2012-12-10  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[truetype] Scale F_dot_P down.
+
+	The dot product between freeVector and projVector or cosine of
+	the angle between these FT_F2Dot14 unit vectors used to be scaled up
+	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
+	This patch scales the value down by 2^14 instead, which simplifies
+	its use throughout the bytecode interpreter.
+
+	This does not lead to the loss of precision because the lower bits
+	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
+	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
+	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
+	rounding and F_dot_P is assigned 0x26660000. The lower bits were
+	already lost while rounding the unit vector components.
+
+	Besides code simplification, this change can lead to better
+	performance when FT_MulDiv with the scaled-down F_dot_P is less
+	likely to use the costly 64-bit path. We are not changing the type
+	of F_dot_P to FT_F2Dot14 at this point.
+
+	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
+	bits and modify its use accordingly.
+	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
+	the use of F_dot_P field.
+	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
+	assignment of F_dot_P to its theoretical maximum in case we decide
+	to scale back its type later.

+
+	This is an improved version of a similar fix contained in the

+
+	  http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
+
+	which addresses various enhancements of the auto-hinter.  Without
+	properties to control a module's metadata it wasn't possible to
+	adapt the patches because everything was originally controlled by
+	environment variables which I consider not suitable in general.

+
+	The subpixel hinting patch contained the concept of an adjustable

+2012-06-18  Infinality  <infinality@infinality.net>
+
+	[truetype] Support subpixel hinting.
+
+	This is the large, famous `Infinality' patch to support ClearType
+	bytecode which has been available from
+	http://www.infinality.net/blog/ for some time, and which has been
+	refined over the last years.  While still experimental, it is now
+	mature enough to be included directly into FreeType.
+
+	Most of the code is based on the ClearType whitepaper written by
+	Greg Hitchcock
+
+	  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+
+	which gives a detailed overview of the necessary changes to the
+	Microsoft rasterizer so that older fonts are supported.  However, a
+	lot of details are still missing, and this patches provides a
+	framework to easily handle rendering issues down to the glyph level
+	of certain fonts.
+
+	Note that ClearType support is not completely implemented!  In
+	particular, full support for the options `compatible_widths',
+	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
+	instruction) is missing.
+
+	* src/truetype/ttsubpix.c: New file, providing code to handle
+	`tweaks', this is, rules for certain glyphs in certain fonts
+	(including wildcards) which need a special treatment.
+
+	* src/truetype/ttsubpix.h: New file, holding the tweaking rules.
+
+	* include/freetype/config/ftoption.h, src/devel/ftoption.h
+	(TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro.
+
+	* include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,

+
+	* src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include

+
+	[autofit] Return correct linear advance width values.
+
+	This was quite a subtle bug which accidentally showed up with glyph
+	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;
+	the first component, `E', has an advance width of 1366 font units,
+	while the advance width of the composite itself (which looks like
+	uppercase `E' with dieresis) is 1367 font units.  I think this is
+	actually a bug in the font itself, because there is no reason that
+	this glyph has not the same width as uppercase `E' without the
+	dieresis.  Anyway, it helped identify this problem.
+
+	Using the TrueType hinter, the correct value (1367) of `afii10023'
+	was returned, but the autohinter mysteriously returned 1366.
+
+	Digging in the code showed that the autohinter recursively calls
+	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
+	flag.  However, the `linearHoriAdvance' field is still returned as a
+	scaled value.  To avoid scaling twice, the old code in autofit reset
+	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to
+	work since FT_LOAD_NO_SCALE was in use, but it failed actually,
+	because `horiAdvance' is defined as the distance of the first
+	subglyph's phantom points, which in turn are initialized using the
+	advance width of the first subglyph.  And as the given example
+	shows, these widths can differ.
+
+	* src/autofit/afloader.c (af_loader_load_g): Temporarily set
+	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
+	values for the linear advance widths.

+	[truetype] Fix SSW instruction.

+	* src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.  For

+	this instruction.

+
+	Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
+	are renamed with `ft_' suffixes.
+
+	* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed

+	* src/base/ftobjs.c: Ditto.
+
+	* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
+	raccess_guess_rec, are moved to...
+	* include/freetype/internal/ftrfork.h: Here.
+
+	* include/freetype/internal/ftrfork.h:
+	FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
+	to replace raccess_guess_table[] in both of PIC and non-PIC
+	modes.
+	* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
+	by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
+
+	* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'

+
+	[autofit] Fix the inclusion of `aflatin2.h' in PIC file.
+
+	* src/autofit/afpic.c: Include `aflatin2.h' when

+	Unconditionally inclusion causes declared but unimplemented

+
+2012-01-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
+
+	* src/cff/cffpic.c: The declarations of
+	FT_Init_Class_cff_cmap_encoding_class_rec() and
+	FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
+	They can be obtained by the inclusion of cffcmap.h.
+	cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
+	FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
+
+2012-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix redundant declaration warning in PIC mode.
+
+	Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
+	designed to declare xxx_pic_{free,init} by themselves.
+	Because these macros are used at the end of the module
+	interface (e.g. ttdriver.c) and the wrapper source to build
+	a module as a single object (e.g. truetype.c) includes
+	the PIC file (e.g. ttpic.c) before the module interface,
+	these macros are expanded AFTER xxx_pic_{free,init} body
+	when the modules are built as single object.
+	The declaration after the implementation causes the redundant
+	declaration warnings, so the declarations are moved to module
+	PIC headers (e.g. ttpic.h).  Separating to other header files
+	are needed for multi build.
+
+	* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
+	Remove class_##_pic_free and class_##_pic_init declarations.
+	* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
+	FT_DEFINE_MODULE): Ditto.
+
+	* src/base/basepic.h: Insert a comment and fix coding style.
+	* src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
+	init}.
+	* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
+	* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
+	init}.
+	* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
+	init}.
+	* src/raster/rastpic.h: Declare
+	ft_raster{1,5}_renderer_class_pic_{free,init}
+	* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
+	* src/smooth/ftspic.h: Declare
+	ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
+	* src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
+
+2012-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

+
+2012-01-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[base] Fix a dereference of uninitialized variable in PIC mode.
+
+	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
+	set before dereferring to obtain `library'.  The initialization
+	of `clazz', `glyph', `library' and NULL pointer check are
+	reordered to minimize PIC conditionals.
+
+2012-01-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[base] Insert explicit cast for GCC 4.6 in PIC mode.
+
+	* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
+	configuration, FT_DEFAULT_MODULES_GET returns
+	FT_Module_Class** pointer, GCC 4.6 warns that
+	const FT_Module_Class* const* variable is warned as
+	inappropriate to store it.  To calm it, explicit cast is
+	inserted.  Also `library' is checked to prevent the NULL
+	pointer dereference in FT_DEFAULT_MODULES_GET.
+
+2012-01-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
+
+	Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
+	take no arguments but derefer the variable named `library'
+	internally.
+
+	* src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
+	set it if non-NULL driver is passed.
+	* src/truetype/ttdriver.c (tt_get_interface): Ditto.
+
+	* src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'

+
+2012-01-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

+
+2011-12-10  Werner Lemberg  <wl@gnu.org>
+
+	Add some variable initializations.

+
+2011-12-02  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
+
+	Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
+	was a configurable macro to disable Carbon-dependent code.  Because
+	now configure script sets DARWIN_NO_CARBON by default and disables
+	Darwin & Carbon-dependent codes, these macros can be unified.
+	FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
+	(defined by default) is removed, because DARWIN_NO_CARBON violates
+	FT_XXX naming convention of public macros, and a macro configured by
+	default is not portable for the building without configure (e.g.
+	make devel).
+
+	* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
+	old Mac font support is requested and Carbon is available.
+	* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
+	for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
+	requested.

+
+	[apinames] Fix the overflow of signed integer hash.
+
+	* src/tools/apinames.c (names_add): Change the type of `h' from

+

+
+	[bdf] Fix Savannah bug #34896.
+
+	ENCODING now covers the whole Unicode range.
+
+	Note, however, that this change is quite expensive since it
+	increases the size of three arrays by almost 400kByte in total.  The
+	right fix is to replace the logic with something smarter.
+	Additionally, there exist very old BDFs for three-byte CCCII
+	encoding which exceeds the range of Unicode (another reason to have
+	a smarter logic).
+
+	* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'

+
+	Slightly improve LZW_CLEAR handling.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
+	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
+	handled as clear codes.  This also re-sets old_code and old_char to
+	predictable values, which is a little better than using `random'
+	ones if the code following LZW_CLEAR is invalid.
+
+2011-09-11  Tomas Hoger  <thoger@redhat.com>
+
+	Add explicit LZW decompression stack size limit.
+
+	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
+	constructed correctly.  It's even less than that, see e.g.
+	libarchive code comment for a better size upper bound:
+
+	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
+
+	This patch adds explicit stack size limit, enforced when stack is
+	realloced.
+
+	An alternative is to ensure that code < state->prefix[code - 256]
+	when traversing prefix table.  Such check is less efficient and
+	should not be required if prefix table is constructed correctly in
+	the first place.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
+
+2011-09-11  Tomas Hoger  <thoger@redhat.com>
+
+	Protect against loops in the prefix table.
+
+	LZW decompressor did not sufficiently check codes read from the
+	input LZW stream.  A specially-crafted or corrupted input could
+	create a loop in the prefix table, which leads to memory usage
+	spikes, as there's no decompression stack size limit.
+
+	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
+	code in valid LZW stream must be 0..255.
+	<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
+	code > free_ent is invalid.

+
+	[ftstroke] Major revision.
+
+	The main problems
+	-----------------
+
+	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
+	    joins (not bevel joins) were generated.  Indeed, the meanings of
+	    `miter' and `bevel' were incorrectly reversed (consistently) in
+	    both the code and comments.
+
+	  o The way bevel joins were constructed (whether specified
+	    explicitly, or created as a result of exceeding the miter limit)
+	    did not match what is required for stroked text in PostScript or
+	    PDF.
+
+	The main fixes
+	--------------
+
+	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+
+	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
+	    introduced to support PostScript and PDF miter joins.
+
+	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
+	    alias for FT_STROKER_LINEJOIN_MITER.
+
+	Additionally, a variety of stroking errors have been fixed.  These
+	would cause various artifacts (including points `at infinity'),
+	especially when stroking poor quality fonts.
+
+	See
+
+	  http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
+
+	for example documents.  The FreeType stroker now produces results
+	very similar to that produced by GhostScript and Distiller for these
+	fonts.
+
+	Other problems
+	--------------
+
+	The following problems have been resolved:
+
+	  o Inside corners could be generated incorrectly.  Intersecting the
+	    inside corner could cause a missing triangular area and other
+	    effects.
+
+	    The intersection point can only be used if the join is between
+	    two lines and both lines are long enough.  The `optimization'
+	    condition in `ft_stroker_inside' has been corrected; this
+	    requires the line length to be passed into various functions and
+	    stored in `FT_StrokerRec'.
+
+	  o Incorrect cubic curves could be generated.  The angle
+	    calculations in `FT_Stroker_CubicTo' have been corrected to
+	    handle the case of the curve crossing the +/-PI direction.
+
+	  o If the border radius was greater than the radius of curvature of
+	    a curve, then the negative sector would end up outside (not
+	    inside) the border.  This situation is now recognized and the
+	    negative sector is circumnavigated in the opposite direction.
+	    (If round line joins are being used, this code is disabled
+	    because the line join will always cover the negative sector.)
+
+	  o When a curve is split, the arcs may not join smoothly (especially
+	    if the curve turns sharply back on itself).  Changes in
+	    direction between adjacent arcs were not handled.  A round
+	    corner is now added if the deviation from one arc to the next is
+	    greater than a suitable threshold.
+
+	  o The current direction wasn't retained if a the outline contained
+	    a zero length lineto or a curve that was determined to be
+	    `basically a point'.  This could cause a spurious join to be
+	    added.
+
+	  o Cubics with close control points could be mishandled.  All eight
+	    cases are now distinguished correctly.
+
+	Other improvements
+	------------------
+
+	o Borders for cubic curves could be too `flat'.
+	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
+	  this.
+
+	o The handling and use of movable points has been simplified a
+	  little.
+
+	o Various values are now computed only if the results are actually
+	  needed.
+
+	o The directions of the outer and inner borders have been swapped,
+	  as recommended by Graham Asher.

+
+2011-01-13  Werner Lemberg  <wl@gnu.org>
+
+	[raster] Handle drop-outs at glyph borders according to Microsoft.
+
+	If a drop-out rule would switch on a pixel outside of the glyph's

+	undocumented feature, but some fonts like `Helvetica Neue LT Com 65
+	Medium' heavily rely on it.
+
+	Thanks to Greg Hitchcock who explained this behaviour.

+
+	[cache] Fix Savannah bug #31923, patch drafted by Harsha.
+
+	When a node comparator changes the cached nodes during the
+	search of a node matching with queried properties, the
+	pointers obtained before the function should be updated to
+	prevent the dereference to freed or reallocated nodes.
+	To minimize the rescan of the linked list, the update is
+	executed when the comparator notifies the change of cached
+	nodes. This change depends previous change:
+	38b272ffbbdaae276d636aec4ef84af407d16181
+
+	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
+	top node if the cached nodes are changed.
+	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Notice if a cache query induced the node list change.
+
+	Some node comparators (comparing the cache node contents and the
+	properties specified by the query) can flush the cache node to
+	prevent the cache inflation.  The change may invalidate the pointers
+	to the node obtained before the node comparison, so it should be
+	noticed to the caller.  The problem caused by the cache node
+	changing is reported by Harsha, see Savannah bug #31923.
+
+	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
+	`FT_Bool* list_changed' to indicate the change of the cached nodes
+	to the caller.
+	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
+	`_list_changed'.
+	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
+	and update it when `FTC_Manager_FlushN' flushes any nodes.
+
+	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
+	FTC_Node_CompareFunc type.
+	(ftc_gnode_compare): Ditto.
+
+	* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
+	TRUE/FALSE macros.
+	(ftc_basic_gnode_compare_faceid): New argument `FT_Bool*

+	is always FALSE).
+
+	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
+	TRUE/FALSE macros.
+	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
+	indicate the change of the cache nodes (anyway, it is always FALSE).
+	(ftc_cmap_node_remove_faceid): Ditto.
+
+	* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
+	`FTC_CACHE_TRYLOOP_END', because the result is not needed.
+	(FTC_Cache_Lookup): Watch the change of the cache nodes by
+	`list_changed'.
+	(FTC_Cache_RemoveFaceID): Ditto.
+
+	* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
+	TRUE/FALSE macros.
+	(ftc_gnode_compare): New argument `FT_Bool* list_changed' to
+	indicate the change of the cache nodes (anyway, it is always FALSE).
+	(FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
+	passed to `ftc_gnode_compare'.
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+
+	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
+	list_changed' to indicate the change of the cache nodes, anyway.  It
+	is updated by `FTC_CACHE_TRYLOOP'.
+	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
+	passed to `ftc_snode_compare'.
+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
+
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
+	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc
+	prototype.
+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
+	`cache' is not used by its child `ftc_gnode_compare'.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Deduplicate the code to get the top node by a hash.
+
+	There are several duplicated code fragments getting the top node
+	from a cache by a given hash, like:
+
+	    idx = hash & cache->mask;
+	    if ( idx < cache->p )
+	      idx = hash & ( cache->mask * 2 + 1 );
+	    pnode = cache->buckets + idx;
+
+	To remove duplication, a cpp-macro to do same work
+	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined
+	configuration, non-`ftc_get_top_node_for_hash' is also introduced.
+
+	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
+	and implement inlined version.
+	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
+	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined

+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] inline-specific functions are conditionalized.
+
+	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
+	inlined configuration.  This function is a thin wrapper of
+	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
+	`nodecmp' argument).  Under non-inlined configuration,
+	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
+	`FTC_Cache->clazz.node_compare'.
+
+	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
+	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
+	`ftc_snode_compare'.
+	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
+
+2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[cache] Correct a type mismatch under non-inlined config.
+
+	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
+	takes the node via a pointer `FTC_Node*', differently from cpp-macro
+	`FTC_CACHE_LOOKUP_CMP'.
+

+
+	* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
+
+	SYSTEM_ZLIB is used to switch the builtin zlib source

+2010-12-25  Harsha  <mm.harsha@gmail.com>
+
+	Apply Savannah patch #7422.
+
+	If we encounter a space in a string then the sbit buffer is NULL,
+	height and width are 0s.  So the check in ftc_snode_compare will
+	always pass for spaces (comparison with 255).  Here the comments
+	above the condition are proper but the implementation is not.  When
+	we create an snode I think it is the proper way to initialize the
+	width to 255 and then put a check for being equal to 255 in snode
+	compare function.
+
+	* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
+	value 255.
+	(ftc_snode_compare): Fix condition.

+
+	[cache] Change the hash types to FT_PtrDist.
+
+	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
+	variables are inappropriate to calculate hash values
+	from the memory address (64-bit).  The hash variables
+	are extended from FT_ULong to FT_PtrDist and new

+	values on 16-bit memory platforms are changed, but

+	[raccess] Skip unrequired resource access rules by Darwin VFS.
+
+	When a resource fork access rule by Darwin VFS could open the
+	resource fork but no font is found in it, the rest of rules
+	by Darwin VFS are skipped.  It reduces the warnings of the
+	deprecated resource fork access method by recent Darwin kernel.

+
+	* src/base/ftobjs.c (load_face_in_embedded_rfork):
+	When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
+	means that the file is possible to be `fopen'-ed but zero-sized.
+	Also there is a case that the resource fork is not zero-sized,
+	but no supported font exists in it.  If a rule by Darwin VFS
+	falls into such cases, there is no need to try other Darwin VFS
+	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.
+	If it is TRUE, the Darwin VFS rules are skipped.

+
+	[raccess] Grouping resource access rules based on Darwin VFS.
+
+	MacOS X/Darwin kernel supports a few tricky methods to access

+	fork accessor tries all possible methods to support all kernels.
+	But if a method could open a resource fork but no font is found,
+	there is no need to try other methods older than tested method.
+	To determine whether the rule index is for Darwin VFS, a local
+	function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
+	To use this function in ftobjs.c etc but it should be inlined,
+	it is exposed by ftbase.h.
+
+	* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify

+	(raccess_guess_rec): New structure to bind the rule function and

+	(FT_Raccess_Guess): The list of the rule functions is replaced by
+	(raccess_guess_table): This.  This is exposed to be used by other
+	intra module functions.
+	(raccess_rule_by_darwin_vfs): A function to return a boolean
+	if the rule specified by the rule index is based on Darwin VFS.

+	FT_GlyphZoneRec size->twilight to be freed.  If duplicated,
+	`FT_FREE' erases the duplicated pointers only and leave original
+	pointers.  They can cause the double-free crash when the burst
+	errors occur in TrueType interpreter and `free_buffer_in_size' is
+	invoked repeatedly.
+
+2010-09-15  Werner Lemberg  <wl@gnu.org>
+
+	Make bytecode debugging with FontForge work again.

+
+2010-09-14  Werner Lemberg  <wl@gnu.org>

+
+	Ignore the environmental setting of LIBTOOL.
+	Patch is suggested by Adrian Bunk, to prevent unexpected
+	reflection of environmental LIBTOOL.  See:
+	http://savannah.nongnu.org/patch/?7290
+
+	* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
+	$(FT_LIBTOOL_DIR)/libtool.  FT_LIBTOOL_DIR is set to $(BUILD_DIR)
+	by default.
+	* configure: When configured for the building out of source tee,
+	FT_LIBTOOL_DIR is set to $(OBJ_DIR).

+
+	[truetype] Prevent bytecode reuse after the interpretation error.
+
+	* src/truetype/ttinterp.c (free_buffer_in_size): New function to
+	free the buffer allocated during the interpretation of this glyph.
+	(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
+	an error occurs in the bytecode interpretation.  The interpretation
+	of invalid bytecode may break the function definitions and referring
+	them in later interpretation is danger.  By unsetting these flags,
+	`fpgm' and `prep' tables are executed again in next interpretation.
+
+	This fixes Savannah bug #30798, reported by Robert Święcki.

+
+	Force hinting when the font lacks its familyname.
+
+	In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt

+
+2010-05-10  Ken Sharp  <ken.sharp@artifex.com>
+
+	[psaux] Fix Savannah bug #29846.
+
+	Previously we discovered fonts which used `setcurrentpoint' to set
+	the initial point of a contour to 0,0.  This caused FreeType to
+	raise an error, because the `setcurrentpoint' operator is only
+	supposed to be used with the results from an OtherSubr subroutine.
+
+	This was fixed by simply ignoring the error and carrying on.
+
+	Now we have found a font which uses setcurrentpoint to actually
+	establish a non-zero point for a contour during the course of a
+	glyph program.  FWIW, these files may be produced by an application
+	called `Intaglio' on the Mac, when converting TrueType fonts to
+	Type 1.
+
+	The fix allows the new invalid behaviour, the old invalid behaviour
+	and real proper usage of the operator to work the same way as Adobe
+	interpreters apparently do.
+
+	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
+	`setcurrentpoint' use the top two elements of the stack to establish
+	unconditionally the current x and y coordinates.
+
+	Make the `flex' subroutine handling (OtherSubr 0) put the current
+	x,y coordinates onto the stack, instead of two dummy uninitialised
+	values.
+
+2010-04-14  Ken Sharp  <ken.sharp@artifex.com>
+
+	[psaux] Fix Savannah bug #29444.

+
+2010-04-05  Werner Lemberg  <wl@gnu.org>

+	[otvalid] Fix a naming convention conflicting with ftvalid.
+
+	Some prototypes in ftvalid.h use `valid' for the variables
+	typed as FT_Validator.  Their implementations in src/base/
+	ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
+
+	Some macros in otvcommn.h assume the exist of the variable
+	`valid' typed as OTV_Validator in the caller.
+
+	Mixing these two conventions cause invalid pointer conversion
+	and unexpected SEGV in longjmp.  To prevent it, all variables
+	typed as OTV_Validator are renamed to `otvalid'.

+	[pcf] Fix Savannah bug #43774.
+
+	Work around `features' of X11's `pcfWriteFont' and `pcfReadFont'

+
+	[autofit] Better fix for conversion specifiers in debug messages.
+
+	Using `%ld' for pointer differences causes warnings on 32bit
+	platforms.  The correct type would be (the relatively new) `%td',
+	however, this is missing on some important platforms.
+
+	This patch improves the change from 2014-11-28.
+
+	* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast.  Our
+	pointer differences are always sufficiently small.
+	(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
+	af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

+
+2014-12-02  Werner Lemberg  <wl@gnu.org>
+
+	[docmaker] Always handle `<Order>' section elements.
+
+	Previously, those elements were handled only for sections present in
+	a `<Sections>' chapter element.
+
+	* src/tools/docmaker/content.py (ContentProcessor::finish):
+	Implement it.
+
+2014-12-02  Werner Lemberg  <wl@gnu.org>

+
+	* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it

+
+	* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit

+
+2014-11-29  Werner Lemberg  <wl@gnu.org>
+
+	[docmaker] Allow empty lines in `<Order>' blocks.
+
+	Before this patch, the suggested order of entries stopped at the
+	first empty line.
+
+	Obviously, nobody noticed that this problem caused a much reduced
+	set of links in the `Synopsis' sections; in particular, the
+	`<Order>' blocks contain a lot of entries that wouldn't be listed
+	otherwise...
+
+	* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
+	New function to iterate over all items.
+	(DocSection::process): Use it.

+
+	* src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>'
+	elements, use CSS descendants (of class `section') to format the
+	data.
+
+	Also remove redundant <p> and <br> elements, replacing them with
+	proper CSS.
+
+	Globally reduce page width to 75%.
+
+	(block_header): Rename <div> class to `section'.
+
+2014-11-29  Werner Lemberg  <wl@gnu.org>
+
+	[docmaker] Add `top' links after blocks.
+

+
+2014-11-27  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
+
+	For `Index' and `TOC' links, we now simply use the `text-align' CSS
+	property of `<td>' to enforce flush-left and flush-right,
+	eliminating the hack with an empty, full-width `<td>' element
+	inbetween.
+
+	The change also enforces the same (smaller) size for all index and
+	TOC links.

+
+	Don't cast cmap init function pointers to an incompatible type.
+
+	Without this patch, the number of parameters between declaration and
+	the real signature differs.  Calling such a function results in
+	undefined behavior.
+
+	  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
+	    6.5.2.2 Function calls
+	      9 If the function is defined with a type that is not
+	        compatible with the type (of the expression) pointed to by
+	        the expression that denotes the called function, the
+	        behavior is undefined.
+
+	On certain platforms (c -> js with emscripten) this causes
+	termination of execution or invalid calls because in the emscripten
+	implementation, function pointers of different types are stored in
+	different pointer arrays.  Incorrect pointer type here results in
+	indexing of an incorrect array.

+
+	[autofit] Fix Savannah bug #42148.
+
+	The adaptation of the cjk auto-hinter module to blue stringsets in
+	2013-08-25 had three severe bugs.  Mea culpa.
+
+	1. Contrary to the latin auto-hinter, characters for reference and
+	   overshoot values of a blue zone are specified separately.  Due to
+	   the screwed-up change it didn't work at all.
+
+	2. A boolean comparison was erroneously replaced with a cast,
+	   causing invalid results with the `^' operator later on.  The
+	   visual artifact caused by this problem is the topic of the bug
+	   report.
+
+	3. Two flag values were inverted, causing incorrect assignment of
+	   reference and overshoot values.
+
+	* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
+	syntax to have both reference and overshoot characters in a single
+	string.  This is error #1.
+	Add extensive comments.
+
+	* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
+	longer used.
+	(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
+	This is error #3.
+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+	* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
+	Use character `|' to separate characters for reference and overshoot
+	values.
+	Improve tracing messages, synchronizing them with the latin
+	auto-hinter.
+	(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
+	This is error #2.
+	(af_cjk_align_linked_edge): Add tracing message.
+

+
+	[autofit] Redesign the recognition algorithm of strong points.
+
+	In particular, local extrema without horizontal or vertical segments
+	are better recognized:
+
+	  + A                + D
+	   \                /
+	    \              /
+	     \            /
+	      \          /
+	       \        + C
+	        \    /
+	       B +/
+
+	If the distances AB and CD are large, point B wasn't previously
+	detected as an extremum since the `ft_corner_is_flat' function
+	`swallowed' BC regardless of its direction, tagging point B as weak.
+	The next iteration started at B and made `ft_corner_is_flat' swallow
+	point C, tagging it as weak also, et voilà.
+
+	To improve that, another pass gets now performed before calling
+	`ft_corner_is_flat' to improve the `topology' of an outline: A
+	sequence of non-horizontal or non-vertical vectors that point into
+	the same quadrant are handled as a single, large vector.
+
+	Additionally, distances of near points are now accumulated, which
+	makes the auto-hinter handle them as if they were prepended to the
+	next non-near vector.
+
+	This generally improves the auto-hinter's rendering results.
+
+	* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.
+
+	* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
+	`AF_FLAG_NEAR'.
+

+
+	[autofit] Improve scoring algorithm for identifying stems.
+
+	Problem reported by Karsten Lücke <karsten.luecke@kltf.de>.
+
+	The new algorithm takes care of the width of stems: If the distance
+	between two segments is larger than the largest stem width, the
+	demerits quickly increase for larger distances.  This improves
+	hinting of slanted fonts (especially if the inner parts of serifs
+	have non-horizontal `shoulders'), avoiding false stem links.
+
+	* src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest

+
+2014-03-04  Werner Lemberg  <wl@gnu.org>
+
+	Minor fix for `make devel'.
+
+	* builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use
+	pkg-config for bzip2 since not all GNU/Linux distributions have
+	`bzip2.pc' (and the header file `bzlib.h' is located in /usr/include
+	normally).
+
+2014-03-04  Sean McBride  <sean@rogue-research.com>

+
+2014-03-03  Werner Lemberg  <wl@gnu.org>
+
+	Rewrite library option handling in `configure'.
+

+	  now the default.
+
+	o First use `pkg-config' for library detection, then fall back to
+	  other tests.
+
+	* builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
+	--with-harfbuzz): Rewrite.

+
+2014-03-01  Werner Lemberg  <wl@gnu.org>
+
+	Avoid `long long' warnings with older gcc compilers.
+	Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.
+
+	* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
+	versions < 4.6.  This is especially needed for Max OS X since this
+	OS runs a gcc variant (or emulation) based on version 4.2.1.
+
+2014-03-01  Werner Lemberg  <wl@gnu.org>
+
+	* docs/INSTALL.CROSS: Revised and updated.
+
+2014-03-01  Werner Lemberg  <wl@gnu.org>

+
+	This is a generated file at build time, not configure time.
+
+	* builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...
+	(CLEAN): This variable.
+
+2014-03-01  Werner Lemberg  <wl@gnu.org>

+
+2014-02-28  Dave Arnold  <darnold@adobe.com>
+
+	[cff] Fix Savannah bug #41697, part 2.
+
+	* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
+	cf2_initGlobalRegionBuffer): It is possible for a charstring to call
+	a subroutine if no subroutines exist.  This is an error but should
+	not trigger an assert.  Split the assert to account for this.
+
+2014-02-28  Dave Arnold  <darnold@adobe.com>
+
+	[cff] Fix Savannah bug #41697, part 1.
+
+	* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
+	invalid.  In this case, it is not safe to use the length of
+	`hStemHintArray'; the exception has already been recorded in
+	`hintMask'.
+
+2014-02-26  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt] Fix Savannah bug #41696.

+	* src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.
+
+2014-02-26  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix Savannah bug #41692.
+
+	bdflib puts data from the input stream into a buffer in chunks of
+	1024 bytes.  The data itself gets then parsed line by line, simply
+	increasing the current pointer into the buffer; if the search for
+	the final newline character exceeds the buffer size, more data gets
+	read.
+
+	However, in case the current line's end is very near to the buffer
+	end, and the keyword to compare with is longer than the current
+	line's length, an out-of-bounds read might happen since `memcmp'
+	doesn't stop properly at the string end.
+
+	* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
+	stop at string ends.
+
+2014-02-17  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

+
+	[autofit] Minor fixes for `afblue.pl'.
+

+
+	[autofit] Fix Indic scripts.
+
+	Split the single, incorrect Indic entry into separate scripts so
+	that the covered ranges are the same: Bengali, Devanagari, Gujarati,
+	Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
+	Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove
+	entries for Meetei Mayek and Sharada – the Unicode ranges were
+	incorrect (and nobody has complained about that), fonts are scarce
+	for those scripts, and the Indic auto-hinter support is rudimentary
+	anyways.
+
+	* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
+	AF_CONFIG_OPTION_CJK.
+
+	* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
+	Use it, together with AF_CONFIG_OPTION_INDIC and
+	AF_CONFIG_OPTION_CJK, to update.
+
+	* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
+	[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
+	Sort entries by tags.

+
+	[autofit] Thinko.
+
+	* src/autofit/hbshim.c (af_get_char_index): Similar to
+	`af_get_coverage', reject glyphs which are not substituted.
+
+2014-01-03  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Fix handling of default coverages.
+
+	With this commit, the implementation of coverage handling is
+	completed.
+
+	* src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to
+	do.
+	Reject coverages which don't contain appropriate glyphs for blue
+	zones.
+
+2014-01-03  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Fix handling of default coverages.

+
+	* src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add

+
+	[autofit] Remove some styles.
+
+	* src/autofit/afcover.h: Remove coverages for alternative fractions,
+	denominators, numerators, and fractions.

+
+2014-01-01  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Add more styles.
+
+	* src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New
+	auxiliary macros; use them to define styles for Cyrillic, Greek, and
+	Latin.
+
+	* src/autofit/afcover.h: Remove coverage for oldstyle figures.
+	Since those digits are used in combination with ordinary letters, it
+	makes no sense to handle them separately.
+
+	* src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
+	`options' parameter to 4 bits.
+
+2014-01-01  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Fix style assignments to glyphs.
+
+	* src/autofit/hbshim.c (af_get_coverage)

+	src/autofit/aflatin.c: Updated.
+
+2013-12-30  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Don't combine multiple features into one set.
+
+	Combining them, as originally envisioned, would lead to much more
+	complicated code, as investigations have shown meanwhile.  The major
+	drawback is that we run out of available style slots much earlier.
+	However, this is only a theoretical issue since we don't support a
+	large number of scripts currently.
+
+	* src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with
+	a single-element `COVERAGE' macro, sort the elements by the feature
+	tags, and add entry for `ruby'.
+
+	* src/autofit/aftypes.h: Updated.
+	* src/autofit/hbshim.c: Updated.
+
+2013-12-28  Werner Lemberg  <wl@gnu.org>

+	unconditionally.
+
+2013-12-28  Werner Lemberg  <wl@gnu.org>

+	* src/autofit/hbshim.h: Updated.

+
+	[autofit] Use `global' HarfBuzz font object.
+
+	We now use `hb_font' instead of `hb_face' since yet-to-come changes

+
+	[ftrfork] Fix the face order difference between POSIX and Carbon.
+
+	The fragmented resources in Suitcase and .dfont should be reordered
+	when `POST' resource for Type1 is being restored, but reordering of
+	sfnt resources induces the different face order.  Now the ordering
+	is restricted to `POST' resource only, to prevent the different
+	order issue (e.g. the face index in the fontconfig cache generated
+	with Carbon framework is incompatible with that by FreeType 2
+	without Carbon framework.)  Found by Khaled Hosny and Hin-Tak Leung.

+2013-12-21  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Introduce `coverages'.
+
+	Coverages are the interface to the HarfBuzz library to access
+	OpenType features for handling glyphs not addressable by the cmap.
+
+	Right now, compilation of HarfBuzz is only added to the development
+	build.  A solution for standard build mode will be delayed until
+	HarfBuzz gets split into two libraries to avoid mutual dependencies
+	between FreeType and HarfBuzz.
+
+	Note that this is only a first step in handling coverages, basically
+	providing the framework only.  Code for handling selected OpenType
+	features (this is, actually using the data in `afcover.h') will
+	follow.
+
+	* devel/ftoption.h, include/config/ftoption.h

+
+2013-12-21  Werner Lemberg  <wl@gnu.org>

+2013-11-13  Werner Lemberg  <wl@gnu.org>
+
+	Simplify header file hierarchy.
+
+	This large patch changes the header file directory layout from
+	`include/freetype/...' to `include/...', effectively removing one
+	level.  Since the file `ft2build.h' is also located in `include'
+	(and it stays there even after installation), all FreeType header
+	files are now in a single directory.
+
+	Applications that use (a) `freetype-config' or FreeType's
+	`pkg-config' file to get the include directory for the compiler, and
+	(b) the documented way for header inclusion like
+
+	  #include <ft2build.h>

+
+	Two benefits: The allocated FDEF (and IDEF) array gets slightly

+
+	Fortunately, no changes to FontForge are necessary – this is the

+
+	When using `ADD' with an immediate operand, the instruction is

+
+	* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
+
+	Note that the old code avoided using a region of the piecewise

+	different section of the function, which produced a different,
+	incorrect amount of darkening.

+
+2013-10-02  Dave Arnold  <darnold@adobe.com>
+
+	* src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount.
+
+	This line was lost in commit 89ca1fd6 (from 2013-06-25).  The effect
+	is to use a previous darkening amount when producing an unhinted,
+	unscaled outline.  This can cause autohint samples in ftgrid and
+	ftview to be based on darkened CFF outlines instead of unhinted,
+	undarkened ones.
+
+2013-09-29  Dave Arnold  <darnold@adobe.com>
+
+	Fix Savannah bug #39295.
+
+	The bug was caused by switching to the initial hintmap (the one in
+	effect when `moveto' executes) just before drawing the final element
+	in the charstring.  This ensured that the path was closed (in both
+	Character Space and Device Space).  But if the final element was a
+	curve and if the final hintmap was different enough from the initial
+	one, then the curve was visibly distorted.
+
+	The first part of the fix is to draw the final curve using the final
+	hintmap as specified by the charstring.  This corrects the
+	distortion but does not ensure closing in Device Space.  It may
+	require the rasterizer to automatically generate an extra closing
+	line.  Depending on the hintmap differences, this line could be from
+	zero to a couple pixels in length.
+
+	The second part of the fix covers the case where the charstring
+	subpath is closed with an explicit line.  We now modify that line's
+	end point to avoid the distortion.
+
+	Some glyphs in the bug report font (TexGyreHeros-Regular) that show
+	the change are:
+
+	  25ppem    S (98)
+	  24ppem    eight (52)
+	  25.5ppem  p (85)
+
+	Curves at the *end* of a subpath are no longer distorted.  However,
+	some of these glyphs have bad hint substitutions in the middle of a
+	subpath, and these are not affected.
+
+	The patch has been tested with a set of 106 fonts that shipped with
+	Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
+	Google Fonts.  There are 1.5 million glyphs, of which some 20k are
+	changed with the fix.  A sampling of a few hundred of these changes
+	have been examined more closely, and the changes look good (or at
+	least acceptable).
+
+	* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
+	to indicate that we synthesize a closepath line.
+
+	* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
+	(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
+	`lineto' operator) and adjust hint zone.
+	For synthesized closing lines, use end point in first hint zone.
+	(cf2_glyphpath_lineTo): Take care of synthesized closing lines.  In
+	particular, shift the detection of zero-length lines from character
+	space to device space.
+	(cf2_glyphpath_closeOpenPath): Remove assertion.
+	Updated.

+
+2013-08-29  Werner Lemberg  <wl@gnu.org>
+            Behdad Esfahbod  <behdad@google.com>
+
+	Implement support for WOFF containers.
+
+	We simply synthesize a SFNT from the WOFF, create a memory stream
+	for the new data, and load the SFNT as usual.
+
+	Does NOT add any API to access WOFF metadata or private blocks.
+
+	* include/freetype/internal/tttypes.h (WOFF_HeaderRec,

+
+	* src/sfnt/ttload.c (tt_face_load_font_dir): Fix sign typos.
+
+2013-08-27  Behdad Esfahbod  <behdad@google.com>
+
+	FT_Open_Face: Improve external stream handling.
+
+	If the font's `clazz->init_face' function wants to swap to new
+	stream, handling of whether original stream was external could
+	result to either memory leak or double free.  Mark externality into
+	face flags before calling `init_face' such that the clazz can handle
+	external streams properly.
+
+	* src/base/ftobjs.c (FT_Open_Face): Move code to set
+	FT_FACE_FLAG_EXTERNAL_STREAM to...
+	(open_face): This function.
+
+2013-08-27  Werner Lemberg  <wl@gnu.org>

+
+2013-08-26  Werner Lemberg  <wl@gnu.org>
+
+	Better tracing of loaded glyphs.
+
+	Previously, the loading of a glyph was traced at level 4, if at all.
+	With this change, all font loading routines emit a tracing message
+	at level 1, making it easier to select tracing output (for example
+	using F2_DEBUG="any:1 afhints:7 aflatin:7").
+
+	* src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message.
+	* src/cff/cffdrivr.c (cff_glyph_load): Ditto.

+	(AF_CJK_BLUE_TYPE_*): Removed.
+	(af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with
+	AF_BLUE_STRING_MAX_LEN.
+	Change loops to use offsets (in file `afblue.h') into the new arrays
+	`af_blue_stringsets' and `af_blue_strings' (in file `afblue.c').
+	Instead of three dimensions (as used in the old blue string array)
+	we now use properties to do the same, saving one loop nesting level.
+
+	* src/autofit/afcjk.h: Remove old enumeration values superseded by
+	the new data in `afblue.h'.
+	(AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE,
+	AF_CJK_IS_RIGHT_BLUE): New macros, to be used in
+	`af_cjk_metrics_init_blues'.
+	(AF_CJK_BLUE_IS_RIGHT): Remove this now redundant enum value.
+	(AF_CJK_BLUE_IS_TOP): Renamed to...
+	(AF_CJK_BLUE_TOP): This.

+	(af_latin_metrics_init_blues): Replace AF_LATIN_MAX_TEST_CHARACTERS
+	with AF_BLUE_STRING_MAX_LEN.
+	Change loops to use offsets (in file `afblue.h') into the new arrays

+
+2013-08-25  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Introduce data file for blue strings.
+
+	The idea is to have a central file which gets processed by a Perl
+	script to create proper `.c' and `.h' files using templates.  There
+	are two other reasons to do that:
+
+	  . The data file should be easily readable.  We use UTF-8 encoding
+	    which then gets converted to single bytes.
+
+	  . Since the number of supported scripts will increase soon, the
+	    current usage of blue string arrays is a waste of space.  Using
+	    the Perl script it is possible to imitate jagged arrays,
+	    defining enumeration constants as offsets into the arrays.
+
+	This commit only adds files without changing any functionality.
+
+	* src/autofit/afblue.dat: New data file.
+	* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
+
+	* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files
+	for...
+	* src/autofit/afblue.c, src/autofit/afblue.c: New source files.
+	To avoid a dependency on Perl, we add them too.

+
+	Fix Savannah bug #39702.
+
+	* src/cff/cffload.c (cff_index_get_pointers): Check for `cur_offset

+	possible for easier maintenance.
+
+2013-08-05  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Improve handling of `near' points.
+
+	Points which are very near to each other are now marked as such.
+	The `weak' flag is then computed by using the `in' vector of the
+	first and the `out' vector of the last point of a group of near
+	points.
+
+	For example, this fixes the rendering of glyph `Oslash' in
+	`Roboto-Thin.ttf'.
+
+	* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.
+
+	* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
+	the heuristic value `near_limit' to decide whether the current point
+	is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
+	Store good `in' vector (of last non-near point) in
+	`last_good_in_{x,y}' and use it as an argument to
+	`ft_corner_is_flat' if necessary.
+
+2013-08-02  Werner Lemberg  <wl@gnu.org>

+
+	[autofit] Introduce `writing systems'.
+
+	This patch adds a new top level to the auto-hinter's script class

+
+	Speed up ARMv7 support.
+
+	When building for ARMv7 with thumb2 instructions, the optimized
+	`FT_MulFix_arm' assembly routine was not being used.
+
+	The reason for this is in the `ftconfig.h' header, namely:
+
+	- The assembly routine uses the `smull' instruction which is not
+	  available when generating Thumb-1 machine code.  It is available
+	  in Thumb-2 mode, though.
+
+	- The header was written a long time ago before Thumb-2 became
+	  widely popular (e.g. with Android).  So it simply doesn't use the
+	  assembly routine if the `__thumb__' built-in macro is defined.
+
+	- When compiling in Thumb-2 mode, the compiler will define both
+	  `__thumb__' and `__thumb2__'.
+
+	By checking for `(__thumb2__ || !__thumb__)', we ensure that the
+	assembly routine is only avoided when generating Thumb-1 code.
+
+	Given that this is performance-sensitive function, this improves
+	`ftbench' as follows on a Galaxy Nexus:

+	for the degenerate case.
+
+2013-06-09  David Turner  <digit@google.com>
+
+	* src/cache/ftcmanag.c (FTC_Manager_Reset): Add missing cache flush.
+
+	This code, present since eight(!) years in the unused `CACHE'
+	branch, has been forgotten to apply to the master branch.  It's
+	really amazing that noone has ever complained since
+	`FTC_Manager_Reset' is pretty useless without flushing the cache.

+	  cntrmask/hintmask
+	  hmoveto
+	  vmoveto

+	Problem reported by Ingmar Sittl <ingmar.sittl@elektrobit.com>.
+
+2013-06-04  Werner Lemberg  <wl@gnu.org>
+
+	Apply fixes for cppcheck nitpicks.
+
+	  http://cppcheck.sourceforge.net/
+
+	The call was (from the top-level of the FreeType tree):
+
+	  cppcheck --force \
+	           --enable=all \
+	           -I include \
+	           -I include/freetype/ \
+	           -I include/freetype/config/ \
+	           -I include/freetype/internal/ \
+	           . &> cppcheck.log
+
+	Note that the current version heavily chokes on FreeType, delivering
+	many wrong results.  I will report those issues to the cppcheck team
+	so that a newer version gives improved results hopefully.
+
+	*/* Improve variable scopes.
+	*/* Remove redundant initializations which get overwritten.
+
+	* src/base/ftmac.c, builds/mac/ftmac.c (count_faces_scalable):
+	Remove unused variable.
+
+	* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.

+	* devel/ftoption.h, include/freetype/config/ftoption.h
+	(CFF_CONFIG_OPTION_OLD_ENGINE): New macro.
+
+	* src/cff/cffdrivr.c (cff_property_set), src/cff/cffgload.c
+	(CFF_Operator, cff_argument_counts, cff_builder_add_point,

+	LIBPNG_LDFLAGS.
+
+2013-05-23  Behdad Esfahbod  <behdad@google.com>
+
+	Add support for color embedded bitmaps (eg. color emoji).
+
+	A new load flag, FT_LOAD_COLOR, makes FreeType load color
+	embedded-bitmaps, following this draft specification
+
+	  https://color-emoji.googlecode.com/git/specification/v1.html
+
+	which defines two new SFNT tables, `CBDT' and `CBLC' (named and
+	modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
+	are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
+	pre-multiplied sRGB images.  If PNG support is available, PNG color
+	images as defined in the same proposed specification are supported
+	also.
+
+	Note that color bitmaps are converted to grayscale if client didn't
+	ask for color.
+
+	* builds/unix/configure.raw: Search for libpng.

+
+	* src/tools/apinames.c (PROGRAM_VERSION): Set to 0.2.
+	(OutputFormat): Add `OUTPUT_NETWARE_IMP'.
+	(names_dump): Handle it.
+	(usage): Updated.
+	(main): Handle new command line flag `-wN'.

+
+	* Jamfile: Update the directories of the header files scanned for

+
+	[smooth] Sub-banding protocol revision.
+
+	Rasterization sub-banding is utilized at large sizes while using a
+	rather small fixed memory pool.  Indeed it is possible to make an
+	educated guess how much memory is necessary at a given size for a
+	given glyph.  It turns out that, for a large majority of European
+	glyphs, you should store about 8 times more boundary pixels than
+	their height.  Or, vice versa, if your memory pool can hold 800
+	pixels the band height should be 100 and you should sub-band
+	anything larger than that.  Should you still run out of memory,
+	FreeType bisects the band but you have wasted some time.  This is
+	what has been implemented in FreeType since the beginning.
+
+	It was overlooked, however, that the top band could grow to twice
+	the default band size leading to unnecessary memory overflows there.
+	This commit fixes that.  Now the bands are distributed more evenly
+	and cannot exceed the default size.
+
+	Now the magic number 8 is really suitable for rather simple European
+	scripts.  For complex Chinese logograms the magic number should be
+	13 but that is subject for another day.
+
+	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
+	protocol.

+
+	[truetype] Let SHPIX move points in the twilight zone in v40.
+
+	* src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in

+
+2016-05-28  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
+
+	Suggested by Alexei.  `UL' is only needed for 16bit compilers, but
+	it seems noone is using this anymore (and we no longer test whether
+	FreeType compiles in such an environment).  Otherwise, it is easy to
+	add the postfix to the `AF_UNICODE_RANGE' macro.
+
+2016-05-26  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Shrink bisection stack.
+
+	The convergence of Bézier flatteners is fast with the deviation
+	from straight line being assymptotically cut 4-fold on each bisection.
+	This justifies smaller bisection stack size.
+
+	* src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
+	(gray_render_conic): Create and use conic `bez_stack'. Move back the

+
+2016-05-23  Werner Lemberg  <wl@gnu.org>
+
+	* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
+
+	This was commented about 10 years ago – I think the reason then to
+	disable libtool's `-export-symbols' option was to give some badly
+	programmed applications access to internal FreeType functions.
+
+	I believe that we should no longer take care of such programs; the
+	number of symbols exported should be rather restricted as much as
+	possible.
+
+2016-05-22  Werner Lemberg  <wl@gnu.org>
+

+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+	* src/autofit/afscript.h: Add Gurmukhi standard characters and move

+
+	* src/autofit/afranges.c: Move Gurmukhi data out of

+
+2016-05-21  Werner Lemberg  <wl@gnu.org>

+
+	[autofit] Add support for Georgian scripts.
+
+	Georgian is problematic, since `uppercase' forms of Mkhedruli
+	(called Mtavruli) are not yet defined in Unicode, which means that
+	proper blue zones can't be defined.  However, there is already a
+	proposal submitted to Unicode; see
+
+	  http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
+
+	Additionally, due to historical reasons, Unicode treats Khutsuri as
+	the same script as Mkhedruli, and so does OpenType.  However, since
+	the two scripts have completely different shapes it can happen that
+	blue zones differ considerably.  The tag `geok' used here (derived
+	from ISO 15924) to differentiate the two scripts is not an OpenType
+	tag in use.  If we now have a font that contains both glyphs for
+	Mkhedruli and Khutsuri, and it uses OpenType features for both also,
+	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,
+	blue zones for `geok' are not used for glyphs involved in the
+	OpenType features.
+
+	An issue not yet resolved is which OpenType feature should be used
+	to access Mtavruli glyph shapes; right now, FreeType doesn't set up
+	support for them, but it is easy to add them later on as soon as
+	more information is available.

+
+	[autofit] Fix handling of default script.
+
+	Patch taken from ttfautohint, commit
+	071ae2c00e0d67f9d19418f4fade1c23d27dc185.
+
+	There were two bugs.
+
+	  - We now use non-standard script tags like `khms' for special
+	    purposes.  However, HarfBuzz maps such tags to `DFLT', and
+	    without this commit the associated lookups were incorrectly
+	    assigned to the non-standard tags.
+
+	  - Let's assume we have a Bengali font, and the font's `DFLT'
+	    script tag handles the necessary lookups for Bengali, too.
+	    Without this commit, the `DFLT' lookups were assigned to
+	    ttfautohint's default script (usually `latn') before the
+	    standard lookups for Bengali were handled.
+
+	    We now have the following order while searching for covered
+	    glyph indices.
+
+	      special features of scripts (e.g. `sups' for Cyrillic)
+	      Unicode mappings of scripts
+	      remaining features of scripts (especially important for Indic
+	        scripts)
+	      default features of default script
+
+	* src/autofit/afshaper.c, src/autofit/afshaper.h
+	(af_shaper_get_coverage): Add boolean parameter to indicate default
+	script.
+	Update all callers.
+
+	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
+	Fix search order for coverages.
+

+
+	This was removed while rewriting the HarfBuzz interface.
+
+	* src/autofit/afglobal.h (AF_FaceGlobalsRec): Add `hb_buf' field to

+2015-12-09  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Thinko.
+
+	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count
+	empty blue zones (bug introduced 2015-12-06).
+
+2015-12-09  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Introduce subscript top blue zones.
+
+	This feature is mainly for Khmer: The idea is to avoid a clash
+	between the top of subscript glyphs and the bottom of normal
+	baseline glyphs.
+
+	This only works for character clusters mapped to multiple glyphs.
+
+	* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.
+
+	* src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
+	macro.
+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

+
+2015-12-06  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/afblue.dat: Add more Khmer clusters.
+
+	Some fonts have incorrect ligatures; we need more samples to get a
+	good mean value.
+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+2015-12-06  Werner Lemberg  <wl@gnu.org>

+	[autofit] Typos.
+
+	* src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_get_elem)
+	[!FT_CONFIG_OPTION_USE_HARFBUZZ]: Make it compile.
+
+2015-12-06  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Add support for Khmer script.
+
+	We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
+	`Khmer symbols' (`khms', U+19E0-U+19FF).
+
+	* src/autofit/afblue.dat: Add blue zone data for Khmer.
+
+	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
+
+	* src/autofit/afscript.h: Add Khmer standard characters.
+

+
+	* src/autofit/afstyles.h: Add Khmer data.
+
+2015-12-06  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Rewrite HarfBuzz interface to support character clusters.
+
+	Scripts like Khmer have blue zones that can't be directly
+	represented by Unicode characters.  Instead, it is necessary to let
+	HarfBuzz convert character clusters into proper glyph representation
+	forms, then deriving the blue zone information from the resulting
+	glyphs.
+
+	* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
+	* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
+	files, providing a new API to access HarfBuzz.
+
+	The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
+	and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
+	string with function `af_shaper_get_cluster', and the resulting
+	glyph data (indices, advance widths, vertical offsets) can be
+	iteratively accessed with function `af_shaper_get_elem'.
+
+	* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
+	af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.
+
+	* src/autofit/aflatin.c (af_latin_metrics_init_widths,
+	af_latin_metrics_init_blues, af_latin_metrics_check_digits):

+	* src/autofit/afglobal.h: s/hbshim.h/afshaper.h/.
+
+	* src/autofit/autofit.c: s/hbshim.c/afshaper.c/.
+
+	* src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC):
+	Updated.
+
+2015-12-06  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Prepare forthcoming changes.
+
+	This makes it easier to control the commits.
+
+	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Add dummy
+	loop.  No functional change.
+
+2015-12-06  Werner Lemberg  <wl@gnu.org>
+
+	[autofit] Use string of standard characters.
+
+	This is more flexible; additionally, it would allow character
+	clusters.
+
+	* src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
+	(AF_ScriptClassRec): Replace `standard_char[123]' with
+	`standard_charstring'.
+
+	* src/autofit/afscript.h: Replace last three character arguments
+	of the `SCRIPT' calls with a string parameter, holding the standard
+	characters (in UTF-8 encoding) separated with spaces.
+
+	* src/autofit/afglobal.c, src/autofit/afglobal.h,
+	src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c
+	(SCRIPT): Updated.
+
+	* src/autofit/afcjk.c (af_cjk_metrics_init_widths),
+	src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.
+
+2015-12-05  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/afblue.dat: Separate blue zone characters with spaces.

+
+2015-12-05  Werner Lemberg  <wl@gnu.org>
+
+	* src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces.
+
+	Instead, reduce multiple spaces to a single one.  We need this later
+	for supporting character clusters in `afblue.dat'.
+
+2015-12-05  Werner Lemberg  <wl@gnu.org>
+
+	* src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'.

+
+2015-11-02  Ben Wagner  <bungeman@gmail.com>
+
+	[ftfuzzer] Add support for multiple files (patch #8779).
+
+	Currently, libFuzzer only supports mutation of a single file.  We
+	circumvent this problem by using an uncompressed tar archive as
+	multiple-file input for the fuzzer.
+
+	This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
+	a constructed tarball should contain a font file as the first
+	element, and files to be attached as further elements.
+
+	* src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
+	(archive_read_entry_data, parse_data): New functions.
+	(LLVMFuzzerTestOneInput): Updated.
+
+	* src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom

+
+	[smooth] Faster alternative line renderer.
+
+	This implementation renders the entire line segment at once without
+	subdividing it into scanlines.  The main speed improvement comes from
+	reducing the number of divisions to just two per line segment, which
+	is a bare minimum to calculate cell coverage in a smooth rasterizer.
+	Notably, the progression from cell to cell does not itself require any
+	divisions at all.  The speed improvement is more noticeable at larger
+	sizes.

+	[sfnt] Improve handling of invalid SFNT table entries (#45987).
+
+	This patch fixes weaknesses in function `tt_face_load_font_dir'.
+
+	- It incorrectly assumed that valid tables are always at the
+	  beginning.  As a consequence, some valid tables after invalid
+	  entries (which are ignored) were never seen.
+
+	- Duplicate table entries (this is, having the same tag) were not

+
+	- The number of valid tables was sometimes too large, leading to
+	  access of invalid tables.

+	of valid tables.
+	Add another tracing message.

+
+	[autofit] Redesign code ranges (1/2).
+
+	This patch introduces auxiliary code ranges that identify no-base
+	characters; they refer to glyphs of a script that should be hinted
+	without alignments to blue zones (mostly diacritics).
+
+	It also splits off ranges for fallback scripts that handle subscript
+	and superscript characters not covered by OpenType features.  For
+	example, this greatly helps improve the hinting of various phonetic
+	alphabets, which contain a large amount characters that look like
+	superscript glyphs.
+
+	Finally, code ranges are updated to Unicode 8.0, and enclosed
+	characters are removed in general since they normally look better if
+	they stay unhinted.
+
+	* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
+	8.0.
+	Split off superscript-like and subscript-like glyphs into...

+
+	[truetype] In GX, make private point numbers work correctly.
+
+	This is completely missing in Apple's documentation: If a `gvar'
+	tuple uses private point numbers (this is, deltas are specified for

+	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.
+
+	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
+	tt_handle_deltas): New functions.
+	(TT_Vary_Get_Glyph_Deltas): Renamed to...
+	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the

+	Add tracing information.
+	Call `tt_handle_deltas' to interpolate missing deltas.
+	Also fix a minor memory leak in case of error.

+2015-05-22  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Support selector index 3 of the INSTCTRL instruction.
+
+	This flag activates `native ClearType hinting', disabling backwards

+
+	[truetype] Fix loading of composite glyphs.
+
+	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
+	ARGS_ARE_XY_VALUES flag is not set, handle argument values as
+	unsigned.  I trust `ttx' (which has exactly such code) that it does
+	the right thing here...
+
+	The reason that noone has ever noticed this bug is probably the fact
+	that point-aligned subglyphs are rare, as are subglyphs with a
+	number of points in the range [128;255], which is quite large (or
+	even in the range [32768;65535], which is extremely unlikely).

+	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
+	pulling values off the stack until the stack is exhausted.
+	Implicitly the stack must be a multiple (or for subtly different
+	behaviour) a multiple plus a specific number of extra values deep.
+	If that's not the case, enforce it (as the old code did).

+	incremental interface callback to apply the encoding to raw
+	character index (as it was in the previous code).

+
+	[raster] Fix Savannah bug #44022.
+
+	Add fallback for glyphs with degenerate bounding boxes.
+
+	If a glyph has only one very narrow feature, the bbox can end up
+	with either the width or height of the bbox being 0, in which case
+	no raster memory is allocated and no attempt is made to render the
+	glyph.  This is less than ideal when the drop-out compensation in
+	the rendering code would actually result in the glyph being
+	rendered.
+
+	This problem can be observed with the `I' glyph (gid 47) in the
+	Autodesk RomanS TrueType font.
+
+	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either

+
+	[autofit] Reuse slot glyph loader.
+
+	No need to create a new glyph loader; we can reuse the one from
+	`slot->internal->loader'.  It's hard to tell why it was written that
+	way originally, but new code looks sound and correct to me, and
+	avoids lots of allocations.
+

+	Don't call `FT_GlyphLoader_New'.
+	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.

+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Remove (unused) support for composite glyphs.
+
+	We never have to deal with composite glyphs in the autohinter, as
+	those will be loaded into FORMAT_OUTLINE by the recursed
+	`FT_Load_Glyph' function.
+
+	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
+	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
+	FT_LOAD_NO_HINTING:
+
+	  /* resolve load flags dependencies */
+
+	  if ( load_flags & FT_LOAD_NO_RECURSE )
+	    load_flags |= FT_LOAD_NO_SCALE         |
+	                  FT_LOAD_IGNORE_TRANSFORM;
+
+	  if ( load_flags & FT_LOAD_NO_SCALE )
+	  {
+	    load_flags |= FT_LOAD_NO_HINTING |
+	                  FT_LOAD_NO_BITMAP;
+
+	    load_flags &= ~FT_LOAD_RENDER;
+	  }
+
+	and as such the auto-hinter is never called.  Thus, the recursion in
+	`af_loader_load_g' never actually happens.  So remove the depth
+	counter as well.
+
+	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
+	parameter.
+	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
+	(af_loader_load_glyph): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Fix uninitialized memory access.
+
+	Apparently `ras.cProfile' might be uninitialized.  This will be the
+	case if `ras.top == ras.cProfile->offset', as can be seen in
+	`End_Profile'.  The overshoot code introduced in a change `Fix B/W
+	rasterization of subglyphs with different drop-out modes.' (from
+	2009-06-18) violated this, accessing `ras.cProfile->flags'
+	unconditionally just before calling `End_Profile' (which then
+	detected that `cProfile' is uninitialized and didn't touch it).
+
+	This was harmless, and was not detected by valgrind before because
+	the objects were allocated on the `raster_pool', which was always
+	initialized.  With recent change to allocate raster buffers on the
+	stack, valgrind now reported this invalid access.
+
+	* src/raster/ftraster.c (Convert_Glyph): Don't access an
+	uninitialized `cProfile'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[smooth] Fix uninitialized memory access.
+
+	Looks like `ras.span_y' could always be used without initialization.
+	This was never detected by valgrind before because the library-wide
+	`raster_pool' was used for the worker object and `raster_pool' was
+	originally zero'ed.  But subsequent reuses of it were using `span_y'
+	uninitialized.  With the recent change to not use `render_pool' and
+	allocate worker and buffer on the stack, valgrind now detects this
+	uninitialized access.

+
+	[base] Don't allocate `library->raster_pool' anymore.
+
+	It's unused after the following commits:
+
+	  [raster] Allocate render pool for mono rasterizer on the stack.
+	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
+	serve, which is, to adjust the pool size.  But the pool is now
+	allocated on the stack on demand.
+
+	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[base] Do not reorder library->renderers upon use.
+
+	Instead of keeping `library->renderers' in a MRU order, just leave
+	it as-is.  The MRU machinery wasn't thread-safe.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't fail choosing rasterizer
+	(FT_Err_Cannot_Render_Glyph).
+
+	Easiest to see that crash was to add a `printf' (or otherwise let
+	thread yield in FT_Throw with debugging enabled).
+
+	* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
+	(FT_Outline_Render): Don't call `FT_Set_Renderer'.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Allocate render pool for mono rasterizer on the stack.
+
+	Instead of using the `render_pool' member of `FT_Library' that is
+	provided down to the rasterizer, completely ignore that and allocate
+	needed objects on the stack instead.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't crash in the monochrome rasterizer.
+
+	* src/raster/ftraster.c (black_TRaster): Remove `buffer',
+	`buffer_size', and `worker' members.
+
+	(ft_black_render): Create `buffer' locally.
+	(ft_black_reset): Updated.
+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[raster] Remove 5-level gray AA mode from monochrome rasterizer.
+
+	It was off by default and couldn't be turned on at runtime.  And the
+	smooth rasterizer superceded it over ten years ago.  No point in
+	keeping.  Comments suggested that it was there for compatibility
+	with FreeType 1.
+
+	550 lines down.
+
+	* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
+	RASTER_GRAY_LINES): Remove macros and all associated code.
+
+	(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
+	(black_TRaster): Remove `grays' and `gray_width'.
+
+	(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,

+
+	* src/raster/ftrend1.c (ft_raster1_render): Simplify code.

+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[smooth] Allocate render pool for smooth rasterizer on the stack.
+
+	Instead of using the `render_pool' member of `FT_Library' that is
+	provided down to the rasterizer, completely ignore that and allocate
+	needed objects on the stack instead.
+
+	With this patch, rasterizing glyphs from different faces from
+	different threads doesn't crash in the smooth rasterizer.

+

+	`buffer_size', `band_size', and `worker' members.
+
+	(gray_raster_render): Create `buffer', `buffer_size', and

+
+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.
+
+	Previously the code had stipulation for using a per-TT_Size exec
+	context if `size->debug' was true.  But there was no way that
+	`size->debug' could *ever* be true.  As such, the code was always
+	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
+	This was, clearly, not threadsafe.
+
+	With this patch, loading glyphs from different faces from different
+	threads doesn't crash in the bytecode loader code.
+
+	* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
+	(TT_DriverRec): Remove `context' member.
+
+	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
+	`TT_ExecContext' code related to a global `TT_Driver' object.
+
+	(tt_driver_done): Don't remove `TT_ExecContext' object here but ...
+	(tt_size_done_bytecode): ... here.
+
+	(tt_driver_init): Don't create `TT_ExecContext' object here but ...
+	(tt_size_init_bytecode): ... here, only on demand.
+
+	* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
+	code.
+	(TT_New_Context): Remove `TT_ExecContext' code related to a global
+	`TT_Driver' object.

+2015-01-14  Behdad Esfahbod  <behdad@behdad.org>
+
+	[autofit] Allocate AF_Loader on the stack instead of AF_Module.
+
+	Stop sharing a global `AF_Loader'.  Allocate one on the stack during
+	glyph load.
+
+	Right now this results in about 25% slowdown, to be fixed in a
+	following commit.
+
+	With this patch loading glyphs from different faces from different
+	threads doesn't immediately crash in the autohinting loader code.
+
+	Bugs:
+
+	  https://bugzilla.redhat.com/show_bug.cgi?id=1164941
+
+	* src/autofit/afloader.c (af_loader_init): Pass
+	`AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments.
+	(af_loader_reset, af_loader_load_glyph): Also pass `loader' as
+	argument.
+	(af_loader_done): Use `AF_Loader' instead of `AF_Module' as
+	argument.
+
+	* src/autofit/afmodule.c (af_autofitter_init): Don't call
+	`af_loader_init'.
+	(af_autofitter_done): Don't call `af_loader_done'.
+	(af_autofitter_load_glyph): Use a local `AF_Loader' object.

+This means  that *you* must choose  *one* of the  two licenses described
+below, then obey  all its terms and conditions when  using FreeType 2 in
+any of your projects or products.
+
+  - The FreeType License, found in  the file `FTL.TXT', which is similar
+    to the original BSD license *with* an advertising clause that forces
+    you  to  explicitly cite  the  FreeType  project  in your  product's
+    documentation.  All  details are in the license  file.  This license
+    is  suited  to products  which  don't  use  the GNU  General  Public
+    License.
+
+    Note that  this license  is  compatible  to the  GNU General  Public
+    License version 3, but not version 2.
+
+  - The GNU General Public License version 2, found in  `GPLv2.TXT' (any
+    later version can be used  also), for programs which already use the
+    GPL.  Note  that the  FTL is  incompatible  with  GPLv2 due  to  its
+    advertisement clause.
+
+The contributed BDF and PCF drivers  come with a license similar to that
+of the X Window System.  It is compatible to the above two licenses (see
+file src/bdf/README and  src/pcf/README).  The same holds  for the files
+`fthash.c' and  `fthash.h'; their  code was  part of  the BDF  driver in
+earlier FreeType versions.
+
+The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
+compatible to the above two licenses.
+
+The MD5 checksum support (only used for debugging in development builds)
+is in the public domain.

+  FreeType 2.7.1
+  ==============
+
+  Homepage: http://www.freetype.org
+
+  FreeType is a freely available software library to render fonts.
+
+  It  is  written  in  C,  designed to  be  small,  efficient,  highly
+  customizable, and  portable while capable of  producing high-quality
+  output  (glyph  images) of  most  vector  and bitmap  font  formats.
+
+  Please   read   the  docs/CHANGES   file,   it  contains   IMPORTANT
+  INFORMATION.
+
+  Read the  files `docs/INSTALL*'  for installation  instructions; see
+  the file `docs/LICENSE.TXT' for the available licenses.
+
+  The FreeType 2 API reference is located in `docs/reference'; use the
+  file   `ft2-toc.html'   as   the   top  entry   point.    Additional
+  documentation is available as a separate package from our sites.  Go
+  to
+
+    http://download.savannah.gnu.org/releases/freetype/
+
+  and download one of the following files.
+
+    freetype-doc-2.7.1.tar.bz2

+  To view the documentation online, go to
+
+    http://www.freetype.org/freetype2/documentation.html
+
+
+  Mailing Lists
+  =============
+
+  The preferred way  of communication with the FreeType  team is using
+  e-mail lists.
+
+    general use and discussion:      freetype@nongnu.org
+    engine internals, porting, etc.: freetype-devel@nongnu.org
+    announcements:                   freetype-announce@nongnu.org
+    git repository tracker:          freetype-commit@nongnu.org
+
+  The lists are moderated; see
+
+    http://www.freetype.org/contact.html
+
+  how to subscribe.
+
+
+  Bugs
+  ====
+
+  Please submit bug reports at
+
+    https://savannah.nongnu.org/bugs/?group=freetype
+
+  Alternatively,    you   might    report    bugs    by   e-mail    to
+  `freetype-devel@nongnu.org'.   Don't  forget   to  send  a  detailed
+  explanation of the problem --  there is nothing worse than receiving
+  a terse message that only says `it doesn't work'.
+
+
+  Enjoy!

+The git  archive doesn't  contain pre-built configuration  scripts for
+UNIXish platforms.  To generate them say
+
+  sh autogen.sh
+
+which in turn depends on the following packages:
+
+  automake (1.10.1)
+  libtool (2.2.4)
+  autoconf (2.62)
+
+The versions given  in parentheses are known to  work.  Newer versions
+should work too, of course.   Note that autogen.sh also sets up proper
+file permissions for the `configure' and auxiliary scripts.
+
+The autogen.sh script  now checks the version of  above three packages
+whether they match the numbers  above.  Otherwise it will complain and
+suggest either upgrading or using  an environment variable to point to
+a more recent version of the required tool(s).
+
+Note that  `aclocal' is provided  by the `automake' package  on Linux,
+and that `libtoolize' is called `glibtoolize' on Darwin (OS X).
+
+
+For static builds which  don't use platform specific optimizations, no
+configure script is necessary at all; saying
+
+  make setup ansi
+  make
+
+should work on all platforms which have GNU make (or makepp).
+
+
+Similarly, a  build with  `cmake' can  be done  directly from  the git
+repository.

+The makefile.os4 is for the AmigaOS4 SDK.  To use it, type
+"make -f makefile.os4", it produces a link library libft2_ppc.a.
+
+The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on
+68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de).
+To use it, type "make assign", then "make"; it produces a link library
+libft2_ppc.a.
+
+The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available,
+latest sold version was 6.50, updates can be found in Aminet).  It is
+based on the version found in the sourcecode of ttf.library 0.83b for
+FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com,
+http://ragriffi.home.sprynet.com).
+
+You will also need the latest include files and amiga.lib from the
+Amiga web site (http://www.amiga.com/3.9/download/NDK3.9.lha) for
+AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up.
+
+To use it, call "smake assign" and then "smake" from the builds/amiga
+directory.  The results are:
+
+- A link library "ft2_680x0.lib" (where x depends on the setting of
+  the CPU entry in the smakefile) containing all FreeType2 parts
+  except of the init code, debugging code, and the system interface
+  code.
+
+- ftsystem.o, an object module containing the standard version of the
+  system interface code which uses fopen() fclose() fread() fseek()
+  ftell() malloc() realloc() and free() from lib:sc.lib (not pure).
+
+- ftsystempure.o, an object module containing the pure version of the
+  system interface code which uses Open() Close() Read() Seek()
+  ExamineFH() AsmAllocPooled() AsmFreePooled() etc.  This version can
+  be used in both normal programs and in Amiga run-time shared system
+  librarys (can be linked with lib:libinit.o, no copying of DATA and
+  BSS hunks for each OpenLibrary() necessary).  Source code is in
+  src/base/ftsystem.c.
+
+- ftdebug.o, an object module containing the standard version of the
+  debugging code which uses vprintf() and exit() (not pure).
+  Debugging can be turned on in FT:include/freetype/config/ftoption.h
+  and with FT_SetTraceLevel().
+
+- ftdebugpure.o, an object module containing the pure version of the
+  debugging code which uses KVPrintf() from lib:debug.lib and no
+  exit().  For debugging of Amiga run-time shared system libraries.
+  Source code is in src/base/ftdebug.c.
+
+- NO ftinit.o.  Because linking with a link library should result in
+  linking only the needed object modules in it, but standard
+  ftsystem.o would force ALL FreeType2 modules to be linked to your
+  program, I decided to use a different scheme: You must #include
+  FT:src/base/ftinit.c in your sourcecode and specify with #define
+  statements which modules you need.  See
+  include/freetype/config/ftmodule.h.
+
+
+To use in your own programs:
+
+- Insert the #define and #include statements from top of
+  include/freetype/config/ftmodule.h in your source code and
+  uncomment the #define statements for the FreeType2 modules you need.
+
+- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for
+  calling the FreeType2 functions, because the link library and the
+  object files are compiled with PARAMETERS=BOTH.
+
+- "smake assign" (assign "FT:" to the FreeType2 main directory).
+
+- Compile your program.
+
+- Link with either ftsystem.o or ftsystempure.o, if debugging enabled
+  with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with
+  ft2_680x0.lib as link library.
+
+
+To adapt to other compilers:
+
+- The standard ANSI C maximum length of 31 significant characters in
+  identifiers is not enough for FreeType2.  Check if your compiler has
+  a minimum length of 40 significant characters or can be switched to
+  it.  "idlen=40" is the option for SAS/C.  Setting #define
+  HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested).
+
+- Make sure that the include directory in builds/amiga is searched
+  before the normal FreeType2 include directory, so you are able to
+  replace problematic include files with your own version (same may be
+  useful for the src directory).
+
+- An example of how to replace/workaround a problematic include file
+  is include/freetype/config/ftconfig.h; it changes a #define that
+  would prevent SAS/C from generating XDEF's where it should do that and
+  then includes the standard FreeType2 include file.

+Compiling FreeType 2 with PureC compiler
+========================================
+
+[See below for a German version.]
+
+To compile FreeType 2 as a library the following changes must be applied:
+
+- All *.c files must start with an uppercase letter.
+  (In case GEMSCRIPT is available:
+  Simply drag the whole FreeType 2 directory to the file `FNames.SIC'.)
+
+- You have to change the INCLUDE directory in PureC's compiler options
+  to contain both the `INCLUDE' and `freetype2\include' directory.
+  Example:
+
+    INCLUDE;E:\freetype2\include
+
+- The file `freetype2/include/Ft2build.h' must be patched as follows to
+  include ATARI.H:
+
+    #ifndef FT2_BUILD_GENERIC_H_
+    #define FT2_BUILD_GENERIC_H_
+
+    #include "ATARI.H"
+
+
+
+Compilieren von FreeType 2 mit PureC
+====================================
+
+Um FreeType 2 als eine Bibliothek (library) zu compilieren, muss folgendes
+ge„ndert werden:
+
+- Alle *.c-files m�ssen mit einem GROSSBUCHSTABEN beginnen.
+  (Falls GEMSCRIPT zur Verf�gung steht:
+  Den kompletten Ordner freetype2 auf die Datei `FNames.SIC' draggen.)
+
+- In den Compiler-Optionen von PureC muss das INCLUDE directory auf INCLUDE
+  und freetype2\include verweisen. Z.B.:
+
+    INCLUDE;E:\freetype2\include
+
+- In der Datei freetype2/include/Ft2build.h muss zu Beginn
+  ein #include "ATARI.H" wie folgt eingef�gt werden:
+
+    #ifndef FT2_BUILD_GENERIC_H_
+    #define FT2_BUILD_GENERIC_H_
+
+    #include "ATARI.H"

+#
+#
+# This file is derived from the files `Platform/Darwin.cmake' and
+# `Platform/UnixPaths.cmake', which are part of CMake 2.8.4.  It has been
+# altered for iOS development.
+
+
+# Options
+# -------
+#
+#   IOS_PLATFORM = OS | SIMULATOR
+#
+#     This decides whether SDKS are selected from the `iPhoneOS.platform' or
+#     `iPhoneSimulator.platform' folders.
+#
+#     OS - the default, used to build for iPhone and iPad physical devices,
+#       which have an ARM architecture.
+#     SIMULATOR - used to build for the Simulator platforms, which have an
+#       x86 architecture.
+#
+#   CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder
+#
+#     By default, this location is automatically chosen based on the
+#     IOS_PLATFORM value above.  If you manually set this variable, it
+#     overrides the default location and forces the use of a particular
+#     Developer Platform.
+#
+#   CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder
+#
+#     By default, this location is automatically chosen based on the
+#     CMAKE_IOS_DEVELOPER_ROOT value.  In this case it is always the most
+#     up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.  If you
+#     manually set this variable, it forces the use of a specific SDK
+#     version.
+#
+#
+# Macros
+# ------
+#
+#   set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE)
+#
+#     A convenience macro for setting Xcode specific properties on targets.
+#
+#     Example:
+#
+#       set_xcode_property(myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1")
+#
+#   find_host_package (PROGRAM ARGS)
+#
+#     A macro to find executable programs on the host system, not within the
+#     iOS environment.  Thanks to the `android-cmake' project for providing

+This folder contains
+
+  * Makefile skeletons for Apple MPW (Macintosh's Programmer's Workshop)
+
+  * Python script to generate MPW makefile from skeleton
+
+  * Metrowerks CodeWarrior 9.0 project file in XML format
+
+------------------------------------------------------------
+
+1. What is this
+---------------
+
+Files in this directory are designed to build FreeType
+running on classic MacOS. To build FreeType running on
+Mac OS X, build as the system is UNIX.
+
+However, Mac OS X is most useful to manipulate files in
+vanilla FreeType to fit classic MacOS.
+
+The information about MacOS specific API is written in
+appendix of this document.
+
+2. Requirement
+--------------
+
+You can use MPW: a free-charged developer environment
+by Apple, or CodeWarrior: a commercial developer
+environment by Metrowerks. GCC for MPW and Symantec
+"Think C" are not tested at present.
+
+
+  2-1. Apple MPW
+  --------------
+
+  Following C compilers are tested:
+
+      m68k target:	Apple SC  8.9.0d3e1
+      ppc  target:	Apple MrC 5.0.0d3c1
+
+  The final MPW-GM (official release on 1999/Dec) is too
+  old and cannot compile FreeType, because bundled C
+  compilers cannot search header files in sub directories.
+  Updating by the final MPW-PR (pre-release on 2001/Feb)
+  is required.
+
+  Required files are downloadable from:
+
+      http://developer.apple.com/tools/mpw-tools/index.html
+
+  Also you can find documents how to update by MPW-PR.
+
+  Python is required to restore MPW makefiles from the
+  skeletons. Python bundled to Mac OS X is enough. For
+  classic MacOS, MacPython is available:
+
+      http://homepages.cwi.nl/~jack/macpython/
+
+  MPW requires all files are typed by resource fork.
+  ResEdit bundled to MPW is enough. In Mac OS X,
+  /Developer/Tools/SetFile of DevTool is useful to
+  manipulate from commandline.
+
+  2-2. Metrowerks CodeWarrior
+  ---------------------------
+
+  XML project file is generated and tested by
+  CodeWarrior 9.0.  Older versions are not tested
+  at all. At present, static library for ppc target
+  is available in the project file.
+
+
+3. How to build
+---------------
+
+  3-1. Apple MPW
+  --------------
+  Detailed building procedure by Apple MPW is
+  described in following.
+
+    3-1-1. Generate MPW makefiles from the skeletons
+    ------------------------------------------------
+
+    Here are 4 skeletons for following targets are
+    included.
+
+    - FreeType.m68k_far.make.txt
+      Ancient 32bit binary executable format for
+      m68k MacOS: System 6, with 32bit addressing
+      mode (far-pointer-model) So-called "Toolbox"
+      API is used.
+
+    - FreeType.m68k_cfm.make.txt
+      CFM binary executable format for m68k MacOS:
+      System 7. So-called "Toolbox" API is used.
+
+    - FreeType.ppc_classic.make.txt
+      CFM binary executable format for ppc MacOS:
+      System 7, MacOS 8, MacOS 9. So-called "Toolbox"
+      API is used.
+
+    - FreeType.ppc_carbon.make.txt
+      CFM binary executable format for ppc MacOS:
+      MacOS 9. Carbon API is used.
+
+    At present, static library is only supported,
+    although targets except of m68k_far are capable
+    to use shared library.
+
+    MPW makefile syntax uses 8bit characters. To keep
+    from violating them during version control, here
+    we store skeletons in pure ASCII format. You must
+    generate MPW makefile by Python script ascii2mpw.py.
+
+    In Mac OS X terminal, you can convert as:
+
+	python builds/mac/ascii2mpw.py \
+		< builds/mac/FreeType.m68k_far.make.txt \
+		> FreeType.m68k_far.make
+
+    The skeletons are designed to use in the top
+    directory where there are builds, include, src etc.
+    You must name the generated MPW makefile by removing
+    ".txt" from source skeleton name.
+
+    3-1-2. Add resource forks to related files
+    ------------------------------------------
+
+    MPW's Make and C compilers cannot recognize files
+    without resource fork. You have to add resource
+    fork to the files that MPW uses. In Mac OS X
+    terminal of the system, you can do as:
+
+	find . -name '*.[ch]' -exec \
+		/Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
+
+	find . -name '*.make' -exec \
+		/Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \;
+
+
+    3-1-3. Open MPW shell and build
+    -------------------------------
+
+    Open MPW shell and go to the top directory that
+    FreeType sources are extracted (MPW makefile must
+    be located in there), from "Set Directory" in
+    "Directory" menu.
+
+    Choose "Build" from "Build" menu, and type the
+    name of project by removing ".make" from MPW
+    makefile, as: FreeType.m68k_far
+
+    If building is successfully finished, you can find
+    built library in objs/ directory.
+
+
+  3-2. Metrowerks CodeWarrior
+  ---------------------------
+
+  Detailed building procedure by Metrowerks
+  CodeWarrior (CW) 9.0 is described in following.
+
+    3-2-1. Import XML project file
+    ------------------------------
+
+    CW XML project file is not ready for double-
+    click. Start CodeWarrior IDE, and choose
+    "Import project" in "File" menu. Choose XML
+    project file: builds/mac/ftlib.prj.xml.
+    In next, you will be asked where to save CW
+    native project file: you must choose
+    "builds/mac/ftlib.prj". The project file is
+    designed with relative path from there. After
+    CW native project file is generated, it is
+    automatically loaded, small project window
+    titled "ftlib.prj" is displayed.
+
+    3-2-2. Building
+    ---------------
+    Choose "Make" from "Project" menu. If building
+    is successfully finished, you can find built
+    library at objs/FreeTypeLib.
+
+4. TODO
+-------
+
+  4-1. All modules should be included
+  -----------------------------------
+
+  At present, MPW makefiles and CW project file are
+  just updated versions of these by Leonard. Some
+  modules are added after the last maintenance, they
+  are not included.
+
+  4-2. Working test with ftdemos
+  ------------------------------
+
+  At present, MPW makefiles and CW project file can
+  build FreeType for classic MacOS. But their working
+  behaviours are not tested at all. Building ftdemos
+  for classic MacOS and working test is required.
+
+  4-3. Porting Jam onto MPW
+  -------------------------
+
+  FreeType uses Jam (and FT-Jam) for unified cross-
+  platform building tool. At present, Jam is not ported
+  to MPW. To update classic MacOS support easily,
+  building by Jam is expected on MPW.
+
+
+APPENDIX I
+----------
+
+  A-1. Framework dependencies
+  ---------------------------
+
+  src/base/ftmac.c adds two Mac-specific features to
+  FreeType. These features are based on MacOS libraries.
+
+  * accessing resource-fork font
+  The fonts for classic MacOS store their graphical data
+  in resource forks which cannot be accessed via ANSI C
+  functions. FreeType2 provides functions to handle such
+  resource fork fonts, they are based on File Manager
+  framework of MacOS. In addition, HFS and HFS+ file
+  system driver of Linux is supported. Following
+  functions are for this purpose.
+
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+    FT_New_Face_From_FSRef()
+
+  * resolving font name to font file
+  The font menu of MacOS application prefers font name
+  written in FOND resource than sfnt resource. FreeType2
+  provides functions to find font file by name in MacOS
+  application, they are based on QuickDraw Font Manager
+  and Apple Type Service framework of MacOS.
+
+    FT_GetFile_From_Mac_Name()
+    FT_GetFile_From_Mac_ATS_Name()
+
+  Working functions for each MacOS are summarized as
+  following.
+
+  upto MacOS 6:
+    not tested (you have to obtain MPW 2.x)
+
+  MacOS 7.x, 8.x, 9.x (without CarbonLib):
+    FT_GetFile_From_Mac_Name()
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+
+  MacOS 9.x (with CarbonLib):
+    FT_GetFile_From_Mac_Name()
+    FT_New_Face_From_Resource()
+    FT_New_Face_From_FSSpec()
+    FT_New_Face_From_FSRef()
+
+  Mac OS X upto 10.4.x:
+    FT_GetFile_From_Mac_Name()     deprecated
+    FT_New_Face_From_FSSpec()      deprecated
+    FT_GetFile_From_Mac_ATS_Name() deprecated?
+    FT_New_Face_From_FSRef()
+
+  A-2. Deprecated Functions
+  -------------------------
+
+    A-2-1. FileManager
+    ------------------
+
+    For convenience to write MacOS application, ftmac.c
+    provides functions to specify a file by FSSpec and FSRef,
+    because the file identification pathname had ever been
+    unrecommended method in MacOS programming.
+
+    Toward to MacOS X 10.4 & 5, Carbon functions using FSSpec
+    datatype is noticed as deprecated, and recommended to
+    migrate to FSRef datatype. The big differences of FSRef
+    against FSSpec are explained in Apple TechNotes 2078.
+
+    http://developer.apple.com/technotes/tn2002/tn2078.html
+
+    - filename length: the max length of file
+    name of FSRef is 255 chars (it is limit of HFS+),
+    that of FSSpec is 31 chars (it is limit of HFS).
+
+    - filename encoding: FSSpec is localized by
+    legacy encoding for each language system,
+    FSRef is Unicode enabled.
+
+    A-2-2. FontManager
+    ------------------
+
+    Following functions receive QuickDraw fontname:
+
+      FT_GetFile_From_Mac_Name()
+
+    QuickDraw is deprecated and replaced by Quartz
+    since Mac OS X 10.4. They are still kept for
+    backward compatibility. By undefinition of
+    HAVE_QUICKDRAW in building, you can change these
+    functions to return FT_Err_Unimplemented always.
+
+    Replacement functions are added for migration.
+
+      FT_GetFile_From_Mac_ATS_Name()
+
+    They are usable on Mac OS X only. On older systems,
+    these functions return FT_Err_Unimplemented always.
+
+    The detailed incompatibilities and possibility
+    of FontManager emulation without QuickDraw is
+    explained in
+
+      http://www.gyve.org/~mpsuzuki/ats_benchmark.html
+
+  A-3. Framework Availabilities
+  -----------------------------
+
+  The framework of MacOS are often revised, especially
+  when new format of binary executable is introduced.
+  Following table is the minimum version of frameworks
+  to use functions used in FreeType2. The table is
+  extracted from MPW header files for assembly language.
+
+  *** NOTE ***
+  The conditional definition of available data type
+  in MPW compiler is insufficient. You can compile
+  program using FSRef data type for older systems
+  (MacOS 7, 8) that don't know FSRef data type.

+    (*)
+    In the "Classic": the original binary executable
+    format, these framework functions are directly
+    transformed to MacOS system call. Therefore, the
+    exact availability should be checked by running
+    system.
+
+    (**)
+    InterfaceLib is bundled to MacOS and its version
+    is usually equal to MacOS. There's no separate
+    update for InterfaceLib. It is supposed that
+    there's no InterfaceLib 9.x for m68k platforms.
+    In fact, these functions are FSRef dependent.
+
+    (***)
+    ATSUI framework is available on ATSUnicode 8.5 on
+    ppc Toolbox CFM, CarbonLib 1.0 too. But its base:
+    ATS font manager is not published in these versions.

+    Notes
+
+    Mac suitcase files can (and often do!) contain multiple fonts.  To
+    support this I use the face_index argument of FT_(Open|New)_Face()
+    functions, and pretend the suitcase file is a collection.
+
+    Warning: fbit and NFNT bitmap resources are not supported yet.  In old
+    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+    resources instead of the `bdat' table in the sfnt resource.  Therefore,
+    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+    resource is unavailable at present.
+
+    The Mac FOND support works roughly like this:
+
+    - Check whether the offered stream points to a Mac suitcase file.  This
+      is done by checking the file type: it has to be 'FFIL' or 'tfil'.  The
+      stream that gets passed to our init_face() routine is a stdio stream,
+      which isn't usable for us, since the FOND resources live in the
+      resource fork.  So we just grab the stream->pathname field.
+
+    - Read the FOND resource into memory, then check whether there is a
+      TrueType font and/or(!) a Type 1 font available.
+
+    - If there is a Type 1 font available (as a separate `LWFN' file), read
+      its data into memory, massage it slightly so it becomes PFB data, wrap
+      it into a memory stream, load the Type 1 driver and delegate the rest
+      of the work to it by calling FT_Open_Face().  (XXX TODO: after this
+      has been done, the kerning data from the FOND resource should be
+      appended to the face: On the Mac there are usually no AFM files
+      available.  However, this is tricky since we need to map Mac char
+      codes to ps glyph names to glyph ID's...)
+
+    - If there is a TrueType font (an `sfnt' resource), read it into memory,
+      wrap it into a memory stream, load the TrueType driver and delegate
+      the rest of the work to it, by calling FT_Open_Face().
+
+    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+      itself, even though it doesn't contains `POST' resources.  To handle
+      this special case without opening the file an extra time, we just
+      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+      available.

+# This file is designed for GNU Make, do not use it with another Make tool!
+#
+# It works as follows:
+#
+# - When invoked for the first time, this Makefile includes the rules found
+#   in `PROJECT/builds/detect.mk'.  They are in charge of detecting the
+#   current platform.
+#
+#   A summary of the detection is displayed, and the file `config.mk' is
+#   created in the current directory.
+#
+# - When invoked later, this Makefile includes the rules found in
+#   `config.mk'.  This sub-Makefile defines some system-specific variables
+#   (like compiler, compilation flags, object suffix, etc.), then includes
+#   the rules found in `PROJECT/builds/PROJECT.mk', used to build the
+#   library.
+#
+# See the comments in `builds/detect.mk' and `builds/PROJECT.mk' for more
+# details on host platform detection and library builds.

+\`configure' configures FreeType 2.7.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'.  Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.

+
+<body>
+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2005
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib     - release build; single threaded
+    freetype271_D.lib   - debug build;   single threaded
+    freetype271MT.lib   - release build; multi-threaded
+    freetype271MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2008
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib     - release build; single threaded
+    freetype271_D.lib   - debug build;   single threaded
+    freetype271MT.lib   - release build; multi-threaded
+    freetype271MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2005
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
+compiles the following libraries from the FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib     - release build; single threaded
+    freetype271_D.lib   - debug build;   single threaded
+    freetype271MT.lib   - release build; multi-threaded
+    freetype271MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2008
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.vcproj</tt>, and Visual Studio, called <tt>freetype.sln</tt>.  It
+compiles the following libraries from the FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib     - release build; single threaded
+    freetype271_D.lib   - debug build;   single threaded
+    freetype271MT.lib   - release build; multi-threaded
+    freetype271MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+<h1>
+  FreeType&nbsp;2 Project Files for VS.NET&nbsp;2010 or newer
+</h1>
+
+<p>This directory contains a project file for Visual C++ (VS.NET&nbsp;2010
+or newer), named <tt>freetype.vcxproj</tt>, and Visual Studio, called
+<tt>freetype.sln</tt>.  It compiles the following libraries from the
+FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib    - release build
+    freetype271d.lib   - debug build
+    freetype271ST.lib  - release build; single threaded
+    freetype271STd.lib - debug build;   single threaded
+    freetype271MT.lib  - release build; multi-threaded
+    freetype271MTd.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Both Win32 and x64 builds are supported.</p>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs\vc2010</tt>
+directory.</p>
+
+<p>Customization of the FreeType library is done by editing the
+<tt>ftoptions.h</tt> header file in the top-level <tt>devel</tt> path.
+Alternatively, you may copy the file to another directory and change the
+include directory in <tt>freetype.users.props</tt>.</p>
+
+<p>To configure library dependencies like <em>zlib</em> and <em>libpng</em>,
+edit the <tt>freetype.users.props</tt> file in this directory.  It also
+simplifies automated (command-line) builds using <a
+href="http://msdn.microsoft.com/library/dd393574%28v=vs.100%29.aspx">msbuild</a>.</p>

+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.

+  FreeType&nbsp;2 Project Files for Visual&nbsp;C++ and VS.NET&nbsp;2005

+</title>
+
+<body>
+<h1>
+  FreeType&nbsp;2 Project Files for Visual&nbsp;C++ and VS.NET&nbsp;2005
+  (Pocket PC)
+</h1>
+
+<p>This directory contains project files for Visual C++, named
+<tt>freetype.dsp</tt>, and Visual Studio, called <tt>freetype.sln</tt> for
+the following targets:
+
+<ul>
+  <li>PPC/SP 2003 (Pocket PC 2003)</li>
+  <li>PPC/SP WM5 (Windows Mobile 5)</li>
+  <li>PPC/SP WM6 (Windows Mobile 6)</li>
+</ul>
+
+It compiles the following libraries from the FreeType 2.7.1 sources:</p>
+
+<ul>
+  <pre>
+    freetype271.lib     - release build; single threaded
+    freetype271_D.lib   - debug build;   single threaded
+    freetype271MT.lib   - release build; multi-threaded
+    freetype271MT_D.lib - debug build;   multi-threaded</pre>
+</ul>
+
+<p>Be sure to extract the files with the Windows (CR+LF) line endings.  ZIP
+archives are already stored this way, so no further action is required.  If
+you use some <tt>.tar.*z</tt> archives, be sure to configure your extracting
+tool to convert the line endings.  For example, with <a
+href="http://www.winzip.com">WinZip</a>, you should activate the <em>TAR
+file smart CR/LF Conversion</em> option.  Alternatively, you may consider
+using the <tt>unix2dos</tt> or <tt>u2d</tt> utilities that are floating
+around, which specifically deal with this particular problem.
+
+<p>Build directories are placed in the top-level <tt>objs</tt>
+directory.</p>

+
+CHANGES BETWEEN 2.7 and 2.7.1
+
+  I. IMPORTANT CHANGES
+
+    - Support for the new CFF2 font format as introduced with OpenType
+      1.8 has been contributed by Dave Arnolds from Adobe.
+
+    - Preliminary support for variation fonts as specified in OpenType
+      1.8 (in addition to the  already existing support for Adobe's MM
+      and Apple's  GX formats).  Dave Arnolds  contributed handling of
+      advance  width change  variation;  more will  come  in the  next
+      version.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - Handling of  raw CID fonts was partially  broken (bug introduced
+      in 2.6.4).
+
+
+  III. MISCELLANEOUS
+
+    - Some limits for TrueType  bytecode execution have been tightened
+      to  speed   up  FreeType's  handling  of   malformed  fonts,  in
+      particular to quickly abort endless loops.
+
+      - The  number of  twilight points  can no  longer be  set to  an
+        arbitrarily large value.
+
+      - The total number of jump  opcode instructions (like JMPR) with
+        negative arguments  is dynamically restricted; the  same holds
+        for the total number of iterations in LOOPCALL opcodes.
+
+      The dynamic limits are based on  the number of points in a glyph
+      and the number of CVT entries.  Please report if you encounter a
+      font where the selected values are not adequate.
+
+    - PCF family names are made more `colourful'; they now include the
+      foundry  and information  whether they contain  wide characters.
+      For example,  you no longer get `Fixed' but  rather `Sony Fixed'
+      or `Misc Fixed Wide'.
+
+    - A new  function `FT_Get_Var_Blend_Coordinates'  (with its  alias
+      name  `FT_Get_MM_Blend_Coordinates') to retrieve the  normalized
+      blend  coordinates of the currently  selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new  function `FT_Get_Var_Design_Coordinates' to  retrieve the
+      design coordinates of the  currently selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
+      information without loading the (embedded) bitmap itself.
+
+    - Retrieving   advance   widths   from   bitmap   strikes   (using
+      `FT_Get_Advance' and `FT_Get_Advances') have been sped up.
+
+    - The  usual round  of  fuzzer fixes  to  better reject  malformed
+      fonts.
+
+    - The `ftmulti' demo program can now switch engines with key `H'.
+
+    - The  `ftstring'  demo  program   can  now  show  some  built-in,
+      non-latin sample strings (to be selected with the TAB key).
+
+    - The  `ftview'  demo program  can  now  switch between  a  font's
+      charmaps using the TAB key.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.5 and 2.7
+
+  I. IMPORTANT CHANGES
+
+    - As announced earlier, the 2.7.x series now uses the new subpixel
+      hinting  mode as  the  default, emulating  a  modern version  of
+      ClearType.
+
+      This change inevitably leads to different rendering results, and
+      you   might   change   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
+      configuration option to  adapt it to your taste (or  use the new
+      `FREETYPE_PROPERTIES'    environment    variable).    See    the
+      corresponding entry  below for  version 2.6.4, which  gives more
+      information.
+
+    - A new option  `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
+      introduced.   If  set (which  is  the  default), an  environment
+      variable  `FREETYPE_PROPERTIES' can  be used  to control  driver
+      properties.  Example:
+
+        FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
+                            cff:no-stem-darkening=1 \
+                            autofitter:warping=1
+
+      This allows to select, say, the subpixel hinting mode at runtime
+      for a given application.  See file `ftoption.h' for more.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - After  loading a  named instance  of  a GX  variation font,  the
+      `face_index'  value  in  the returned  `FT_Face'  structure  now
+      correctly holds the named instance  index in the upper 16bits as
+      documented.
+
+
+  III. MISCELLANEOUS
+
+    - A new macro `FT_IS_NAMED_INSTANCE' to  test whether a given face
+      is a named instance.
+
+    - More fixes to GX font handling.
+
+    - Apple's   `GETVARIATION'  bytecode   operator  (needed   for  GX
+      variation font support) has been implemented.
+
+    - Another round  of fuzzer fixes,  mainly to reject  invalid fonts
+      faster.
+
+    - Handling of raw CID fonts  was broken (bug introduced in version
+      2.6.4).
+
+    - The smooth rasterizer has been streamlined  to make it faster by
+      approx. 20%.
+
+    - The `ftgrid'  demo program now  understands command  line option
+      `-d' to give start-up design coordinates.
+
+    - The `ftdump' demo program has  a new command line option `-p' to
+      dump TrueType bytecode instructions.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.4 and 2.6.5
+
+  I. IMPORTANT BUG FIXES
+
+    - Compilation works again  on Mac OS X (bug introduced  in version
+      2.6.4).
+
+
+  II. IMPORTANT CHANGES
+
+    - The new  subpixel hinting  mode is now  disabled by  default; it
+      will  be enabled  by default  in the  forthcoming 2.7.x  series.
+      Main reason for reverting this feature is the principle of least
+      surprise: a  sudden change in  appearance of all fonts  (even if
+      the rendering improves  for almost all recent  fonts) should not
+      be expected in a new micro version of a series.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.3 and 2.6.4
+
+  I. IMPORTANT CHANGES
+
+    - A new  subpixel hinting  mode has  been contributed  by Nikolaus
+      Waxweiler, which is now the  default rendering mode for TrueType
+      fonts.  It implements  (almost everything of) version  40 of the
+      bytecode engine.
+
+      The existing code  base in FreeType (the  `Infinality code') was
+      stripped to the bare minimum  and all configurability removed in
+      the  name  of speed  and  simplicity.   The configurability  was
+      mainly aimed  at legacy  fonts like Arial,  Times New  Roman, or
+      Courier.  [Legacy fonts are fonts  that modify vertical stems to
+      achieve clean black-and-white bitmaps.]  The new mode focuses on
+      applying a minimal set of rules to all fonts indiscriminately so
+      that modern and web fonts  render well while legacy fonts render
+      okay.
+
+      Activation  of the  subpixel hinting  support can  be controlled
+      with   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'   configuration
+      option  at compile  time: If  set to  value 1,  you get  the old
+      Infinality  mode  (which  was  never  the  default  due  to  its
+      slowness).  Value 2 activates the new subpixel hinting mode, and
+      value 3 activates both.  The default is value 2.
+
+      At run time,  you can select the subpixel hinting  mode with the
+      `interpreter-version'  property (provided  you have  compiled in
+      the corresponding hinting mode); see `ftttdrv.h' for more.
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi,
+        Malayalam, Sinhala, Tamil
+
+
+  II. MISCELLANEOUS
+
+    - Type 42 fonts as created by LilyPond are now supported.
+
+    - Minor rendering improvments in the auto-hinter.
+
+    - For experimental  reasons, the old  CFF engine now  supports all
+      CFF operators except `random', including the deprecated Multiple
+      Masters  instructions.  This  allows the  display of  fonts like
+      `ITCGaramondMM-It.otf' (without font variations, though).
+
+    - Another round of fixes to improve handling of invalid fonts.
+
+    - The `ftgrid' demo program now displays the rendered pixels also;
+      this can be switched off with the `b' key.  Selection of various
+      LCD filtering modes can be done with the `L' key.
+
+    - The demo programs  have been extended to allow  selection of all
+      available TrueType bytecode engines.
+
+    - A very early beta version of a new, Qt based demo program called
+      `ftinspect'  is  part  of  the   source  code  bundle;  it  will
+      eventually supersede  the other  demo programs.   Currently, you
+      have to compile  it manually with `qmake; make';  note that many
+      features are still missing.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.2 and 2.6.3
+
+  I. IMPORTANT CHANGES
+
+    - Khmer,  Myanmar, Bengali,  and Kannada  script support  has been
+      added to the auto-hinter.
+
+
+  II. MISCELLANEOUS
+
+    - Better  support of  Indic  scripts like  Devanagari  by using  a
+      top-to-bottom hinting flow.
+
+    - All  FreeType macros  starting  with two  underscores have  been
+      renamed to  avoid a violation of  both the C and  C++ standards.
+      Example: Header  macros of the  form `__FOO_H__' are  now called
+      `FOO_H_'.  In most cases,  this should be completely transparent
+      to the user.   The exception to this  is `__FTERRORS_H__', which
+      must be  sometimes undefined by  the user to get  FreeType error
+      strings:  Both this  form and  the new  `FTERRORS_H_' macro  are
+      accepted for backwards compatibility.
+
+    - Minor improvements mainly to the Type 1 driver.
+
+    - The  new CFF  engine now  supports all  Type 2  operators except
+      `random'.
+
+    - The macro `_STANDALONE_', used for  compiling the B/W and smooth
+      rasterizers  as   stand-alone  modules,  has  been   renamed  to
+      `STANDALONE_', since macro names starting with an underscore and
+      followed by an uppercase letter are reserved in both C and C++.
+
+    - Function  `FT_Library_SetLcdFilterWeights'  now  also  activates
+      custom LCD filter weights (instead of just adjusting them).
+
+    - Support for  `unpatented hinting'  has been  completely removed:
+      Consequently,  the two  functions `FT_Face_CheckTrueTypePatents'
+      and  `FT_Face_SetUnpatentedHinting'  now  return  always  false,
+      doing nothing.
+
+    - The `ftgamma' demo  program has been modernized;  the gamma grid
+      display has been moved from `ftview' to this program.
+
+    - In `ftview',  it is now possible to cycle through  the available
+      LCD filtering modes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.1 and 2.6.2
+
+  I. IMPORTANT CHANGES
+
+    - The auto-hinter now supports stem darkening, to be controlled by
+      the    new   `no-stem-darkening'    and   `darkening-parameters'
+      properties.   This is  an  experimental  feature contributed  by
+      Nikolaus Waxweiler, and  the interface might change  in a future
+      release.
+
+    - By default, stem darkening is now switched off (for both the CFF
+      engine and the  auto-hinter).  The main reason is  that you need
+      linear  alpha  blending  and  gamma correction  to  get  correct
+      rendering results, and  the latter is not yet  available in most
+      freely  available  rendering  stacks like  X11.   Applying  stem
+      darkening without proper gamma correction  leads to far too dark
+      rendering results.
+
+    - The   meaning  of   `FT_RENDER_MODE_LIGHT'  has   been  slightly
+      modified.   It  now  essentially  means `no  hinting  along  the
+      horizontal  axis'; in  particular,  no change  of glyph  advance
+      widths.  Consequently, the auto-hinter  is used for all scalable
+      font  formats  except  for  CFF.    It  is  planned  that  other
+      font-specific rendering engines (TrueType, Type 1) will follow.
+
+
+  II. MISCELLANEOUS
+
+    - The default  LCD filter  has been changed  to be  normalized and
+      color-balanced.
+
+    - For    better    compatibility   with    FontConfig,    function
+      `FT_Library_SetLcdFilter'  accepts   a  new   enumeration  value
+      `FT_LCD_FILTER_LEGACY1'   (which  has   the   same  meaning   as
+      `FT_LCD_FILTER_LEGACY').
+
+    - A large number of bugs have been detected by using the libFuzzer
+      framework,  which should  further  improve  handling of  invalid
+      fonts.  Thanks again to Kostya Serebryany and Bungeman!
+
+    - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES',  a   new  configuration
+      option, controls the maximum number of executed opcodes within a
+      bytecode program.  You don't want to change this except for very
+      special  situations (e.g.,  making a  library fuzzer  spend less
+      time to handle broken fonts).
+
+    - The smooth renderer has been made faster.
+
+    - The `ftstring'  demo program  now supports  sub-pixel rendering;
+      use key `l' to cycle through the LCD modes.
+
+    - The `ftstring'  demo program now supports  colour rendering; use
+      the `space' key to cycle through various colour combinations.
+
+    - The graphical demo programs now use a default gamma value of 1.8
+      (instead of 1.2).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6 and 2.6.1
+
+  I. IMPORTANT BUG FIXES
+
+    - It turned  out that for CFFs  only the advance widths  should be
+      taken from the  `htmx' table, not the side  bearings.  This bug,
+      introduced in  version 2.6.0, makes  it necessary to  upgrade if
+      you are using  CFFs; otherwise, you get cropped  glyphs with GUI
+      interfaces like GTK or Qt.
+
+    - Accessing Type 42 fonts returned  incorrect results if the glyph
+      order of the embedded TrueType font differs from the glyph order
+      of the Type 42 charstrings table.
+
+
+  II. IMPORTANT CHANGES
+
+    - The header  file layout  has been  changed (again),  moving  all
+      header files except `ft2build.h' into a subdirectory tree.
+
+      Doing so  reduces the  possibility of  header file  name clashes
+      (e.g., FTGL's  `FTGlyph.h' with FreeType's `ftglyph.h')  on case
+      insensitive file systems like Mac OS X or Windows.
+
+      Applications  that  use  (a)  the  `freetype-config'  script  or
+      FreeType's `freetype2.pc' file for pkg-config to get the include
+      directory  for the  compiler,  and (b)  the  documented way  for
+      header inclusion like
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+        ...
+
+      don't need any change to the source code.
+
+    - Simple access  to named instances  in GX variation fonts  is now
+      available (in addition to the  previous method via FreeType's MM
+      interface).   In  the `FT_Face'  structure,  bits  16-30 of  the
+      `face_index' field hold the current named instance index for the
+      given face  index, and bits  16-30 of `style_flags'  contain the
+      number of  instances for  the given face  index.  `FT_Open_Face'
+      and friends also understand the  extended bits of the face index
+      parameter.
+
+      You need to enable  TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new
+      feature.  Otherwise, bits  16-30 of the two fields  are zero (or
+      are ignored).
+
+    - Lao script support has been added to the auto-hinter.
+
+
+  III. MISCELLANEOUS
+
+    - The auto-hinter's Arabic script support has been enhanced.
+
+    - Superscript-like and  subscript-like glyphs  as used  by various
+      phonetic alphabets like the IPA  are now better supported by the
+      auto-hinter.
+
+    - The TrueType bytecode interpreter now runs slightly faster.
+
+    - Improved support for builds with cmake.
+
+    - The  function  `FT_CeilFix'  now   always  rounds  towards  plus
+      infinity.
+
+    - The  function  `FT_FloorFix'  now always  rounds  towards  minus
+      infinity.
+
+    - A  new load  flag `FT_LOAD_COMPUTE_METRICS'  has been  added; it
+      makes FreeType  ignore pre-computed  metrics, as needed  by font
+      validating  or  font  editing  programs.  Right  now,  only  the
+      TrueType  module supports  it  to ignore  data  from the  `hdmx'
+      table.
+
+    - Another round of bug fixes  to better handle broken fonts, found
+      by Kostya Serebryany <kcc@google.com>.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.5 and 2.6
+
+  I. IMPORTANT CHANGES
+
+    - Behdad  Esfahbod contributed  code  for improved  thread-safety,
+      which results in the following model.
+
+      * An `FT_Face' object can only be safely used from one thread at
+        a time.
+
+      * An `FT_Library'  object can  now be used  without modification
+        from multiple threads at the same time.
+
+      * `FT_Face' creation and destruction  with the same `FT_Library'
+        object can only be done from one thread at a time.
+
+      One can use a single  `FT_Library' object across threads as long
+      as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'.
+      Any calls to `FT_Load_Glyph' and similar API are safe and do not
+      need the lock  to be held as  long as the same  `FT_Face' is not
+      used from multiple threads at the same time.
+
+    - Thai script support has been added to the auto-hinter.
+
+    - Arabic script support has been added to the auto-hinter.
+
+    - Following OpenType version 1.7,  advance widths and side bearing
+      values in  CFFs (wrapped  in an SFNT  structure) are  now always
+      taken from the `hmtx' table.
+
+    - Following OpenType  version 1.7, the  PostScript font name  of a
+      CFF font (wrapped in an SFNT structure) is now always taken from
+      the `name'  table.  This is  also true for  OpenType Collections
+      (i.e., TTCs using  CFFs subfonts instead of TTFs),  where it may
+      have a significant difference.
+
+    - Fonts natively hinted for  ClearType are now supported, properly
+      handling selector index 3 of the INSTCTRL bytecode instruction.
+
+    - Major improvements to the GX TrueType variation font handling.
+
+
+  II. MISCELLANEOUS
+
+    - A new auto-hinter  property `warping' can switch on  and off the
+      warping code  if this  experimental feature  is compiled  in (by
+      defining  the AF_CONFIG_OPTION_USE_WARPER  configuration option;
+      by default  this option is  now enabled but warping  is switched
+      off).
+
+      The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature,
+      available   since  2006.    Warping   only   works  in   `light'
+      auto-hinting mode.   The idea of  the code is to  slightly scale
+      and  shift a  glyph  along the  non-hinted  dimension (which  is
+      usually the horizontal axis) so that as much of its segments are
+      aligned  (more or  less) to  the grid.   To find  out a  glyph's
+      optimal   scaling   and   shifting  value,   various   parameter
+      combinations are tried and scored.
+
+      See  file  `ftautoh.h' for  more;  the  demo programs  `ftdiff',
+      `ftview', and `ftgrid' can toggle warping with key `w'.
+
+    - Some  fields  in  the  `FTC_ImageTypeRec'  structure  have  been
+      changed from signed to unsigned  type, which better reflects the
+      actual usage.  It is also an additional means to protect against
+      malformed input.
+
+      This  change doesn't  break  the ABI;  however,  it might  cause
+      compiler warnings.
+
+    - Function `FT_Bitmap_New'  has been renamed  to `FT_Bitmap_Init',
+      since  this name  better reflects  its function.   For backwards
+      compatibility, the old function name is still available.
+
+    - Function   `FT_Get_X11_Font_Format'   has    been   renamed   to
+      `FT_Get_Font_Format',  since  this   name  better  reflects  its
+      function.  For backwards compatibility, the old function name is
+      still available.
+
+      Additionally, the header  file macro for this  function has been
+      renamed to  `FT_FONT_FORMATS_H' (the old name  `FT_XFREE86_H' is
+      retained for backwards compatibility).
+
+    - Various improvements to the `ftgrid' demo program.
+
+      . It  can  now  display  GX and  MM  fonts  while  interactively
+        manipulating the axes (with keys F2, F3, and F4).
+
+      . Anti-aliasing rendering  modes can now be  selected (with keys
+        F5 and F6).
+
+      . The display of point numbers can be toggled with key `D'.
+
+    - Various improvements to the `ftdump' demo program.
+
+      . It now displays information on MM and GX variation axes.
+
+      . New  command line option  `-u' makes  it output data  in utf-8
+        encoding.
+
+    - The `ftmulti'  demo program can  now handle up  to six MM  or GX
+      axes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.4 and 2.5.5
+
+  I. IMPORTANT BUG FIXES
+
+    - Handling of  uncompressed PCF files works again (bug  introduced
+      in version 2.5.4).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.3 and 2.5.4
+
+  I. IMPORTANT BUG FIXES
+
+    - A   variant  of   vulnerability  CVE-2014-2240   was  identified
+      (cf.  http://savannah.nongnu.org/bugs/?43661) and  fixed in  the
+      new CFF driver.  All users should upgrade.
+
+    - The new auto-hinter code using HarfBuzz crashed for some invalid
+      fonts.
+
+    - Many fixes to better protect against malformed input.
+
+
+  II. IMPORTANT CHANGES
+
+    - Full auto-hinter support of the Devanagari script.
+
+    - Experimental auto-hinter support of the Telugu script.
+
+    - CFF stem darkening behaviour can now be controlled at build time
+      using the eight macros
+
+        CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4}    .
+
+    - Some fields in the `FT_Bitmap'  structure have been changed from
+      signed to unsigned type, which better reflects the actual usage.
+      It  is also  an additional  means to  protect against  malformed
+      input.
+
+      This  change doesn't  break  the ABI;  however,  it might  cause
+      compiler warnings.
+
+
+  III. MISCELLANEOUS
+
+    - Improvements to  the auto-hinter's algorithm to  recognize stems
+      and local extrema.
+
+    - Function `FT_Get_SubGlyph_Info' always returned an error even in
+      case of success.
+
+    - Version  2.5.1 introduced  major bugs  in  the cjk  part of  the
+      auto-hinter, which are now fixed.
+
+    - The  `FT_Sfnt_Tag'  enumeration  values  have  been  changed  to
+      uppercase,  e.g.  `FT_SFNT_HEAD'.   The lowercase  variants  are
+      deprecated.    This  is   for  orthogonality   with  all   other
+      enumeration (and enumeration-like) values in FreeType.
+
+    - `cmake' now supports builds of FreeType as an OS X framework and
+      for iOS.
+
+    - Improved project files for vc2010, introducing a property file.
+
+    - The  documentation generator  for  the API  reference  has  been
+      updated to produce  better HTML code (with proper  CSS).  At the
+      same time, the documentation got a better structure.
+
+    - The FT_LOAD_BITMAP_CROP flag is obsolete;  it is not used by any
+      driver.
+
+    - The  TrueType  DELTAP[123]  bytecode instructions  now  work  in
+      subpixel hinting  mode as described in  the ClearType whitepaper
+      (i.e., for touched points in the non-subpixel direction).
+
+    - Many small improvements to the internal arithmetic routines.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.2 and 2.5.3
+
+  I. IMPORTANT BUG FIXES
+
+    - A vulnerability (CVE-2014-2240) was  identified and fixed in the
+      new  CFF  driver  (cf.  http://savannah.nongnu.org/bugs/?41697).
+      All users should upgrade.
+
+    - More  bug  fixes related  to  correct  positioning of  composite
+      glyphs.
+
+    - Many fixes to better protect against malformed input.
+
+
+  II. IMPORTANT CHANGES
+
+    - FreeType can now use the HarfBuzz library to greatly improve the
+      auto-hinting of  fonts that  use OpenType features:  Many glyphs
+      that are part  of such features but don't have  cmap entries are
+      now handled  properly, for  example small caps  or superscripts.
+      Define the configuration  macro FT_CONFIG_OPTION_USE_HARFBUZZ to
+      activate HarfBuzz support.
+
+      You need HarfBuzz version 0.9.19 or newer.
+
+      Note that HarfBuzz depends on  FreeType; this currently causes a
+      chicken-and-egg problem  that can be  solved as follows  in case
+      HarfBuzz is not yet installed on your system.
+
+        1. Compile  and  install  FreeType without  the  configuration
+           macro FT_CONFIG_OPTION_USE_HARFBUZZ.
+
+        2. Compile and install HarfBuzz.
+
+        3. Define  macro  FT_CONFIG_OPTION_USE_HARFBUZZ, then  compile
+           and install FreeType again.
+
+      With FreeType's  `configure' script the procedure  boils down to
+      configure, build, and install Freetype, then configure, compile,
+      and  install  HarfBuzz,  then configure,  compile,  and  install
+      FreeType again (after executing `make distclean').
+
+    - All  libraries FreeType  depends on  are now  checked using  the
+      `pkg-config' configuration files  first, followed by alternative
+      methods.
+
+    - The  new  value  `auto'  for the  various  `--with-XXX'  library
+      options   (for   example   `--with-harfbuzz=auto')   makes   the
+      `configure' script automatically link to the libraries it finds.
+      This is now the default.
+
+    - In case FreeType's `configure' script  can't find a library, you
+      can  pass environment  variables to  circumvent pkg-config,  and
+      those variables  have been  harmonized as  a consequence  of the
+      changes mentioned above:
+
+        LIBZ           -> removed; use LIBZ_CFLAGS and LIBZ_LIBS
+        LIBBZ2         -> removed; use BZIP2_CFLAGS and BZIP2_LIBS
+        LIBPNG_LDFLAGS -> LIBPNG_LIBS
+
+      `./configure --help' shows all available environment variables.
+
+    - The `freetype-config'  script now understands  option `--static'
+      to emit static linking information.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5.1 and 2.5.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Improving the display of some broken TrueType fonts introduced a
+      bug  that made  FreeType crash  on some  popular (but  not fully
+      conformant) fonts like `ahronbd.ttf'.
+
+    - Another round of improvements to correct positioning and hinting
+      of composite glyphs in TrueType fonts.
+
+
+  II. MISCELLANEOUS
+
+    - Version  2.5.1  introduced a  bug  in  handling embedded  bitmap
+      strikes of  TrueType fonts,  causing garbage display  under some
+      circumstances.
+
+    - The   `ftgrid'   demo   program    couldn't   be   compiled   in
+      non-development builds.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.5 and 2.5.1
+
+  I. IMPORTANT BUG FIXES
+
+    - For  some WinFNT  files,  the last  glyph  wasn't displayed  but
+      incorrectly marked as invalid.
+
+    - The vertical size of glyphs was  incorrectly set after a call to
+      `FT_GlyphSlot_Embolden', resulting in clipped glyphs.
+
+    - Many fields of the `PCLT' table in SFNT based fonts (if accessed
+      with `FT_Get_Sfnt_Table') were computed incorrectly.
+
+    - In TrueType fonts,  hinting of composite glyphs  could sometimes
+      deliver  incorrect positions  of  components or  even  distorted
+      shapes.
+
+
+  II. IMPORTANT CHANGES
+
+    - WOFF font format support has been added.
+
+    - The auto-hinter now supports Hebrew.  Greek and Cyrillic support
+      has been improved.
+
+    - Support for the forthcoming `OS/2'  SFNT table version 5, as can
+      be found e.g. in the `Sitka' font family for Windows 8.1.
+
+    - The header  file layout  has been changed.   After installation,
+      all files are now located in `<prefix>/include/freetype2'.
+
+      Applications  that  use   (a)  `freetype-config'  or  FreeType's
+      `pkg-config' file to get the include directory for the compiler,
+      and (b) the documented way for header inclusion like
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+        ...
+
+      don't need any change to the source code.
+
+
+  III. MISCELLANEOUS
+
+    - The stem  darkening feature  of the  new CFF  engine can  now be
+      fine-tuned with the new `darkening-parameters' property.
+
+    - `ftgrid' has been updated to toggle various engines with the `H'
+      key, similar to `ftview' and `ftdiff'.
+
+    - The functionality of `ttdebug' has been greatly enhanced.
+
+      . It now displays twilight, storage, and control value data; key
+        `T' shows the twilight point  table, key `S' the storage data,
+        and key `C' the control value table.
+
+      . Some  keys  have  been  reassigned  from  lowercase  to  their
+        uppercase equivalents; for example `q'  to quit the program is
+        now `Q'.
+
+      . Key `f' finishes the current function.
+
+      . Key `R' restarts the debugger.
+
+      . Keys `b' and `p' set a breakpoint.
+
+      . Key `B' provides a function call backtrace.
+
+    - Better support of ARMv7 and x86_64 processors.
+
+    - Apple's `sbix' color bitmap format is now supported.
+
+    - Improved   auto-hinter  rendering   for  many   TrueType  fonts,
+      especially in the range 20-40ppem.
+
+    - A  new face  flag  `FT_FACE_FLAG_COLOR' has  been  added (to  be
+      accessed with the macro `FT_HAS_COLOR').
+
+    - `FT_Gzip_Uncompress'   (modeled    after   zlib's   `uncompress'
+      function)  has been  added; this  is a  by-product of  the newly
+      added WOFF support.
+
+    - Support for  a build with  `cmake' has been contributed  by John
+      Cary <cary@txcorp.com>.
+
+    - Support for x64  builds with Visual C++ has  been contributed by
+      Kenneth Miller <kennethadammiller@yahoo.com>
+
+    - Manual pages for most demo programs have been added.
+
+    - The GETINFO bytecode instruction for TrueType fonts was buggy if
+      used to retrieve subpixel hinting information.  It was necessary
+      to set  selector bit 6  to get  results for selector  bits 7-10,
+      which is wrong.
+
+    - Improved computation  of emulated vertical metrics  for TrueType
+      fonts.
+
+    - Fixed horizontal start-up position of vertical phantom points in
+      TrueType bytecode.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.12 and 2.5
+
+  I. IMPORTANT BUG FIXES
+
+    - The cache manager function `FTC_Manager_Reset'  didn't flush the
+      cache.
+
+
+  II. IMPORTANT CHANGES
+
+    - Behdad Esfahbod  (on behalf  of Google) contributed  support for
+      color embedded bitmaps (eg. color emoji).
+
+      A  new  load  flag,  FT_LOAD_COLOR, makes  FreeType  load  color
+      embedded-bitmaps, following this draft specification
+
+        https://color-emoji.googlecode.com/git/specification/v1.html
+
+      which defines two new SFNT  tables, `CBDT' and `CBLC' (named and
+      modeled  after  `EBDT'  and `EBLC',  respectively).   The  color
+      bitmaps  are  stored in  the  new  FT_PIXEL_MODE_BGRA format  to
+      represent BGRA  pre-multiplied sRGB  images.  If PNG  support is
+      available,  PNG color  images as  defined in  the same  proposed
+      specification are supported also.
+
+      Note that  color bitmaps  are converted  to grayscale  if client
+      didn't ask for color.
+
+    - As  announced in  the  previous release,  the  old FreeType  CFF
+      engine  is now  disabled by  default.  It  can be  conditionally
+      compiled     by     defining     the     configuration     macro
+      CFF_CONFIG_OPTION_OLD_ENGINE.
+
+    - As announced in the previous release,  all code related to macro
+      FT_CONFIG_OPTION_OLD_INTERNALS  has been removed,  thus becoming
+      obsolete.
+
+
+  III. MISCELLANEOUS
+
+    - The  property API  (`FT_Property_Get' and  `FT_Property_Set') is
+      now declared as stable.
+
+      The  exception,   however,  are  the   experimental  auto-hinter
+      properties `glyph-to-script-map' and `fallback-script' which are
+      subject to change in a forthcoming release.
+
+    - `ftview' has been updated to  support color embedded bitmaps; it
+      can be toggled on and off  with key `c'.  The small cache toggle
+      is now key `K'.
+
+    - It  is now  possible  to  control the  version  of the  TrueType
+      hinting engine  using the new `interpreter-version'  property of
+      the  `truetype' module:  Versions 35  and 38  (the default)  are
+      supported,  which  roughly  corresponds to  disable  and  enable
+      subpixel hinting support, respectively.
+
+      In  both  `ftview'  and  `ftdiff',  switching  between  the  two
+      versions  can be  done  with  key `H'.   In  the `ftbench'  demo
+      program, command line option `-H'  has been extended to activate
+      the non-default interpreter version.
+
+    - The `ttdebug' program has been further improved.  In particular,
+      it accepts a new command line  option `-H' to select the hinting
+      engine.
+
+    - `ftdump's verbose option has been renamed to `-V'.  For all demo
+      programs, `-v' now shows version information.
+
+    - Another round of TrueType subpixel hinting fixes.
+
+    - The `apinames' tool can now create an import file for NetWare.
+
+    - 64bit compilation of the new CFF engine was buggy.
+
+    - Some fixes to improve robustness in memory-tight situations.
+
+

+      Arnold <darnold@adobe.com>,  this work  has been  contributed by
+      Adobe in  collaboration with Google.   It is vastly  superior to
+      the old CFF engine, and it  will replace it in the next release.
+      Right  now,  it  is  still  off by  default,  and  you  have  to
+      explicitly select it using  the new `hinting-engine' property of
+      the cff driver:
+
+        ...
+        #include FT_MODULE_H
+        #include FT_CFF_DRIVER_H
+
+        FT_Library  library;
+        int         engine = FT_CFF_HINTING_ADOBE;
+
+
+        ...
+        FT_Property_Set( library, "cff", "hinting-engine", &engine );
+
+      The code has  a (mature) beta status; we encourage  all users to
+      test it and report any problems.
+
+      In case you want to activate the new CFF engine unconditionally,
+      apply this patch:

+
+    - The  macro FT_CONFIG_OPTION_OLD_INTERNALS  is no  longer set  by
+      default.  In  the next  release, we  will completely  remove the
+      associated code.   Please update your  programs in case  you are
+      still using this macro.
+
+
+  II. MISCELLANEOUS
+
+    - The  (top-level)  `configure'  script   now  respects  the  MAKE
+      environment variable to specify a `make' binary.   For backwards
+      compatibility, GNUMAKE still overrides MAKE, though.
+
+    - The `ftview'  and `ftdiff'  demo programs have  been redesigned,
+      showing  more options  permanently  on the  screen, among  other
+      minor improvements.
+
+    - Using the `H'  key, it is now possible to  select the CFF engine
+      in both `ftview' and `ftdiff'.
+
+    - The new command line option `-H' for `ftbench' selects the Adobe
+      CFF engine.
+
+    - It is  now possible  to directly select  the LCD  rendering mode
+      with the keys `A'-`F' in  `ftview'.  The key mapping for cycling
+      through LCD modes  has been changed from `K' and  `L' to `k' and
+      `l', and  toggling custom LCD  filtering is no longer  mapped to
+      key `F' but to key `L'.
+
+    - In `ftdiff',  key `x' toggles  between layout modes:  Either use
+      the  advance width  (this is  new and  now the  default) or  the
+      bounding box information to determine line breaks.
+
+    - For all demo  tools, the new command line option  `-v' shows the
+      version.
+
+    - For the demo tools with a GUI, the new command line options `-w'
+      and `-h' select  the width and the height of  the output window,
+      respectively.
+
+    - The `ttdebug' program was broken and has been reactivated.  Note
+      that this program is not compiled by default.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.10 and 2.4.11
+
+  I. IMPORTANT BUG FIXES
+
+    - Some vulnerabilities in the  BDF implementation have been fixed.
+      Users of this font format should upgrade.
+
+
+  II. IMPORTANT CHANGES
+
+    - Subpixel  hinting support  has been  contributed by  Infinality,
+      based on Greg Hitchcock's whitepaper at
+
+        http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+
+      Originally, it was a separate patch available from
+
+        http://www.infinality.net/blog/
+
+      and which has been integrated.
+
+      Note that  ClearType support is not  completely implemented!  In
+      particular,  full support  for the  options `compatible_widths',
+      `symmetrical_smoothing,  and  `bgr'  (via the  GETINFO  bytecode
+      instruction) is missing.
+
+      Activation of  subpixel hinting  support can be  controlled with
+      the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it
+      is switched off by default.  This feature is still experimental;
+      we welcome test reports!
+
+    - Support for OpenType collections (OTC) has been added.
+
+    - Pure CFF fonts within an SFNT wrapper are now supported.
+
+
+  III. MISCELLANEOUS
+
+    - Minor rendering improvements to the auto-hinter.
+
+    - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°.
+
+    - Experimental support  to handle `property modules',  for example
+      to control the  behaviour of the auto-hinter.   The API consists
+      of two new functions, `FT_Property_Set' and `FT_Property_Get'.
+
+      The code is  still subject to change and should  not be used for
+      production.
+
+    - The `ftdiff' demo program now supports UTF-8 encoded input files
+      for option `-f'.
+
+    - Using keys `r' and `R', you can now adjust the stroker radius in
+      the `ftview' demo program.
+
+    - Other, minor fixes and improvements.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.9 and 2.4.10
+
+  I. IMPORTANT BUG FIXES
+
+    - Incremental glyph loading as needed by ghostscript was broken.
+
+
+  II. MISCELLANEOUS
+
+    - A new  function `FT_Outline_EmboldenXY',  contributed by  Alexei
+      Podtelezhnikov.
+
+    - In the `ftview' demo program, key `e' has been replaced with `x'
+      and `y' to  embolden in  the horizontal and  vertical direction,
+      respectively.
+
+    - The glyph  spacing computation  in `FT_GlyphSlot_Embolden'  (and
+      similar code in `ftview') has been improved.
+
+    - Minor  improvements to  the TrueType  bytecode  interpreter  and
+      glyph loader, the auto-hinter, and the B/W rasterizer.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.8 and 2.4.9
+
+  I. IMPORTANT BUG FIXES
+
+    - Another round of fixes to better handle invalid fonts.   Many of
+      them are vulnerabilities  (see CVE-2012-1126 up to CVE-2012-1144
+      and SA48320) so all users should upgrade.
+
+
+  II. MISCELLANEOUS
+
+    - The `ENCODING -1 <n>' format of BDF fonts is now supported.
+
+    - For BDF fonts,  support for the whole Unicode encoding range has
+      been added.
+
+    - Better TTF support for x_ppem != y_ppem.
+
+    - `FT_Get_Advances' sometimes returned bogus values.
+
+    - The  demo  programs  no  longer  recognize  and  handle  default
+      suffixes; you now have to always specify the complete font name.
+
+    - Better rendering and LCD mode cycling added to `ftview'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.7 and 2.4.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Some vulnerabilities in handling CID-keyed PostScript fonts have
+      been fixed; see CVE-2011-3439.
+
+
+  II. MISCELLANEOUS
+
+    - Chris Liddell contributed a new API, `FT_Get_PS_Font_Value',  to
+      retrieve most of the dictionary keys in Type 1 fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.6 and 2.4.7
+
+  I. IMPORTANT BUG FIXES
+
+    - Some  vulnerabilities in handling Type 1 fonts  have been fixed;
+      see CVE-2011-3256.
+
+
+  II. MISCELLANEOUS
+
+    - FreeType  now properly  handles ZapfDingbats  glyph names  while
+      constructing a Unicode character map (for fonts which don't have
+      one).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.5 and 2.4.6
+
+  I. IMPORTANT BUG FIXES
+
+    - For TrueType based fonts, the ascender and descender values were
+      incorrect sometimes  (off by a pixel if the ppem value was not a
+      multiple of 5).   Depending on the use you might now  experience
+      a different  layout; the  change should  result in  better, more
+      consistent line spacing.
+
+    - Fix CVE-2011-0226  which causes a  vulnerability while  handling
+      Type 1 fonts.
+
+    - BDF fonts  containing  glyphs with negative values  for ENCODING
+      were  incorrectly  rejected.  This  bug has  been introduced  in
+      FreeType version 2.2.0.
+
+    - David Bevan contributed a major revision of the FreeType stroker
+      code:
+
+      . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+
+      . A new  line join style,  FT_STROKER_LINEJOIN_MITER_FIXED,  has
+        been introduced to support PostScript and PDF miter joins.
+
+      . FT_STROKER_LINEJOIN_MITER_VARIABLE  has been introduced  as an
+        alias for FT_STROKER_LINEJOIN_MITER.
+
+      . Various stroking glitches has been fixed.
+
+
+  II. MISCELLANEOUS
+
+      - SFNT bitmap fonts which contain an outline glyph for `.notdef'
+        only no longer set the FT_FACE_FLAG_SCALABLE flag.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.4 and 2.4.5
+
+  I. IMPORTANT BUG FIXES
+
+    - A rendering regression  for second-order Bézier curves  has been
+      fixed, introduced in 2.4.3.
+
+
+  II. IMPORTANT CHANGES
+
+    - If autohinting  is not  explicitly disabled,  FreeType now  uses
+      the autohinter if  a TrueType based font doesn't  contain native
+      hints.
+
+    - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH  has been made
+      redundant and  is simply ignored;  this means that FreeType  now
+      ignores the global advance width value in TrueType fonts.
+
+
+  III. MISCELLANEOUS
+
+    - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of
+      a font.
+
+    - Support for PCF files compressed with bzip2 has been contributed
+      by Joel  Klinghed.  To  make this  work, the  OS must  provide a
+      bzip2 library.
+
+    - Bradley  Grainger  contributed  project  and  solution  files in
+      Visual Studio 2010 format.
+
+    - Again some fixes to better handle broken fonts.
+
+    - Some improvements to the B/W rasterizer.
+
+    - Fixes to the cache module to improve robustness.
+
+    - Just  Fill Bugs contributed (experimental) code to compute  blue
+      zones for CJK Ideographs, improving the alignment of  horizontal
+      stems at the top or bottom edges.
+
+    - The `ftgrid' demo program  can now display  autohinter segments,
+      to be toggled on and off with key `s'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.3 and 2.4.4
+
+  I. IMPORTANT BUG FIXES
+
+    - UVS support (TrueType/OpenType cmap format 14) support is fixed.
+      This regression has been introduced in version 2.4.0.
+
+
+  II. MISCELLANEOUS
+
+    - Detect tricky fonts (e.g. MingLiU)  by the lengths and checksums
+      of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when
+      a TrueType font without family name is given.  The previous fix,
+      introduced in 2.4.3,  was too rigorous,  causing many  subsetted
+      fonts (mainly  from PDF files) displayed badly  because FreeType
+      forced  rendering with  the TrueType bytecode engine  instead of
+      the autohinter.
+
+    - Better support for 64bit platforms.
+
+    - More fixes to improve handling of broken fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.2 and 2.4.3
+
+  I. IMPORTANT BUG FIXES
+
+    - Fix rendering of certain cubic, S-shaped arcs.   This regression
+      has been introduced in version 2.4.0.
+
+
+  II. MISCELLANEOUS
+
+    - To  fix  the  above  mentioned  rendering  issue,  a  new spline
+      flattening algorithm  has been  introduced which  speeds up both
+      conic and cubic arcs.
+
+    - Handling of broken fonts has been further improved.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.1 and 2.4.2
+
+  I. IMPORTANT BUG FIXES
+
+    - A stack overflow in CFF Type2 CharStrings interpreter is fixed.
+
+    - Handling Type 42 font deallocation was broken; additionally, the
+      library is now more robust against malformed Type 42 fonts.
+
+
+  II. MISCELLANEOUS
+
+    - Two new functions,  `FT_Reference_Library' (in FT_MODULE_H)  and
+      `FT_Reference_Face'  (in  FT_FREETYPE_H),  have  been  added  to
+      simplify life-cycle management.  A counter gets initialized to 1
+      at the  time an  FT_Library (or  FT_Face) structure  is created.
+      The  two  new   functions  increment  the  respective   counter.
+      `FT_Done_Library' and `FT_Done_Face' then only destroy a library
+      or face if the counter is 1, otherwise they simply decrement the
+      counter.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.4.0 and 2.4.1
+
+  I. IMPORTANT CHANGES
+
+    - A serious bug in the  CFF font module prevented  display of many
+      glyphs in CFF fonts like `MinionPro-Regular.otf'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.12 and 2.4.0
+
+  I. IMPORTANT CHANGES
+
+    - Since May  2010, all  patents  regarding  the TrueType  bytecode
+      interpreter have expired worldwide.  Consequently, we now define
+      TT_CONFIG_OPTION_BYTECODE_INTERPRETER by  default (and  undefine
+      TT_CONFIG_OPTION_UNPATENTED_HINTING).
+
+    - A new function `FT_Library_SetLcdFilterWeights' is available  to
+      adjust the filter weights set by `FT_Library_SetLcdFilter'.
+
+
+  II. MISCELLANEOUS
+
+    - Thanks to many reports from Robert Święcki, FreeType's stability
+      in handling broken or damaged fonts is much improved.
+
+    - Support  for LCD  filter  control has  been  added to  the  demo
+      programs `ftdiff' and `ftview'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.11 and 2.3.12
+
+  I. IMPORTANT CHANGES
+
+    - For  `FT_Open_Face',  new  parameters  are  available  to ignore
+      preferred family names: FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY and
+      FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY.
+
+
+  II. MISCELLANEOUS
+
+    - Support  for  incremental  font  loading  (controlled  with  the
+      FT_CONFIG_OPTION_INCREMENTAL macro) is now active by default.
+
+    - Better support for vertical metrics.
+
+    - Various minor bug fixes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.10 and 2.3.11
+
+  I. IMPORTANT BUG FIXES
+
+    - Version 2.3.10 broke PCF support.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.10 and 2.3.9
+
+  I. IMPORTANT BUG FIXES
+
+    - If all  ASCII digits in a  font have the  same (unscaled) width,
+      the autohinter respects this and won't change it.
+
+    - TrueType fonts  are now  rasterized correctly  if the horizontal
+      and vertical resolution differ.
+
+    - Type 1 fonts are now handled with increased precision internally
+      to avoid serious rounding issues if non-integral coordinates are
+      encountered.
+
+    - Horizontally  condensed CFF  fonts (using the font  matrix) were
+      rendered  incorrectly.   This  bug  has  been  introduced  after
+      release 2.3.5.
+
+
+  II. IMPORTANT CHANGES
+
+    - Support for the SFNT cmap 13 table format (as defined by the new
+      OpenType 1.6 specification) has been added.
+
+    - B/W rasterization  of well-hinted TrueType  fonts at small sizes
+      has been greatly improved.
+
+    - Calculation  of  vertical  metrics in  OpenType  fonts has  been
+      improved.
+
+
+  III. MISCELLANEOUS
+
+    - It  is now  possible to  change  the emboldening  factor in  the
+      `ftview' demo program with keys `e' and `E'.
+
+    - It is  now possible  to change the  slant value in  the `ftview'
+      demo program with keys `s' and `S'.
+
+    - The  5-levels  grayscale  mode of  the `ftraster'  module (which
+      FreeType doesn't use by default) was broken since version 2.3.0.
+
+    - Compilation of the  `ftgrays' and `ftraster' modules  was broken
+      in stand-alone mode.
+
+    - Various fixes for compilation on 64bit and 16bit architectures.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.9 and 2.3.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Very unfortunately, FreeType 2.3.8 contained a change that broke
+      its  official ABI.  The  end result  is  that programs  compiled
+      against previous versions of the library, but dynamically linked
+      to  2.3.8 can  experience  memory corruption  if  they call  the
+      `FT_Get_PS_Font_Info' function.
+
+      We recommend all users to  upgrade to 2.3.9 as soon as possible,
+      or to downgrade to a previous  release of the library if this is
+      not an option.
+
+      The  origin of the  bug is  that a  new field  was added  to the
+      publicly  defined  `PS_FontInfoRec'  structure.   Unfortunately,
+      objects of this  type can be stack or  heap allocated by callers
+      of   `FT_Get_PS_Font_Info',  resulting   in   a  memory   buffer
+      overwrite with its implementation in 2.3.8.
+
+      If  you want to  know whether  your code  is vulnerable  to this
+      issue,  simply  search  for  the  substrings  `PS_FontInfo'  and
+      `PS_Font_Info' in your source code.  If none is found, your code
+      is safe and is not affected.
+
+      The FreeType team apologizes for the problem.
+
+    - The POSIX support  of MacOS resource-fork fonts  (Suitcase fonts
+      and LaserWriter Type1 PostScript fonts) was broken in 2.3.8.  If
+      FreeType2 is built without Carbon framework, these fonts are not
+      handled correctly.  Version 2.3.7 didn't have this bug.
+
+    - `FT_Get_Advance' (and `FT_Get_Advances') returned bad values for
+      almost all font formats except TrueType fonts.
+
+    - Fix a bug  in the SFNT  kerning table  loader/parser which could
+      crash the engine if certain malformed tables were encountered.
+
+    - Composite SFNT bitmaps are now handled correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - The   new  functions   `FT_Get_CID_Is_Internally_CID_keyed'  and
+      `FT_Get_CID_From_Glyph_Index'  can be  used to  access CID-keyed
+      CFF fonts  via CID  values.  This code  has been  contributed by
+      Michael Toftdal.
+
+
+  III. MISCELLANEOUS
+
+    - `FT_Outline_Get_InsideBorder'  returns   FT_STROKER_BORDER_RIGHT
+      for empty outlines.  This was incorrectly documented.
+
+    - The `ftview' demo program now supports UTF-8 encoded strings.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.8 and 2.3.7
+
+  I. IMPORTANT BUG FIXES
+
+    - CID-keyed fonts in an SFNT wrapper were not handled correctly.
+
+    - The smooth renderer produced truncated images (on the right) for
+      outline parts with negative horizontal values.  Most fonts don't
+      contain outlines left  to the y coordinate axis, but  the effect
+      was very noticeable for outlines processed with FT_Glyph_Stroke,
+      using thick strokes.
+
+    - `FT_Get_TrueType_Engine_Type'  returned a  wrong  value if  both
+      configuration  macros  TT_CONFIG_OPTION_BYTECODE_INTERPRETER and
+      TT_CONFIG_OPTION_UNPATENTED_HINTING were defined.
+
+    - The  `face_index'  field  in   the  `FT_Face'  structure  wasn't
+      initialized properly after calling FT_Open_Face and friends with
+      a positive face index for CFFs,  WinFNTs, and, most importantly,
+      for TrueType Collections (TTCs).
+
+
+  II. IMPORTANT CHANGES
+
+    - Rudimentary support for Type 1  fonts and CID-keyed Type 1 fonts
+      in an SFNT wrapper has been  added -- such fonts are used on the
+      Mac.  The core  SFNT tables `TYP1' and `CID '  are passed to the
+      PS Type 1  and CID-keyed PS font drivers;  other tables (`ALMX',
+      `BBOX', etc.) are not supported yet.
+
+    - A  new interface  to extract  advance values  of glyphs  without
+      loading their outlines has been added.  The functions are called
+      `FT_Get_Advance' and `FT_Get_Advances'; they are defined in file
+      `ftadvanc.h' (to be accessed as FT_ADVANCES_H).
+
+    - A new function `FT_Get_FSType_Flags' (in FT_FREETYPE_H) has been
+      contributed  by   David  Bevan  to  access   the  embedding  and
+      subsetting restriction information of fonts.
+
+
+  III. MISCELLANEOUS
+
+    - FT_MulFix is now an inlined function; by default, assembler code
+      is provided for x86 and ARM.  See FT_CONFIG_OPTION_INLINE_MULFIX
+      and FT_CONFIG_OPTION_NO_ASSEMBLER (in ftoption.h) for more.
+
+    - The handling of `tricky' fonts  (this is, fonts which don't work
+      with the  autohinter, needing the font  format's hinting engine)
+      has been generalized and changed slightly:
+
+      . A new  face flag  FT_FACE_FLAG_TRICKY indicates that  the font
+        format's  hinting engine is  necessary for  correct rendering.
+        The macro FT_IS_TRICKY can be used to check this flag.
+
+      . FT_LOAD_NO_HINTING is now ignored for tricky fonts.  To really
+        force  raw  loading  of  such fonts  (without  hinting),  both
+        FT_LOAD_NO_HINTING  and FT_LOAD_NO_AUTOHINT  must  be used  --
+        this is something which you probably never want to do.
+
+      . Tricky  TrueType fonts  always use  the  bytecode interpreter,
+        either the patented or unpatented version.
+
+    - The  function  `FT_GlyphSlot_Own_Bitmap'  has  been  moved  from
+      FT_SYNTHESIS_H to FT_BITMAP_H; it  is now part of the `official'
+      API.   (The functions  in  FT_SYNTHESIS_H are  still subject  to
+      change, however.)
+
+    - In the  `ftdiff'  demo  program you  can now  toggle the  use of
+      FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH with key `a'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.7 and 2.3.6
+
+  I. IMPORTANT BUG FIXES
+
+    - If the library  was compiled on an i386  platform using gcc, and
+      compiler  option -O3 was  given, `FT_MulFix'  sometimes returned
+      incorrect  results   which  could  have   caused  problems  with
+      `FT_Request_Metrics'   and  `FT_Select_Metrics',   returning  an
+      incorrect descender size.
+
+    - Pure CFFs without  subfonts were scaled incorrectly  if the font
+      matrix  was  non-standard.  This  bug  has  been  introduced  in
+      version 2.3.6.
+
+    - The  `style_name'  field  in  the  `FT_FaceRec'  structure often
+      contained  a wrong  value for  Type 1  fonts.  This misbehaviour
+      has been  introduced  in  version  2.3.6  while  trying  to  fix
+      another   problem.   [Note,  however,   that   this   value   is
+      informative only  since  the  used  algorithm to  extract  it is
+      very simplistic.]
+
+
+  II. IMPORTANT CHANGES
+
+    - Two      new      macros,      FT_OUTLINE_SMART_DROPOUTS     and
+      FT_OUTLINE_EXCLUDE_STUBS,  have been introduced.   Together with
+      FT_OUTLINE_IGNORE_DROPOUTS (which  was ignored previously) it is
+      now possible to control the dropout mode  of the `raster' module
+      (for B&W rasterization),   using  the   `flags'  field   in  the
+      `FT_Outline' structure.
+
+    - The TrueType bytecode interpreter now passes the dropout mode to
+      the B&W rasterizer.  This greatly increases the output for small
+      ppem values of many fonts like `pala.ttf'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.6 and 2.3.5
+
+  I. IMPORTANT BUG FIXES
+
+    - A  bunch of  potential security  problems have  been found.  All
+      users should update.
+
+    - Microsoft  Unicode  cmaps  in  TrueType  fonts  are  now  always
+      preferred over Apple cmaps.  This is not a bug per se, but there
+      exist some buggy  fonts created for MS which  have broken  Apple
+      cmaps.  This affects  only the automatic  selection of FreeType;
+      it's always possible to manually select an Apple Unicode cmap if
+      desired.
+
+    - Many bug fixes to the TrueType bytecode interpreter.
+
+    - Improved Mac support.
+
+    - Subsetted CID-keyed CFFs are now supported correctly.
+
+    - CID-keyed CFFs with subfonts which are scaled in a  non-standard
+      way are now handled correctly.
+
+    - A call to FT_Open_Face with `face_index' < 0 crashed FreeType if
+      the font was a Windows (bitmap) FNT/FON.
+
+
+  II. IMPORTANT CHANGES
+
+    - The new function `FT_Get_CID_Registry_Ordering_Supplement' gives
+      access to  those fields in a CID-keyed font.  The code  has been
+      contributed by Derek Clegg.
+
+    - George Williams  contributed  code  to validate  the new  `MATH'
+      OpenType  table (within  the `otvalid'  module).  The  `ftvalid'
+      demo program has been extended accordingly.
+
+    - An API for cmap 14 support  (for Unicode Variant Selectors, UVS)
+      has been contributed by George Williams.
+
+    - A new face flag FT_FACE_FLAG_CID_KEYED has been added,  together
+      with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is
+      CID-keyed.
+
+
+  III. MISCELLANEOUS
+
+    - Build support for symbian has been contributed.
+
+    - Better WGL4 glyph name support, contributed by Sergey Tolstov.
+
+    - Debugging output of the  various FT_TRACEX macros is now sent to
+      stderr.
+
+    - The `ftview' demo program now provides artificial slanting too.
+
+    - The `ftvalid' demo  program has a new  option `-f' to select the
+      font index.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.5 and 2.3.4
+
+  I. IMPORTANT BUG FIXES
+
+    - Some subglyphs in TrueType fonts were handled incorrectly due to
+      a missing graphics state reinitialization.
+
+    - Large .Z files  (as distributed with some X11  packages) weren't
+      handled correctly, making FreeType increase the heap stack in an
+      endless loop.
+
+    - A large  number of  bugs have  been fixed  to avoid  crashes and
+      endless loops with invalid fonts.
+
+
+  II. IMPORTANT CHANGES
+
+    - The  two new  cache functions  `FTC_ImageCache_LookupScaler' and
+      `FTC_SBit_Cache_LookupScaler' have been added to allow lookup of
+      glyphs using an  `FTC_Scaler' object;  this makes it possible to
+      use fractional pixel sizes in the cache.  The demo programs have
+      been updated accordingly to use this feature.
+
+    - A new API  `FT_Get_CMap_Format' has been added to  get the  cmap
+      format  of a  TrueType font.   This  is useful  in handling  PDF
+      files.  The code has been contributed by Derek Clegg.
+
+    - The  auto-hinter  now  produces  better  output  by  default for
+      non-Latin scripts  like Indic.   This was done by  using the CJK
+      hinting module  as the default instead of the Latin one.  Thanks
+      to Rahul Bhalerao for this suggestion.
+
+    - A new API `FT_Face_CheckTrueTypePatents'  has been added to find
+      out  whether  a  given  TrueType  font  uses  patented  bytecode
+      instructions.   The  `ft2demos' bundle  contains a  new  program
+      called `ftpatchk' which demonstrates its usage.
+
+    - A  new  API  `FT_Face_SetUnpatentedHinting'  has  been  added to
+      enable or disable the unpatented hinter.
+
+    - Support for Windows FON files in PE format  has been contributed
+      by Dmitry Timoshkov.
+
+
+  III. MISCELLANEOUS
+
+    - Vincent Richomme contributed Visual C++ project files for Pocket
+      PCs.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.4 and 2.3.3
+
+  I. IMPORTANT BUG FIXES
+
+    - A serious  bug  in  the  handling  of bitmap  fonts (and  bitmap
+      strikes of outline fonts) has been introduced in 2.3.3.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.3 and 2.3.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Remove a serious regression in the TrueType bytecode interpreter
+      that was introduced  in version 2.3.2.  Note that  this does not
+      disable  the  improvements  introduced  to  the  interpreter  in
+      version 2.3.2,  only some ill  cases that occurred  with certain
+      fonts (though a few popular ones).
+
+    - The auto-hinter now  ignores single-point contours for computing
+      blue zones.   This bug  created `wavy' baselines  when rendering
+      text  with  various  fonts  that  use these  contours  to  model
+      mark-attach points  (these are points that  are never rasterized
+      and are placed outside of the glyph's real outline).
+
+    - The `rsb_delta' and `lsb_delta' glyph slot fields are now set to
+      zero for mono-spaced fonts.  Otherwise code that uses them would
+      essentially ruin the fixed-advance property.
+
+    - Fix  CVE-2007-1351 which  can  cause an  integer overflow  while
+      parsing  BDF fonts,  leading to  a potentially  exploitable heap
+      overflow condition.
+
+
+  II. MISCELLANEOUS
+
+    - Fixed compilation issues on some 64-bit platforms (see ChangeLog
+      for details).
+
+    - A new demo  program `ftdiff' has been added  to compare TrueType
+      hinting, FreeType's auto  hinting, and rendering without hinting
+      in three columns.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.2 and 2.3.1
+
+  I. IMPORTANT BUG FIXES
+
+    - FreeType  returned incorrect  kerning information  from TrueType
+      fonts when the bytecode  interpreter was enabled.  This happened
+      due to a typo introduced in version 2.3.0.
+
+    - Negative  kerning  values  from   PFM  files  are  now  reported
+      correctly  (they were read  as 16-bit  unsigned values  from the
+      file).
+
+    - Fixed  a small  memory leak  when `FT_Init_FreeType'  failed for
+      some reason.
+
+    - The Postscript hinter placed and sized very thin and ghost stems
+      incorrectly.
+
+    - The TrueType bytecode  interpreter has been fixed to  get rid of
+      most of the  rare differences seen in comparison  to the Windows
+      font loader.
+
+
+  II. IMPORTANT CHANGES
+
+    - The auto-hinter  now better deals  with serifs and  corner cases
+      (e.g.,  glyph '9'  in Arial  at 9pt,  96dpi).  It  also improves
+      spacing  adjustments and doesn't  change widths  for non-spacing
+      glyphs.
+
+    - Many   Mac-specific   functions   are  deprecated   (but   still
+      available);  modern replacements  have been  provided  for them.
+      See the documentation in file `ftmac.h'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.1 and 2.3.0
+
+  I. IMPORTANT BUG FIXES
+
+    - The TrueType interpreter sometimes returned incorrect horizontal
+      metrics due to a bug in the handling of the SHZ instruction.
+
+    - A typo  in  a  security  check  introduced  after  version 2.2.1
+      prevented FreeType to render some glyphs in CFF fonts.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.3.0 and 2.2.1
+
+  I. IMPORTANT BUG FIXES
+
+    - The  PCF font  loader  is  now much  more  robust while  loading
+      malformed font files.
+
+    - Various memory leaks have been found and fixed.
+
+    - The TrueType name loader now deals properly with some fonts that
+      encode their  names in UTF-16 (the specification  was vague, and
+      the code incorrectly assumed UCS-4).
+
+    - Fixed the TrueType bytecode  loader to deal properly with subtle
+      monochrome/gray  issues  when   scaling  the  CVT.   Some  fonts
+      exhibited bad rendering artifacts otherwise.
+
+    - `FT_GlyphSlot_Embolden' now  supports vertical layouts correctly
+      (it mangled the vertical advance height).
+
+    - Fixed byte  endian issues  of `ftmac.c' to  support Mac OS  X on
+      i386.
+
+    - The  PFR  font loader  no  longer  erroneously  tags font  files
+      without any outlines as FT_FACE_FLAG_SCALABLE.
+
+
+  II. NEW API FUNCTIONS
+
+    - `FT_Library_SetLcdFilter' allows you  to select a special filter
+      to be  applied to the bitmaps generated  by `FT_Render_Glyph' if
+      one of the FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V modes has
+      been  selected.  This filter  is used  to reduce  color fringes;
+      several  settings are  available  through the  FT_LCD_FILTER_XXX
+      enumeration.
+
+      Its  declaration   and  documentation  can  be   found  in  file
+      `include/freetype/ftlcdfil.h'   (to  be   accessed   with  macro
+      FT_LCD_FILTER_H).
+
+      *IMPORTANT*:     This      function     returns     an     error
+      (FT_Err_Unimplemented_Feature) in default  builds of the library
+      for patent reasons.  See below.
+
+    - `FT_Get_Gasp'  allows you  to query  the flags  of  the TrueType
+      `gasp' table for  a given character pixel size.   This is useful
+      to duplicate  the text rendering  of MS Windows when  the native
+      bytecode  interpreter is  enabled (which  isn't the  default for
+      other patent reasons).
+
+      Its  declaration   and  documentation  can  be   found  in  file
+      `include/freetype/ftgasp.h'   (to   be   accessed   with   macro
+      FT_GASP_H).
+
+
+  III. IMPORTANT CHANGES
+
+    - The auto-hinter has been tuned a lot to improve its results with
+      serif fonts, resulting in much better font rendering of many web
+      pages.
+
+    - The unpatented  hinter is now part  of the default  build of the
+      library; we  have added  code to automatically  support `tricky'
+      fonts that need it.
+
+      This means  that FreeType should `just work'  with certain Asian
+      fonts, like  MingLiU, which cannot properly be  loaded without a
+      bytecode interpreter,  but which fortunately  do not use  any of
+      the patented  bytecode opcodes.  We detect these  fonts by name,
+      so please  report any font file  that doesn't seem  to work with
+      FreeType, and  we shall do what we  can to support it  in a next
+      release.
+
+      Note  that  the API  hasn't  changed,  so  you can  still  force
+      unpatented hinting with a special parameter to `FT_Open_Face' as
+      well.  This  might be useful in  same cases; for  example, a PDF
+      reader might present  a user option to activate  it to deal with
+      certain  `tricky'   embedded  fonts  which   cannot  be  clearly
+      identified.
+
+      If you are  a developer for embedded systems,  you might want to
+      *disable*  the   feature  to  save  code   space  by  undefining
+      TT_CONFIG_OPTION_UNPATENTED_HINTING in file `ftoption.h'.
+
+    - LCD-optimized rendering is now  *disabled* in all default builds
+      of  the  library,  mainly   due  to  patent  issues.   For  more
+      information see:
+
+      http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html
+
+      A  new  configuration macro  FT_CONFIG_OPTION_SUBPIXEL_RENDERING
+      has been introduced in  `ftoption.h'; manually define it in this
+      file if you want to re-enable the feature.
+
+      The  change only  affects the  implementation, not  the FreeType
+      API.  This means that clients don't need to be modified, because
+      the library still generates  LCD decimated bitmaps, but with the
+      added constraint that R=G=B on each triplet.
+
+      The  displayed result  should  be equal  to normal  anti-aliased
+      rendering.
+
+      Additionally,  if   FT_CONFIG_OPTION_SUBPIXEL_RENDERING  is  not
+      defined, the new  `FT_Library_SetLcdFilter' function returns the
+      FT_Err_Unimplemented_Feature error code.
+
+    - Some computation bugs in  the TrueType bytecode interpreter were
+      found,  which  allow us  to  get rid  of  very  subtle and  rare
+      differences we had experienced with the Windows renderer.
+
+    - It is now possible to cross-compile the library easily.  See the
+      file `docs/INSTALL.CROSS' for details.
+
+    - The file `src/base/ftmac.c' now contains code for Mac OS X only;
+      its  deprecated function  `FT_GetFile_From_Mac_Font_Name' always
+      returns an  error even if the QuickDraw  framework is available.
+      The previous version has been moved to `builds/mac/ftmac.c'.
+
+      Selecting  configure option `--with-quickdraw-carbon'  makes the
+      build process use the original `ftmac.c' file instead of the Mac
+      OS X-only version.
+
+
+  IV. MISCELLANEOUS
+
+    - Various performance and memory footprint optimizations have been
+      performed on  the TrueType and CFF font  loaders, sometimes with
+      very drastic  benefits (e.g., the  TrueType loader is  now about
+      25% faster;  FreeType should use  less heap memory  under nearly
+      all conditions).
+
+    - The anti-aliased rasterizer has been optimized and is now 15% to
+      25%  percent  faster than  in  previous  versions, depending  on
+      content.
+
+    - The Type 1 loader has been improved; as an example, it now skips
+      top-level dictionaries properly.
+
+    - Better support for Mac  fonts on POSIX systems, plus compilation
+      fixes for Mac OS X on ppc64 where `ftmac.c' cannot be built.
+
+    - Configuration  without `--with-old-mac-fonts'  does  not include
+      `ftmac.c' (this was the behaviour in FreeType version 2.1.10).
+
+    - The TrueTypeGX validator (gxvalid) checks the order of glyph IDs
+      in the kern table.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.2.1 and 2.2
+
+  I. IMPORTANT BUG FIXES
+
+    - Various integer overflows have been fixed.
+
+    - PFB fonts with MacOS resource fork weren't  handled correctly on
+      non-MacOS platforms.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.2 and 2.1.10
+
+(not released officially)
+
+  I. IMPORTANT BUG FIXES
+
+    - Vertical metrics for SFNT fonts were incorrect sometimes.
+
+    - The FT_HAS_KERNING macro always returned 0.
+
+    - CFF OpenType  fonts didn't  return correct vertical  metrics for
+      glyphs with outlines.
+
+    - If FreeType was compiled without hinters, all font formats based
+      on PS outlines weren't scaled correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - Version 2.2 no longer exposes its internals, this is, the header
+      files  located in  the `include/freetype/internal'  directory of
+      the source package are not  copied anymore by the `make install'
+      command.  Consequently, a number of rogue clients which directly
+      access  FreeType's  internal   functions  and  structures  won't
+      compile without modification.
+
+      We provide  patches for  most of those  rogue clients.   See the
+      following page for more information:
+
+        http://www.freetype.org/freetype2/patches/rogue-patches.html
+
+      Note that, as  a convenience to our Unix  desktop users, version
+      2.2 is *binary* compatible with FreeType 2.1.7, which means that
+      installing this  release on  an existing distribution  shall not
+      break any working desktop.
+
+    - FreeType's build  mechanism has been redesigned.   With GNU make
+      it  is  now  sufficient  in   most  cases  to  edit  two  files:
+      `modules.cfg',  to  select   the  library  components,  and  the
+      configuration  file  `include/freetype/config/ftoption.h' (which
+      can be copied to the objects directory).  Removing unused module
+      directories   to    prevent   its   compilation    and   editing
+      `include/freetype/config/ftmodule.h' is no longer necessary.
+
+    - The  LIGHT  hinting algorithm  produces  more pleasant  results.
+      Also, using the  FT_LOAD_TARGET_LIGHT flags within FT_Load_Glyph
+      always forces auto-hinting, as a special exception.  This allows
+      you to experiment with it  even if you have enabled the TrueType
+      bytecode interpreter in your build.
+
+    - The auto hinter now employs a new algorithm for CJK fonts, based
+      on Akito  Hirai's patch.   Note that this  only works  for fonts
+      with a Unicode charmap at the moment.
+
+    - The following callback function  types have changed slightly (by
+      adding the `const' keyword where appropriate):
+
+        FT_Outline_MoveToFunc
+        FT_Outline_LineToFunc
+        FT_Outline_ConicToFunc
+        FT_Outline_CubicToFunc
+        FT_SpanFunc
+        FT_Raster_RenderFunc
+
+        FT_Glyph_TransformFunc
+        FT_Renderer_RenderFunc
+        FT_Renderer_TransformFunc
+
+      Note that this doesn't affect binary backward compatibility.
+
+    - On MacOS,  new APIs have  been added as replacements  for legacy
+      APIs:  `FT_New_Face_From_FSRef'  for  `FT_New_Face_From_FSSpec',
+      and              `FT_GetFile_From_Mac_ATS_Name'              for
+      `FT_GetFile_From_Mac_Name'.  Legacy APIs are still available, if
+      FreeType is built without disabling them.
+
+    - A new  API `FT_Select_Size'  has been added  to select  a bitmap
+      strike  by its  index.   Code using  other  functions to  select
+      bitmap strikes should be updated to use this function.
+
+    - A  new API  `FT_Get_SubGlyph_Info'  has been  added to  retrieve
+      subglyph data.  This can be  used by rogue clients which used to
+      access the internal headers to get the corresponding data.
+
+    - In 2.1.10, the behaviour of `FT_Set_Pixel_Sizes' was changed for
+      BDF/PCF fonts,  and only  for them.  This  causes inconsistency.
+      In this release,  we undo the change.  The  intent of the change
+      in 2.1.10  is to allow  size selection through  real dimensions,
+      which can now be done through `FT_Request_Size'.
+
+    - Some security  issues were discovered  and fixed in the  CFF and
+      Type  1 loader, causing  crashes of  FreeType by  malformed font
+      files.
+
+
+  III. MISCELLANEOUS
+
+    - The documentation  for FT_LOAD_TARGET_XXX and FT_RENDER_MODE_XXX
+      values now better reflects its usage and differences: One set is
+      used to specify the hinting algorithm, the other to specify  the
+      pixel rendering mode.
+
+    - `FT_New_Face' and `FT_New_Face_From_FSSpec' in ftmac.c have been
+      changed to count supported scalable faces (sfnt, LWFN) only, and
+      to  return the  number of  available faces  via face->num_faces.
+      Unsupported bitmap faces (fbit, NFNT) are ignored.
+
+    - builds/unix/configure  has been  improved for  MacOS X.   It now
+      automatically checks available  functions in Carbon library, and
+      prepare to use newest  functions by default.  Options to specify
+      the  dependencies of  each Carbon  APIs (FSSpec,  FSRef, old/new
+      QuickDraw, ATS)  are available too.  By manual  disabling of all
+      QuickDraw   functionality,  FreeType   can   be  built   without
+      `deprecated   function'   warnings    on   MacOS   10.4.x,   but
+      FT_GetFile_Mac_Name  in  ftmac.c  then  is changed  to  a  dummy
+      function, and returns an `unimplemented' error.  For details see
+      builds/mac/README.
+
+    - SFNT cmap handling has been  improved, mainly to run much faster
+      with CJK fonts.
+
+    - A   new  function   `FT_Get_TrueType_Engine_Type   (declared  in
+      `FT_MODULE_H')  is  provided  to  determine the  status  of  the
+      TrueType   bytecode  interpreter   compiled  into   the  library
+      (patented, unpatented, unimplemented).
+
+    - Vertical metrics of glyphs are  synthesized if the font does not
+      provide such information.  You can tell whether  the metrics are
+      synthesized or not by checking the FT_FACE_FLAG_VERTICAL flag of
+      the face.
+
+    - The demo programs  `ftview' and  `ftstring' have been  rewritten
+      for better readability.   `ftview' has a new switch `-p' to test
+      FT_New_Memory_Face (instead of FT_New_Face).
+
+    - FreeType now honours bit 1 in the `head' table of TrueType fonts
+      (meaning `left sidebearing point at x=0').  This helps with some
+      buggy fonts.
+
+    - Rudimentary support for Adobe's new `SING Glyphlet' format.  See
+
+        http://www.adobe.com/products/indesign/sing_gaiji.html
+
+      for more information.
+
+    - The `ftdump'  program from the `ft2demos' bundle  now shows some
+      information about charmaps.  It  also supports a new switch `-v'
+      to increase verbosity.
+
+    - Better AFM support.  This includes track kerning support.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.10 and 2.1.9
+
+  I. IMPORTANT BUG FIXES
+
+    - The size comparison for BDF and PCF files could fail sometimes.
+
+    - Some  CFF files  were still not  loaded  correctly.   Patch from
+      Derek Noonburg.
+
+    - The stroker still had some serious bugs.
+
+    - Boris  Letocha  fixed a  bug in  the  TrueType interpreter:  The
+      NPUSHW instruction wasn't skipped correctly in IF clauses.  Some
+      fonts like `Helvetica 75 Bold' failed.
+
+    - Another  serious  bug  in  handling  TrueType hints  caused many
+      distortions.  It has been introduced in version 2.1.8, and it is
+      highly recommended to upgrade.
+
+    - FreeType didn't properly parse empty Type 1 glyphs.
+
+    - An unbound dynamic buffer growth was fixed in the PFR loader.
+
+    - Several bugs have been fixed in the cache sub-system.
+
+    - FreeType behaved incorrectly when resizing two distinct but very
+      close character pixel sizes through `FT_Set_Char_Size' (Savannah
+      bug #12263).
+
+    - The auto-hinter didn't work properly for fonts without a Unicode
+      charmap -- it even refused to load the glyphs.
+
+
+  II. IMPORTANT CHANGES
+
+    - Many fixes have been applied to drastically reduce the amount of
+      heap   memory   used   by   FreeType,   especially   when  using
+      memory-mapped font files  (which is the default on Unix  systems
+      which support them).
+
+    - The auto-hinter  has been replaced with a new module, called the
+      `auto-fitter'.  It consumes  less memory  than its  predecessor,
+      and it is  prepared to support non-latin scripts  better in next
+      releases.
+
+    - George Williams  contributed code to read  kerning data from PFM
+      files.
+
+    - FreeType   now   uses    the   TT_NAME_ID_PREFERRED_FAMILY   and
+      TT_NAME_ID_PREFERRED_SUBFAMILY   strings   (if   available)  for
+      setting  family  and  style in SFNT  fonts  (patch from Kornfeld
+      Eliyahu Peter).
+
+    - A  new  API `FT_Sfnt_Table_Info'  (in FT_TRUETYPE_TABLES_H)  has
+      been added to retrieve name and size information of SFNT tables.
+
+    - A new API `FT_OpenType_Validate' (in FT_OPENTYPE_VALIDATE_H) has
+      been added to validate OpenType tables  (BASE, GDEF, GPOS, GSUB,
+      JSTF).   After validation  it is  no longer  necessary to  check
+      for errors in those tables while accessing them.
+
+      Note that  this module might  be moved to another library in the
+      future  to avoid  a tight  dependency between  FreeType and  the
+      OpenType specification.
+
+    - A new API in FT_BITMAP_H  (`FT_Bitmap_New', `FT_Bitmap_Convert',
+      `FT_Bitmap_Copy',  `FT_Bitmap_Embolden',  `FT_Bitmap_Done')  has
+      been added.   Its  use is  to convert an  FT_Bitmap structure in
+      1bpp, 2bpp,  4bpp, or 8bpp  format into  another 8bpp FT_Bitmap,
+      probably using a different pitch, and to further manipulate it.
+
+    - A new  API `FT_Outline_Embolden'  (in FT_OUTLINE_H) gives  finer
+      control how  outlines are embolded.
+
+    - `FT_GlyphSlot_Embolden' (in FT_SYNTHESIS_H)  now handles bitmaps
+      also (code contributed  by Chia I Wu).  Note that this  function
+      is still experimental and may be replaced with a better API.
+
+    - The method  how BDF and PCF  bitmap fonts  are accessed has been
+      refined.   Formerly,   FT_Set_Pixel_Sizes  and  FT_Set_Char_Size
+      were  synonyms in  FreeType's  BDF and PCF interface.  This  has
+      changed now.  FT_Set_Pixel_Sizes  should be  used to  select the
+      actual  font dimensions  (the `strike',  which is the sum of the
+      `FONT_ASCENT'    and    `FONT_DESCENT'    properties),     while
+      FT_Set_Char_Size  selects  the  `nominal' size  (the `PIXELSIZE'
+      property).  In both functions, the width parameter is ignored.
+
+
+  III. MISCELLANEOUS
+
+    - The BDF driver  no longer converts  all returned bitmaps  with a
+      depth of 2bpp or 4bpp to a depth of 8bpp.  The documentation has
+      not  mentioned  this  explicitly,  but  implementors  might have
+      relied on this after looking into the source files.
+
+    - A new option `--ftversion' has been  added to freetype-config to
+      return the FreeType version.
+
+    - The  memory  debugger  has  been  updated   to  dump  allocation
+      statistics on  all allocation  sources in the library.   This is
+      useful to  spot greedy  allocations when  loading and processing
+      fonts.
+
+    - We removed a huge array of constant pointers to constant strings
+      in the `psnames' module.   The problem was that  compilations in
+      PIC mode (i.e.,  when generating a  Unix shared object/dll)  put
+      the array  into the non-shared  writable section of  the library
+      since absolute pointers are not relocatable by nature.
+
+      This reduces the memory consumption by approximately 16KByte per
+      process linked  to FreeType.   We now also store  the array in a
+      compressed form (as a trie) which saves about 20KByte of code as
+      well.
+
+    - Kirill  Smelkov provided  patches to make  src/raster/ftraster.c
+      compile stand-alone again.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.9 and 2.1.8
+
+  I. IMPORTANT BUG FIXES
+
+    - The function  `FT_Get_CharMap_Index' was only declared,  without
+      any  real  code.   For  consistency,  it  has  been  renamed  to
+      `FT_Get_Charmap_Index'.   (This function is needed  to implement
+      cmap caches.)
+
+    - `FT_Outline_Get_BBox'  sometimes returned  incorrect values  for
+      conic outlines (e.g., for TrueType fonts).
+
+    - Handling of `bhed' table has been fixed.
+
+    - The TrueType driver with enabled byte code interpreter sometimes
+      returned artifacts due to incorrect rounding.  This bug has been
+      introduced after version 2.1.4.
+
+    - The BDF driver dropped the last glyph in the font.
+
+    - The BDF driver now uses the DEFAULT_CHAR property (if available)
+      to select a glyph shape for the undefined glyph.
+
+    - The stroker failed for closed outlines and single points.
+
+
+  II. IMPORTANT CHANGES
+
+    - George  Williams   contributed  code  to   handle  Apple's  font
+      distortion technology found in GX fonts (`avar', `cvar', `fvar',
+      and `gvar' tables;  the Multiple Masters  API has been  slightly
+      extended to cope with the new functionality).
+
+    - The `FT_GlyphSlotRec' structure has been extended:  The elements
+      `lsb_delta' and  `rsb_delta' give the difference  between hinted
+      and  unhinted  left and right  side bearings  if autohinting  is
+      active.  Using those values can improve the inter-letter spacing
+      considerably.   See the documentation of  `FT_GlyphSlotRec'  and
+      the `ftstring' demo program how to use it.
+
+    - Loading TrueType and Type 1 fonts has been made much faster.
+
+    - The stroker is  no longer experimental (but the  cache subsystem
+      still is).
+
+
+  III. MISCELLANEOUS
+
+    - A new  documentation file  `formats.txt' describes various  font
+      formats supported (and not supported) by FreeType.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.8 and 2.1.7
+
+  I. IMPORTANT BUG FIXES
+
+    - The native  TrueType hinter contained some  bugs which prevented
+      some fonts to be rendered correctly, most notably Legendum.otf.
+
+    - The PostScript hinter now produces improved results.
+
+    - The  linear advance  width  and height  values were  incorrectly
+      rounded,  making  them virtually  unusable  if  not loaded  with
+      FT_LOAD_LINEAR_DESIGN.
+
+    - Indexing CID-keyed CFF fonts is  now working: The glyph index is
+      correctly  treated as a  CID, similar  to FreeType's  CID driver
+      module.  Note that CID CMap support is still missing.
+
+    - The FT_FACE_FLAGS_GLYPH_NAMES flag is now  set correctly for all
+      font formats.
+
+    - Some subsetted Type 1  fonts weren't parsed correctly.  This bug
+      has been introduced in 2.1.7.  In summary, the Type 1 parser has
+      become more robust.
+
+    - Non-decimal numbers weren't parsed correctly in PS fonts.
+
+    - The WinFNT driver now correctly reports FT_ENCODING_NONE for all
+      but one encoding.  Use  the new FT_WinFNT_ID_XXX values together
+      with `FT_Get_WinFNT_Header' to get the WinFNT charset ID.
+
+    - The descender metrics (face->size->metrics.descender) for WinFNT
+      bitmap fonts had the wrong sign.
+
+    - The (emulated) `seac' support for CFF fonts was broken.
+
+    - The `flex' operator didn't work for CFF fonts.
+
+    - PS glyphs  which  use  the   `hintmask'  operator  haven't  been
+      rendered correctly in some cases.
+
+    - Metrics for BDF and PCF bitmap font formats have been fixed.
+
+    - Autohinting  is now  disabled for  glyphs  which  are vertically
+      distorted  or mirrored  (using a  transformation matrix).   This
+      fixes a bug which produced zero-height glyphs.
+
+    - The   `freetype-config'   script   now  handles   --prefix   and
+      --exec-prefix correctly; it also  returns the proper --rpath (or
+      -R) value if FreeType has been built as a shared library.
+
+
+  II. IMPORTANT CHANGES
+
+    - Both  PCF  and BDF  drivers  now  handle  the SETWIDTH_NAME  and
+      ADD_STYLE_NAME    properties.     Values    are   appended    to
+      face->style_name; example: `Bold SemiCondensed'.
+
+    - The PCF driver now handles bitmap  fonts compressed with the LZW
+      algorithm (extension .pcf.Z, compressed with `compress').
+
+    - A  new  API   function  `FT_Get_CMap_Language_ID'  (declared  in
+      `tttables.h')  is  available  to   get  the  language  ID  of  a
+      TrueType/SFNT cmap.
+
+    - The hexadecimal format of  data after the `StartData' command in
+      CID-keyed Type 1 fonts is now supported.  While this can't occur
+      in  file-based   fonts,  it  can   happen  in  document-embedded
+      resources of PostScript documents.
+
+    - Embedded bitmaps in SFNT-based CFF fonts are now supported.
+
+    - A simple  API is  now available  to control  FreeType's  tracing
+      mechanism if compiled  with FT_DEBUG_LEVEL_TRACE.   See the file
+      `ftdebug.h' for more details.
+
+    - YAMATO Masatake contributed improved  handling of MacOS resource
+      forks on non-MacOS platforms (for example, Linux can mount MacOS
+      file systems).
+
+    - Support for MacOS has been improved; there is now a new function
+      `FT_New_Face_From_FSSpec'  similar to `FT_New_Face'  except that
+      it accepts an FSSpec instead of a path.
+
+    - The cache sub-system has been rewritten.
+
+      - There is now support for deinstallation of faces.
+
+      - A new  API function `FTC_Manager_RemoveFaceID'  has been added
+        to  delete  all  `idle'  nodes  that  correspond  to  a  given
+        FTC_FaceID.  All `locked' nodes  (i.e., those with a reference
+        count > 0), will be modified to prevent them from appearing in
+        further  lookups (they  will  be cleaned  normally when  their
+        reference count reaches 0).
+
+      - There  is  now  support  for point  scaling  (i.e.,  providing
+        character sizes in points + dpis, instead of pixels).
+
+      - Three abstract cache classes are now available:
+
+          FTC_GCache:  Used to store  one glyph  item per  cache node,
+                      with the ability to group common attributes into
+                      `families'.      This    replaces     the    old
+                      FTC_GlyphCache class.
+
+          FTC_ICache: Used to store one FT_Glyph per cache node.  This
+                      extends  FTC_GCache.  Family  definition, family
+                      comparison, and  glyph loading are  however left
+                      to sub-classes.
+
+          FTC_SCache: Used to  store up to 16 small  bitmaps per cache
+                      node.    This    extends   FTC_GCache.    Family
+                      definition, family  comparison and glyph loading
+                      are however left to sub-classes.
+
+      - The file `src/cache/ftcbasic.c' implements:
+
+          FTC_ImageCache: Extends    FTC_ICache;   implements   family
+                          definitions and glyph loading similar to the
+                          old API.
+
+          FTC_SBitCache: Extends    FTC_SCache,    implements   family
+                         definitions and glyph  loading similar to the
+                         old API
+
+        Client  applications  should  be  able to  extend  FTC_GCache,
+        FTC_ICache, or FTC_SCache much more easily (i.e., less code to
+        write, and  less callbacks).  For example,  one could envision
+        caches  that are  capable of  storing  transformed (obliqued),
+        stroked,   emboldened,   or   colored   glyph   images.    Use
+        `ftcbasic.c' as an example.
+
+      - All public  APIs are now  in `include/freetype/ftcache.h', (to
+        be    accessed   as    `FT_CACHE_H').     The   contents    of
+        `include/freetype/cache/' is only  needed by applications that
+        wish to implement their own caches.
+
+      - There were some major performance improvements through the use
+        of  various programming  tricks.   Cache hits  are  up to  70%
+        faster than in the old code.
+
+      - The  FTC_CMapCache has  been simplified.  Charmaps can only be
+        accessed by  index right now.  There  is also a  new API named
+        `FT_Charmap_GetIndex' for this purpose.
+
+      - The  demo programs  have been  updated to  the new  code.  The
+        previous versions will not work with the current one.
+
+      - Using  an invalid face  index in FT_Open_Face and friends  now
+        causes an error even if the font contains a single face only.
+
+
+  III. MISCELLANEOUS
+
+    - Wolfgang Domröse contributed support files for building FreeType
+      on the Atari using the PureC compiler.  Note that the Atari is a
+      16bit platform.
+
+    - Vitaliy Pasternak contributed project files for VS.NET 2003.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.7 and 2.1.6
+
+  I. IMPORTANT BUG FIXES
+
+    - Updated  to newest  libtool  version, fixing  build problems  on
+      various platforms.
+
+    - On  Unix  platforms,  `make  install' didn't  copy  the  correct
+      `ftconfig.h' file.
+
+  Note that version 2.1.7  contains the same library  C source code as
+  version 2.1.6.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.6 and 2.1.5
+
+  I. IMPORTANT BUG FIXES
+
+    - The PFR  font driver didn't  load kerning tables  correctly, and
+      the functions in FT_PFR_H didn't work at all.
+
+    - Type 1 font  files in  binary format  (PFB) with  an end-of-file
+      indicator weren't accepted by the FreeType engine.
+
+    - Fonts which contain /PaintType  and /StrokeWidth no longer cause
+      a segfault.  This bug has been introduced in version 2.1.5.
+
+    - Fonts  loaded  with   FT_LOAD_RENDER  no  longer  cause  strange
+      results.  This bug has been introduced in version 2.1.5.
+
+    - Some  Windows   (bitmap)  FNT/FON  files   couldn't  be  handled
+      correctly.
+
+
+  II. IMPORTANT CHANGES
+
+    - The internal  module API  has been heavily  changed in  favor of
+      massive simplifications within the font engine.  This also means
+      that authors of third-party modules must adapt their code to the
+      new scheme.
+
+      NOTE:  THE NEW SCHEME IS NOT COMPLETED YET.  PLEASE WAIT UNTIL A
+      FINAL ANNOUNCEMENT!
+
+    - The PostScript  parser has been enhanced to  handle comments and
+      strings   correctly.   Additionally,   more  syntax   forms  are
+      recognized.
+
+    - Added the  optional unpatented hinting system  for TrueType.  It
+      allows  typefaces which  need hinting  to produce  correct glyph
+      forms (e.g., Chinese typefaces  from Dynalab) to work acceptably
+      without infringing Apple patents.   This system is compiled only
+      if  TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING  is  defined  in
+      ftoption.h (activated by default).
+
+
+  III. MISCELLANEOUS
+
+    - There  is now  a guard  in the  public header  files  to protect
+      against inclusion of freetype.h from FreeType 1.
+
+    - Direct inclusion of freetype.h  and other public header files no
+      longer works.  You have to use the documented scheme
+
+        #include <ft2build.h>
+        #include FT_FREETYPE_H
+
+      to load freetype.h with  a symbolic name.  This protects against
+      renaming  of public  header  files (which  shouldn't happen  but
+      actually  has, avoiding two  public header  files with  the same
+      name).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.5 and 2.1.4
+
+  I. IMPORTANT BUG FIXES
+
+    - Parsing the /CIDFontName field  now removes the leading slash to
+      be in sync with other font drivers.
+
+    - gzip support was buggy.  Some fonts could not be read.
+
+    - Fonts which  have nested subglyphs  more than one level  deep no
+      longer cause a segfault.
+
+    - Creation of synthetic  cmaps for fonts in CFF  format was broken
+      partially.
+
+    - Numeric  font  dictionary entries  for  synthetic  fonts are  no
+      longer overwritten.
+
+    - The font matrix  wasn't applied to the advance  width for Type1,
+      CID, and  CFF fonts.  This caused problems  when loading certain
+      synthetic Type 1 fonts like `Helvetica Narrow'.
+
+    - The test  for the charset registry  in BDF and PCF  fonts is now
+      case-insensitive.
+
+    - FT_Vector_Rotate  sometimes  returned   strange  values  due  to
+      rounding errors.
+
+    - The  PCF  driver  now  returns  the  correct  number  of  glyphs
+      (including an artificial `notdef' glyph at index 0).
+
+    - FreeType now  supports buggy CMaps  which are contained  in many
+      CJK fonts from Dynalab.
+
+    - Opening  an invalid  font  on a  Mac  caused a  segfault due  to
+      double-freeing memory.
+
+    - BDF  fonts  with  more   than  32768  glyphs  weren't  supported
+      properly.
+
+
+  II. IMPORTANT CHANGES
+
+    - Accessing bitmap font formats has been synchronized.  To do that
+      the FT_Bitmap_Size  structure has  been extended to  contain new
+      fields `size', `x_ppem', and `y_ppem'.
+
+    - The FNT driver now returns multiple faces, not multiple strikes.
+
+    - The `psnames'  module has been  updated to the Adobe  Glyph List
+      version 2.0.
+
+    - The `psnames' module now understands `uXXXX[X[X]]' glyph names.
+
+    - The algorithm for guessing the font style has been improved.
+
+    - For fonts in SFNT format, root->height is no longer increased if
+      the line gap  is zero.  There exist fonts  (containing e.g. form
+      drawing  characters) which  intentionally have  a zero  line gap
+      value.
+
+    - ft_glyph_bbox_xxx  flags   are  now  deprecated   in  favour  of
+      FT_GLYPH_BBOX_XXX.
+
+    - ft_module_xxx   flags   are   now   deprecated  in   favour   of
+      FT_MODULE_XXX.
+
+    - FT_ENCODING_MS_{SJIS,GB2312,BIG5,WANSUNG,JOHAB}      are     now
+      deprecated               in               favour              of
+      FT_ENCODING_{SJIS,GB2312,GIB5,WANSONG,JOHAB}  -- those encodings
+      are not specific to Microsoft.
+
+
+  III. MISCELLANEOUS
+
+    - The  autohinter  has been  further  improved;  for example,  `m'
+      glyphs now retain its vertical symmetry.
+
+    - Partial support of Mac fonts on non-Mac platforms.
+
+    - `make   refdoc'   (after   first   `make')   builds   the   HTML
+      documentation.  You need Python for this.
+
+    - The make build system should  now work more reliably on DOS-like
+      platforms.
+
+    - Support for  EMX gcc  and Watson C/C++  compilers on  MS-DOS has
+      been added.
+
+    - Better VMS build support.
+
+    - Support for the pkg-config  package by providing a `freetype.pc'
+      file.
+
+    - New configure option --with-old-mac-fonts for Darwin.
+
+    - Some source files have been  renamed (mainly to fit into the 8.3
+      naming scheme).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.4 and 2.1.3
+
+  I. IMPORTANT BUG FIXES
+
+    - Updated  to newest  libtool  version, fixing  build problems  on
+      various platforms.
+
+    - A fix  in the Gzip stream  reader: It couldn't  read certain .gz
+      files properly due to a  small typo.  In certain cases, FreeType
+      could  also loop  endlessly  when trying  to  load tiny  gzipped
+      files.
+
+    - The configure script now tries  to use the system-wide zlib when
+      it  finds one  (instead of  the  copy found  in src/gzip).   And
+      `freetype-config' has  been updated to return  relevant flags in
+      this case when invoked with `--libs' (e.g. `-lzlib').
+
+    - Certain fonts couldn't be loaded  by 2.1.3 because they lacked a
+      Unicode   charmap  (e.g.   SYMBOL.TTF).    FreeType  erroneously
+      rejected them.
+
+    - The CFF loader was modified to accept fonts which only contain a
+      subset of  their reference charset.  This  prevented the correct
+      use of PDF-embedded fonts.
+
+    - The logic to detect Unicode charmaps has been modified.  This is
+      required to  support fonts which include both  16-bit and 32-bit
+      charmaps (like very  recent asian ones) using the  new 10 and 12
+      SFNT formats.
+
+    - The TrueType  loader now limits  the depth of  composite glyphs.
+      This is necessary to prevent broken fonts to break the engine by
+      blowing the stack with recursive glyph definitions.
+
+    - The CMap cache is now  capable of managing UCS-4 character codes
+      that   are   mapped   through   extended  charmaps   in   recent
+      TrueType/OpenType fonts.
+
+    - The   cache  sub-system   now  properly   manages  out-of-memory
+      conditions  instead of  blindly  reporting them  to the  caller.
+      This means that it will try to empty the cache before restarting
+      its allocations to see if that can help.
+
+    - The  PFR driver  didn't return  the list  of  available embedded
+      bitmaps properly.
+
+    - There was  a nasty  memory leak when  using embedded  bitmaps in
+      certain font formats.
+
+
+  II. IMPORTANT CHANGES
+
+    - David Chester  contributed some enhancements  to the auto-hinter
+      that  significantly increase  the  quality of  its output.   The
+      Postscript hinter was also improved in several ways.
+
+    - The FT_RENDER_MODE_LIGHT render mode was implemented.
+
+    - A new  API function called `FT_Get_BDF_Property'  has been added
+      to FT_BDF_H to  retrieve BDF properties from BDF  _and_ PCF font
+      files.   THIS  IS  STILL  EXPERIMENTAL,  since  it  hasn't  been
+      properly tested yet.
+
+    - A Windows FNT specific API has been added, mostly to access font
+      headers.  This is used by Wine.
+
+    - TrueType tables  without an `hmtx' table are  now tolerated when
+      an  incremental interface  is  used.  This  happens for  certain
+      Type42 fonts passed from Ghostscript to FreeType.
+
+    - The PFR font driver is  now capable of returning the font family
+      and style  names when  they are available  (instead of  the sole
+      `FontID').   This  is  performed  by parsing  an  *undocumented*
+      portion of the font file!
+
+
+  III. MISCELLANEOUS
+
+    - The path stroker in FT_STROKER_H has entered beta stage.  It now
+      works very  well, but  its interface might  change a bit  in the
+      future.  More on this in later releases.
+
+    - The documentation for  FT_Size_Metrics didn't appear properly in
+      the API reference.
+
+    - The file docs/VERSION.DLL has been updated to explain versioning
+      with FreeType  (i.e., comparing release/libtool/so  numbers, and
+      how to use them in autoconf scripts).
+
+    - The  installation  documentation  has been  seriously  revamped.
+      Everything is now in the `docs' directory.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.3 and 2.1.2
+
+  I. IMPORTANT BUG FIXES
+
+    - FT_Vector_Transform  had  been  incorrectly modified  in  2.1.2,
+      resulting  in  incorrect   transformations  being  applied  (for
+      example, rotations were processed in opposite angles).
+
+    - The format  8 and 12 TrueType charmap  enumeration routines have
+      been fixed (FT_Get_Next_Char returned invalid values).
+
+    - The  PFR font driver  returned incorrect  advance widths  if the
+      outline  and metrics resolution  defined in  the font  file were
+      different.
+
+    - FT_Glyph_To_Bitmap now returns  successfully when called with an
+      FT_BitmapGlyph argument (it previously returned an error).
+
+    - A bug  in the Type 1  loader that prevented  valid font bounding
+      boxes to be loaded from multiple master fonts.
+
+    - The SFNT  validation code has been rewritten.   FreeType can now
+      load `broken'  fonts that were  usable on Windows, but  not with
+      previous versions of the library.
+
+    - The computation of bearings in the BDF driver has been fixed.
+
+    - The Postscript hinter crashed when trying to hint certain glyphs
+      (more precisely,  when trying to  apply hints to an  empty glyph
+      outline).
+
+    - The  TrueType glyph  loader  now supports  composites in  `Apple
+      format'  (they differ slightly  from Microsoft/OpenType  ones in
+      the way transformation offsets are computed).
+
+    - FreeType was  very slow at opening certain  asian CID/CFF fonts,
+      due to  fixed increment  in dynamic array  re-allocations.  This
+      has  been changed  to  exponential behaviour  to get  acceptable
+      performance.
+
+
+
+  II. IMPORTANT CHANGES
+
+    - The PCF driver now supports gzip-compressed font files natively.
+      This means that  you will be able to use  all these bitmap fonts
+      that  come with  XFree86 with  FreeType (and  libXft/libXft2, by
+      extension).
+
+    - The  automatic and  postscript hinters  have both  been updated.
+      This  results in  a relatively  important increase  of rendering
+      quality since  many nasty defaults have been suppressed.  Please
+      visit the web page:
+
+        http://www.freetype.org/hinting/smooth-hinting.html
+
+      for additional details on this topic.
+
+    - The `load_flags' parameter of `FT_Load_Glyph' is now an FT_Int32
+      (instead  of just  being  an FT_Int).   This  breaks source  and
+      binary  compatibility for  16bit systems  only,  while retaining
+      both of them for 32 and 64 bit ones.
+
+      Some new flags have been added consequently:
+
+        FT_LOAD_NO_AUTOHINT   :: Disable the use of the auto-hinter
+                                 (but not native format hinters).
+
+        FT_LOAD_TARGET_NORMAL :: Hint and render for normal
+                                 anti-aliased displays.
+
+        FT_LOAD_TARGET_MONO   :: Hint and render for 1-bit displays.
+
+        FT_LOAD_TARGET_LCD    :: Hint and render for horizontal RGB or
+                                 BGR sub-pixel displays (like LCD
+                                 screens).  THIS IS STILL
+                                 EXPERIMENTAL!
+
+        FT_LOAD_TARGET_LCD_V  :: Same as FT_LOAD_TARGET_LCD, for
+                                 vertical sub-pixel displays (like
+                                 rotated LCD screens).  THIS IS STILL
+                                 EXPERIMENTAL!
+
+      FT_LOAD_MONOCHROME   is  still   supported,  but   only  affects
+      rendering, not the hinting.
+
+      Note that the `ftview'  demo program available in the `ft2demos'
+      package  has been  updated to  support LCD-optimized  display on
+      non-paletted displays (under Win32 and X11).
+
+    - The  PFR  driver  now  supports embedded  bitmaps  (all  formats
+      supported), and returns correct kerning metrics for all glyphs.
+
+    - The TrueType charmap loader  now supports certain `broken' fonts
+      that load under Windows without problems.
+
+    - The cache API has been slightly modified (it's still a beta!):
+
+       - The type  FTC_ImageDesc has been removed; it  is now replaced
+         by  FTC_ImageTypeRec.   Note that  one  of  its  fields is  a
+         `load_flag' parameter for FT_Load_Glyph.
+
+       - The  field  `num_grays' of  FT_SBitRec  has  been changed  to
+         `max_grays'  in  order to  fit  within  a  single byte.   Its
+         maximum value is thus 255 (instead of 256 as previously).
+
+
+  III. MISCELLANEOUS
+
+    - Added support  for the  DESTDIR variable during  `make install'.
+      This simplifies packaging of FreeType.
+
+    - Included modified  copies of the  ZLib sources in  `src/gzip' in
+      order to support  gzip-compressed PCF fonts.  We do  not use the
+      system-provided  zlib  for  now,   though  this  is  a  probable
+      enhancement for future releases.
+
+    - The DocMaker tool used to generate the on-line API reference has
+      been   completely    rewritten.    It   is    now   located   in
+      `src/tools/docmaker/docmaker.py'.  Features:
+
+        - better cross-referenced output
+        - more polished output
+        - uses Python regular expressions  (though it didn't speed the
+          program)
+        - much  more  modular structure,  which  allows for  different
+          `backends'  in  order to  generate  HTML,  XML, or  whatever
+          format.
+
+      One can regenerate the API reference by calling:
+
+         python src/tools/docmaker/docmaker.py \
+                --prefix=ft2 \
+                --title=FreeType-2.1.3 \
+                --output=<outputdirectory>
+                include/freetype/*.h \
+                include/freetype/config/*.h \
+                include/freetype/cache/*.h
+
+    - A new, experimental, support for incremental font loading (i.e.,
+      loading  of fonts  where the  glyphs are  not in  the  font file
+      itself, but provided by an external component, like a Postscript
+      interpreter) has been added by Graham Asher.  This is still work
+      in progress, however.
+
+    - A new,  EXPERIMENTAL, path stroker  has been added.   It doesn't
+      suffer  from  severe  rounding  errors  and  treat  bezier  arcs
+      directly.  Still work in progress (i.e. not part of the official
+      API).   See  the file  <freetype/ftstroker.h>  for  some of  the
+      details.
+
+    - The massive  re-formatting of sources and  internal re-design is
+      still under-way.  Many  internal functions, constants, and types
+      have been renamed.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.2 and 2.1.1
+
+  I. IMPORTANT BUG FIXES
+
+    - Many  font drivers didn't  select a  Unicode charmap  by default
+      when a new face  was opened (with the FT_CONFIG_OPTION_USE_CMAPS
+      options enabled),  causing many applications  to not be  able to
+      display text correctly with the 2.1.x releases.
+
+    - The  PFR driver had  a bug  in its  composite loading  code that
+      produces incorrectly placed accents with many fonts.
+
+    - The Type42 driver crashed sometimes due to a nasty bug.
+
+    - The Type 1 custom encoding  charmap didn't handle the case where
+      the first glyph index wasn't 0.
+
+    - A  serious  typo  in  the  TrueType  composite  loader  produced
+      incorrectly placed  glyphs in fonts  like `Wingdings' and  a few
+      others.
+
+
+  II. MISCELLANEOUS
+
+    - The Win32  Visual C++ project  file has been updated  to include
+      the PFR driver as well.
+
+    - `freetype.m4' is  now installed by default by  `make install' on
+      Unix systems.
+
+    - The function  FT_Get_PS_Font_Info now works with  CID and Type42
+      fonts as well.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.1 and 2.1.0
+
+  I. IMPORTANT BUG FIXES
+
+    - The  `version_info'  returned   by  `freetype-config'  in  2.1.0
+      returned an invalid value.  It now returns 9:1:3 (2.0.9 returned
+      9:0:3).
+
+    - Version 2.1.0  couldn't be linked against  applications on Win32
+      and  Amiga systems  due  to  a new  debug  function that  wasn't
+      properly   propagated  to   the  system-specific   directory  in
+      `builds'.
+
+    - Various MacOS and Mac OS X specific fixes.
+
+    - Fixed  a bug in  the TrueType  charmap validation  routines that
+      made version  2.1.0 too restrictive  -- many popular  fonts have
+      been rejected.
+
+    - There was  still a very small difference  between the monochrome
+      glyph bitmaps produced by FreeType 1.x and FreeType 2.x with the
+      bytecode  interpreter enabled.   This was  caused by  an invalid
+      flag setting in the TrueType glyph loader, making the rasterizer
+      change  its  drop-out   control  mode.   Now  the results should
+      _really_ be completely identical.
+
+    - The TrueType name table loader has been improved to support many
+      popular  though buggy Asian  fonts.  It  now ignores  empty name
+      entries,  invalid  pointer offsets  and  a  few other  incorrect
+      subtleties.  Moreover,  name strings  are now loaded  on demand,
+      which reduces the memory load  of many faces (e.g. the ARIAL.TTF
+      font file contains a 10kByte name table with 70 names).
+
+    - Fixed a bug in the Postscript hinter that prevented family blues
+      substitution to happen correctly.
+
+
+  II. NEW FEATURES
+
+    - Three new font drivers in this release:
+
+      * A  BDF  font driver,  contributed  by  Franco Zappa  Nardelli,
+        heavily  modified   by  Werner  Lemberg.    It  also  supports
+        anti-aliased bitmaps (using a slightly extended BDF format).
+
+      * A Type42  font driver, contributed by Roberto  Alameda.  It is
+        still experimental but seems to work relatively well.
+
+      * A PFR  font driver, contributed  by David Turner  himself.  It
+        doesn't  support PFR  hinting --  note that  BitStream  has at
+        least two patents on this format!
+
+
+  III. MISCELLANEOUS
+
+    - The  cache  sub-system has  been  optimized  in important  ways.
+      Cache hits are now significantly faster.  For example, using the
+      CMap cache is about  twice faster than calling FT_Get_Char_Index
+      on most platforms.  Similarly, using an SBit cache is about five
+      times faster  than loading the  bitmaps from a bitmap  file, and
+      300 to  500 times  faster than generating  them from  a scalable
+      format.
+
+      Note that  you should recompile  your sources if you  designed a
+      custom  cache  class for  the  FT2  Cache  subsystem, since  the
+      changes performed are source, but not binary, compatible.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.1.0 and 2.0.9
+
+  I. IMPORTANT BUG FIXES
+
+    - The  TrueType bytecode  interpreter  has been  fixed to  produce
+      _exactly_ the same output as FreeType 1.x.  Previous differences
+      were due  to slightly distinct  fixed-point computation routines
+      used to perform dot products and vector length measurements.
+
+      It seems  that native TrueType hinting  is _extremely_ sensitive
+      to  rounding errors.  The  required vector  computation routines
+      have been optimized and placed within the `ttinterp.c' file.
+
+    - Fixed the parsing of accelerator tables in the PCF font driver.
+
+    - Fixed the Type1 glyph loader  routine used to compute the font's
+      maximum advance width.
+
+
+  II. NEW FEATURES
+
+    - The `configure' script used on Unix systems has been modified to
+      check  that  GNU  Make  is  being used  to  build  the  library.
+      Otherwise,  it  will display  a  message  proposing  to use  the
+      GNUMAKE environment variable to name it.
+
+      The Unix-specific file README.UNX has been modified accordingly.
+
+
+  III. MISCELLANEOUS
+
+    - The  FreeType  License in  `docs/FTL.TXT'  has  been updated  to
+      include  a  proposed preferred  disclaimer.   If  you are  using
+      FreeType in your products, you are encouraged (but not mandated)
+      to use the following text in your documentation:
+
+      """
+        Portions of this software are copyright © 1996-2002 The
+        FreeType Project (www.freetype.org).  All rights reserved.
+      """
+
+    - The default size of the render pool has been reduced to 16kByte.
+      This  shouldn't result  in any  noticeable  performance penalty,
+      unless you are  using the engine as-is to  render very large and
+      complex glyphs.
+
+    - The  FreeType 2  redesign has  begun.  More  information  can be
+      found at this URL:
+
+        http://www.freetype.org/freetype2/redesign.html
+
+      The following  internal changes  have been performed  within the
+      sources of this release:
+
+        - Many   internal  types   have  been   renamed   to  increase
+          consistency.   The  following  should  be true,  except  for
+          public types:
+
+            * All structure  types have a name ending  in `Rec' (short
+              for `record').
+
+            * A  pointer-to-structure type  has the  same name  as the
+              structure, _without_ the `Rec' suffix.
+
+              Example:
+
+                typedef struct FooRec_
+                {
+                  ...
+
+                } FooRec, *Foo;
+
+        - Many   internal  macros  have   been  renamed   to  increase
+          consistency.  The following should be true:
+
+            * All  macros  have a  name  beginning  with `FT_'.   This
+              required a few changes like
+
+                ALLOC   => FT_ALLOC
+                FREE    => FT_FREE
+                REALLOC => FT_REALLOC
+
+            * All  macros are completely  UPPERCASE.  This  required a
+              few changes like:
+
+                READ_Short  => FT_READ_SHORT
+                NEXT_Short  => FT_NEXT_SHORT
+                GET_ULongLE => FT_GET_ULONG_LE
+                MEM_Set     => FT_MEM_SET
+                MEM_Copy    => FT_MEM_COPY
+                etc.
+
+            * Whenever   possible,   all   macro  names   follow   the
+              FT_<OBJECT>_<METHOD> pattern.  For example
+
+                ACCESS_Frame   => FT_FRAME_ENTER
+                FORGET_Frame   => FT_FRAME_EXIT
+                EXTRACT_Frame  => FT_FRAME_EXTRACT
+                RELEASE_Frame  => FT_FRAME_RELEASE
+
+                FILE_Pos       => FT_STREAM_POS
+                FILE_Seek      => FT_STREAM_SEEK
+                FILE_Read      => FT_STREAM_READ
+                FILE_ReadAt    => FT_STREAM_READ_AT
+                READ_Fields    => FT_STREAM_READ_FIELDS
+
+        - Many  internal functions  have  been renamed  to follow  the
+          FT_<Object>_<Method> pattern.  For example:
+
+            FT_Seek_Stream       => FT_Stream_Seek
+            FT_Read_Stream_At    => FT_Stream_ReadAt
+            FT_Done_Stream       => FT_Stream_Close
+            FT_New_Stream        => FT_Stream_Open
+            FT_New_Memory_Stream => FT_Stream_OpenMemory
+            FT_Extract_Frame     => FT_Stream_ExtractFrame
+
+          Note that method names do not contain `_'.
+
+        - The FT_ALLOC_ARRAY  and FT_REALLOC_ARRAY have  been replaced
+          with  FT_NEW_ARRAY and  FT_RENEW_ARRAY which  do not  take a
+          type  as the  fourth argument.   Instead, the  array element
+          type  size is computed  automatically from  the type  of the
+          target pointer used.
+
+        - A  new object  class, FT_CMap,  has been  introduced.  These
+          internal  objects are  used to  model character  maps.  This
+          eases  the support  of additional  charmap types  within the
+          engine.
+
+        - A new  configuration file named `ftstdlib.h'  has been added
+          to `include/freetype/config'.  It  is used to define aliases
+          for  _every_ routine  of the  ISO  C library  that the  font
+          engine   uses.    Each    aliases   has   a   `ft_'   prefix
+          (e.g. `ft_strlen' is an alias for `strlen').
+
+          This is  used to  ease the porting  of FreeType 2  to exotic
+          runtime environments where the ISO C Library isn't available
+          (e.g.  XFree86 extension modules).
+
+      More details are available in the `ChangeLog' file.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.9 and 2.0.8
+
+  I. IMPORTANT BUG FIXES
+
+    - Certain fonts like `foxjump.ttf' contain broken name tables with
+      invalid entries and wild offsets.  This caused FreeType to crash
+      when trying to load them.
+
+      The  SFNT `name'  table  loader has  been  fixed to  be able  to
+      support these strange fonts.
+
+      Moreover, the code  in charge of processing this  table has been
+      changed  to always favour  Windows-formatted entries  over other
+      ones.  Hence,  a font that works  on Windows but not  on the Mac
+      will  load cleanly in  FreeType and  report accurate  values for
+      Family & PostScript names.
+
+    - The CID font driver has been fixed.  It unfortunately returned a
+      Postscript   Font   name   with   a   leading   slash,   as   in
+      `/MunhwaGothic-Regular'.
+
+    - FreeType  2 should now  compile fine  on AIX  4.3.3 as  a shared
+      library.
+
+    - A  bug  in the  Postscript  hinter  has  been found  and  fixed,
+      removing un-even stem widths at small pixel sizes (like 14-17).
+
+      This  improves the  quality of  a certain  number  of Postscript
+      fonts.
+
+
+  II. NEW FEATURES
+
+    - A  new function  named  `FT_Library_Version' has  been added  to
+      return  the current  library's major,  minor, and  patch version
+      numbers.   This is  important since  the  macros FREETYPE_MAJOR,
+      FREETYPE_MINOR,  and  FREETYPE_PATCH  cannot  be used  when  the
+      library is dynamically linked by a program.
+
+    - Two   new  APIs   have  been   added:   `FT_Get_First_Char'  and
+      `FT_Get_Next_Char'.
+
+      Together,  these can  be used  to iterate  efficiently  over the
+      currently  selected  charmap of  a  given  face.   Read the  API
+      reference for more details.
+
+
+  III. MISCELLANEOUS
+
+    - The FreeType sources are  under heavy internal re-factoring.  As
+      a consequence,  we have created  a branch named `STABLE'  on the
+      CVS to hold all future releases/fixes in the 2.0.x family.
+
+      The  HEAD  branch  now  contains  the  re-factored  sources  and
+      shouldn't  be used for  testing or  packaging new  releases.  In
+      case you  would like  to access the  2.0.9 sources from  our CVS
+      repository, use the tag `VER-2-0-9'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.8 and 2.0.7
+
+  I. IMPORTANT BUG FIXES
+
+    - There was  a small but  nasty bug in  `freetype-config.in' which
+      caused the `freetype-config' script to fail on Unix.
+
+      This didn't prevent the installation  of the library or even its
+      execution, but caused problems  when trying to compile many Unix
+      packages that depend on it.
+
+    - Some TrueType or OpenType fonts embedded in PDF documents do not
+      have  a  'cmap',  'post'  and  'name'  as  is  required  by  the
+      specification.  FreeType no longer refuses to load such fonts.
+
+    - Various fixes to the PCF font driver.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.7 and 2.0.6
+
+  I. IMPORTANT BUG FIXES
+
+    - Fixed  two  bugs in  the  Type 1  font  driver.   The first  one
+      resulted in a memory leak in subtle cases.  The other one caused
+      FreeType to crash when  trying to load `.gsf' files (Ghostscript
+      so-called Postscript fonts).
+
+      (This  made _many_  KDE applications  crash on  certain systems.
+       FreeType _is_ becoming a critical system component on Linux :-)
+
+    - Fixed a memory leak in the CFF font driver.
+
+    - Fixed a memory leak in the PCF font driver.
+
+    - Fixed       the        Visual       C++       project       file
+      `builds/win32/visualc/freetype.dsp' since  it didn't include the
+      Postscript hinter component, causing errors at build time.
+
+    - Fixed a  small rendering bug  in the anti-aliased  renderer that
+      only  occurred when  trying to  draw  thin (less  than 1  pixel)
+      strokes.
+
+    - Fixed  `builds/unix/freetype2.a4' which  is used  to  generate a
+      valid `freetype2.m4' for use with autoconf.
+
+    - Fixed the OpenVMS Makefiles.
+
+
+  II. MISCELLANEOUS
+
+    - Added  `configure'  and   `install'  scripts  to  the  top-level
+      directory.  A GNU-style installation is thus now easily possible
+      with
+
+        ./configure  <options>
+        make
+        make install
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.6 and 2.0.5
+
+  I. IMPORTANT BUG FIXES
+
+    - It wasn't possible to load embedded bitmaps when the auto-hinter
+      was used.  This is now fixed.
+
+    - The TrueType  font driver  didn't load some  composites properly
+      (the  sub-glyphs  were  slightly  shifted,  and  this  was  only
+      noticeable when using monochrome rendering).
+
+    - Various  fixes  to the  auto-hinter.   They  merely improve  the
+      output of sans-serif fonts.   Note that there are still problems
+      with serifed fonts and composites (accented characters).
+
+    - All scalable  font drivers erroneously  returned un-fitted glyph
+      advances when hinting was  requested.  This created problems for
+      a number  of layout applications.  This  is a very  old bug that
+      got  undetected mainly  because most  test/demo  program perform
+      rounding explicitly or implicitly (through the cache).
+
+    - `FT_Glyph_To_Bitmap' did erroneously  modify the source glyph in
+      certain cases.
+
+    - `glnames.py'  still contained  a bug  that made  FreeType return
+      invalid names for certain glyphs.
+
+    - The  library crashed  when  loading certain  Type  1 fonts  like
+      `sadn.pfb'  (`Stalingrad  Normal'),   which  appear  to  contain
+      pathetic font info dictionaries.
+
+    - The TrueType glyph  loader is now much more  paranoid and checks
+      everything when loading a given glyph image.  This was necessary
+      to avoid problems (crashes and/or memory overwrites) with broken
+      fonts that came from a really buggy automatic font converter.
+
+
+  II. IMPORTANT UPDATES AND NEW FEATURES
+
+    - Important updates to the Mac-specific parts of the library.
+
+    - The caching sub-system has  been completely re-designed, and its
+      API has  evolved (the  old one is  still supported  for backward
+      compatibility).
+
+      The documentation for it is  not yet completed, sorry.  For now,
+      you are encouraged to continue  using the old API.  However, the
+      ftview  demo program in  the ft2demos  package has  already been
+      updated to use the new caching functions.
+
+    - A new charmap cache is provided too.  See `FTC_CMapCache'.  This
+      is useful to perform  character code -> glyph index translations
+      quickly, without the need for an opened FT_Face.
+
+    - A NEW POSTSCRIPT HINTER module  has been added to support native
+      hints in  the following  formats: PostScript Type  1, PostScript
+      CID, and CFF/CEF.
+
+      Please test!  Note that  the auto-hinter produces better results
+      for a number of  badly-hinted fonts (mostly auto-generated ones)
+      though.
+
+    - A memory debugger is now  part of the standard FreeType sources.
+      To      enable      it,      define      FT_DEBUG_MEMORY      in
+      <freetype/config/ftoption.h>, and recompile the library.
+
+      Additionally, define  the _environment_ variable FT_DEBUG_MEMORY
+      and run any program using FreeType.  When the library is exited,
+      a  summary  of memory  footprints  and  possible  leaks will  be
+      displayed.
+
+      This works transparently with  _any_ program that uses FreeType.
+      However, you  will need a lot  of memory to  use this (allocated
+      blocks are never  released to the heap to  detect double deletes
+      easily).
+
+
+  III. MISCELLANEOUS
+
+    - We  are  aware  of  subtle  differences between  the  output  of
+      FreeType  versions   1  and  2  when  it   comes  to  monochrome
+      TrueType-hinted glyphs.   These are  most probably due  to small
+      differences in the monochrome rasterizers and will be worked out
+      in an upcoming release.
+
+    - We have decided to fork the sources in a `stable' branch, and an
+      `unstable' one, since FreeType  is becoming a critical component
+      of many Unix systems.
+
+      The next  bug-fix releases of  the library will be  named 2.0.7,
+      2.0.8, etc.,  while the `2.1'  branch will contain a  version of
+      the sources where we will start major reworking of the library's
+      internals, in order to produce FreeType 2.2.0 (or even 3.0) in a
+      more distant future.
+
+      We  also hope  that this  scheme will  allow much  more frequent
+      releases than in the past.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.5 and 2.0.4
+
+  NOTE THAT 2.0.5 DOES NOT CONTAIN THE POSTSCRIPT HINTER.  THIS MODULE
+  WILL BE PART OF THE NEXT RELEASE (EITHER 2.0.6 or 2.1)
+
+  - Fixed a bug that made  certain glyphs, like `Cacute', `cacute' and
+    `lslash'  unavailable from Unicode  charmaps of  Postscript fonts.
+    This prevented the correct display of Polish text, for example.
+
+  - The kerning table of Type 1 fonts was loaded by FreeType, when its
+    AFM    file    was    attached    to    its    face,    but    the
+    FT_FACE_FLAG_HAS_KERNING   bit  flags   was  not   set  correctly,
+    preventing FT_Get_Kerning to return meaningful values.
+
+  - Improved  SFNT (TrueType  & OpenType)  charmap  support.  Slightly
+    better performance, as well as support for the new formats defined
+    by the OpenType 1.3 specification (8, 10, and 12)
+
+  - Fixed a  serious typo in `src/base/ftcalc.c'  which caused invalid
+    computations in certain rare cases, producing ugly artefacts.
+
+  - The  size  of the  EM  square is  computed  with  a more  accurate
+    algorithm for Postscript fonts.   The old one caused slight errors
+    with embedded fonts found in PDF documents.
+
+  - Fixed  a  bug in  the  cache  manager  that prevented  normal  LRU
+    behaviour  within the cache  manager, causing  unnecessary reloads
+    (for FT_Face and FT_Size objects only).
+
+  - Added  a new  function named  `FT_Get_Name_Index' to  retrieve the
+    glyph index of a given glyph name, when found in a face.
+
+  - Added  a new function  named `FT_Get_Postscript_Name'  to retrieve
+    the `unique' Postscript font name of a given face.
+
+  - Added   a   new   public   header  size   named   FT_SIZES_H   (or
+    <freetype/ftsizes.h>) providing  new FT_Size-management functions:
+    FT_New_Size, FT_Activate_Size, FT_Done_Size.
+
+  - Fixed a  reallocation bug that  generated a dangling  pointer (and
+    possibly    memory    leaks)    with    Postscript    fonts    (in
+    src/psaux/psobjs.c).
+
+  - Many fixes for 16-bit correctness.
+
+  - Removed many pedantic compiler warnings from the sources.
+
+  - Added an Amiga build directory in `builds/amiga'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.4 and 2.0.3
+
+  - Fixed a rather annoying bug that was introduced in 2.0.3.  Namely,
+    the font  transformation set through  FT_Set_Transform was applied
+    twice to auto-hinted glyphs, resulting in incorrectly rotated text
+    output.
+
+  - Fixed _many_  compiler warnings.   FT2 should now  compile cleanly
+    with Visual  C++'s most pedantic warning level  (/W4).  It already
+    compiled fine with GCC and a few other compilers.
+
+  - Fixed a bug  that prevented the linear advance  width of composite
+    TrueType glyphs to be correctly returned.
+
+  - Fixed    the    Visual    C++    project    files    located    in
+    `builds/win32/visualc' (previous versions  used older names of the
+    library).
+
+  - Many  32-bit constants  have an  `L' appended  to their  value, in
+    order to improve the 16-bitness  of the code.  Someone is actually
+    trying to use FT2 on an Atari ST machine!
+
+  - Updated  the  `builds/detect.mk' file  in  order to  automatically
+    build FT2  on AIX systems.   AIX uses `/usr/sbin/init'  instead of
+    `/sbin/init' and wasn't previously  detected as a Unix platform by
+    the FreeType build system.
+
+  - Updated  the  Unix-specific  portions  of the  build  system  (new
+    libtool version, etc.).
+
+  - The  SFNT kerning  loader now  ensures  that the  table is  sorted
+    (since some problem fonts do not meet this requirement).
+
+
+=======================================================================
+
+CHANGES BETWEEN 2.0.3 and 2.0.2
+
+  I. CHANGES TO THE MODULES / FONT DRIVERS
+
+    - THE  AUTO-HINTER HAS  BEEN SLIGHTLY  IMPROVED, in  order  to fix
+      several annoying artefacts, mainly:
+
+        - Blue  zone alignment  of  horizontal stems  wasn't performed
+          correctly, resulting in artefacts  like the `d' being placed
+          one pixel below the `b' in some fonts like Time New Roman.
+
+        - Overshoot thresholding  wasn't performed correctly, creating
+          unpleasant artefacts at large character pixel sizes.
+
+        - Composite glyph loading has  been simplified.  This gets rid
+          of  various artefacts  where the  components of  a composite
+          glyphs were not correctly spaced.
+
+      These are  the last changes to the  current auto-hinting module.
+      A new  hinting sub-system is currently  in the work  in order to
+      support native hints  in Type 1 / CFF /  OpenType fonts, as well
+      as globally improve rendering.
+
+    - The  PCF  driver has  been  fixed.   It  reported invalid  glyph
+      dimensions for the fonts available on Solaris.
+
+    - The Type  1, CID and CFF  drivers have been modified  to fix the
+      computation of the EM size.
+
+    - The Type 1  driver has been fixed to avoid  a dangerous bug that
+      crashed the library with non-conforming fonts (i.e. ones that do
+      not place the .notdef glyph at position 0).
+
+    - The TrueType  driver had a  rather subtle bug  (dangling pointer
+      when loading  composite glyphs) that could crash  the library in
+      rare occasions!
+
+
+  II. HIGH-LEVEL API CHANGES
+
+    - The error  code enumeration values have been  changed.  An error
+      value  is decomposed  in  a  generic error  code,  and a  module
+      number.  see <freetype/fterrors.h> for details.
+
+    - A   new  public   header   file  has   been  introduced,   named
+      FT_TRIGONOMETRY_H    (include/freetype/fttrigon.h),    providing
+      trigonometric functions to  compute sines, cosines, arctangents,
+      etc. with 16.16 fixed precision.  The implementation is based on
+      the CORDIC  algorithm and is very fast  while being sufficiently
+      accurate.
+
+
+  III. INTERNALS
+
+    - Added  BeOS-specific files  in the  old build  sub-system.  Note
+      that no changes were required to compile the library with Jam.
+
+    - The  configuration  is now  capable  of automatically  detecting
+      64-bit integers  on a set  of predefined compilers  (GCC, Visual
+      C++, Borland C++) and will use them by default.  This provides a
+      small performance boost.
+
+    - A  small memory leak  that happened  when opening  0-sized files
+      (duh!)  have been fixed.
+
+    - Fixed bezier  stack depth  bug in the  routines provided  by the
+      FT_BBOX_H  header   file.   Also  fixed  similar   bugs  in  the
+      rasterizers.
+
+    - The outline bounding  box code has been rewritten  to use direct
+      computations,  instead of  bezier sub-division,  to  compute the
+      exact bounding box of glyphs.   This is slightly slower but more
+      accurate.
+
+    - The build system has been  improved and fixed, mainly to support
+      `make'  on Windows  2000  correctly, avoid  problems with  `make
+      distclean' on non Unix systems, etc.
+
+    - Hexadecimal  constants  have been  suffixed  with  `U' to  avoid
+      problems with certain compilers on 64-bit platforms.
+
+    - A new directory named `src/tools' has been created.  It contains
+      Python scripts and simple unit test programs used to develop the
+      library.
+
+    - The DocMaker tool has been  moved from `docs' to `src/tools' and
+      has been updated with the following:
+
+         - Now accepts the `--title=XXXX' or `-t XXXX' option from the
+           command line to set the project's name in the generated API
+           reference.
+
+         - Now accepts the `--output=DIR'  or `-o DIR' option from the
+           command line to set  the output directory for all generated
+           HTML files.
+
+         - Now accepts the `--prefix=XXXX' or `-p XXX' option from the
+           command  line  to  set  the  file prefix  to  use  for  all
+           generated HTML files.
+
+         - Now generates the current  time/data on each generated page
+           in order to distinguish between versions.
+
+      DocMaker  can be  used with  other  projects now,  not only  FT2
+      (e.g. MLib, FTLayout, etc.).
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.2 and 2.0.1
+
+  I. CHANGES TO THE MODULES / FONT DRIVERS
+
+    - THE TRUETYPE BYTECODE INTERPRETER IS NOW TURNED OFF, in order to
+      avoid legal problems  with the Apple patents.  It  seems that we
+      mistakenly  turned this option  on in  previous releases  of the
+      build.
+
+      Note that if  you want to use the  bytecode interpreter in order
+      to get high-quality TrueType  rendering, you will need to toggle
+      by        hand        the        definition        of        the
+      TT_CONFIG_OPTION_BYTECODE_INTERPRETER   macro    in   the   file
+      `include/freetype/config/ftoption.h'.
+
+    - The CFF driver has been improved by Tom Kacvinsky and Sander van
+      der Wal:
+
+      * Support for `seac' emulation.
+      * Support for `dotsection'.
+      * Support for retrieving glyph names through
+        `FT_Get_Glyph_Name'.
+
+      The first two items are necessary to correctly a large number of
+      Type 1 fonts converted to the CFF formats by Adobe Acrobat.
+
+    - The Type 1 driver was also improved by Tom & others:
+
+      * Better EM size computation.
+      * Better support for synthetic (transformed) fonts.
+      * The  Type 1  driver returns  the charstrings  corresponding to
+        each glyph in the  `glyph->control_data' field after a call to
+        `FT_Load_Glyph' (thanks Ha Shao).
+
+    - Various other bugfixes, including the following:
+
+      * Fixed a nasty memory leak in the Type 1 driver.
+      * The autohinter  and the pcf  driver used static  writable data
+        when they shouldn't.
+      * Many casts were added to  make the code more 64-bits safe.  It
+        also now compiles on Windows XP 64-bits without warnings.
+      * Some incorrect writable statics were removed in the `autohint'
+        and `pcf' drivers.  FreeType 2 now compiles on Epoc again.
+
+
+  II. CHANGES TO THE HIGH-LEVEL API
+
+    - The library header files inclusion scheme has been changed.  The
+      old scheme looked like:
+
+        #include <freetype/freetype.h>
+        #include <freetype/ftglyph.h>
+        #include <freetype/ftcache.h>
+        #include <freetype/cache/ftimage.h>
+
+      Now you should use:

+        #include FT_FREETYPE_H
+        #include FT_GLYPH_H
+        #include FT_CACHE_H
+        #include FT_CACHE_IMAGE_H
+
+      NOTE THAT  THE OLD  INCLUSION SCHEME WILL  STILL WORK  WITH THIS
+      RELEASE.  HOWEVER, WE  DO NOT GUARANTEE THAT THIS  WILL STILL BE
+      TRUE IN THE NEXT ONE (A.K.A. FREETYPE 2.1).

+
+  III. CHANGES TO THE BUILD PROCESS
+
+    - If you  are not  building FreeType 2  with its own  build system
+      (but with your own Makefiles or project files), you will need to
+      be  aware that  the  build  process has  changed  a little  bit.
+
+      You don't  need to put the  `src' directory in  the include path
+      when  compiling  any FT2  component.   Instead,  simply put  the
+      component's directory in the current include path.
+
+      So, if you were doing something like:
+
+        cc -c -Iinclude -Isrc src/base/ftbase.c
+
+      change the line to:
+
+        cc -c -Iinclude -Isrc/base src/base/ftbase.c
+
+      If you were doing something like:
+
+        cd src/base
+        cc -c -I../../include -I.. ftbase.c
+
+      change it to:
+
+        cd src/base
+        cc -c -I../../include ftbase.c
+
+
+======================================================================
+
+CHANGES BETWEEN 2.0.1 and 2.0
+
+  2.0.1 introduces a few changes:
+
+    - Fixed many bugs related to  the support of CFF / OpenType fonts.
+      These  formats are  now much  better supported  though  there is
+      still work planned to  deal with charset tables and PDF-embedded
+      CFF files that use the old `seac' command.
+
+    - The  library could not  be compiled  in debug  mode with  a very
+      small  number   of  C  compilers   whose  pre-processors  didn't
+      implement the `##'  directive correctly (i.e. per se  the ANSI C
+      specification!)  An elegant fix was found.
+
+    - Added  support for  the  free Borland  command-line C++  Builder
+      compiler.   Use `make  setup bcc32'.   Also fixed  a  few source
+      lines that generated new warnings with BCC32.
+
+    - Fixed a bug in FT_Outline_Get_BBox when computing the extrema of
+      a conic Bezier arc.
+
+    - Updated the INSTALL file to add IDE compilation.
+
+    - Other  minor bug  fixes,  from  invalid Type  1  style flags  to
+      correct   support   of  synthetic   (obliqued)   fonts  in   the
+      auto-hinter, better support for embedded bitmaps in a SFNT font.
+
+    - Fixed some problems with `freetype-config'.
+
+  Finally, the `standard' scheme for including FreeType headers is now
+  gradually changing,  but this will  be explained in a  later release
+  (probably 2.0.2).
+
+  And very  special thanks to Tom Kacvinsky  and YAMANO-UCHI Hidetoshi
+  for their contributions!
+
+
+======================================================================
+
+CHANGES BETWEEN beta8 and 2.0
+
+  - Changed  the default  installation  path for  public headers  from
+    `include/freetype' to `include/freetype2'.
+
+    Also added a new `freetype-config' that is automatically generated
+    and installed  on Unix and  Cygwin systems.  The script  itself is
+    used to retrieve the current  install path, C compilation flags as
+    well as linker flags.
+
+  - Fixed several small bugs:
+
+    * Incorrect max advance width for fixed-pitch Type 1 fonts.
+    * Incorrect glyph names for certain TrueType fonts.
+    * The  glyph advance  was not  copied when  FT_Glyph_To_Bitmap was
+      called.
+    * The  linearHoriAdvance  and  linearVertAdvance  fields  were not
+      correctly returned for glyphs processed by the auto-hinter.
+    * `type1z'  renamed back to  `type1'; the  old `type1'  module has
+      been removed.
+
+  - Revamped the  build system  to make it  a lot more  generic.  This
+    will  allow us  to  re-use  nearly un-modified  in  lots of  other
+    projects (including FreeType Layout).
+
+  - Changed `cid' to use `psaux' too.
+
+  - Added the  cache sub-system.  See <freetype/ftcache.h>  as well as
+    the sources  in `src/cache'.  Note  that it compiles but  is still
+    untested for now.
+
+  - Updated `docs/docmaker.py', a draft  API reference is available at
+    http://www.freetype.org/ft2api.html.
+
+  - Changed `type1' to use `psaux'.
+
+  - Created a  new module named  `psaux' to hold  the Type 1 &  Type 2
+    parsing routines.  It should be  used by `type1', `cid', and `cff'
+    in the future.
+
+  - Fixed an important bug in `FT_Glyph_Get_CBox'.
+
+  - Fixed  some compiler  warnings  that happened  since the  TrueType
+    bytecode decoder was deactivated by default.
+
+  - Fixed two memory leaks:
+
+    * The    memory   manager   (16    bytes)   isn't    released   in
+      FT_Done_FreeType!
+    * Using custom input streams, the  copy of the original stream was
+      never released.
+
+  - Fixed the  auto-hinter by performing automatic  computation of the
+    `filling direction' of each glyph.   This is done through a simple
+    and  fast approximation, and  seems to  work (problems  spotted by
+    Werner though).  The Arphic fonts are a lot nicer though there are
+    still a lot of things to do to handle Asian fonts correctly.
+
+
+======================================================================
+
+BETA-8 (RELEASE CANDIDATE) CHANGES
+
+  - Deactivated the TrueType bytecode interpreter by default.
+
+  - Deactivated the `src/type1' font driver.  Now `src/type1z' is used
+    by default.
+
+  - Updates to the build system.  We now compile the library correctly
+    under  Unix  system  through  `configure' which  is  automatically
+    called on the first `make' invocation.
+
+  - Added the auto-hinting module!  Fixing some bugs here and there.
+
+  - Found some bugs in the  composite loader (seac) of the Type1-based
+    font drivers.
+
+  - Renamed the directory `freetype2/config' to `freetype2/builds' and
+    updated all relevant files.
+
+  - Found a memory leak in the `type1' driver.
+
+  - Incorporated Tom's patches to  support flex operators correctly in
+    OpenType/CFF fonts.  Now all I need is to support pure CFF and CEF
+    fonts to be done with this driver :-)
+
+  - Added the  Windows FNT/FON driver in `src/winfonts'.   For now, it
+    always  `simulates'   a  Unicode  charmap,  so   it  shouldn't  be
+    considered completed right now.
+
+    It  is there  to be  more a  proof of  concept than  anything else
+    anyway.  The driver is a single  C source file, that compiles to 3
+    Kb of code.
+
+    I'm  still working on  the PCF/BDF  drivers, but  I'm too  lazy to
+    finish them now.
+
+  - CHANGES TO THE HIGH-LEVEL API
+
+    * FT_Get_Kerning has a new parameter that allows you to select the
+      coordinates of the kerning  vector (font units, scaled, scaled +
+      grid-fitted).
+    * The  outline functions are  now in <freetype/ftoutln.h>  and not
+      part of <freetype/freetype.h> anymore.
+    * <freetype/ftmodule.h>    now     contains    declarations    for
+       FT_New_Library, FT_Done_Library, FT_Add_Default_Modules.
+    * The so-called convenience  functions have moved from `ftoutln.c'
+      to  `ftglyph.c',  and  are  thus available  with  this  optional
+      component    of   the   library.     They   are    declared   in
+      <freetype/ftglyph.h> now.
+    * Anti-aliased  rendering is now  the default  for FT_Render_Glyph
+      (i.e. corresponds to render_mode == 0 == ft_render_mode_normal).
+      To generate a monochrome bitmap, use ft_render_mode_mono, or the
+      FT_LOAD_MONOCHROME     flag    in    FT_Load_Glyph/FT_Load_Char.
+      FT_LOAD_ANTI_ALIAS is still defined, but values to 0.
+    * <freetype/freetype.h>  now include <freetype/config/ftconfig.h>,
+      solving a few headaches :-)
+    * The type FT_GlyphSlotRec has now a `library' field.
+
+  - CHANGES TO THE `ftglyph.h' API
+
+    This API has  been severely modified in order  to make it simpler,
+    clearer, and more  efficient.  It certainly now looks  like a real
+    `glyph factory'  object, and allows client  applications to manage
+    (i.e.  transform,  bbox  and  render) glyph  images  without  ever
+    knowing their original format.
+
+  - Added  support  for CID-keyed  fonts  to  the  CFF driver.   Maybe
+    support for pure CFF + CEF fonts should come in?
+
+  - Cleaned up  source code in order  to avoid two  functions with the
+    same name.  Also  changed the names of the  files in `type1z' from
+    `t1XXXX' to `z1XXXX' in order to avoid any conflicts.
+
+    `make multi' now works well :-)
+
+    Also removed the use of `cidafm' for now, even if the source files
+    are  still there.  This  functionality will  certainly  go into  a
+    specific module.
+
+  - ADDED SUPPORT FOR THE AUTO-HINTER
+
+    It  works :-) I  have a  demo program  which simply  is a  copy of
+    `ftview'       that      does       a      `FT_Add_Module(library,
+    &autohinter_module_class)' after  library initialization, and Type
+    1 & OpenType/CFF fonts are now hinted.
+
+    CID  fonts are  not hinted,  as they  include no  charmap  and the
+    auto-hinter doesn't include  `generic' global metrics computations
+    yet.
+
+    Now, I need to release this thing to the FreeType 2 source.
+
+  - CHANGES TO THE RENDERER MODULES
+
+    The  monochrome  and smooth  renderers  are  now  in two  distinct
+    directories, namely `src/raster1' and `src/smooth'.  Note that the
+    old `src/renderer' is now gone.
+
+    I ditched  the 5-gray-levels renderers.  Basically,  it involved a
+    simple #define toggle in 'src/raster1/ftraster.c'.
+
+    FT_Render_Glyph,  FT_Outline_Render  &  FT_Outline_Get_Bitmap  now
+    select the best renderer  available, depending on render mode.  If
+    the current renderer for a  given glyph image format isn't capable
+    of supporting  the render mode, another  one will be  found in the
+    library's list.   This means that client applications  do not need
+    to  switch or  set  the  renderers themselves  (as  in the  latest
+    change), they'll get what they want automatically.  At last.
+
+    Changed the demo programs accordingly.
+
+  - MAJOR INTERNAL REDESIGN:
+
+    A lot of internal modifications  have been performed lately on the
+    source in order to provide the following enhancements:
+
+    * More generic module support:
+
+      The FT_Module  type is  now defined to  represent a handle  to a
+      given  module.   The  file  <freetype/ftmodule.h>  contains  the
+      FT_Module_Class definition, as well as the module-loading public
+      API.
+
+      The  FT_Driver type  is still  defined, and  still  represents a
+      pointer to  a font driver.  Note that  FT_Add_Driver is replaced
+      by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc.
+
+    * Support for generic glyph image types:
+
+      The FT_Renderer  type is a pointer  to a module  used to perform
+      various operations on glyph image.
+
+      Each renderer is  capable of handling images in  a single format
+      (e.g. ft_glyph_format_outline).  Its functions are used to:
+
+      - transform an glyph image
+      - render a glyph image into a bitmap
+      - return the control box (dimensions) of a given glyph image
+
+      The scan converters `ftraster.c' and `ftgrays.c' have been moved
+      to the new directory `src/renderer', and are used to provide two
+      default renderer modules.
+
+      One corresponds  to the `standard' scan-converter,  the other to
+      the `smooth' one.
+
+      he  current  renderer  can  be  set  through  the  new  function
+      FT_Set_Renderer.
+
+      The old raster-related function FT_Set_Raster, FT_Get_Raster and
+      FT_Set_Raster_Mode have now disappeared, in favor of the new:
+
+        FT_Get_Renderer
+        FT_Set_Renderer
+
+      See the file <freetype/ftrender.h> for more details.
+
+      These  changes  were  necessary  to properly  support  different
+      scalable formats in the future, like bi-color glyphs, etc.
+
+    * Glyph loader object:
+
+      A  new  internal  object,  called  a  'glyph  loader'  has  been
+      introduced in the base layer.  It is used by all scalable format
+      font drivers to load glyphs and composites.
+
+      This object  has been  created to reduce  the code size  of each
+      driver,  as  each  one  of  them  basically  re-implemented  its
+      functionality.
+
+      See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for
+      more information.
+
+    * FT_GlyphSlot has new fields:
+
+      In  order   to  support  extended  features   (see  below),  the
+      FT_GlyphSlot structure has a few new fields:
+
+      linearHoriAdvance:
+
+        This  field  gives  the   linearly  scaled  (i.e.  scaled  but
+        unhinted) advance  width for the  glyph, expressed as  a 16.16
+        fixed pixel value.  This is useful to perform WYSIWYG text.
+
+      linearVertAdvance:
+        This field  gives the linearly  scaled advance height  for the
+        glyph  (relevant in  vertical  glyph layouts  only).  This  is
+        useful to perform WYSIWYG text.
+
+        Note that  the two above field replace  the removed `metrics2'
+        field in the glyph slot.
+
+      advance:
+        This field is a vector  that gives the transformed advance for
+        the glyph.   By default, it corresponds to  the advance width,
+        unless  FT_LOAD_VERTICAL_LAYOUT  was  specified  when  calling
+        FT_Load_Glyph or FT_Load_Char.
+
+      bitmap_left:
+        This  field gives  the  distance in  integer  pixels from  the
+        current pen position  to the left-most pixel of  a glyph image
+        IF IT IS  A BITMAP.  It is only valid  when the `format' field
+        is set to `ft_glyph_format_bitmap', for example, after calling
+        the new function FT_Render_Glyph.
+
+      bitmap_top:
+        This  field gives  the  distance in  integer  pixels from  the
+        current pen position (located on the baseline) to the top-most
+        pixel of the  glyph image IF IT IS  A BITMAP.  Positive values
+        correspond to upwards Y.
+
+      loader:
+        This  is a  new  private  field for  the  glyph slot.   Client
+        applications should not touch it.
+
+
+    * Support for transforms and direct rendering in FT_Load_Glyph:
+
+      Most of the functionality found in <freetype/ftglyph.h> has been
+      moved to the core library.  Hence, the following:
+
+      - A   transform   can   be   specified  for   a   face   through
+        FT_Set_Transform.  this transform  is applied by FT_Load_Glyph
+        to  scalable glyph  images (i.e.  NOT TO  BITMAPS)  before the
+        function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM
+        was set in the load flags.
+
+      - Once  a  glyph image  has  been  loaded,  it can  be  directly
+        converted  to  a  bitmap  by  using  the  new  FT_Render_Glyph
+        function.  Note that this  function takes the glyph image from
+        the glyph slot,  and converts it to a  bitmap whose properties
+        are returned  in `face.glyph.bitmap', `face.glyph.bitmap_left'
+        and `face.glyph.bitmap_top'.  The  original native image might
+        be lost after the conversion.
+
+      - When using the new  bit flag FT_LOAD_RENDER, the FT_Load_Glyph
+        and   FT_Load_Char   functions   will   call   FT_Render_Glyph
+        automatically when needed.
+
+  - Reformatted all  modules source  code in order  to get rid  of the
+    basic data types redefinitions (i.e. `TT_Int' instead of `FT_Int',
+    `T1_Fixed'  instead  of  `FT_Fixed').  Hence  the  format-specific
+    prefixes like  `TT_', `T1_',  `T2_' and `CID_'  are only  used for
+    relevant structures.
+
+
+======================================================================
+
+OLD CHANGES FOR BETA 7
+
+  - bug-fixed the  OpenType/CFF parser.  It  now loads and displays my
+    two  fonts nicely,  but I'm  pretty certain  that more  testing is
+    needed :-)
+
+  - fixed the crummy Type 1 hinter, it now handles accented characters
+    correctly (well, the accent is  not always well placed, but that's
+    another problem..)
+
+  - added the CID-keyed Type 1 driver in `src/cid'.  Works pretty well
+    for only 13 Kb of code  ;-) Doesn't read AFM files though, nor the
+    really useful CMAP files..
+
+  - fixed  two  bugs  in  the  smooth  renderer  (src/base/ftgrays.c).
+    Thanks to Boris Letocha for spotting them and providing a fix.
+
+  - fixed potential `divide by zero' bugs in ftcalc.c.
+
+  - added source  code for  the OpenType/CFF driver  (still incomplete
+    though..)
+
+  - modified the  SFNT driver slightly  to perform more  robust header
+    checks  in TT_Load_SFNT_Header.  This prevents certain  font files
+    (e.g.  some  Type  1  Multiple  Masters)  from  being  incorrectly
+    `recognized' as TrueType font files..
+
+  - moved a lot of stuff from  the TrueType driver to the SFNT module,
+    this   allows   greater   code   re-use   between   font   drivers
+    (e.g. TrueType, OpenType, Compact-TrueType, etc..)
+
+  - added a tiny segment cache to the SFNT Charmap 4 decoder, in order
+    to minimally speed it up..
+
+  - added  support for  Multiple Master  fonts in  `type1z'.  There is
+    also a new file named <freetype/ftmm.h> which defines functions to
+    manage them from client applications.
+
+    The new file `src/base/ftmm.c' is also optional to the engine..
+
+  - various  formatting changes (e.g.  EXPORT_DEF ->  FT_EXPORT_DEF) +
+    small bug fixes in FT_Load_Glyph, the `type1' driver, etc..
+
+  - a minor fix to the Type 1 driver to let them apply the font matrix
+    correctly (used for many oblique fonts..)
+
+  - some fixes for 64-bit systems (mainly changing some FT_TRACE calls
+    to use %p instead of %lx).  Thanks to Karl Robillard.
+
+  - fixed  some bugs  in  the sbit  loader (src/base/sfnt/ttsbit.c)  +
+    added  a new flag,  FT_LOAD_CROP_BITMAP to  query that  bitmaps be
+    cropped when  loaded from a file  (maybe I should  move the bitmap
+    cropper to the base layer ??).
+
+  - changed the default  number of gray levels of  the smooth renderer
+    to 256  (instead of  the previous 128).  Of course, the  human eye
+    can't see any difference ;-)
+
+  - removed TT_MAX_SUBGLYPHS,  there is no static limit  on the number
+    of subglyphs in a TrueType font now..
+
+
+======================================================================
+
+OLD CHANGES 16 May 2000
+
+  - tagged `BETA-6'  in the  CVS tree.  This one is a  serious release
+    candidate even though it doesn't incorporate the auto-hinter yet..
+
+  - various obsolete files were removed, and copyright header updated
+
+  - finally  updated  the  standard   raster  to  fix  the  monochrome
+    rendering bug + re-enable  support for 5-gray levels anti-aliasing
+    (suck, suck..)
+
+  - created new header files, and modified sources accordingly:
+
+     <freetype/fttypes.h>
+       - simple FreeType types, without the API
+     <freetype/internal/ftmemory.h>
+       - definition of memory-management macros
+
+  - added   the   `DSIG'   (OpenType   Digital   Signature)   tag   to
+    <freetype/tttags.h>
+
+  - light update/cleaning of the build system + changes to the sources
+    in  order  to  get  rid  of _all_  compiler  warnings  with  three
+    compilers, i.e:
+
+    gcc with `-ansi -pedantic -Wall -W', Visual C++ with `/W3 /WX' and
+    LCC
+
+    IMPORTANT NOTE FOR WIN32-LCC USERS:
+    |
+    |  It seems the C pre-processor  that comes with LCC is broken, it
+    |  doesn't  recognize  the  ANSI  standard  directives  #  and  ##
+    |  correctly   when  one  of   the  argument  is  a  macro.  Also,
+    |  something like:
+    |
+    |     #define F(x)  print##x
+    |
+    |     F(("hello"))
+    |
+    |  will get incorrectly translated to:
+    |
+    |     print "hello")
+    |
+    |  by its pre-processor.  For this reason, you simply cannot build
+    |  FreeType 2 in debug mode with this compiler..
+
+  - yet  another massive grunt work.  I've  changed the  definition of
+    the EXPORT_DEF,  EXPORT_FUNC, BASE_DEF &  BASE_FUNC macros.  These
+    now take an argument, which is the function's return value type.
+
+    This  is necessary to  compile FreeType  as a  DLL on  Windows and
+    OS/2.  Depending on the compiler used, a compiler-specific keyword
+    like  __export or __system  must be  placed before  (VisualC++) or
+    after (BorlandC++) the type..
+
+    Of course, this needed a lot of changes throughout the source code
+    to make it compile again...  All cleaned up now, apparently..
+
+    Note also  that there is a  new EXPORT_VAR macro  defined to allow
+    the   _declaration_    of   an   exportable    public   (constant)
+    variable.  This  is  the   case  of  the  raster  interfaces  (see
+    ftraster.h and ftgrays.h), as well as each module's interface (see
+    sfdriver.h, psdriver.h, etc..)
+
+  - new feature: it  is now possible to pass  extra parameters to font
+                 drivers  when creating  a new  face object.  For now,
+                 this capability is unused.  It could however prove to
+                 be useful in a near future..
+
+      the FT_Open_Args structure was  changes, as well as the internal
+      driver interface  (the specific `init_face'  module function has
+      now a different signature).
+
+  - updated the tutorial (not finished though).
+
+  - updated the top-level BUILD  document
+
+  - fixed  a  potential memory  leak  that  could  occur when  loading
+    embedded bitmaps.
+
+  - added     the     declaration     of     FT_New_Memory_Face     in
+    <freetype/freetype.h>, as  it was  missing from the  public header
+    (the implementation was already in `ftobjs.c').
+
+  - the file <freetype/fterrors.h> has been seriously updated in order
+    to allow  the automatic generation  of error message tables.   See
+    the comments within it for more information.
+
+  - major directory  hierarchy re-organisation.  This was done for two
+    things:
+
+      * first,  to ease  the `manual'  compilation of  the  library by
+        requiring at lot less include paths :-)
+
+      * second,  to  allow  external  programs to  effectively  access
+        internal  data  fields.  For example,  this  can be  extremely
+        useful if  someone wants  to write a  font producer or  a font
+        manager on top of FreeType.
+
+    Basically, you  should now use  the 'freetype/' prefix  for header
+    inclusion, as in:
+
+        #include <freetype/freetype.h>
+        #include <freetype/ftglyph.h>
+
+    Some new include sub-directories are available:
+
+     a. the  `freetype/config' directory,  contains two files  used to
+        configure  the  build  of  the  library.  Client  applications
+        should  not need  to look  at these  normally, but they can if
+        they want.
+
+        #include <freetype/config/ftoption.h>
+        #include <freetype/config/ftconfig.h>
+
+     b. the `freetype/internal'  directory, contains header files that
+        describes library  internals.  These are the header files that
+        were  previously  found  in  the `src/base'  and  `src/shared'
+        directories.
+
+
+    As  usual, the build  system and  the demos  have been  updated to
+    reflect the change..
+
+    Here's a layout of the new directory hierarchy:
+
+    TOP_DIR
+      include/
+         freetype/
+            freetype.h
+            ...
+            config/
+              ftoption.h
+              ftconfig.h
+              ftmodule.h
+
+            internal/
+              ftobjs.h
+              ftstream.h
+              ftcalc.h
+              ...
+
+      src/
+         base/
+            ...
+
+         sfnt/
+         psnames/
+         truetype/
+         type1/
+         type1z/
+
+
+    Compiling a module is now  much easier, for example, the following
+    should work when in the TOP_DIR directory on an ANSI build:
+
+       gcc -c -I./include -I./src/base src/base/ftbase.c
+       gcc -c -I./include -I./src/sfnt src/sfnt/sfnt.c
+       etc..
+
+    (of course, using -Iconfig/<system> if you provide system-specific
+     configuration files).
+
+  - updated the structure of FT_Outline_Funcs in order to allow direct
+    coordinate scaling within  the outline decomposition routine (this
+    is  important for virtual  `on' points  with TrueType  outlines) +
+    updates to the rasters to support this..
+
+  - updated  the OS/2  table  loading code  in `src/sfnt/ttload.c'  in
+    order to support version 2 of the table (see OpenType 1.2 spec)
+
+  - created  `include/tttables.h'  and  `include/t1tables.h' to  allow
+    client applications to access some of  the SFNT and T1 tables of a
+    face  with  a  procedural  interface (see  `FT_Get_Sfnt_Table')  +
+    updates to internal source files to reflect the change..
+
+  - some  cleanups in  the source  code to  get rid  of  warnings when
+    compiling with the `-Wall -W -ansi -pedantic' options in gcc.
+
+  - debugged and moved the smooth renderer to `src/base/ftgrays.c' and
+    its header to `include/ftgrays.h'
+
+  - updated TT_MAX_SUBGLYPHS  to 96 as some CJK  fonts have composites
+    with up to 80 sub-glyphs !! Thanks to Werner
+
+
+======================================================================
+
+OLD CHANGES - 14-apr-2000
+
+  - fixed  a bug  in  the  TrueType glyph  loader  that prevented  the
+    correct loading of some CJK glyphs in mingli.ttf
+
+  - improved the standard Type 1 hinter in `src/type1'
+
+  - fixed two bugs  in the experimental Type 1  driver in `src/type1z'
+    to handle the new XFree86 4.0 fonts (and a few other ones..)
+
+  - the smooth  renderer is now  complete and supports  sub-banding to
+    render large glyphs  at high speed.  However, it is still  located
+    in `demos/src/ftgrays.c' and should move to the  library itself in
+    the next  beta.  NOTE: The  smooth  renderer  doesn't  compile  in
+    stand-alone mode anymore, but this should be fixed RSN..
+
+  - introduced convenience  functions to  more easily deal  with glyph
+    images, see  `include/ftglyph.h' for more details, as  well as the
+    new  demo program  named `demos/src/ftstring.c'  that demonstrates
+    its use
+
+  - implemented  FT_LOAD_NO_RECURSE in  both the  TrueType and  Type 1
+    drivers  (this  is required  by  the  auto-hinter  to improve  its
+    results).
+
+  - changed   the  raster   interface,  in   order  to   allow  client
+    applications  to   provide  their   own  span-drawing   callbacks.
+    However,   only   the   smooth   renderer   supports   this.   See
+    `FT_Raster_Params' in the file `include/ftimage.h'.
+
+  - fixed  a small bug  in FT_MulFix  that caused  incorrect transform
+    computation!
+
+  - Note: The tutorial is out-of-date.
+
+
+======================================================================
+
+OLD CHANGES - 12-mar-2000
+
+  - changed  the  layout  of  configuration  files  :  now,  all  ANSI
+    configuration         files         are         located         in
+    `freetype2/config'.  System-specific over-rides  can be  placed in
+    `freetype2/config/<system>'.
+
+  - moved all configuration macros to `config/ftoption.h'
+
+  - improvements in the Type 1 driver with AFM support
+
+  - changed the fields  in the FT_Outline structure :  the old `flags'
+    array is re-named `tags', while all ancient flags are encoded into
+    a single unsigned int named `flags'.
+
+  - introduced     new      flags     in     FT_Outline.flags     (see
+    ft_outline_.... enums in `ftimage.h').
+
+  - changed outline functions to `FT_Outline_<action>' syntax
+
+  - added a smooth anti-alias renderer to the demonstration programs
+
+  - added Mac graphics driver (thanks Just)
+
+  - FT_Open_Face  changed  in  order   to  received  a  pointer  to  a
+    FT_Open_Args descriptor..
+
+  - various  cleanups,  a  few  more API  functions  implemented  (see
+    FT_Attach_File)
+
+  - updated some docs
+
+
+======================================================================
+
+OLD CHANGES - 22-feb-2000
+
+  - introduced the `psnames' module.  It is used to:
+
+      o convert  a Postscript glyph  name into the  equivalent Unicode
+        character code (used by the  Type 1 driver(s) to synthesize on
+        the fly a Unicode charmap).
+
+      o provide an  interface to retrieve the Postscript  names of the
+        Macintosh,  Adobe  Standard &  Adobe  Expert character  codes.
+        (the Macintosh  names are  used by the  SFNT-module postscript
+        names support routines, while the other two tables are used by
+        the Type 1 driver(s)).
+
+  - introduced the `type1z' alternate Type 1 driver.  This is a (still
+    experimental) driver  for the Type  1 format that  will ultimately
+    replace the one  in `src/type1'.  It uses pattern matching to load
+    data from the font, instead of a finite  state analyzer.  It works
+    much better than the `old' driver with `broken' fonts.  It is also
+    much smaller (under 15 Kb).
+
+  - the  Type 1  drivers (both  in `src/type1'  and  `src/type1z') are
+    nearly  complete.  They  both  provide automatic  Unicode  charmap
+    synthesis through  the `psnames' module.  No re-encoding vector is
+    needed.  (note  that they  still  leak  memory  due to  some  code
+    missing, and I'm getting lazy).
+
+    Trivial AFM support has been added to read kerning information but
+    wasn't exactly tested as it should ;-)
+
+  - The TrueType  glyph loader has  been seriously rewritten  (see the
+    file  `src/truetype/ttgload.c'.  It is now  much, much  simpler as
+    well as  easier to read,  maintain and understand  :-) Preliminary
+    versions introduced a  memory leak that has been  reported by Jack
+    Davis, and is now fixed..
+
+  - introduced  the new  `ft_glyph_format_plotter', used  to represent
+    stroked outlines  like Windows `Vector' fonts, and  certain Type 1
+    fonts  like `Hershey'.  The corresponding  raster will  be written
+    soon.
+
+  - FT_New_Memory_Face  is  gone.  Likewise,  FT_Open_Face has  a  new
+    interface that uses a structure  to describe the input stream, the
+    driver (if required), etc..
+
+
+TODO
+
+  - Write FT_Get_Glyph_Bitmap and FT_Load_Glyph_Bitmap
+
+  - Add a function like FT_Load_Character(face, char_code, load_flags)
+    that  would   really  embed  a  call   to  FT_Get_Char_Index  then
+    FT_Load_Glyph to ease developer's work.
+
+  - Update the tutorial!
+
+  - consider adding  support for Multiple  Master fonts in the  Type 1
+    drivers.
+
+  - Test the AFM routines of the  Type 1 drivers to check that kerning
+    information is returned correctly.
+
+  - write a decent auto-gridding component  !! We need this to release
+    FreeType 2.0 gold !
+
+
+less urgent needs:
+
+  - add a CFF/Type2 driver
+  - add a BDF driver
+  - add a FNT/PCF/HBF driver
+  - add a Speedo driver from the X11 sources
+
+
+======================================================================
+
+OLDER CHANGES - 27-jan-2000
+
+  - updated the  `sfnt' module  interface to allow  several SFNT-based
+    drivers to co-exist peacefully
+
+  - updated  the `T1_Face'  type  to better  separate Postscript  font
+    content  from the  rest of  the FT_Face  structure.  Might be used
+    later by the CFF/Type2 driver..
+
+  - added an experimental replacement Type 1 driver featuring advanced
+    (and speedy) pattern matching to retrieve the data from postscript
+    fonts.
+
+  - very minor  changes in the implementation  of FT_Set_Char_Size and
+    FT_Set_Pixel_Sizes (they now implement default to lighten the font
+    driver's code).
+
+
+======================================================================
+
+OLD MESSAGE
+
+This file summarizes the changes  that occurred  since the last `beta'
+of FreeType 2. Because the list is important, it has been divided into
+separate sections:
+
+Table Of Contents:
+
+    I   High-Level Interface (easier !)
+   II   Directory Structure
+  III   Glyph Image Formats
+   IV   Build System
+    V   Portability
+   VI   Font Drivers
+
+
+----------------------------------------------------------------------
+
+High-Level Interface:
+
+  The high-level API has been considerably simplified.  Here is how:
+
+    - resource objects have disappeared.  this means that face objects
+      can now be created with  a single function call (see FT_New_Face
+      and FT_Open_Face)
+
+    - when calling  either FT_New_Face  & FT_Open_Face, a  size object
+      and a glyph slot object  are automatically created for the face,
+      and can  be accessed  through `face->glyph' and  `face->size' if
+      one really  needs to.   In most cases,  there's no need  to call
+      FT_New_Size or FT_New_Glyph.
+
+    - similarly,  FT_Load_Glyph  now  only  takes  a  `face'  argument
+      (instead  of a  glyph  slot  and a  size).  Also,  its  `result'
+      parameter is  gone, as the glyph  image type is  returned in the
+      field `face->glyph.format'
+
+    - the list  of available  charmaps is directly  accessible through
+      `face->charmaps', counting `face->num_charmaps'  elements.  Each
+      charmap  has an  'encoding'  field which  specifies which  known
+      encoding it deals with.  Valid values are, for example:
+
+          ft_encoding_unicode      (for ASCII, Latin-1 and Unicode)
+          ft_encoding_apple_roman
+          ft_encoding_sjis
+          ft_encoding_adobe_standard
+          ft_encoding_adobe_expert
+
+      other  values may  be added  in the  future.  Each charmap still
+      holds  its `platform_id'  and `encoding_id'  values in  case the
+      encoding is too exotic for the current library
+
+
+----------------------------------------------------------------------
+
+Directory Structure:
+
+  Should seem obvious to most of you:
+
+     freetype/
+         config/        -- configuration sub-makefiles
+            ansi/
+            unix/       -- platform-specific configuration files
+            win32/
+            os2/
+            msdos/
+
+         include/       -- public header  files, those to  be included
+                           directly by client apps
+
+         src/           -- sources of the library
+           base/        -- the base layer
+           sfnt/        -- the sfnt `driver'  (see the drivers section
+                           below)
+           truetype/    -- the truetype driver
+           type1/       -- the type1 driver
+           shared/      -- some header files shared between drivers
+
+         demos/         -- demos/tools
+
+         docs/          -- documentation (a bit empty for now)
+
+
+----------------------------------------------------------------------
+
+Glyph Image Formats:
+
+  Drivers are now able to  register new glyph image formats within the
+  library.  For  now, the  base layer supports  of course  bitmaps and
+  vector  outlines, but  one  could imagine  something different  like
+  colored bitmaps, bi-color vectors or whatever else (Metafonts anyone
+  ??).
+
+  See  the   file  `include/ftimage.h'.   Note  also  that   the  type
+  FT_Raster_Map  is gone,  and  is now  replaced  by FT_Bitmap,  which
+  should encompass all known bitmap types.
+
+  Each new  image format  must provide at  least one `raster',  i.e. a
+  module capable of  transforming the glyph image into a bitmap.  It's
+  also possible  to change the default  raster used for  a given glyph
+  image format.
+
+  The default outline  scan-converter now uses 128 levels  of grays by
+  default,  which tends  to smooth  many  things.  Note that the  demo
+  programs have been updated significantly in order to display these..
+
+
+----------------------------------------------------------------------
+
+Build system:
+
+  You still need  GNU Make to build the library.  The build system has
+  been very seriously re-vamped in order to provide things like :
+
+   - automatic host platform  detection (reverting to 'config/ansi' if
+     it is not detected, with pseudo-standard compilation flags)
+
+   - the ability to compile from the Makefiles with very different and
+     exotic compilers.  Note that linking the library can be difficult
+     for some platforms.
+
+     For example, the file `config/win32/lcclib.bat' is invoked by the
+     build system to create the `.lib' file with LCC-Win32 because its
+     librarian  has too  many flaws  to be  invoked directly  from the
+     Makefile.
+
+  Here's how it works:
+
+  - the first time you type `make',  the build system runs a series of
+    sub-makefiles  in order  to detect  your host  platform.  It  then
+    dumps what it found, and creates a file called `config.mk' in  the
+    current  directory.  This is a  sub-Makefile used  to  define many
+    important Make variables used to build the library.
+
+  - the second time, the build system detects the `config.mk' then use
+    it  to  build the  library.  All object  files  go  into 'obj'  by
+    default,  as well  as the  library file,  but this  can  easily be
+    changed.
+
+  Note that  you can run `make  setup' to force  another host platform
+  detection  even   if  a  `config.mk'  is  present   in  the  current
+  directory.  Another solution  is  simply to  delete  the file,  then
+  re-run make.
+
+  Finally, the  default compiler  for all platforms  is gcc  (for now,
+  this will hopefully changed in the future).  You can however specify
+  a different  compiler by specifying  it after the 'setup'  target as
+  in:
+
+      gnumake setup lcc         on Win32 to use the LCC compiler
+      gnumake setup visualc     on Win32 to use Visual C++
+
+  See  the file  `config/<system>/detect.mk' for  a list  of supported
+  compilers for your platforms.
+
+  It should be relatively easy  to write new detection rules files and
+  config.mk..
+
+  Finally, to  build the demo programs,  go to `demos'  and launch GNU
+  Make, it will use the `config.mk'  in the top directory to build the
+  test programs..
+
+
+----------------------------------------------------------------------
+
+Portability:
+
+  In  the  previous  beta,  a  single FT_System  object  was  used  to
+  encompass  all  low-level  operations like  thread  synchronisation,
+  memory management and i/o access.  This has been greatly simplified:
+
+    - thread synchronisation  has been dropped, for  the simple reason
+      that the library  is already re-entrant, and that  if you really
+      need  two  threads accessing  the  same  FT_Library, you  should
+      really synchronize access to it yourself with a simple mutex.
+
+    - memory  management is  performed  through a  very simple  object
+      called `FT_Memory',  which really is a table  containing a table
+      of pointers to  functions like malloc, realloc and  free as well
+      as some user data (closure).
+
+    - resources have disappeared (they created more problems than they
+      solved), and  i/o management have  been simplified greatly  as a
+      result.  Streams are  defined through  FT_Stream objects,  which
+      can be either memory-based or disk-based.
+
+      Note that  each face  has its own  stream, which is  closed only
+      when  the  face object  is  destroyed.  Hence,  a function  like
+      TT_Flush_Face in 1.x cannot be directly  supported.  However, if
+      you really need something like  this, you can easily tailor your
+      own streams  to achieve the same  feature at a  lower level (and
+      use FT_Open_Face instead of FT_New_Face to create the face).
+
+  See the file  `include/ftsystem.h' for more details, as  well as the
+  implementations found in `config/unix' and `config/ansi'.
+
+
+----------------------------------------------------------------------
+
+Font Drivers:
+
+  The  Font Driver  interface has  been modified  in order  to support
+  extensions & versioning.
+
+
+  The  list of  the font  drivers that  are statically  linked  to the
+  library at compile time is  managed through a new configuration file
+  called `config/<platform>/ftmodule.h'.
+
+  This  file is  autogenerated  when  invoking  `make modules'.   This
+  target  will  parse  all  sub-directories  of  'src', looking  for a
+  `module.mk' rules  file, used  to describe  the driver to  the build
+  system.
+
+  Hence, one  should call  `make modules' each  time a font  driver is
+  added or removed from the `src' directory.
+
+  Finally, this  version  provides  a `pseudo-driver'  in  `src/sfnt'.
+  This  driver  doesn't  support  font  files  directly, but  provides
+  services used by all TrueType-like font drivers.  Hence, its code is
+  shared between  the TrueType & OpenType  font formats,  and possibly
+  more formats to come if we're lucky..
+
+
+----------------------------------------------------------------------
+
+Extensions support:
+
+  The extensions support is inspired by the one found in 1.x.
+
+  Now, each font driver has  its own `extension registry', which lists
+  which extensions  are available  for the font  faces managed  by the
+  driver.
+
+  Extension ids are  now strings, rather than 4-byte  tags, as this is
+  usually more readable.
+
+  Each extension has:
+    - some data, associated to each face object
+    - an interface (table of function pointers)
+
+  An extension  that is format-specific should  simply register itself
+  to the correct font driver.  Here is some example code:
+
+   // Registering an extensions
+   //
+   FT_Error  FT_Init_XXXX_Extension( FT_Library  library )
+   {
+     FT_DriverInterface*  tt_driver;
+
+     driver = FT_Get_Driver( library, "truetype" );

+How to customize the compilation of the library
+===============================================
+
+  FreeType  is highly  customizable  to fit  various  needs, and  this
+  document  describes  how  it  is  possible  to  select  options  and
+  components at compilation time.
+
+
+I. Configuration macros
+
+  The  file `include/freetype/config/ftoption.h'  contains a  list  of
+  commented configuration macros that can  be toggled by developers to
+  indicate which features should be active while building the library.
+
+  These  options range  from debug  level to  availability  of certain
+  features,   like  native   TrueType  hinting   through   a  bytecode
+  interpreter.
+
+  We  invite you  to read  this file  for more  information.   You can
+  change the  file's content to suit  your needs, or  override it with
+  one of the techniques described below.
+
+
+II. Modules list
+
+  If you  use GNU make  please edit the top-level  file `modules.cfg'.
+  It contains a  list of available FreeType modules  and extensions to
+  be compiled.  Change it to suit your own preferences.  Be aware that
+  certain modules  depend on  others, as described  in the  file.  GNU
+  make  uses `modules.cfg'  to  generate `ftmodule.h'  (in the  object
+  directory).
+
+  If you build FreeType in a directory separate from the source files,
+  put your  customized `modules.cfg' in  that directory; that  way you
+  can keep the source files `clean'.
+
+  If  you don't  use  GNU make  you  have to  manually  edit the  file
+  `include/freetype/config/ftmodule.h' (which  is *not* used  with  if
+  compiled with GNU make) to add  or remove the drivers and components
+  you want  to compile into  the library.  See `INSTALL.ANY'  for more
+  information.
+
+
+III. System interface
+
+  FreeType's  default interface to  the system  (i.e., the  parts that
+  deal  with  memory  management   and  i/o  streams)  is  located  in
+  `src/base/ftsystem.c'.
+
+  The current  implementation uses standard C library  calls to manage
+  memory  and to read  font files.   It is  however possible  to write
+  custom implementations to suit specific systems.
+
+  To  tell the  GNU Make-based  build system  to use  a  custom system
+  interface, you have to  define the environment variable FTSYS_SRC to
+  point to the relevant implementation:
+
+    on Unix:
+
+      ./configure <your options>
+      export FTSYS_SRC=foo/my_ftsystem.c
+      make
+      make install
+
+    on Windows:
+
+      make setup <compiler>
+      set FTSYS_SRC=foo/my_ftsystem.c
+      make
+
+
+IV. Overriding default configuration and module headers
+
+  It  is possible  to override  the default  configuration  and module
+  headers without  changing the original files.  There  are three ways
+  to do that:
+
+
+  1. With GNU make
+
+    [This is actually a combination of method 2 and 3.]
+
+    Just put your custom `ftoption.h'  file into the objects directory
+    (normally `<topdir>/objs' if you build  in the source tree, or the
+    directory where  you invoke configure  if you build in  a separate
+    directory), which GNU make prefers over the standard location.  No
+    action  is  needed  for   `ftmodule.h'  because  it  is  generated
+    automatically in the objects directory.
+
+  2. Using the C include path
+
+    Use the  C include path  to ensure that  your own versions  of the
+    files are used at compile time when the lines
+
+      #include FT_CONFIG_OPTIONS_H
+      #include FT_CONFIG_MODULES_H
+
+    are      compiled.       Their      default      values      being
+    <freetype/config/ftoption.h> and <freetype/config/ftmodule.h>, you
+    can do something like:
+
+      custom/
+        config/
+          ftoption.h      => custom options header
+          ftmodule.h      => custom modules list
+
+      include/            => normal FreeType 2 include
+        ...
+
+    then change the C include path to always give the path to `custom'
+    before the FreeType 2 `include'.
+
+
+  3. Redefining FT_CONFIG_OPTIONS_H and FT_CONFIG_MODULES_H
+
+    Another way to do the same thing is to redefine the macros used to
+    name  the configuration  headers.  To  do  so, you  need a  custom
+    `ft2build.h' whose content can be as simple as:
+
+      #ifndef FT2_BUILD_MY_PLATFORM_H_
+      #define FT2_BUILD_MY_PLATFORM_H_
+
+      #define FT_CONFIG_OPTIONS_H  <custom/my-ftoption.h>
+      #define FT_CONFIG_MODULES_H  <custom/my-ftmodule.h>
+
+      #include <freetype/config/ftheader.h>
+
+      #endif /* FT2_BUILD_MY_PLATFORM_H_ */
+
+    Place those files in a separate directory, e.g.,
+
+      custom/
+        ft2build.h           => custom version described above
+        my-ftoption.h        => custom options header
+        my-ftmodule.h        => custom modules list header
+
+    and change  the C include path  to ensure that  `custom' is always
+    placed before the FT2 `include' during compilation.
+

+Debugging within the FreeType sources
+=====================================
+
+I. Configuration macros
+-----------------------
+
+There are  several ways to enable  debugging features in a  FreeType 2
+builds.  This is  controlled through the definition  of special macros
+located in the file `ftoptions.h'.  The macros are:
+
+
+  FT_DEBUG_LEVEL_ERROR
+
+    #define this macro if you want to compile the FT_ERROR macro calls
+    to print error  messages during program execution.   This will not
+    stop  the  program.  Very  useful  to  spot invalid  fonts  during
+    development and to code workarounds for them.
+
+  FT_DEBUG_LEVEL_TRACE
+
+    #define this macro if you want to compile both macros FT_ERROR and
+    FT_TRACE.  This  also includes the variants  FT_TRACE0, FT_TRACE1,
+    FT_TRACE2, ..., FT_TRACE7.
+
+    The  trace macros  are used  to  send debugging  messages when  an
+    appropriate  `debug level'  is configured  at runtime  through the
+    FT2_DEBUG environment variable (more on this later).
+
+  FT_DEBUG_MEMORY
+
+    If this  macro is #defined, the  FreeType engine is linked  with a
+    small  but  effective debugging  memory  manager  that tracks  all
+    allocations and frees that are performed within the font engine.
+
+    When  the  FT2_DEBUG_MEMORY  environment variable  is  defined  at
+    runtime, a  call to FT_Done_FreeType will  dump memory statistics,
+    including  the  list  of  leaked memory  blocks  with  the  source
+    locations where  these were allocated.   It is always a  very good
+    idea to define this in  development builds.  This works with _any_
+    program linked to FreeType, but requires a big deal of memory (the
+    debugging memory  manager never  frees the blocks  to the  heap in
+    order to detect double frees).
+
+    When  FT2_DEBUG_MEMORY isn't  defined  at  runtime, the  debugging
+    memory manager is ignored, and performance is unaffected.
+
+
+II. Debugging macros
+--------------------
+
+Several  macros  can be  used  within  the  FreeType sources  to  help
+debugging its code:
+
+
+  1. FT_ERROR(( ... ))
+
+    This macro is used to send debug messages that indicate relatively
+    serious errors  (like broken  font files), but  will not  stop the
+    execution of the running program.   Its code is compiled only when
+    either FT_DEBUG_LEVEL_ERROR or FT_DEBUG_LEVEL_TRACE are defined in
+    `ftoption.h'.
+
+    Note that you have to use a printf-like signature, but with double
+    parentheses, like in
+
+      FT_ERROR(( "your %s is not %s\n", "foo", "bar" ));
+
+
+  2. FT_ASSERT( condition )
+
+    This macro is used to check  strong assertions at runtime.  If its
+    condition isn't TRUE, the program will abort with a panic message.
+    Its  code   is  compiled   when  either   FT_DEBUG_LEVEL_ERROR  or
+    FT_DEBUG_LEVEL_TRACE   are  defined.    You   don't  need   double
+    parentheses here.  For example
+
+      FT_ASSERT( ptr != NULL );
+
+
+  3. FT_TRACE( level, (message...) )
+
+    The  FT_TRACE  macro is  used  to  send general-purpose  debugging
+    messages during program execution.   This macro uses an *implicit*
+    macro  named  FT_COMPONENT  used  to  name  the  current  FreeType
+    component being run.
+
+    The developer  should always  define FT_COMPONENT  as appropriate,
+    for example as in
+
+      #undef  FT_COMPONENT
+      #define FT_COMPONENT  trace_io
+
+    The  value  of the  FT_COMPONENT  macro  is an  enumeration  named
+    `trace_XXXX' where `XXXX' is one of the component names defined in
+    the internal  file `internal/fttrace.h'.   If you  modify FreeType
+    source and insert new `trace_XXXX'  macro, you must register it in
+    `fttrace.h'. If  you insert or  remove many trace macros,  you can
+    check   the    undefined   or   the   unused    trace   macro   by
+    `src/tools/chktrcmp.py'.
+
+    Each such component is assigned a `debug level', ranging from 0 to
+    7,  through   the  use  of  the   FT2_DEBUG  environment  variable
+    (described below) when a program linked with FreeType starts.
+
+    When FT_TRACE is  called, its level is compared to  the one of the
+    corresponding component.  Messages with trace levels *higher* than
+    the corresponding component level are filtered and never printed.
+
+    This means  that trace messages  with level 0 are  always printed,
+    those with  level 2 are only  printed when the component  level is
+    *at least* 2.
+
+    The  second parameter  to  FT_TRACE must  contain parentheses  and
+    correspond to a printf-like call, as in
+
+      FT_TRACE( 2, ( "your %s is not %s\n", "foo", "bar" ) )
+
+    The   shortcut  macros   FT_TRACE0,  FT_TRACE1,   FT_TRACE2,  ...,
+    FT_TRACE7 can  be used with  constant level indices, and  are much
+    cleaner to use, as in
+
+      FT_TRACE2(( "your %s is not %s\n", "foo", "bar" ));
+
+
+III. Environment variables
+--------------------------
+
+The  following  environment  variables control  debugging  output  and
+behaviour of FreeType at runtime.
+
+
+  FT2_DEBUG
+
+    This  variable   is  only  used   when  FreeType  is   built  with
+    FT_DEBUG_LEVEL_TRACE  defined.  It  contains a  list of  component
+    level definitions, following this format:
+
+      component1:level1 component2:level2 component3:level3 ...
+
+    where `componentX' is the name  of a tracing component, as defined
+    in `fttrace.h', but without the  `trace_' prefix.  `levelX' is the
+    corresponding level to use at runtime.
+
+    `any'  is a  special component  name that  will be  interpreted as
+    `any/all components'.  For example, the following definitions
+
+      set FT2_DEBUG=any:2 memory:5 io:4        (on Windows)
+      export FT2_DEBUG="any:2 memory:5 io:4"   (on Linux with bash)
+
+    both stipulate that all components should have level 2, except for
+    the memory and  io components which will be set  to trace levels 5
+    and 4, respectively.
+
+
+  FT2_DEBUG_MEMORY
+
+    This environment variable,  when defined, tells FreeType  to use a
+    debugging memory manager that will  track leaking memory blocks as
+    well as other common errors like double frees.  It is also capable
+    of  reporting _where_  the  leaking blocks  were allocated,  which
+    considerably  saves  time  when  debugging new  additions  to  the
+    library.
+
+    This  code  is only  compiled  when  FreeType  is built  with  the
+    FT_DEBUG_MEMORY macro #defined in  `ftoption.h' though, it will be
+    ignored in other builds.
+
+
+  FT2_ALLOC_TOTAL_MAX
+
+    This variable is  ignored if FT2_DEBUG_MEMORY is  not defined.  It
+    allows  you  to  specify  a  maximum  heap  size  for  all  memory
+    allocations performed  by FreeType.  This  is very useful  to test
+    the robustness  of the  font engine  and programs  that use  it in
+    tight memory conditions.
+
+    If it is undefined, or if its value is not strictly positive, then
+    no allocation bounds are checked at runtime.
+
+
+  FT2_ALLOC_COUNT_MAX
+
+    This variable is  ignored if FT2_DEBUG_MEMORY is  not defined.  It
+    allows  you to  specify  a maximum  number  of memory  allocations
+    performed    by    FreeType    before    returning    the    error
+    FT_Err_Out_Of_Memory.  This  is useful  for debugging  and testing
+    the engine's robustness.
+
+    If it is undefined, or if its value is not strictly positive, then
+    no allocation bounds are checked at runtime.

+Introduction
+============
+
+  The FreeType  Project is distributed in  several archive packages;
+  some of them may contain, in addition to the FreeType font engine,
+  various tools and  contributions which rely on, or  relate to, the
+  FreeType Project.
+
+  This  license applies  to all  files found  in such  packages, and
+  which do not  fall under their own explicit  license.  The license
+  affects  thus  the  FreeType   font  engine,  the  test  programs,
+  documentation and makefiles, at the very least.
+
+  This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
+  (Independent JPEG  Group) licenses, which  all encourage inclusion
+  and  use of  free  software in  commercial  and freeware  products
+  alike.  As a consequence, its main points are that:
+
+    o We don't promise that this software works. However, we will be
+      interested in any kind of bug reports. (`as is' distribution)
+
+    o You can  use this software for whatever you  want, in parts or
+      full form, without having to pay us. (`royalty-free' usage)
+
+    o You may not pretend that  you wrote this software.  If you use
+      it, or  only parts of it,  in a program,  you must acknowledge
+      somewhere  in  your  documentation  that  you  have  used  the
+      FreeType code. (`credits')
+
+  We  specifically  permit  and  encourage  the  inclusion  of  this
+  software, with  or without modifications,  in commercial products.
+  We  disclaim  all warranties  covering  The  FreeType Project  and
+  assume no liability related to The FreeType Project.
+
+
+  Finally,  many  people  asked  us  for  a  preferred  form  for  a
+  credit/disclaimer to use in compliance with this license.  We thus
+  encourage you to use the following text:

+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+There are  several ways  to build the  FreeType library,  depending on
+your system and the level of  customization you need.  Here is a short
+overview of the documentation available:
+
+
+I. Normal installation and upgrades
+===================================
+
+  1. Unix Systems (including Mac OS X, Cygwin, and MSys on Windows)
+
+    Please read `INSTALL.UNIX' to install or upgrade FreeType  2 on  a
+    Unix system.   Note  that  you  *need*  GNU  Make   for  automatic
+    compilation,  since other make tools won't work (this includes BSD
+    Make).
+
+    GNU Make VERSION 3.80 OR NEWER IS NEEDED!
+
+
+  2. On VMS with the `mms' build tool
+
+    See `INSTALL.VMS' for installation instructions on this platform.
+
+
+  3. Other systems using GNU Make
+
+    On non-Unix platforms,  it is possible to build  the library using
+    GNU Make  utility.  Note that  *NO OTHER MAKE TOOL  WILL WORK*[1]!
+    This  methods supports  several  compilers on  Windows, OS/2,  and
+    BeOS, including MinGW, Visual C++, Borland C++, and more.
+
+    Instructions are provided in the file `INSTALL.GNU'.
+
+
+  4. With an IDE Project File (e.g., for Visual Studio or CodeWarrior)
+
+    We provide a  small number of `project files'  for various IDEs to
+    automatically build  the library as  well.  Note that  these files
+    are  not supported  and only  sporadically maintained  by FreeType
+    developers, so don't expect them to work in each release.
+
+    To find them, have a  look at the content of the `builds/<system>'
+    directory, where <system> stands for your OS or environment.
+
+
+  5. Using cmake
+
+    See the top-level `CMakeLists.txt' file for more information.
+
+
+  6. From you own IDE, or own Makefiles
+
+    If  you  want  to  create   your  own  project  file,  follow  the
+    instructions   given  in  the   `INSTALL.ANY'  document   of  this
+    directory.
+
+
+II. Custom builds of the library
+================================
+
+  Customizing the compilation  of FreeType is easy, and  allows you to
+  select only the components of  the font engine that you really need.
+  For more details read the file `CUSTOMIZE'.
+
+
+----------------------------------------------------------------------
+
+[1] make++, a make tool written in Perl, has sufficient support of GNU
+    make extensions to build FreeType.  See
+
+      http://makepp.sourceforge.net
+
+    for more information; you need version 1.19 or newer, and you must
+    pass option `--norc-substitution'.

+Instructions on how to build FreeType with your own build tool
+==============================================================
+
+See  the  file `CUSTOMIZE'  to  learn  how  to customize  FreeType  to
+specific environments.
+
+
+I. Standard procedure
+---------------------
+
+  * DISABLE PRE-COMPILED  HEADERS!  This is very  important for Visual
+    C++, because FreeType uses lines like:
+
+      #include FT_FREETYPE_H
+
+    which are not correctly supported by this compiler while being ISO
+    C compliant!
+
+  * You need to add the directory `include' to your  include path when
+    compiling the library.
+
+  * FreeType 2 is made of  several components; each of them is located
+    in    a   subdirectory    of   `freetype2/src'.     For   example,
+    `freetype2/src/truetype/' contains the TrueType font driver.
+
+  * DO NOT COMPILE ALL C FILES!  Rather, compile the following ones.

+  of  the  drivers,  renderers,   and  optional  modules;  a  detailed
+  description of the various base  extension is given in the top-level
+  file `modules.cfg'.
+
+  You are done.  In case of problems, see the archives of the FreeType
+  development mailing list.
+
+
+II. Support for flat-directory compilation
+------------------------------------------
+
+  It is  possible to  put all  FreeType 2 source  files into  a single
+  directory, with the *exception* of the `include' hierarchy.
+
+  1. Copy all files in current directory
+
+      cp freetype2/src/base/*.[hc] .
+      cp freetype2/src/raster1/*.[hc] .
+      cp freetype2/src/smooth/*.[hc] .
+      etc.
+
+  2. Compile sources
+
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftsystem.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftinit.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftdebug.c
+      cc -c -Iinclude -DFT2_BUILD_LIBRARY ftbase.c
+      etc.
+
+    You don't  need to define  the FT_FLAT_COMPILATION macro  (as this
+    was required in previous releases of FreeType 2).

+This document contains instructions on how to cross-build the FreeType
+library on Unix systems, for example, building binaries for Linux/MIPS
+on  FreeBSD/i386.  Before  reading this  document, please  consult the
+file  `INSTALL.UNIX' for  required tools  and the  basic self-building
+procedure.
+
+
+  1. Required Tools
+  -----------------
+
+    For self-building the FreeType library  on a Unix system, GNU Make
+    3.80 or newer  is required.  `INSTALL.UNIX' contains  hints how to
+    check the installed `make'.
+
+    The GNU C  compiler to cross-build the target  system is required.
+    Currently, using a non-GNU cross  compiler is untested.  The cross
+    compiler is  expected to be  installed with a system  prefix.  For
+    example, if  your building system  is FreeBSD/i386 and  the target
+    system is Linux/MIPS, the cross  compiler should be installed with
+    the name `mips-ip22-linuxelf-gcc'.
+
+    A C  compiler for a self-build  is required also, to  build a tool
+    (`apinames') that is executed during the build procedure.  Non-GNU
+    self compilers are acceptable, but such a setup is untested.
+
+
+  2. Configuration
+  ----------------
+
+    2.1. Building and target system
+
+      To configure  a cross-build,  the options  `--host=<system>' and
+      `--build=<system>'  must be  passed to  the `configure'  script.
+      For example, if your build system is FreeBSD/i386 and the target
+      system is Linux/MIPS, say
+
+        ./configure \
+          --build=i386-unknown-freebsd \
+          --host=mips-ip22-linuxelf \
+          [other options]
+
+      It should  be noted that `--host=<system>'  specifies the system
+      where the built binaries will  be executed, not the system where
+      the build actually happens.   Older versions of GNU autoconf use
+      the option  pair `--host=' and `--target='.  This  is broken and
+      doesn't work.  Similarly, an explicit CC specification like
+
+        env CC=mips-ip22-linux-gcc ./configure                 # BAD
+
+      or
+
+        env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure  # BAD
+
+      doesn't   work  either;  such   a  configuration   confuses  the
+      `configure' script while  trying to find the cross  and native C
+      compilers.
+
+
+    2.2. The prefix to install FreeType2
+
+      Setting `--prefix=<prefix>'  properly is important.   The prefix
+      to  install  FreeType2  is written  into  the  `freetype-config'
+      script and `freetype2.pc' configuration file.
+
+      If  the built  FreeType  2 library  is  used as  a  part of  the
+      cross-building system,  the prefix  is expected to  be different
+      from  the self-building  system.  For  example, a  configuration
+      with   `--prefix=/usr/local'   installs    binaries   into   the
+      system-wide `/usr/local' directory, which then can't be executed
+      due  to the  incorrect architecture.   This causes  confusion in
+      configuration of all applications  that use FreeType2.  Instead,
+      use a prefix  to install the cross-build into  a separate system
+      tree, for example, `--prefix=/usr/local/mips-ip22-linux/'.
+
+      On the other hand, if the built  FreeType 2 library is used as a
+      part of the target system,  the prefix to install should reflect
+      the file system structure of the target system.
+
+
+    2.3. Library dependencies
+
+      FreeType normally depends on external libraries like `libpng' or
+      `libharfbuzz'.   The  easiest case  is  to  deactivate all  such
+      dependencies  using the  `--without-XXX' configuration  options.
+      However, if you  want to use those libraries,  you should ensure
+      that  they  are available  both  on  the  target system  and  as
+      (cross-compiled) libraries on the build system.
+
+      FreeType uses  `pkg-config' to find  most of the  libraries; the
+      other libraries it links to  are expected in the standard system
+      directories.   Since the  default pkg-config's  meta-information
+      files (like `harfbuzz.pc') of the build platform don't work, use
+      one of the two possible solutions below.
+
+        o Use pkg-config's meta-information files that are adjusted to
+          cross-compile  and  cross-link  with the  target  platform's
+          libraries.  Make sure those files are found before the build
+          system's default files.  Example:
+
+            ./configure \
+              --build=i386-unknown-freebsd \
+              --host=mips-ip22-linuxelf \
+              PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
+              [other options]
+
+          See the manpage of `pkg-config' for more details.
+
+        o Set variables like LIBPNG_LIBS  as additional options to the
+          `configure' script, overriding the values `pkg-config' would
+          provide.  `configure --help' shows the available environment
+          variables.  Example:
+
+            ./configure \
+              --build=i386-unknown-freebsd \
+              --host=mips-ip22-linuxelf \
+              LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
+              LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
+              [other options]
+
+
+  3. Building command
+  -------------------
+
+    If  the  configuration  finishes successfully,  invoking  GNU make
+    builds FreeType2.  Just say
+
+      make
+
+    or
+
+      gmake
+
+    depending on the name the GNU make binary actually has.
+
+
+  4. Installation
+  ---------------
+
+    Saying
+
+      make install
+
+    as usual to install FreeType2 into the directory tree specified by
+    the argument of the `--prefix' option.
+
+    As noted in section 2.2,  FreeType2  is sometimes configured to be
+    installed  into the  system directory  of the  target  system, and
+    should  not be installed  in the  cross-building system.   In such
+    cases, the  make variable `DESTDIR'  is useful to change  the root
+    directory in the installation.  For example, after
+
+      make DESTDIR=/mnt/target_system_root/ install
+
+    the built FreeType2 library files are installed into the directory
+    `/mnt/target_system_root/<prefix_in_configure>/lib'.
+
+
+  5. TODO
+  -------
+
+    Cross building between Cygwin (or MSys) and Unix must be tested.

+This document contains instructions how  to build the FreeType library
+on non-Unix systems with  the help of GNU Make.  Note  that if you are
+running  Cygwin  or  MinGW/MSYS  in Windows,  you  should  follow  the
+instructions in the file `INSTALL.UNIX' instead.
+
+
+  FreeType 2 includes a powerful and flexible build system that allows
+  you to  easily compile it on  a great variety of  platforms from the
+  command line.  To do so, just follow these simple instructions.
+
+  1. Install GNU Make
+  -------------------
+
+    Because  GNU Make  is  the  only Make  tool  supported to  compile
+    FreeType 2, you should install it on your machine.
+
+    The FreeType 2 build system relies on many features special to GNU
+    Make.
+
+    NEARLY ALL OTHER MAKE TOOLS  FAIL, INCLUDING `BSD MAKE', SO REALLY
+    INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
+
+    Note that  make++, a  make tool written  in Perl,  supports enough
+    features of GNU make to compile FreeType.  See
+
+      http://makepp.sourceforge.net
+
+    for more information; you need version 1.19 or newer, and you must
+    pass option `--norc-substitution'.
+
+    Make sure that you are invoking GNU Make from the command line, by
+    typing something like:
+
+      make -v
+
+    to display its version number.
+
+    VERSION 3.80 OR NEWER IS NEEDED!
+
+
+  2. Invoke `make'
+  ----------------
+
+    Go to  the root  directory of FreeType  2, then simply  invoke GNU
+    Make from the command line.   This will launch the FreeType 2 host
+    platform  detection routines.   A summary  will be  displayed, for
+    example, on Win32.
+
+
+      ==============================================================
+      FreeType build system -- automatic system detection
+
+      The following settings are used:
+
+        platform                     windows
+        compiler                     gcc
+        configuration directory      .\builds\windows
+        configuration rules          .\builds\windows\w32-gcc.mk
+
+      If this does not correspond to your system or settings please
+      remove the file 'config.mk' from this directory then read the
+      INSTALL file for help.
+
+      Otherwise, simply type 'make' again to build the library
+      or 'make refdoc' to build the API reference (the latter needs
+      python).
+      =============================================================
+
+
+    If the detected settings correspond to your platform and compiler,
+    skip to step 5.  Note that if your platform is completely alien to
+    the build system, the detected platform will be `ansi'.
+
+
+  3. Configure the build system for a different compiler
+  ------------------------------------------------------
+
+    If the build system correctly detected your platform, but you want
+    to use a different compiler  than the one specified in the summary
+    (for most platforms, gcc is the default compiler), invoke GNU Make
+    with
+
+      make setup <compiler>
+
+    Examples:
+
+      to use Visual C++ on Win32, type:  `make setup visualc'
+      to use Borland C++ on Win32, type  `make setup bcc32'
+      to use Watcom C++ on Win32, type   `make setup watcom'
+      to use Intel C++ on Win32, type    `make setup intelc'
+      to use LCC-Win32 on Win32, type:   `make setup lcc'
+      to use Watcom C++ on OS/2, type    `make setup watcom'
+      to use VisualAge C++ on OS/2, type `make setup visualage'
+
+    The  <compiler> name to  use is  platform-dependent.  The  list of
+    available  compilers for  your  system is  available  in the  file
+    `builds/<system>/detect.mk'.
+
+    If you  are satisfied  by the new  configuration summary,  skip to
+    step 5.
+
+
+  4. Configure the build system for an unknown platform/compiler
+  --------------------------------------------------------------
+
+    The auto-detection/setup  phase of the build system  copies a file
+    to the current directory under the name `config.mk'.
+
+    For    example,    on    OS/2+gcc,    it   would    simply    copy
+    `builds/os2/os2-gcc.mk' to `./config.mk'.
+
+    If for  some reason your  platform isn't correctly  detected, copy
+    manually the configuration sub-makefile to `./config.mk' and go to
+    step 5.
+
+    Note  that  this file  is  a  sub-Makefile  used to  specify  Make
+    variables  for compiler  and linker  invocation during  the build.
+    You can  easily create your own  version from one  of the existing
+    configuration files,  then copy it to the  current directory under
+    the name `./config.mk'.
+
+
+  5. Build the library
+  --------------------
+
+    The auto-detection/setup  phase should have  copied a file  in the
+    current  directory,  called  `./config.mk'.   This  file  contains
+    definitions of various Make  variables used to invoke the compiler
+    and linker during the build.  [It has also generated a file called
+    `ftmodule.h'   in  the  objects   directory  (which   is  normally
+    `<toplevel>/objs/');  please read  the  file `docs/CUSTOMIZE'  for
+    customization of FreeType.]
+
+    To  launch  the build,  simply  invoke  GNU  Make again:  The  top
+    Makefile will detect the configuration file and run the build with
+    it.
+
+
+  Final note
+
+    The above instructions build a  _statically_ linked library of the
+    font engine in the `objs' directory.   On Windows, you can build a
+    DLL  either  with  MinGW  (within an  MSYS  shell,  following  the
+    instructions in `INSTALL.UNIX'), or you  use one of the Visual C++
+    project files; see  the  subdirectories  of `builds/windows'.  For
+    everything else,  you are on  your own,  and you might  follow the
+    instructions in `INSTALL.ANY' to create your own Makefiles.

+Please follow the instructions  in INSTALL.UNIX to install FreeType on

+
+Currently FreeType2 functions based on some deprecated Carbon APIs
+return FT_Err_Unimplemented_Feature always, even if FreeType2 is
+configured and built on the system that deprecated Carbon APIs are
+available. To enable deprecated FreeType2 functions as far as possible,

+
+Starting with Mac OS X 10.5, gcc defaults the deployment target
+to 10.5. In previous versions of Mac OS X, this defaulted to 10.1.
+If you want your built binaries to run only on 10.5, this change
+does not concern you.  If you want them to also run on older versions
+of Mac OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET
+environment variable or pass -mmacosx-version-min to gcc. You should
+specify the oldest version of Mac OS you want the code to run on.
+For example, if you use Bourne shell:
+
+	export MACOSX_DEPLOYMENT_TARGET=10.2
+
+or, if you use C shell:
+
+	setenv MACOSX_DEPLOYMENT_TARGET 10.2
+
+Alternatively, you could pass "-mmacosx-version-min=10.2" to gcc.
+
+Here the number 10.2 is the lowest version that the built binaries
+can run on. In the cases in above, the built binaries will run on
+Mac OS X 10.2 and later, but _not_ earlier. If you want to run on
+earlier, you have to set lower version, e.g. 10.0.
+
+For classic Mac OS (Mac OS 7, 8, 9) please refer to builds/mac/README.

+This  document contains  instructions  on how  to  build the  FreeType
+library on Unix  systems.  This also works for  emulations like Cygwin
+or MSys on Win32:
+
+
+  1. Ensure that you are using GNU Make
+  -------------------------------------
+
+    The FreeType build system  _exclusively_ works with GNU Make.  You
+    will  not be  able to  compile the  library with  the instructions
+    below using any other alternative (including BSD Make).
+
+    Check that you have GNU make by running the command:
+
+       make -v
+
+    This should dump some text that begins with:
+
+       GNU Make  <version number>
+       Copyright (C) <year> Free Software Foundation Inc.
+
+    Note that version  3.80 or higher is *required* or the  build will
+    fail.
+
+    It is also fine to have GNU Make under another name (e.g. 'gmake')
+    if you use the MAKE variable as described below.
+
+    As  a  special exception,  'makepp'  can  also  be used  to  build
+    FreeType 2.  See the file docs/MAKEPP for details.
+
+
+  2. Regenerate the configure script if needed
+  --------------------------------------------
+
+    This only applies if you  are building a git snapshot or checkout,
+    *not* if you grabbed the sources of an official release.
+
+    You  need  to invoke  the  `autogen.sh'  script  in the  top-level
+    directory  in order  to  create the  `configure'  script for  your
+    platform.  Normally, this simply means typing:
+
+      sh autogen.sh
+
+    In case of problems, you  may need to install or upgrade Automake,
+    Autoconf or  Libtool.  See  README.git in the  top-level directory
+    for more information.
+
+
+  3. Build and install the library
+  --------------------------------
+
+    The following  should work  on all Unix  systems where  the `make'
+    command invokes GNU Make:
+
+      ./configure [options]
+      make
+      make install           (as root)
+
+    The default installation path  is `/usr/local'.  It can be changed
+    with the `--prefix=<path>' option.  Example:
+
+      ./configure --prefix=/usr
+
+    When using  a different command  to invoke GNU Make,  use the MAKE
+    variable.  For example,  if `gmake' is the command  to use on your
+    system, do something like:
+
+       MAKE=gmake ./configure [options]
+       gmake
+       gmake install            (as root)
+
+    If  this still doesn't  work, there  must be  a problem  with your
+    system (e.g., you are using a very old version of GNU Make).
+
+    It  is possible  to  compile FreeType  in  a different  directory.
+    Assuming the FreeType source  files in directory `/src/freetype' a
+    compilation in directory `foo' works as follows:
+
+      cd foo
+      /src/freetype/configure [options]
+      make
+      make install
+
+
+  3.1 Interdependency with HarfBuzz
+  .................................
+
+    Note that there  is a chicken-and-egg problem  currently since the
+    HarfBuzz library  (used by the  auto-hinter to improve  support of
+    OpenType  fonts)  depends on  FreeType,  which  can be  solved  as
+    follows in case HarfBuzz is not yet installed on your system.
+
+    1. Call    FreeType's     `configure'    script     with    option
+       `--without-harfbuzz', then compile and install FreeType.
+
+    2. Compile and install HarfBuzz.
+
+    3. Call    FreeType's    `configure'   script    without    option
+       `--without-harfbuzz' (after  executing `make  distclean'), then
+       compile and install FreeType again.

+
+It is actually very  straightforward to install the Freetype2 library.
+Just  execute vms_make.com from  the toplevel  directory to  build the
+library.  This procedure currently accepts the following options:
+
+DEBUG
+  Build the library with debug information and without optimization.
+
+lopts=<value>
+  Options to pass to the link command e.g. lopts=/traceback

+In case you did download the demos, place them in a separate directory
+sharing the same toplevel as the directory of Freetype2 and follow the
+same  instructions as  above  for  the demos  from  there.  The  build
+process relies on this to figure the location of the Freetype2 include
+files.
+
+
+To rebuild  the  sources it is necessary to  have MMS/MMK installed on
+the system.
+
+The library is available in the directory
+
+  [.LIB]
+
+To  compile applications  using  FreeType  2 you  have  to define  the
+logical FREETYPE pointing to the directory
+
+  [.INCLUDE.FREETYPE]
+
+i.e., if  the directory in which  this INSTALL.VMS file  is located is
+$disk:[freetype] then define the logical with
+
+  define freetype $disk:[freetype.include.freetype]
+
+This version has  been tested with Compaq C  V6.2-006 on OpenVMS Alpha
+V7.2-1.

+
+The  FreeType 2  font  engine is  copyrighted  work and  cannot be  used
+legally  without a  software license.   In  order to  make this  project
+usable  to a vast  majority of  developers, we  distribute it  under two
+mutually exclusive open-source licenses.
+
+This means  that *you* must choose  *one* of the  two licenses described
+below, then obey  all its terms and conditions when  using FreeType 2 in
+any of your projects or products.
+
+  - The FreeType License, found in  the file `FTL.TXT', which is similar
+    to the original BSD license *with* an advertising clause that forces
+    you  to  explicitly cite  the  FreeType  project  in your  product's
+    documentation.  All  details are in the license  file.  This license
+    is  suited  to products  which  don't  use  the GNU  General  Public
+    License.
+
+    Note that  this license  is  compatible  to the  GNU General  Public
+    License version 3, but not version 2.
+
+  - The GNU General Public License version 2, found in  `GPLv2.TXT' (any
+    later version can be used  also), for programs which already use the
+    GPL.  Note  that the  FTL is  incompatible  with  GPLv2 due  to  its
+    advertisement clause.
+
+The contributed BDF and PCF drivers  come with a license similar to that
+of the X Window System.  It is compatible to the above two licenses (see
+file src/bdf/README and  src/pcf/README).  The same holds  for the files
+`fthash.c' and  `fthash.h'; their  code was  part of  the BDF  driver in
+earlier FreeType versions.
+
+The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
+compatible to the above two licenses.
+
+The MD5 checksum support (only used for debugging in development builds)
+is in the public domain.

+This  file describes various  problems that  have been  encountered in
+compiling,  installing  and   running  FreeType  2.   Suggestions  for
+additions or other improvements to this file are welcome.
+
+----------------------------------------------------------------------
+
+Running Problems
+================
+
+
+* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
+  handled correctly.
+
+-----
+
+Of course,  there might be  bugs in FreeType,  but some fonts based on
+the  PostScript  format can't  be handled indeed.  The reason  is that
+FreeType  doesn't contain a full  PostScript  interpreter  but applies
+pattern matching instead.  In case a font doesn't follow the  standard
+structure of the given font format, FreeType fails.  A typical example
+is Adobe's `Optima'  font family which  contains extra code  to switch
+between low and high resolution versions of the glyphs.
+
+It might be  possible to patch  FreeType in  some situations,  though.
+Please report failing fonts so that we investigate the problem and set
+up a list of such problematic fonts.
+
+
+* Why do identical FreeType  versions render differently  on different
+  platforms?
+
+-----
+
+Different distributions compile FreeType with different options.   The
+developer  version of  a  distribution's  FreeType  package,  which is
+needed to compile  your program  against FreeType,  includes the  file
+ftoption.h.  Compare  each platform's  copy of ftoption.h to  find the
+differences.
+
+
+----------------------------------------------------------------------
+
+
+Compilation Problems
+====================
+
+
+* I get an `internal compilation error' (ICE) while compiling FreeType
+  2.2.1 with Intel C++.
+
+  This has been reported for the following compiler version:
+
+    Intel(R) C++ Compiler for 32-bit applications,
+      Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
+
+-----
+
+The best solution is to update the compiler to version
+
+  Intel(R) C++ Compiler for 32-bit applications,
+    Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
+
+or newer.  If this isn't feasible, apply the following patch.

+Due  to our  use of  `libtool' to  generate and  install the  FreeType 2
+libraries on  Unix systems, as  well as  other historical events,  it is
+generally very  difficult to  know precisely which  release of  the font
+engine is installed on a given system.
+
+This file tries  to explain why and to document  ways to properly detect
+FreeType on Unix.
+
+
+1. Version and Release numbers
+------------------------------
+
+For each new  public release of FreeType 2, there  are generally *three*
+distinct `version' numbers to consider:
+
+  * The official FreeType 2 release number, like 2.3.1 or 2.4.10.
+
+  * The libtool (and  Unix) specific version number,  like 13.0.7.  This
+    is what `freetype-config --version' returns.
+
+  * The platform-specific  shared object  number, used for  example when
+    the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
+
+The platform-specific  number is, unsurprisingly,  platform-specific and
+varies  with the  operating system  you are  using (several  variants of
+Linux, FreeBSD,  Solaris, etc.).  You  should thus _never_ use  it, even
+for simple tests.
+
+The libtool-specific  number does  not equal the  release number  but is
+tied to it.
+
+The release number is available  at *compile* time through the following
+macros defined in FT_FREETYPE_H:
+
+  - FREETYPE_MAJOR: major release number
+  - FREETYPE_MINOR: minor release number
+  - FREETYPE_PATCH: patch release number
+
+See below for a small autoconf fragment.
+
+The  release  number   is  also  available  at   *runtime*  through  the
+`FT_Library_Version' API.
+
+
+2. History
+----------
+
+The  following   table  gives,  for   all  releases  since   2.4.0,  the
+corresponding libtool number, as well  as the shared object number found
+on _most_ systems, but not all of them:

+This  file contains  a list  of various  font formats.   It gives  the
+reference document and whether it is supported in FreeType 2.
+
+Table fields
+------------
+
+  wrapper format
+    The format used to represent the font data.  In the table below it
+    is  used only  if the  font format  differs.  Possible  values are
+    `SFNT' (binary), `PS'  (a text header, followed by  binary or text
+    data), `LZW'  (compressed with  either `gzip' or  `compress'), and
+    `BZ2' (compressed with `bzip2`).
+
+  font format
+    How the font is to be accessed, possibly after converting the file
+    type and wrapper  format into a generic form.   Bitmap formats are
+    `BDF',  `PCF', and  one form  of `WINFNT';  all others  are vector
+    formats.   `PS' indicates  third-order,  `TT' second-order  Bézier
+    curves.
+
+  font type
+    Sub-formats of the  font format.  `SBIT' and  `MACSBIT' are bitmap
+    formats,  `MM' and  `VAR' support  optical axes.   `CFF2' supports
+    optical axes also.
+
+  glyph access
+    If  not specified,  the glyph  access  is `standard'  to the  font
+    format.   Values are  `CID' for  CID-keyed fonts,  `SYNTHETIC' for
+    fonts that  are modified  versions of  other fonts  by means  of a
+    transformation matrix, and  `TYPE_0' for PS fonts which  are to be
+    accessed in a tree-like structure.
+
+  FreeType driver
+    The module in the FreeType library which handles the specific font
+    format.  A missing  entry means that FreeType  doesn't support the
+    font format (yet).
+
+
+Notes
+-----
+
+  The  SFNT  container  format also  provides  `collections'  (usually
+  having the file extension `.ttc'  or `.otc').  A collection contains
+  multiple font faces that share some tables to avoid redundancy, thus
+  reducing the file  size.  In FreeType, elements of  a collection can
+  be accessed with a proper face index.
+
+  Both  the GX  and the  OpenType 1.8  variation fonts  provide `named
+  instances'.  FreeType  maps them to  face indices (they can  also be
+  accessed with the standard MM interface).
+
+  Other  font  formats  (not  using the  SFNT  wrapper)  also  provide
+  multiple faces  within one  file; they are  marked with  an asterisk
+  (`*') in the table below.
+
+  FreeType can  be configured to  support Mac  files (on older  Mac OS
+  versions, a `file' is stored as a data and a resource fork, this is,
+  within two  separate data chunks).  If  a file can't be  opened as a
+  font, FreeType then checks whether it  is a resource fork, trying to
+  extract  the contained  font data  from  either a  `POST' or  `sfnt'
+  resource.
+
+
+Please  send additions  and/or  corrections to  wl@gnu.org  or to  the
+FreeType   developer's   list    at   freetype-devel@nongnu.org   (for
+subscribers only).   If you can  provide a  font example for  a format
+which isn't supported yet please send a mail too.

+.
+.SH DESCRIPTION
+.
+.B freetype-config
+returns information needed for compiling and linking programs with the

+There are two types of options: output/display selection options, and
+path override options.
+.
+.
+.SS Output selection options
+.
+Only one of the output selection options should be given at each program
+invocation.
+.
+.TP
+.B \-\-prefix
+Return the prefix value of the installed FreeType library (the default
+prefix will be `/usr' in most cases for distribution-installed
+packages).
+.
+.TP
+.B \-\-exec-prefix
+Return the executable prefix value of the installed FreeType library

+I. Introduction
+===============
+
+  A  rasterizer is  a library  in charge  of converting  a vectorial
+  representation of a shape  into a bitmap.  The FreeType rasterizer
+  has  been  originally developed  to  render  the  glyphs found  in
+  TrueType  files, made  up  of segments  and second-order  Béziers.
+  Meanwhile it has been extended to render third-order Bézier curves
+  also.   This  document  is   an  explanation  of  its  design  and
+  implementation.
+
+  While  these explanations start  from the  basics, a  knowledge of
+  common rasterization techniques is assumed.
+
+
+II. Rendering Technology
+========================
+
+1. Requirements
+---------------
+
+  We  assume that  all scaling,  rotating, hinting,  etc.,  has been
+  already done.  The glyph is thus  described by a list of points in
+  the device space.
+
+  - All point coordinates  are in the 26.6 fixed  float format.  The
+    used orientation is:
+
+
+       ^ y
+       |         reference orientation
+       |
+       *----> x
+      0
+
+
+    `26.6' means  that 26 bits  are used for  the integer part  of a
+    value   and  6   bits  are   used  for   the   fractional  part.
+    Consequently, the `distance'  between two neighbouring pixels is
+    64 `units' (1 unit = 1/64th of a pixel).
+
+    Note  that, for  the rasterizer,  pixel centers  are  located at
+    integer   coordinates.   The   TrueType   bytecode  interpreter,
+    however, assumes that  the lower left edge of  a pixel (which is
+    taken  to be  a square  with  a length  of 1  unit) has  integer
+    coordinates.
+
+
+        ^ y                                        ^ y

+
+   TrueType bytecode interpreter          FreeType rasterizer
+
+
+    A pixel line in the target bitmap is called a `scanline'.
+
+  - A  glyph  is  usually  made  of several  contours,  also  called
+    `outlines'.  A contour is simply a closed curve that delimits an
+    outer or inner region of the glyph.  It is described by a series
+    of successive points of the points table.
+
+    Each point  of the glyph  has an associated flag  that indicates
+    whether  it is  `on' or  `off' the  curve.  Two  successive `on'
+    points indicate a line segment joining the two points.
+
+    One `off' point amidst two `on' points indicates a second-degree
+    (conic)  Bézier parametric  arc, defined  by these  three points
+    (the `off' point being the  control point, and the `on' ones the
+    start and end points).  Similarly, a third-degree (cubic) Bézier
+    curve  is described  by four  points (two  `off'  control points
+    between two `on' points).
+
+    Finally,  for  second-order curves  only,  two successive  `off'
+    points  forces the  rasterizer to  create, during  rendering, an
+    `on'  point amidst them,  at their  exact middle.   This greatly
+    facilitates the  definition of  successive Bézier arcs.
+
+  The parametric form of a second-order Bézier curve is:
+
+      P(t) = (1-t)^2*P1 + 2*t*(1-t)*P2 + t^2*P3
+
+      (P1 and P3 are the end points, P2 the control point.)
+
+  The parametric form of a third-order Bézier curve is:
+
+      P(t) = (1-t)^3*P1 + 3*t*(1-t)^2*P2 + 3*t^2*(1-t)*P3 + t^3*P4
+
+      (P1 and P4 are the end points, P2 and P3 the control points.)
+
+  For both formulae, t is a real number in the range [0..1].
+
+  Note  that the rasterizer  does not  use these  formulae directly.
+  They exhibit,  however, one very  useful property of  Bézier arcs:
+  Each  point of  the curve  is a  weighted average  of  the control
+  points.
+
+  As all weights  are positive and always sum up  to 1, whatever the
+  value  of t,  each arc  point lies  within the  triangle (polygon)
+  defined by the arc's three (four) control points.
+
+  In  the following,  only second-order  curves are  discussed since
+  rasterization of third-order curves is completely identical.
+
+  Here some samples for second-order curves.
+
+
+                                        *            # on curve
+                                                     * off curve

+         Two `on' points       and one `off' point
+                                  between them
+
+                      *

+         \          -  -     points between them. The point
+          \        /    \    marked `0' is the middle of the
+           -      0      \   `off' points, and is a `virtual
+            -_  _-       #   on' point where the curve passes.
+              --             It does not appear in the point
+              *              list.
+
+
+2. Profiles and Spans
+---------------------
+
+  The following is a basic explanation of the _kind_ of computations
+  made  by  the   rasterizer  to  build  a  bitmap   from  a  vector
+  representation.  Note  that the actual  implementation is slightly
+  different, due to performance tuning and other factors.
+
+  However, the following ideas remain  in the same category, and are
+  more convenient to understand.
+
+
+  a. Sweeping the Shape
+
+    The best way to fill a shape is to decompose it into a number of
+    simple  horizontal segments,  then turn  them on  in  the target
+    bitmap.  These segments are called `spans'.
+
+                __---__
+             _--       -_
+           _-            -
+          -               \
+         /                 \
+        /                   \
+       |                     \
+
+                __---__         Example: filling a shape
+             _----------_                with spans.
+           _--------------
+          ----------------\
+         /-----------------\    This is typically done from the top
+        /                   \   to the bottom of the shape, in a
+       |           |         \  movement called a `sweep'.
+                   V
+
+                __---__
+             _----------_

+          ----------------\
+         /-----------------\
+        /-------------------\
+       |---------------------\
+
+
+    In  order  to draw  a  span,  the  rasterizer must  compute  its
+    coordinates, which  are simply the x coordinates  of the shape's
+    contours, taken on the y scanlines.

+                   /---/    |---|
+                  /---/     |---|  And then turn on the spans a-b
+                 /---/      |---|  and c-d.

+
+
+  b. Decomposing Outlines into Profiles
+
+    For  each  scanline during  the  sweep,  we  need the  following
+    information:
+
+    o The  number of  spans on  the current  scanline, given  by the
+      number of  shape points  intersecting the scanline  (these are
+      the points a, b, c, and d in the above example).
+
+    o The x coordinates of these points.
+
+    x coordinates are  computed before the sweep, in  a phase called
+    `decomposition' which converts the glyph into *profiles*.
+
+    Put it simply, a `profile'  is a contour's portion that can only
+    be either ascending or descending,  i.e., it is monotonic in the
+    vertical direction (we also say  y-monotonic).  There is no such
+    thing as a horizontal profile, as we shall see.
+
+    Here are a few examples:
+
+
+      this square
+                                          1         2

+      A more general contour can be made of more than two profiles:
+
+              __     ^
+             /  |   /  ___          /    |
+            /   |     /   |        /     |       /     |

+
+                <--               up              down
+
+
+    Successive  profiles are  always joined  by  horizontal segments
+    that are not part of the profiles themselves.
+
+    For  the  rasterizer,  a  profile  is  simply  an  *array*  that
+    associates  one  horizontal *pixel*  coordinate  to each  bitmap
+    *scanline*  crossed  by  the  contour's section  containing  the
+    profile.  Note that profiles are *oriented* up or down along the
+    glyph's original flow orientation.
+
+    In other graphics libraries, profiles are also called `edges' or
+    `edgelists'.
+
+
+  c. The Render Pool
+
+    FreeType  has been designed  to be  able to  run well  on _very_
+    light systems, including embedded systems with very few memory.
+
+    A render pool  will be allocated once; the  rasterizer uses this
+    pool for all  its needs by managing this  memory directly in it.
+    The  algorithms that are  used for  profile computation  make it
+    possible to use  the pool as a simple  growing heap.  This means
+    that this  memory management is  actually quite easy  and faster
+    than any kind of malloc()/free() combination.
+
+    Moreover,  we'll see  later that  the rasterizer  is  able, when
+    dealing with profiles too large  and numerous to lie all at once
+    in  the render  pool, to  immediately decompose  recursively the
+    rendering process  into independent sub-tasks,  each taking less
+    memory to be performed (see `sub-banding' below).
+
+    The  render pool doesn't  need to  be large.   A 4KByte  pool is
+    enough for nearly all renditions, though nearly 100% slower than
+    a more comfortable 16KByte or 32KByte pool (that was tested with
+    complex glyphs at sizes over 500 pixels).
+
+
+  d. Computing Profiles Extents
+
+    Remember that a profile is an array, associating a _scanline_ to
+    the x pixel coordinate of its intersection with a contour.
+
+    Though it's not exactly how the FreeType rasterizer works, it is
+    convenient  to think  that  we need  a  profile's height  before
+    allocating it in the pool and computing its coordinates.
+
+    The profile's height  is the number of scanlines  crossed by the
+    y-monotonic section of a contour.  We thus need to compute these
+    sections from  the vectorial description.  In order  to do that,
+    we are  obliged to compute all  (local and global)  y extrema of
+    the glyph (minima and maxima).
+
+
+           P2             For instance, this triangle has only
+                          two y-extrema, which are simply
+           |\
+           | \               P2.y  as a vertical maximum
+          |   \              P3.y  as a vertical minimum
+          |    \
+         |      \            P1.y is not a vertical extremum (though
+         |       \           it is a horizontal minimum, which we
+      P1 ---___   \          don't need).
+               ---_\
+                     P3
+
+
+    Note  that the  extrema are  expressed  in pixel  units, not  in
+    scanlines.   The triangle's  height  is certainly  (P3.y-P2.y+1)
+    pixel  units,   but  its  profiles'  heights   are  computed  in
+    scanlines.  The exact conversion is simple:
+
+      - min scanline = FLOOR  ( min y )
+      - max scanline = CEILING( max y )
+
+    A problem  arises with Bézier  Arcs.  While a segment  is always
+    necessarily y-monotonic (i.e.,  flat, ascending, or descending),
+    which makes extrema computations easy,  the ascent of an arc can
+    vary between its control points.
+
+
+                          P2
+                         *
+                                       # on curve
+                                       * off curve
+                   __-x--_
+                _--       -_
+          P1  _-            -          A non y-monotonic Bézier arc.
+             #               \
+                              -        The arc goes from P1 to P3.
+                               \
+                                \  P3
+                                 #
+
+
+    We first  need to be  able to easily detect  non-monotonic arcs,
+    according to  their control points.  I will  state here, without
+    proof, that the monotony condition can be expressed as:
+
+      P1.y <= P2.y <= P3.y   for an ever-ascending arc
+
+      P1.y >= P2.y >= P3.y   for an ever-descending arc
+
+    with the special case of
+
+      P1.y = P2.y = P3.y     where the arc is said to be `flat'.
+
+    As  you can  see, these  conditions can  be very  easily tested.
+    They are, however, extremely important, as any arc that does not
+    satisfy them necessarily contains an extremum.
+
+    Note  also that  a monotonic  arc can  contain an  extremum too,
+    which is then one of its `on' points:
+
+
+        P1           P2
+          #---__   *         P1P2P3 is ever-descending, but P1
+                -_           is an y-extremum.
+                  -
+           ---_    \
+               ->   \
+                     \  P3
+                      #
+
+
+    Let's go back to our previous example:
+
+
+                          P2
+                         *
+                                       # on curve
+                                       * off curve
+                   __-x--_
+                _--       -_
+          P1  _-            -          A non-y-monotonic Bézier arc.
+             #               \
+                              -        Here we have
+                               \              P2.y >= P1.y &&
+                                \  P3         P2.y >= P3.y      (!)
+                                 #
+
+
+    We need to  compute the vertical maximum of this  arc to be able
+    to compute a profile's height (the point marked by an `x').  The
+    arc's equation indicates that  a direct computation is possible,
+    but  we rely  on a  different technique,  which use  will become
+    apparent soon.
+
+    Bézier  arcs have  the  special property  of  being very  easily
+    decomposed into two sub-arcs,  which are themselves Bézier arcs.
+    Moreover, it is easy to prove that there is at most one vertical
+    extremum on  each Bézier arc (for  second-degree curves; similar
+    conditions can be found for third-order arcs).
+
+    For instance,  the following arc  P1P2P3 can be  decomposed into
+    two sub-arcs Q1Q2Q3 and R1R2R3:
+
+
+                    P2
+                   *
+                                    # on  curve
+                                    * off curve
+
+
+                                    original Bézier arc P1P2P3.
+                __---__
+             _--       --_
+           _-             -_
+          -                 -
+         /                   \
+        /                     \
+       #                       #
+     P1                         P3
+
+
+
+                    P2
+                   *
+
+
+
+                   Q3                 Decomposed into two subarcs
+          Q2                R2        Q1Q2Q3 and R1R2R3
+            *   __-#-__   *
+             _--       --_
+           _-       R1    -_          Q1 = P1         R3 = P3
+          -                 -         Q2 = (P1+P2)/2  R2 = (P2+P3)/2
+         /                   \
+        /                     \            Q3 = R1 = (Q2+R2)/2
+       #                       #
+     Q1                         R3    Note that Q2, R2, and Q3=R1
+                                      are on a single line which is
+                                      tangent to the curve.
+
+
+    We have then decomposed  a non-y-monotonic Bézier curve into two
+    smaller sub-arcs.  Note that in the above drawing, both sub-arcs
+    are monotonic, and that the extremum is then Q3=R1.  However, in
+    a  more general  case,  only  one sub-arc  is  guaranteed to  be
+    monotonic.  Getting back to our former example:
+
+
+                    Q2
+                   *
+
+                   __-x--_ R1
+                _--       #_
+          Q1  _-        Q3  -   R2
+             #               \ *
+                              -
+                               \
+                                \  R3
+                                 #
+
+
+    Here, we see that,  though Q1Q2Q3 is still non-monotonic, R1R2R3
+    is ever  descending: We  thus know that  it doesn't  contain the
+    extremum.  We can then re-subdivide Q1Q2Q3 into two sub-arcs and
+    go  on recursively,  stopping  when we  encounter two  monotonic
+    subarcs, or when the subarcs become simply too small.
+
+    We  will finally  find  the vertical  extremum.   Note that  the
+    iterative process of finding an extremum is called `flattening'.
+
+
+  e. Computing Profiles Coordinates
+
+    Once we have the height of each profile, we are able to allocate
+    it in the render pool.   The next task is to compute coordinates
+    for each scanline.
+
+    In  the case  of segments,  the computation  is straightforward,
+    using  the  Euclidean   algorithm  (also  known  as  Bresenham).
+    However, for Bézier arcs, the job is a little more complicated.
+
+    We assume  that all Béziers that  are part of a  profile are the
+    result of  flattening the curve,  which means that they  are all
+    y-monotonic (ascending  or descending, and never  flat).  We now
+    have  to compute the  intersections of  arcs with  the profile's
+    scanlines.  One  way is  to use a  similar scheme  to flattening
+    called `stepping'.
+
+
+                                 Consider this arc, going from P1 to
+      ---------------------      P3.  Suppose that we need to
+                                 compute its intersections with the
+                                 drawn scanlines.  As already
+      ---------------------      mentioned this can be done
+                                 directly, but the involved
+          * P2         _---# P3  algorithm is far too slow.
+      ------------- _--  --
+                  _-
+                _/               Instead, it is still possible to
+      ---------/-----------      use the decomposition property in
+              /                  the same recursive way, i.e.,
+             |                   subdivide the arc into subarcs
+      ------|--------------      until these get too small to cross
+            |                    more than one scanline!
+           |
+      -----|---------------      This is very easily done using a
+          |                      rasterizer-managed stack of
+          |                      subarcs.
+          # P1
+
+
+  f. Sweeping and Sorting the Spans
+
+    Once all our profiles have  been computed, we begin the sweep to
+    build (and fill) the spans.
+
+    As both the  TrueType and Type 1 specifications  use the winding
+    fill  rule (but  with opposite  directions), we  place,  on each
+    scanline, the present profiles in two separate lists.
+
+    One  list,  called  the  `left'  one,  only  contains  ascending
+    profiles, while  the other `right' list  contains the descending
+    profiles.
+
+    As  each glyph  is made  of  closed curves,  a simple  geometric
+    property ensures that  the two lists contain the  same number of
+    elements.
+
+    Creating spans is thus straightforward:
+
+    1. We sort each list in increasing horizontal order.
+
+    2. We pair  each value of  the left list with  its corresponding
+       value in the right list.
+
+
+                   /     /  |   |          For example, we have here
+                  /     /   |   |          four profiles.  Two of
+                >/     /    |   |  |       them are ascending (1 &
+              1//     /   ^ |   |  | 2     3), while the two others
+              //     //  3| |   |  v       are descending (2 & 4).
+              /     //4   | |   |          On the given scanline,
+           a /     /<       |   |          the left list is (1,3),
+      - - - *-----* - - - - *---* - - y -  and the right one is
+           /     / b       c|   |d         (4,2) (sorted).
+
+                                   There are then two spans, joining
+                                   1 to 4 (i.e. a-b) and 3 to 2
+                                   (i.e. c-d)!
+
+
+    Sorting doesn't necessarily  take much time, as in  99 cases out
+    of 100, the lists' order is  kept from one scanline to the next.
+    We can  thus implement it  with two simple  singly-linked lists,
+    sorted by a classic bubble-sort, which takes a minimum amount of
+    time when the lists are already sorted.
+
+    A  previous  version  of  the  rasterizer  used  more  elaborate
+    structures, like arrays to  perform `faster' sorting.  It turned
+    out that  this old scheme is  not faster than  the one described
+    above.
+
+    Once the spans  have been `created', we can  simply draw them in
+    the target bitmap.

+<p>While FreeType's auto-hinter doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The following lists the available properties together with the necessary macros and structures.</p>
+<p>Note that the auto-hinter's module name is &lsquo;autofitter&rsquo; for historical reasons.</p>
+
+<div class="section">

+
+<p><b>Experimental</b> <b>only</b></p>
+<p>The auto-hinter provides various script modules to hint glyphs. Examples of supported scripts are Latin or CJK. Before a glyph is auto-hinted, the Unicode character map of the font gets examined, and the script is then determined based on Unicode character ranges, see below.</p>
+<p>OpenType fonts, however, often provide much more glyphs than character codes (small caps, superscripts, ligatures, swashes, etc.), to be controlled by so-called &lsquo;features&rsquo;. Handling OpenType features can be quite complicated and thus needs a separate library on top of FreeType.</p>
+<p>The mapping between glyph indices and scripts (in the auto-hinter sense, see the <a href="ft2-auto_hinter.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_XXX</a> values) is stored as an array with &lsquo;num_glyphs&rsquo; elements, as found in the font's <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure. The &lsquo;glyph-to-script-map&rsquo; property returns a pointer to this array, which can be modified as needed. Note that the modification should happen before the first glyph gets processed by the auto-hinter so that the global analysis of the font shapes actually uses the modified mapping.</p>
+<p>The following example code demonstrates how to access it (omitting the error handling).</p>

+<p><b>Experimental</b> <b>only</b></p>
+<p>If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to activate the warp hinting code in the auto-hinter, this property switches warping on and off.</p>
+<p>Warping only works in &lsquo;light&rsquo; auto-hinting mode. The idea of the code is to slightly scale and shift a glyph along the non-hinted dimension (which is usually the horizontal axis) so that as much of its segments are aligned (more or less) to the grid. To find out a glyph's optimal scaling and shifting value, various parameter combinations are tried and scored.</p>
+<p>By default, warping is off. The example below shows how to switch on warping (omitting the error handling).</p>
+<pre class="colored">
+  FT_Library  library;
+  FT_Bool     warping = 1;
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, "autofitter",
+                            "warping", &amp;warping );

+<h4>note</h4>
+<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
+<p>This property can be set via the &lsquo;FREETYPE_PROPERTIES&rsquo; environment variable (using values 1 and 0 for &lsquo;on&rsquo; and &lsquo;off&rsquo;, respectively).</p>
+<p>The warping code can also change advance widths. Have a look at the &lsquo;lsb_delta&rsquo; and &lsquo;rsb_delta&rsquo; fields in the <a href="ft2-base_interface.html#FT_GlyphSlotRec">FT_GlyphSlotRec</a> structure for details on improving inter-glyph distances while rendering.</p>
+<p>Since warping is a global property of the auto-hinter it is best to change its value before rendering any face. Otherwise, you should reload all faces that get auto-hinted in &lsquo;light&rsquo; hinting mode.</p>

+
+<p><b>Experimental</b> *only,* <b>requires</b> <b>linear</b> <b>alpha</b> <b>blending</b> <b>and</b> <b>gamma</b> <b>correction</b></p>
+<p>Stem darkening emboldens glyphs at smaller sizes to make them more readable on common low-DPI screens when using linear alpha blending and gamma correction, see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. When not using linear alpha blending and gamma correction, glyphs will appear heavy and fuzzy!</p>
+<p>Gamma correction essentially lightens fonts since shades of grey are shifted to higher pixel values (=&nbsp;higher brightness) to match the original intention to the reality of our screens. The side-effect is that glyphs &lsquo;thin out&rsquo;. Mac OS&nbsp;X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore &lsquo;blacker&rsquo;. This counteracts the &lsquo;thinning out&rsquo; of glyphs, making text remain readable at smaller sizes. All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE.</p>
+<p>See the description of the CFF driver for algorithmic details. Total consistency with the CFF driver is currently not achieved because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones. The smaller the size (especially 9ppem and down), the higher the loss of emboldening versus the CFF driver.</p>
+<p>This property can be set via the &lsquo;FREETYPE_PROPERTIES&rsquo; environment variable similar to the CFF driver.</p>

+<p>A handle to a FreeType library instance. Each &lsquo;library&rsquo; is completely independent from the others; it is the &lsquo;root&rsquo; of a set of objects like fonts, faces, sizes, etc.</p>
+<p>It also embeds a memory manager (see <a href="ft2-system_interface.html#FT_Memory">FT_Memory</a>), as well as a scan-line converter object (see <a href="ft2-raster.html#FT_Raster">FT_Raster</a>).</p>
+<p>In multi-threaded applications it is easiest to use one &lsquo;FT_Library&rsquo; object per thread. In case this is too cumbersome, a single &lsquo;FT_Library&rsquo; object across threads is possible also (since FreeType version 2.5.6), as long as a mutex lock is used around <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> and <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>.</p>

+<h4>note</h4>
+<p>By default, FreeType automatically synthesizes a Unicode charmap for PostScript fonts, using their glyph names dictionaries. However, it also reports the encodings defined explicitly in the font file, for the cases when they are needed, with the Adobe values as well.</p>
+<p>FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE). Use <a href="ft2-bdf_fonts.html#FT_Get_BDF_Charset_ID">FT_Get_BDF_Charset_ID</a> to find out which encoding is really present. If, for example, the &lsquo;cs_registry&rsquo; field is &lsquo;KOI8&rsquo; and the &lsquo;cs_encoding&rsquo; field is &lsquo;R&rsquo;, the font is encoded in KOI8-R.</p>
+<p>FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver. Use <a href="ft2-winfnt_fonts.html#FT_Get_WinFNT_Header">FT_Get_WinFNT_Header</a> and examine the &lsquo;charset&rsquo; field of the <a href="ft2-winfnt_fonts.html#FT_WinFNT_HeaderRec">FT_WinFNT_HeaderRec</a> structure to find out which encoding is really present. For example, <a href="ft2-winfnt_fonts.html#FT_WinFNT_ID_XXX">FT_WinFNT_ID_CP1251</a> (204) means Windows code page 1251 (for Russian).</p>
+<p>FT_ENCODING_NONE is set if &lsquo;platform_id&rsquo; is <a href="ft2-truetype_tables.html#TT_PLATFORM_XXX">TT_PLATFORM_MACINTOSH</a> and &lsquo;encoding_id&rsquo; is not <a href="ft2-truetype_tables.html#TT_MAC_ID_XXX">TT_MAC_ID_ROMAN</a> (otherwise it is set to FT_ENCODING_APPLE_ROMAN).</p>
+<p>If &lsquo;platform_id&rsquo; is <a href="ft2-truetype_tables.html#TT_PLATFORM_XXX">TT_PLATFORM_MACINTOSH</a>, use the function <a href="ft2-truetype_tables.html#FT_Get_CMap_Language_ID">FT_Get_CMap_Language_ID</a> to query the Mac language ID that may be needed to be able to distinguish Apple encoding variants. See</p>
+<p><a href="http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt">http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt</a></p>
+<p>to get an idea how to do that. Basically, if the language ID is&nbsp;0, don't use it, otherwise subtract 1 from the language ID. Then examine &lsquo;encoding_id&rsquo;. If, for example, &lsquo;encoding_id&rsquo; is <a href="ft2-truetype_tables.html#TT_MAC_ID_XXX">TT_MAC_ID_ROMAN</a> and the language ID (minus&nbsp;1) is &lsquo;TT_MAC_LANGID_GREEK&rsquo;, it is the Greek encoding, not Roman. <a href="ft2-truetype_tables.html#TT_MAC_ID_XXX">TT_MAC_ID_ARABIC</a> with &lsquo;TT_MAC_LANGID_FARSI&rsquo; means the Farsi variant the Arabic encoding.</p>

+<h4>note</h4>
+<p>The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in <a href="ft2-base_interface.html#FT_FaceRec">FT_FaceRec</a>.</p>
+<p>Note that due to glyph hinting, these values might not be exact for certain fonts. Thus they must be treated as unreliable with an error margin of at least one pixel!</p>
+<p>Indeed, the only way to get the exact metrics is to render <i>all</i> glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.</p>
+<p>The FT_Size_Metrics structure is valid for bitmap fonts also.</p>

+<h4>note</h4>
+<p>If <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a> is called with default flags (see <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_DEFAULT</a>) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type&nbsp;1 formats).</p>
+<p>This image can later be converted into a bitmap by calling <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. This function finds the current renderer for the native image's format, then invokes it.</p>
+<p>The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in &lsquo;slot-&gt;bitmap&rsquo;.</p>
+<p>Note that &lsquo;slot-&gt;bitmap_left&rsquo; and &lsquo;slot-&gt;bitmap_top&rsquo; are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, &lsquo;slot-&gt;format&rsquo; is also changed to <a href="ft2-basic_types.html#FT_Glyph_Format">FT_GLYPH_FORMAT_BITMAP</a>.</p>
+<p>Here is a small pseudo code fragment that shows how to use &lsquo;lsb_delta&rsquo; and &lsquo;rsb_delta&rsquo;:</p>
+<pre class="colored">
+  FT_Pos  origin_x       = 0;
+  FT_Pos  prev_rsb_delta = 0;
+
+
+  for all glyphs do
+    &lt;compute kern between current and previous glyph and add it to
+     `origin_x'&gt;
+
+    &lt;load glyph with `FT_Load_Glyph'&gt;
+
+    if ( prev_rsb_delta - face-&gt;glyph-&gt;lsb_delta &gt;= 32 )
+      origin_x -= 64;
+    else if ( prev_rsb_delta - face-&gt;glyph-&gt;lsb_delta &lt; -32 )
+      origin_x += 64;
+
+    prev_rsb_delta = face-&gt;glyph-&gt;rsb_delta;
+
+    &lt;save glyph image, or render glyph, or ...&gt;
+
+    origin_x += face-&gt;glyph-&gt;advance.x;
+  endfor
+</pre>
+<p>If you use strong auto-hinting, you <b>must</b> apply these delta values! Otherwise you will experience far too large inter-glyph spacing at small rendering sizes in most cases. Note that it doesn't harm to use the above code for other hinting modes also, since the delta values are zero then.</p>

+<h4>note</h4>
+<p>Windows FNT: The nominal size given in a FNT font is not reliable. Thus when the driver finds it incorrect, it sets &lsquo;size&rsquo; to some calculated values and sets &lsquo;x_ppem&rsquo; and &lsquo;y_ppem&rsquo; to the pixel width and height given in the font, respectively.</p>
+<p>TrueType embedded bitmaps: &lsquo;size&rsquo;, &lsquo;width&rsquo;, and &lsquo;height&rsquo; values are not contained in the bitmap strike itself. They are computed from the global font parameters.</p>

+<p>To get meaningful results, font scaling values must be set with functions like <a href="ft2-base_interface.html#FT_Set_Char_Size">FT_Set_Char_Size</a> before calling FT_Render_Glyph.</p>
+<p>When FreeType outputs a bitmap of a glyph, it really outputs an alpha coverage map. If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright). If a pixel is only 50% covered (value 0x80), the pixel is made 50% black (50% bright or a middle shade of grey). 0% covered means 0% black (100% bright or white).</p>
+<p>On high-DPI screens like on smartphones and tablets, the pixels are so small that their chance of being completely covered and therefore completely black are fairly good. On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p>
+<p>This is relevant because all our screens have a second problem: they are not linear. 1&nbsp;+&nbsp;1 is not&nbsp;2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8&nbsp;bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma&nbsp;2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness – 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or &lsquo;dirt&rsquo; around it. The situation is especially ugly for diagonal stems like in &lsquo;w&rsquo; glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p>
+<p>The blending function for placing text over a background is</p>
+<pre class="colored">
+  dst = alpha * src + (1 - alpha) * dst    ,
+</pre>
+<p>which is known as the OVER operator.</p>
+<p>To correctly composite an antialiased pixel of a glyph onto a surface,</p>
+<p>1. take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p>
+<p>2. use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p>
+<p>3. apply inverse gamma to the blended pixel and write it back to the image.</p>
+<p>Internal testing at Adobe found that a target inverse gamma of&nbsp;1.8 for step&nbsp;3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p>
+<p>This process can cost performance. There is an approximation that does not need to know about the background color; see <a href="https://bel.fi/alankila/lcd/">https://bel.fi/alankila/lcd/</a> and <a href="https://bel.fi/alankila/lcd/alpcor.html">https://bel.fi/alankila/lcd/alpcor.html</a> for details.</p>
+<p><b>ATTENTION</b>: Linear blending is even more important when dealing with subpixel-rendered glyphs to prevent color-fringing! A subpixel-rendered glyph must first be filtered with a filter that gives equal weight to the three color primaries and does not exceed a sum of 0x100, see section &lsquo;<a href="ft2-lcd_filtering.html#lcd_filtering">LCD Filtering</a>&rsquo;. Then the only difference to gray linear blending is that subpixel-rendered linear blending is done 3&nbsp;times per pixel: red foreground subpixel to red background subpixel and so on for green and blue.</p>

+<h4>note</h4>
+<p>By default, hinting is enabled and the font's native hinter (see <a href="ft2-base_interface.html#FT_FACE_FLAG_XXX">FT_FACE_FLAG_HINTER</a>) is preferred over the auto-hinter. You can disable hinting by setting <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_HINTING</a> or change the precedence by setting <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_FORCE_AUTOHINT</a>. You can also set <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_AUTOHINT</a> in case you don't want the auto-hinter to be used at all.</p>
+<p>See the description of <a href="ft2-base_interface.html#FT_FACE_FLAG_XXX">FT_FACE_FLAG_TRICKY</a> for a special exception (affecting only a handful of Asian fonts).</p>
+<p>Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See <a href="ft2-base_interface.html#FT_LOAD_TARGET_XXX">FT_LOAD_TARGET_XXX</a> for details.</p>
+<p>Note that the auto-hinter needs a valid Unicode cmap (either a native one or synthesized by FreeType) for producing correct results. If a font provides an incorrect mapping (for example, assigning the character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a mathematical integral sign), the auto-hinter might produce useless results.</p>

+
+<h4>note</h4>
+<p>Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:</p>
+<pre class="colored">
+  #define FT_IMAGE_TAG( value, _x1, _x2, _x3, _x4 )  value
+</pre>
+<p>to get a simple enumeration without assigning special numbers.</p>

+<p>Integer properties are always stored as &lsquo;signed&rsquo; within PCF fonts; consequently, <a href="ft2-bdf_fonts.html#BDF_PropertyType">BDF_PROPERTY_TYPE_CARDINAL</a> is a possible return value for BDF fonts only.</p>
+<p>In case of error, &lsquo;aproperty-&gt;type&rsquo; is always set to <a href="ft2-bdf_fonts.html#BDF_PropertyType">BDF_PROPERTY_TYPE_NONE</a>.</p>

+<p>In certain builds of the library, bzip2 compression recognition is automatically handled when calling <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a bzip2 compressed stream from it and re-open the face with it.</p>
+<p>This function may return &lsquo;FT_Err_Unimplemented_Feature&rsquo; if your build of FreeType was not compiled with bzip2 support.</p>

+
+<p>This section describes the FreeType&nbsp;2 cache sub-system, which is used to limit the number of concurrently opened <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.</p>
+<p>Note that all types and functions begin with the &lsquo;FTC_&rsquo; prefix.</p>
+<p>The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:</p>
+<p>First, available or installed font faces are uniquely identified by <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.</p>
+<p>Second, the cache calls, only when needed, a client-provided function to convert an <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> into a new <a href="ft2-base_interface.html#FT_Face">FT_Face</a> object. The latter is then completely managed by the cache, including its termination through <a href="ft2-base_interface.html#FT_Done_Face">FT_Done_Face</a>. To monitor termination of face objects, the finalizer callback in the &lsquo;generic&rsquo; field of the <a href="ft2-base_interface.html#FT_Face">FT_Face</a> object can be used, which might also be used to store the <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> of the face.</p>
+<p>Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a>. However, more complex schemes are also possible.</p>
+<p>Note that for the cache to work correctly, the face ID values must be <b>persistent</b>, which means that the contents they point to should not change at runtime, or that their value should not become invalid.</p>
+<p>If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call <a href="ft2-cache_subsystem.html#FTC_Manager_RemoveFaceID">FTC_Manager_RemoveFaceID</a> as soon as possible, to let the cache get rid of any references to the old <a href="ft2-cache_subsystem.html#FTC_FaceID">FTC_FaceID</a> it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.</p>
+<p>To use the cache, start with calling <a href="ft2-cache_subsystem.html#FTC_Manager_New">FTC_Manager_New</a> to create a new <a href="ft2-cache_subsystem.html#FTC_Manager">FTC_Manager</a> object, which models a single cache instance. You can then look up <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects with <a href="ft2-cache_subsystem.html#FTC_Manager_LookupFace">FTC_Manager_LookupFace</a> and <a href="ft2-cache_subsystem.html#FTC_Manager_LookupSize">FTC_Manager_LookupSize</a>, respectively.</p>
+<p>If you want to use the charmap caching, call <a href="ft2-cache_subsystem.html#FTC_CMapCache_New">FTC_CMapCache_New</a>, then later use <a href="ft2-cache_subsystem.html#FTC_CMapCache_Lookup">FTC_CMapCache_Lookup</a> to perform the equivalent of <a href="ft2-base_interface.html#FT_Get_Char_Index">FT_Get_Char_Index</a>, only much faster.</p>
+<p>If you want to use the <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> caching, call <a href="ft2-cache_subsystem.html#FTC_ImageCache">FTC_ImageCache</a>, then later use <a href="ft2-cache_subsystem.html#FTC_ImageCache_Lookup">FTC_ImageCache_Lookup</a> to retrieve the corresponding <a href="ft2-glyph_management.html#FT_Glyph">FT_Glyph</a> objects from the cache.</p>
+<p>If you need lots of small bitmaps, it is much more memory efficient to call <a href="ft2-cache_subsystem.html#FTC_SBitCache_New">FTC_SBitCache_New</a> followed by <a href="ft2-cache_subsystem.html#FTC_SBitCache_Lookup">FTC_SBitCache_Lookup</a>. This returns <a href="ft2-cache_subsystem.html#FTC_SBitRec">FTC_SBitRec</a> structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).</p>
+<p>We hope to also provide a kerning cache in the near future.</p>

+<p>The manager intentionally limits the total number of opened <a href="ft2-base_interface.html#FT_Face">FT_Face</a> and <a href="ft2-base_interface.html#FT_Size">FT_Size</a> objects to control memory usage. See the &lsquo;max_faces&rsquo; and &lsquo;max_sizes&rsquo; parameters of <a href="ft2-cache_subsystem.html#FTC_Manager_New">FTC_Manager_New</a>.</p>
+<p>The manager is also used to cache &lsquo;nodes&rsquo; of various types while limiting their total memory usage.</p>
+<p>All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones.</p>

+<p>While FreeType's CFF driver doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The list below gives the available properties together with the necessary macros and structures.</p>
+<p>The CFF driver's module name is &lsquo;cff&rsquo;.</p>
+<p><b>Hinting</b> <b>and</b> <b>antialiasing</b> <b>principles</b> <b>of</b> <b>the</b> <b>new</b> <b>engine</b></p>
+<p>The rasterizer is positioning horizontal features (e.g., ascender height &amp; x-height, or crossbars) on the pixel grid and minimizing the amount of antialiasing applied to them, while placing vertical features (vertical stems) on the pixel grid without hinting, thus representing the stem position and weight accurately. Sometimes the vertical stems may be only partially black. In this context, &lsquo;antialiasing&rsquo; means that stems are not positioned exactly on pixel borders, causing a fuzzy appearance.</p>
+<p>There are two principles behind this approach.</p>
+<p>1) No hinting in the horizontal direction: Unlike &lsquo;superhinted&rsquo; TrueType, which changes glyph widths to accommodate regular inter-glyph spacing, Adobe's approach is &lsquo;faithful to the design&rsquo; in representing both the glyph width and the inter-glyph spacing designed for the font. This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p>
+<p>One of the reasons to not hint horizontally is antialiasing for LCD screens: The pixel geometry of modern displays supplies three vertical sub-pixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the sub-pixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale antialiasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p>
+<p>2) Alignment in the vertical direction: Weights and spacing along the y&nbsp;axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of 1/3 pixels) is less of a problem.</p>
+<p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called &lsquo;blue zones&rsquo;) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p>
+<p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be &lsquo;captured&rsquo; and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down. Unless there are conflicting hstems, the smallest movement is taken to minimize distortion.</p>

+<h3 id="hinting-engine(cff)">hinting-engine</h3>
+
+<p>Thanks to Adobe, which contributed a new hinting (and parsing) engine, an application can select between &lsquo;freetype&rsquo; and &lsquo;adobe&rsquo; if compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration macro isn't defined, &lsquo;hinting-engine&rsquo; does nothing.</p>
+<p>The default engine is &lsquo;freetype&rsquo; if CFF_CONFIG_OPTION_OLD_ENGINE is defined, and &lsquo;adobe&rsquo; otherwise.</p>
+<p>The following example code demonstrates how to select Adobe's hinting engine (omitting the error handling).</p>
+<pre class="colored">
+  FT_Library  library;
+  FT_UInt     hinting_engine = FT_CFF_HINTING_ADOBE;
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, "cff",
+                            "hinting-engine", &amp;hinting_engine );
+</pre>
+
+<h4>note</h4>
+<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
+<p>This property can be set via the &lsquo;FREETYPE_PROPERTIES&rsquo; environment variable (using values &lsquo;adobe&rsquo; or &lsquo;freetype&rsquo;).</p>
+

+<table class="index-toc-link"><tr><td class="left">[<a href="ft2-index.html">Index</a>]</td><td class="middle">[<a href="#">Top</a>]</td><td class="right">[<a href="ft2-toc.html">TOC</a>]</td></tr></table></div>
+
+<div class="section">
+<h3 id="no-stem-darkening(cff)">no-stem-darkening</h3>
+
+<p>By default, the Adobe CFF engine darkens stems at smaller sizes, regardless of hinting, to enhance contrast. This feature requires a rendering system with proper gamma correction. Setting this property, stem darkening gets switched off.</p>
+<p>Note that stem darkening is never applied if <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a> is set.</p>
+<pre class="colored">
+  FT_Library  library;
+  FT_Bool     no_stem_darkening = TRUE;
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, "cff",
+                            "no-stem-darkening", &amp;no_stem_darkening );

+<div class="section">
+<h3 id="darkening-parameters(cff)">darkening-parameters</h3>
+
+<p>By default, the Adobe CFF engine darkens stems as follows (if the &lsquo;no-stem-darkening&rsquo; property isn't set):</p>
+<pre class="colored">
+  stem width &lt;= 0.5px:   darkening amount = 0.4px
+  stem width  = 1px:     darkening amount = 0.275px
+  stem width  = 1.667px: darkening amount = 0.275px
+  stem width &gt;= 2.333px: darkening amount = 0px
+</pre>
+<p>and piecewise linear in-between. At configuration time, these four control points can be set with the macro &lsquo;CFF_CONFIG_OPTION_DARKENING_PARAMETERS&rsquo;. At runtime, the control points can be changed using the &lsquo;darkening-parameters&rsquo; property, as the following example demonstrates.</p>
+<pre class="colored">
+  FT_Library  library;
+  FT_Int      darken_params[8] = {  500, 300,   // x1, y1
+                                   1000, 200,   // x2, y2
+                                   1500, 100,   // x3, y3
+                                   2000,   0 }; // x4, y4
+
+
+  FT_Init_FreeType( &amp;library );
+
+  FT_Property_Set( library, "cff",
+                            "darkening-parameters", darken_params );
+</pre>
+<p>The x&nbsp;values give the stem width, and the y&nbsp;values the darkening amount. The unit is 1000th of pixels. All coordinate values must be positive; the x&nbsp;values must be monotonically increasing; the y&nbsp;values must be monotonically decreasing and smaller than or equal to 500 (corresponding to half a pixel); the slope of each linear piece must be shallower than -1 (e.g., -.4).</p>
+
+<h4>note</h4>
+<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
+<p>This property can be set via the &lsquo;FREETYPE_PROPERTIES&rsquo; environment variable, using eight comma-separated integers without spaces. Here the above example, using &lsquo;\&rsquo; to break the line for readability.</p>

+<h4>note</h4>
+<p>This function has been optimized for the case where the absolute value of &lsquo;a&rsquo; is less than 2048, and &lsquo;b&rsquo; is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.</p>
+<p>As a conclusion, always try to place a 16.16 factor as the <i>second</i> argument of this function; this can make a great difference.</p>

+<p>The list below is taken verbatim from the file &lsquo;fterrdef.h&rsquo; (loaded automatically by including &lsquo;FT_FREETYPE_H&rsquo;). The first argument of the &lsquo;FT_ERROR_DEF_&rsquo; macro is the error label; by default, the prefix &lsquo;FT_Err_&rsquo; gets added so that you get error names like &lsquo;FT_Err_Cannot_Open_Resource&rsquo;. The second argument is the error code, and the last argument an error string, which is not used by FreeType.</p>
+<p>Within your application you should <b>only</b> use error names and <b>never</b> its numeric values! The latter might (and actually do) change in forthcoming FreeType versions.</p>
+<p>Macro &lsquo;FT_NOERRORDEF_&rsquo; defines &lsquo;FT_Err_Ok&rsquo;, which is always zero. See the &lsquo;Error Enumerations&rsquo; subsection how to automatically generate a list of error strings.</p>

+<h1>FreeType-2.7.1 API Reference</h1>
+
+<h1 id="error_enumerations">Error Enumerations</h1>
+
+<p>The header file &lsquo;fterrors.h&rsquo; (which is automatically included by &lsquo;freetype.h&rsquo; defines the handling of FreeType's enumeration constants. It can also be used to generate error message strings with a small macro trick explained below.</p>
+<p><b>Error</b> <b>Formats</b></p>
+<p>The configuration macro FT_CONFIG_OPTION_USE_MODULE_ERRORS can be defined in &lsquo;ftoption.h&rsquo; in order to make the higher byte indicate the module where the error has happened (this is not compatible with standard builds of FreeType&amp;nbsp;2, however). See the file &lsquo;ftmoderr.h&rsquo; for more details.</p>
+<p><b>Error</b> <b>Message</b> <b>Strings</b></p>
+<p>Error definitions are set up with special macros that allow client applications to build a table of error message strings. The strings are not included in a normal build of FreeType&amp;nbsp;2 to save space (most client applications do not use them).</p>
+<p>To do so, you have to define the following macros before including this file.</p>
+<pre class="colored">
+  FT_ERROR_START_LIST
+</pre>
+<p>This macro is called before anything else to define the start of the error list. It is followed by several FT_ERROR_DEF calls.</p>
+<pre class="colored">
+  FT_ERROR_DEF( e, v, s )
+</pre>
+<p>This macro is called to define one single error. &lsquo;e&rsquo; is the error code identifier (e.g., &lsquo;Invalid_Argument&rsquo;), &lsquo;v&rsquo; is the error's numerical value, and &lsquo;s&rsquo; is the corresponding error string.</p>
+<pre class="colored">
+  FT_ERROR_END_LIST
+</pre>
+<p>This macro ends the list.</p>
+<p>Additionally, you have to undefine &lsquo;FTERRORS_H_&rsquo; before #including this file.</p>
+<p>Here is a simple example.</p>
+<pre class="colored">
+  #undef FTERRORS_H_
+  #define FT_ERRORDEF( e, v, s )  { e, s },
+  #define FT_ERROR_START_LIST     {
+  #define FT_ERROR_END_LIST       { 0, NULL } };
+
+  const struct
+  {
+    int          err_code;
+    const char*  err_msg;
+  } ft_errors[] =
+
+  #include FT_ERRORS_H
+</pre>
+<p>Note that &lsquo;FT_Err_Ok&rsquo; is <i>not</i> defined with &lsquo;FT_ERRORDEF&rsquo; but with &lsquo;FT_NOERRORDEF&rsquo;; it is always zero.</p>

+<p>If the glyph has been loaded with <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a>, &lsquo;bbox_mode&rsquo; must be set to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_UNSCALED</a> to get unscaled font units in 26.6 pixel format. The value <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_SUBPIXELS</a> is another name for this constant.</p>
+<p>If the font is tricky and the glyph has been loaded with <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a>, the resulting CBox is meaningless. To get reasonable values for the CBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the CBox, which can be eventually converted back to font units.</p>
+<p>Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:</p>
+<pre class="colored">
+  width  = bbox.xMax - bbox.xMin;
+  height = bbox.yMax - bbox.yMin;
+</pre>
+<p>Note also that for 26.6 coordinates, if &lsquo;bbox_mode&rsquo; is set to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_GRIDFIT</a>, the coordinates will also be grid-fitted, which corresponds to:</p>

+  bbox.yMin = FLOOR(bbox.yMin);
+  bbox.xMax = CEILING(bbox.xMax);
+  bbox.yMax = CEILING(bbox.yMax);

+<p>To get the bbox in grid-fitted pixel coordinates, set &lsquo;bbox_mode&rsquo; to <a href="ft2-glyph_management.html#FT_Glyph_BBox_Mode">FT_GLYPH_BBOX_PIXELS</a>.</p>

+
+<p>Many CJK characters have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Ideographic Variation Sequences (IVS), consisting of a Unicode base character and one of 240 variant selectors (U+E0100-U+E01EF), instead of further extending the already huge code range for CJK characters.</p>
+<p>An IVS is registered and unique; for further details please refer to Unicode Technical Standard #37, the Ideographic Variation Database:</p>
+<p><a href="http://www.unicode.org/reports/tr37/">http://www.unicode.org/reports/tr37/</a></p>
+<p>To date (November 2014), the character with the most variants is U+9089, having 32 such IVS.</p>
+<p>Adobe and MS decided to support IVS with a new cmap subtable (format&nbsp;14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variants supported by the font.</p>
+<p>A variant may be either &lsquo;default&rsquo; or &lsquo;non-default&rsquo;. A default variant is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variant is a different glyph.</p>

+<p>The following macros are defined to the name of specific FreeType&nbsp;2 header files. They can be used directly in #include statements as in:</p>
+<pre class="colored">
+  #include FT_FREETYPE_H
+  #include FT_MULTIPLE_MASTERS_H
+  #include FT_GLYPH_H
+</pre>
+<p>There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3&nbsp;naming rule required by DOS (and &lsquo;FT_MULTIPLE_MASTERS_H&rsquo; is a lot more meaningful than &lsquo;ftmm.h&rsquo;).</p>
+<p>The second reason is that it allows for more flexibility in the way FreeType&nbsp;2 is installed on a given system.</p>

+<h1>FreeType-2.7.1 API Reference</h1>
+
+<h1 id="header_inclusion">FreeType's header inclusion scheme</h1>
+
+<p>To be as flexible as possible (and for historical reasons), FreeType uses a very special inclusion scheme to load header files, for example</p>
+<pre class="colored">
+  #include &lt;ft2build.h&gt;
+
+  #include FT_FREETYPE_H
+  #include FT_OUTLINE_H
+</pre>
+<p>A compiler and its preprocessor only needs an include path to find the file &lsquo;ft2build.h&rsquo;; the exact locations and names of the other FreeType header files are hidden by preprocessor macro names, loaded by &lsquo;ft2build.h&rsquo;. The API documentation always gives the header macro name needed for a particular function.</p>

+<p>This section contains various functions used to perform so-called &lsquo;incremental&rsquo; glyph loading. This is a mode where all glyphs loaded from a given <a href="ft2-base_interface.html#FT_Face">FT_Face</a> are provided by the client application.</p>
+<p>Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.</p>
+<p>To enable this mode, you must use <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>, passing an <a href="ft2-base_interface.html#FT_Parameter">FT_Parameter</a> with the <a href="ft2-incremental.html#FT_PARAM_TAG_INCREMENTAL">FT_PARAM_TAG_INCREMENTAL</a> tag and an <a href="ft2-incremental.html#FT_Incremental_Interface">FT_Incremental_Interface</a> value.

+<p>Subpixel rendering exploits the color-striped structure of LCD pixels, increasing the available resolution in the direction of the stripe (usually horizontal RGB) by a factor of&nbsp;3. Since these subpixels are color pixels, using them unfiltered creates severe color fringes. Use the <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. The filter sacrifices some of the higher resolution to reduce color fringes, making the glyph image slightly blurrier. Positional improvements will remain.</p>
+<p>Note that no filter is active by default, and that this function is <b>not</b> implemented in default builds of the library. You need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your &lsquo;ftoption.h&rsquo; file in order to activate it and explicitly call <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> to enable it.</p>
+<p>A filter should have two properties:</p>
+<p>1) It should be normalized, meaning the sum of the 5&nbsp;components should be 256 (0x100). It is possible to go above or under this target sum, however: going under means tossing out contrast, going over means invoking clamping and thereby non-linearities that increase contrast somewhat at the expense of greater distortion and color-fringing. Contrast is better enhanced through stem darkening.</p>
+<p>2) It should be color-balanced, meaning a filter &lsquo;{&nbsp;a, b, c, b, a&nbsp;}&rsquo; where a&nbsp;+ b&nbsp;=&nbsp;c. It distributes the computed coverage for one subpixel to all subpixels equally, sacrificing some won resolution but drastically reducing color-fringing. Positioning improvements remain! Note that color-fringing can only really be minimized when using a color-balanced filter and alpha-blending the glyph onto a surface in linear space; see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>.</p>
+<p>Regarding the form, a filter can be a &lsquo;boxy&rsquo; filter or a &lsquo;beveled&rsquo; filter. Boxy filters are sharper but are less forgiving of non-ideal gamma curves of a screen (viewing angles!), beveled filters are fuzzier but more tolerant.</p>
+<p>Examples:</p>
+<p>- [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor normalized.</p>
+<p>- [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not normalized.</p>
+<p>- [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not balanced.</p>
+<p>- [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not balanced.</p>
+<p>- [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost balanced.</p>
+<p>- [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost balanced.</p>
+<p>The filter affects glyph bitmaps rendered through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>, <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a>, and <a href="ft2-base_interface.html#FT_Load_Char">FT_Load_Char</a>. It does <i>not</i> affect the output of <a href="ft2-outline_processing.html#FT_Outline_Render">FT_Outline_Render</a> and <a href="ft2-outline_processing.html#FT_Outline_Get_Bitmap">FT_Outline_Get_Bitmap</a>.</p>
+<p>If this feature is activated, the dimensions of LCD glyph bitmaps are either wider or taller than the dimensions of the corresponding outline with regard to the pixel grid. For example, for <a href="ft2-base_interface.html#FT_Render_Mode">FT_RENDER_MODE_LCD</a>, the filter adds 3&nbsp;subpixels to the left, and 3&nbsp;subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p>
+<p>It is important to understand that linear alpha blending and gamma correction is critical for correctly rendering glyphs onto surfaces without artifacts and even more critical when subpixel rendering is involved.</p>
+<p>Each of the 3&nbsp;alpha values (subpixels) is independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel. The distribution of density values by the color-balanced filter assumes alpha blending is done in linear space; only then color artifacts cancel out.</p>

Note that while color-fringing is reduced, it can only be minimized by using linear alpha blending and gamma correction to render glyphs onto surfaces.

+<p>It is a boxy, normalized, and color-balanced three-tap filter that is less forgiving to screens with non-ideal gamma curves and viewing angles. This filter works best when the rendering system uses linear alpha blending and gamma correction to render glyphs onto surfaces. The light filter weights are [0x00 0x55 0x56 0x55 0x00].</p>

+<p>This filter corresponds to the original libXft color filter. It provides high contrast output but can exhibit really bad color fringes if glyphs are not extremely well hinted to the pixel grid. In other words, it only works well if the TrueType bytecode interpreter is enabled <b>and</b> high-quality hinted fonts are used.</p>

+<p>The source stream must be opened <i>before</i> calling this function.</p>
+<p>Calling the internal function &lsquo;FT_Stream_Close&rsquo; on the new stream will <b>not</b> call &lsquo;FT_Stream_Close&rsquo; on the source stream. None of the stream objects will be released to the heap.</p>
+<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream</p>
+<p>In certain builds of the library, LZW compression recognition is automatically handled when calling <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.</p>
+<p>This function may return &lsquo;FT_Err_Unimplemented_Feature&rsquo; if your build of FreeType was not compiled with LZW support.</p>

+<p>If the font is tricky and the glyph has been loaded with <a href="ft2-base_interface.html#FT_LOAD_XXX">FT_LOAD_NO_SCALE</a>, the resulting BBox is meaningless. To get reasonable values for the BBox it is necessary to load the glyph at a large ppem value (so that the hinting instructions can properly shift and scale the subglyphs), then extracting the BBox, which can be eventually converted back to font units.</p>

+<p>When creating a new face object (e.g., with <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a>), an <a href="ft2-base_interface.html#FT_Size">FT_Size</a> object is automatically created and used to store all pixel-size dependent information, available in the &lsquo;face-&gt;size&rsquo; field.</p>
+<p>It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See <a href="ft2-sizes_management.html#FT_New_Size">FT_New_Size</a> and <a href="ft2-sizes_management.html#FT_Done_Size">FT_Done_Size</a>.</p>

+
+<p>While FreeType's TrueType driver doesn't expose API functions by itself, it is possible to control its behaviour with <a href="ft2-module_management.html#FT_Property_Set">FT_Property_Set</a> and <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a>. The following lists the available properties together with the necessary macros and structures.</p>
+<p>The TrueType driver's module name is &lsquo;truetype&rsquo;.</p>
+<p>We start with a list of definitions, kindly provided by Greg Hitchcock.</p>
+<p><i>Bi-Level</i> <i>Rendering</i></p>
+<p>Monochromatic rendering, exclusively used in the early days of TrueType by both Apple and Microsoft. Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, &lsquo;hdmx&rsquo; and &lsquo;LTSH&rsquo;, to cache hinting widths across multiple sizes and device aspect ratios.</p>
+<p><i>Font</i> <i>Smoothing</i></p>
+<p>Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering.</p>
+<p><i>ClearType</i> <i>Rendering</i></p>
+<p>Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls &lsquo;natural widths&rsquo; ClearType, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec21">http://www.beatstamm.com/typography/RTRCh4.htm#Sec21</a>. Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode.</p>
+<p><i>ClearType</i> <i>Compatible</i> <i>Widths</i></p>
+<p>One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec20">http://www.beatstamm.com/typography/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</p>
+<p><i>ClearType</i> <i>Subpixel</i> <i>Positioning</i></p>
+<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this &lsquo;natural mode&rsquo;, not to be confused with GDI's &lsquo;natural widths&rsquo;. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec22">http://www.beatstamm.com/typography/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p>
+<p><i>ClearType</i> <i>Backwards</i> <i>Compatibility</i></p>
+<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec1">http://www.beatstamm.com/typography/RTRCh4.htm#Sec1</a> and <a href="http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backwards compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backwards compatibility mode.</p>
+<p><i>Native</i> <i>ClearType</i> <i>Mode</i></p>
+<p>(Not to be confused with &lsquo;natural widths&rsquo;.) This mode removes all the exceptions in the TrueType interpreter when running with ClearType. Any issues on widths would still apply, though.</p>

+<h3 id="interpreter-version">interpreter-version</h3>
+<p>Defined in FT_TRUETYPE_DRIVER_H (freetype/ftttdrv.h).</p>
+<pre>
+   *   Currently, three versions are available, two representing the
+   *   bytecode interpreter with subpixel hinting support (old `Infinality'
+   *   code and new stripped-down and higher performance `minimal' code) and
+   *   one without, respectively.  The default is subpixel support if
+   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+   *   otherwise (since it isn't available then).
+   *
+   *   If subpixel hinting is on, many TrueType bytecode instructions behave
+   *   differently compared to B/W or grayscale rendering (except if `native
+   *   ClearType' is selected by the font).  Microsoft's main idea is to
+   *   render at a much increased horizontal resolution, then sampling down
+   *   the created output to subpixel precision.  However, many older fonts
+   *   are not suited to this and must be specially taken care of by
+   *   applying (hardcoded) tweaks in Microsoft's interpreter.
+   *
+   *   Details on subpixel hinting and some of the necessary tweaks can be
+   *   found in Greg Hitchcock's whitepaper at
+   *   `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'. 
+   *   Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+   *   or 6x5 supersampling) like discussed in the paper.  Depending on the
+   *   chosen interpreter, it simply ignores instructions on vertical stems
+   *   to arrive at very similar results.
+   *
+   *   The following example code demonstrates how to deactivate subpixel
+   *   hinting (omitting the error handling).

+<h4>note</h4>
+<p>This property controls the behaviour of the bytecode interpreter and thus how outlines get hinted. It does <b>not</b> control how glyph get rasterized! In particular, it does not control subpixel color filtering.</p>
+<p>If FreeType has not been compiled with the configuration option FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version&nbsp;38 or&nbsp;40 causes an &lsquo;FT_Err_Unimplemented_Feature&rsquo; error.</p>
+<p>Depending on the graphics framework, Microsoft uses different bytecode and rendering engines. As a consequence, the version numbers returned by a call to the &lsquo;GETINFO&rsquo; bytecode instruction are more convoluted than desired.</p>
+<p>Here are two tables that try to shed some light on the possible values for the MS rasterizer engine, together with the additional features introduced by it.</p>

+<p>The &lsquo;version&rsquo; field gives a rough orientation only, since some applications provided certain features much earlier (as an example, Microsoft Reader used subpixel and Y-direction ClearType already in Windows 2000). Similarly, updates to a given framework might include improved hinting support.</p>

+<p>Color and Gray ClearType are the two available variants of &lsquo;Y-direction ClearType&rsquo;, meaning grayscale rasterization along the Y-direction; the name used in the TrueType specification for this feature is &lsquo;symmetric smoothing&rsquo;. &lsquo;Classic ClearType&rsquo; is the original algorithm used before introducing a modified version in Win&nbsp;XP. Another name for v1.6's grayscale rendering is &lsquo;font smoothing&rsquo;, and &lsquo;Color ClearType&rsquo; is sometimes also called &lsquo;DWrite ClearType&rsquo;. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called &lsquo;GDI ClearType&rsquo;.</p>
+<p>&lsquo;Normal&rsquo; and &lsquo;high&rsquo; sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. &lsquo;Normal&rsquo; means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, &lsquo;high&rsquo; means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like &lsquo;MIRP&rsquo;. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p>
+<p>Note that &lsquo;Gray ClearType&rsquo; is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit&nbsp;12 (hinting for grayscale), while v2.1 returns bits&nbsp;13 (hinting for ClearType), 18 (symmetrical smoothing), and&nbsp;19 (Gray ClearType). Also, this mode respects bits 2 and&nbsp;3 for the version&nbsp;1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version&nbsp;0 (bits 0 and&nbsp;1).</p>
+<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p>

+
+<h4>note</h4>
+<p>The values returned are not pointers into the internal structures of the face, but are &lsquo;fresh&rsquo; copies, so that the memory containing them belongs to the calling application. This also enforces the &lsquo;read-only&rsquo; nature of these values, i.e., this function cannot be used to manipulate the face.</p>
+<p>&lsquo;value&rsquo; is a void pointer because the values returned can be of various types.</p>
+<p>If either &lsquo;value&rsquo; is NULL or &lsquo;value_len&rsquo; is too small, just the required memory size for the requested entry is returned.</p>
+<p>The &lsquo;idx&rsquo; parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.</p>
+<p>PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).</p>
+<p>IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.</p>
+<p>If the font's format is not PostScript-based, this function returns the &lsquo;FT_Err_Invalid_Argument&rsquo; error code.</p>

+<p>The &lsquo;CreateFont&rsquo; documentation says: The FT_WinFNT_ID_OEM value specifies a character set that is operating-system dependent.</p>

+How to prepare a new release
+----------------------------
+
+. include/freetype/freetype.h:  Update FREETYPE_MAJOR, FREETYPE_MINOR,
+  and FREETYPE_PATCH.
+
+. Update version numbers in all files where necessary (for example, do
+  a grep for both `2.3.1' and `231' for release 2.3.1).
+
+. builds/unix/configure.raw: Update `version_info'.
+
+. docs/CHANGES: Document differences to last release.
+
+. README: Update.
+
+. docs/VERSIONS.TXT: Document changed `version_info'.
+
+. ChangeLog:   Announce  new  release   (both  in  the  freetype2  and
+  freetype2-demos modules).
+
+. Clone the git archive to another directory with
+
+    git clone -l -s . ../freetype2.test
+
+  or something like this and run
+
+    make distclean; make devel; make
+    make distclean; make devel; make multi
+    make distclean; make devel CC=g++; make CC=g++
+    make distclean; make devel CC=g++; make multi CC=g++
+
+    sh autogen.sh
+    make distclean; ./configure; make
+    make distclean; ./configure CC=g++; make
+
+  in the cloned repository to test compilation with both gcc and g++.
+
+. Test C++ compilation  for freetype2-demos too  (using `git clone' as
+  above).
+
+. Run  src/tools/chktrcmp.py  and check  that there  are no  undefined
+  trace_XXXX macros.
+
+. After pushing the new release,  tag the git repositories (freetype2,
+  freetype2-demos) with
+
+    git tag VER-<version> -m "" -u <committer>
+
+  and push the tags with
+
+    git push --tags
+
+. Check with
+
+    git clean -ndx
+
+  that the git directory is really clean  (and remove extraneous files
+  if necessary).
+
+. Say `make  dist' in both the  freetype2 and freetype2-demos  modules
+  to generate the .tar.gz, .tar.bz2, and .zip files.
+
+. Create     the     doc    bundles    (freetype-doc-<version>.tar.gz,
+  freetype-doc-<version>.tar.bz2,    ftdoc<version>.zip).    This   is
+  everything in
+
+    <freetype-web git repository>/freetype2/docs
+
+  except the `reference' subdirectory.   Do *not* use option `-l' from
+  zip!
+
+. Run the following script (with updated `$VERSION', `$SAVANNAH_USER',
+  and $SOURCEFORGE_USER  variables) to sign and upload the  bundles to
+  both Savannah and SourceForge.  The signing code has been taken from
+  the `gnupload' script (part of the automake bundle).

+   *     2. If no embedded bitmap is searched or found, FreeType looks for a
+   *        scalable outline.  If one is found, it is loaded from the font
+   *        file, scaled to device pixels, then `hinted' to the pixel grid
+   *        in order to optimize it.  The outline data can be accessed from
+   *        the glyph slot (see note below).
+   *
+   *     Note that by default, the glyph loader doesn't render outlines into
+   *     bitmaps.  The following flags are used to modify this default
+   *     behaviour to more specific and useful cases.
+   *
+   *   FT_LOAD_NO_SCALE ::
+   *     Don't scale the loaded outline glyph but keep it in font units.
+   *
+   *     This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
+   *     unsets @FT_LOAD_RENDER.
+   *
+   *     If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
+   *     FT_LOAD_NO_SCALE usually yields meaningless outlines because the
+   *     subglyphs must be scaled and positioned with hinting instructions.
+   *     This can be solved by loading the font without FT_LOAD_NO_SCALE and
+   *     setting the character size to `font->units_per_EM'.
+   *
+   *   FT_LOAD_NO_HINTING ::
+   *     Disable hinting.  This generally generates `blurrier' bitmap glyphs
+   *     when the glyph are rendered in any of the anti-aliased modes.  See
+   *     also the note below.
+   *
+   *     This flag is implied by @FT_LOAD_NO_SCALE.
+   *
+   *   FT_LOAD_RENDER ::
+   *     Call @FT_Render_Glyph after the glyph is loaded.  By default, the
+   *     glyph is rendered in @FT_RENDER_MODE_NORMAL mode.  This can be
+   *     overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
+   *
+   *     This flag is unset by @FT_LOAD_NO_SCALE.
+   *
+   *   FT_LOAD_NO_BITMAP ::
+   *     Ignore bitmap strikes when loading.  Bitmap-only fonts ignore this
+   *     flag.
+   *
+   *     @FT_LOAD_NO_SCALE always sets this flag.
+   *
+   *   FT_LOAD_VERTICAL_LAYOUT ::
+   *     Load the glyph for vertical text layout.  In particular, the
+   *     `advance' value in the @FT_GlyphSlotRec structure is set to the
+   *     `vertAdvance' value of the `metrics' field.
+   *
+   *     In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
+   *     this flag currently.  Reason is that in this case vertical metrics
+   *     get synthesized, and those values are not always consistent across
+   *     various font formats.
+   *
+   *   FT_LOAD_FORCE_AUTOHINT ::
+   *     Indicates that the auto-hinter is preferred over the font's native
+   *     hinter.  See also the note below.
+   *
+   *   FT_LOAD_PEDANTIC ::
+   *     Indicates that the font driver should perform pedantic verifications
+   *     during glyph loading.  This is mostly used to detect broken glyphs
+   *     in fonts.  By default, FreeType tries to handle broken fonts also.
+   *
+   *     In particular, errors from the TrueType bytecode engine are not
+   *     passed to the application if this flag is not set; this might
+   *     result in partially hinted or distorted glyphs in case a glyph's
+   *     bytecode is buggy.
+   *
+   *   FT_LOAD_NO_RECURSE ::
+   *     Indicate that the font driver should not load composite glyphs
+   *     recursively.  Instead, it should set the `num_subglyph' and
+   *     `subglyphs' values of the glyph slot accordingly, and set
+   *     `glyph->format' to @FT_GLYPH_FORMAT_COMPOSITE.  The description of
+   *     subglyphs can then be accessed with @FT_Get_SubGlyph_Info.
+   *
+   *     This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
+   *
+   *   FT_LOAD_IGNORE_TRANSFORM ::
+   *     Indicates that the transform matrix set by @FT_Set_Transform should
+   *     be ignored.
+   *
+   *   FT_LOAD_MONOCHROME ::
+   *     This flag is used with @FT_LOAD_RENDER to indicate that you want to
+   *     render an outline glyph to a 1-bit monochrome bitmap glyph, with
+   *     8~pixels packed into each byte of the bitmap data.
+   *
+   *     Note that this has no effect on the hinting algorithm used.  You
+   *     should rather use @FT_LOAD_TARGET_MONO so that the
+   *     monochrome-optimized hinting algorithm is used.
+   *
+   *   FT_LOAD_LINEAR_DESIGN ::
+   *     Indicates that the `linearHoriAdvance' and `linearVertAdvance'
+   *     fields of @FT_GlyphSlotRec should be kept in font units.  See
+   *     @FT_GlyphSlotRec for details.
+   *
+   *   FT_LOAD_NO_AUTOHINT ::
+   *     Disable auto-hinter.  See also the note below.
+   *
+   *   FT_LOAD_COLOR ::
+   *     This flag is used to request loading of color embedded-bitmap
+   *     images.  The resulting color bitmaps, if available, will have the
+   *     @FT_PIXEL_MODE_BGRA format.  When the flag is not used and color
+   *     bitmaps are found, they will be converted to 256-level gray
+   *     bitmaps transparently.  Those bitmaps will be in the
+   *     @FT_PIXEL_MODE_GRAY format.
+   *
+   *   FT_LOAD_COMPUTE_METRICS ::
+   *     This flag sets computing glyph metrics without the use of bundled
+   *     metrics tables (for example, the `hdmx' table in TrueType fonts).
+   *     Well-behaving fonts have optimized bundled metrics and these should
+   *     be used.  This flag is mainly used by font validating or font
+   *     editing applications, which need to ignore, verify, or edit those
+   *     tables.
+   *
+   *     Currently, this flag is only implemented for TrueType fonts.
+   *
+   *   FT_LOAD_BITMAP_METRICS_ONLY ::
+   *     This flag is used to request loading of the metrics and bitmap
+   *     image information of a (possibly embedded) bitmap glyph without
+   *     allocating or copying the bitmap image data itself.  No effect if
+   *     the target glyph is not a bitmap image.
+   *
+   *     This flag unsets @FT_LOAD_RENDER.
+   *
+   *   FT_LOAD_CROP_BITMAP ::
+   *     Ignored.  Deprecated.
+   *
+   *   FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
+   *     Ignored.  Deprecated.
+   *
+   * @note:
+   *   By default, hinting is enabled and the font's native hinter (see
+   *   @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter.  You can
+   *   disable hinting by setting @FT_LOAD_NO_HINTING or change the
+   *   precedence by setting @FT_LOAD_FORCE_AUTOHINT.  You can also set
+   *   @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
+   *   used at all.
+   *
+   *   See the description of @FT_FACE_FLAG_TRICKY for a special exception
+   *   (affecting only a handful of Asian fonts).
+   *
+   *   Besides deciding which hinter to use, you can also decide which
+   *   hinting algorithm to use.  See @FT_LOAD_TARGET_XXX for details.
+   *
+   *   Note that the auto-hinter needs a valid Unicode cmap (either a native
+   *   one or synthesized by FreeType) for producing correct results.  If a
+   *   font provides an incorrect mapping (for example, assigning the
+   *   character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
+   *   mathematical integral sign), the auto-hinter might produce useless
+   *   results.

+   *
+   * @enum:
+   *   FT_LOAD_TARGET_XXX
+   *
+   * @description:
+   *   A list of values that are used to select a specific hinting algorithm
+   *   to use by the hinter.  You should OR one of these values to your
+   *   `load_flags' when calling @FT_Load_Glyph.
+   *
+   *   Note that font's native hinters may ignore the hinting algorithm you
+   *   have specified (e.g., the TrueType bytecode interpreter).  You can set
+   *   @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
+   *
+   * @values:
+   *   FT_LOAD_TARGET_NORMAL ::
+   *     This corresponds to the default hinting algorithm, optimized for
+   *     standard gray-level rendering.  For monochrome output, use
+   *     @FT_LOAD_TARGET_MONO instead.
+   *
+   *   FT_LOAD_TARGET_LIGHT ::
+   *     A lighter hinting algorithm for gray-level modes.  Many generated
+   *     glyphs are fuzzier but better resemble their original shape.  This
+   *     is achieved by snapping glyphs to the pixel grid only vertically
+   *     (Y-axis), as is done by Microsoft's ClearType and Adobe's
+   *     proprietary font renderer.  This preserves inter-glyph spacing in
+   *     horizontal text.  The snapping is done either by the native font
+   *     driver if the driver itself and the font support it or by the
+   *     auto-hinter.
+   *
+   *   FT_LOAD_TARGET_MONO ::
+   *     Strong hinting algorithm that should only be used for monochrome
+   *     output.  The result is probably unpleasant if the glyph is rendered
+   *     in non-monochrome modes.
+   *
+   *   FT_LOAD_TARGET_LCD ::
+   *     A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
+   *     decimated LCD displays.
+   *
+   *   FT_LOAD_TARGET_LCD_V ::
+   *     A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
+   *     decimated LCD displays.
+   *
+   * @note:
+   *   You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
+   *   `load_flags'.  They can't be ORed.
+   *
+   *   If @FT_LOAD_RENDER is also set, the glyph is rendered in the
+   *   corresponding mode (i.e., the mode that matches the used algorithm
+   *   best).  An exception is FT_LOAD_TARGET_MONO since it implies
+   *   @FT_LOAD_MONOCHROME.
+   *
+   *   You can use a hinting algorithm that doesn't correspond to the same
+   *   rendering mode.  As an example, it is possible to use the `light'
+   *   hinting algorithm and have the results rendered in horizontal LCD
+   *   pixel mode, with code like
+   *
+   *     {
+   *       FT_Load_Glyph( face, glyph_index,
+   *                      load_flags | FT_LOAD_TARGET_LIGHT );
+   *
+   *       FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );

+   * @description:
+   *   *Experimental* *only*
+   *
+   *   The auto-hinter provides various script modules to hint glyphs.
+   *   Examples of supported scripts are Latin or CJK.  Before a glyph is
+   *   auto-hinted, the Unicode character map of the font gets examined, and
+   *   the script is then determined based on Unicode character ranges, see
+   *   below.
+   *
+   *   OpenType fonts, however, often provide much more glyphs than
+   *   character codes (small caps, superscripts, ligatures, swashes, etc.),
+   *   to be controlled by so-called `features'.  Handling OpenType features
+   *   can be quite complicated and thus needs a separate library on top of
+   *   FreeType.
+   *
+   *   The mapping between glyph indices and scripts (in the auto-hinter
+   *   sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
+   *   array with `num_glyphs' elements, as found in the font's @FT_Face
+   *   structure.  The `glyph-to-script-map' property returns a pointer to
+   *   this array, which can be modified as needed.  Note that the
+   *   modification should happen before the first glyph gets processed by
+   *   the auto-hinter so that the global analysis of the font shapes
+   *   actually uses the modified mapping.
+   *
+   *   The following example code demonstrates how to access it (omitting
+   *   the error handling).
+   *
+   *   {
+   *     FT_Library                library;
+   *     FT_Face                   face;

+   *     // adjust `prop.map' as needed right here

+   * @property:

+   *
+   * @description:
+   *   *Experimental* *only*
+   *
+   *   If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
+   *   activate the warp hinting code in the auto-hinter, this property
+   *   switches warping on and off.
+   *
+   *   Warping only works in `light' auto-hinting mode.  The idea of the
+   *   code is to slightly scale and shift a glyph along the non-hinted
+   *   dimension (which is usually the horizontal axis) so that as much of
+   *   its segments are aligned (more or less) to the grid.  To find out a
+   *   glyph's optimal scaling and shifting value, various parameter
+   *   combinations are tried and scored.
+   *
+   *   By default, warping is off.  The example below shows how to switch on
+   *   warping (omitting the error handling).
+   *
+   *   {
+   *     FT_Library  library;
+   *     FT_Bool     warping = 1;
+   *
+   *
+   *     FT_Init_FreeType( &library );
+   *
+   *     FT_Property_Set( library, "autofitter",
+   *                               "warping", &warping );
+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.
+   *
+   *   This property can be set via the `FREETYPE_PROPERTIES' environment
+   *   variable (using values 1 and 0 for `on' and `off', respectively).
+   *
+   *   The warping code can also change advance widths.  Have a look at the
+   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
+   *   for details on improving inter-glyph distances while rendering.
+   *
+   *   Since warping is a global property of the auto-hinter it is best to
+   *   change its value before rendering any face.  Otherwise, you should
+   *   reload all faces that get auto-hinted in `light' hinting mode.

+   * @description:
+   *   *Experimental* *only,* *requires* *linear* *alpha* *blending* *and*
+   *   *gamma* *correction*
+   *
+   *   Stem darkening emboldens glyphs at smaller sizes to make them more
+   *   readable on common low-DPI screens when using linear alpha blending
+   *   and gamma correction, see @FT_Render_Glyph.  When not using linear
+   *   alpha blending and gamma correction, glyphs will appear heavy and
+   *   fuzzy!
+   *
+   *   Gamma correction essentially lightens fonts since shades of grey are
+   *   shifted to higher pixel values (=~higher brightness) to match the
+   *   original intention to the reality of our screens.  The side-effect is
+   *   that glyphs `thin out'.  Mac OS~X and Adobe's proprietary font
+   *   rendering library implement a counter-measure: stem darkening at
+   *   smaller sizes where shades of gray dominate.  By emboldening a glyph
+   *   slightly in relation to its pixel size, individual pixels get higher
+   *   coverage of filled-in outlines and are therefore `blacker'.  This
+   *   counteracts the `thinning out' of glyphs, making text remain readable
+   *   at smaller sizes.  All glyphs that pass through the auto-hinter will
+   *   be emboldened unless this property is set to TRUE.
+   *
+   *   See the description of the CFF driver for algorithmic details.  Total
+   *   consistency with the CFF driver is currently not achieved because the
+   *   emboldening method differs and glyphs must be scaled down on the
+   *   Y-axis to keep outline points inside their precomputed blue zones.
+   *   The smaller the size (especially 9ppem and down), the higher the loss
+   *   of emboldening versus the CFF driver.
+   *
+   *   This property can be set via the `FREETYPE_PROPERTIES' environment
+   *   variable similar to the CFF driver.

+   *    How to cache face, size, and glyph data with FreeType~2.
+   *
+   * <Description>
+   *   This section describes the FreeType~2 cache sub-system, which is used
+   *   to limit the number of concurrently opened @FT_Face and @FT_Size
+   *   objects, as well as caching information like character maps and glyph
+   *   images while limiting their maximum memory usage.
+   *
+   *   Note that all types and functions begin with the `FTC_' prefix.
+   *
+   *   The cache is highly portable and thus doesn't know anything about the
+   *   fonts installed on your system, or how to access them.  This implies
+   *   the following scheme:
+   *
+   *   First, available or installed font faces are uniquely identified by
+   *   @FTC_FaceID values, provided to the cache by the client.  Note that
+   *   the cache only stores and compares these values, and doesn't try to
+   *   interpret them in any way.
+   *
+   *   Second, the cache calls, only when needed, a client-provided function
+   *   to convert an @FTC_FaceID into a new @FT_Face object.  The latter is
+   *   then completely managed by the cache, including its termination
+   *   through @FT_Done_Face.  To monitor termination of face objects, the
+   *   finalizer callback in the `generic' field of the @FT_Face object can
+   *   be used, which might also be used to store the @FTC_FaceID of the
+   *   face.
+   *
+   *   Clients are free to map face IDs to anything else.  The most simple
+   *   usage is to associate them to a (pathname,face_index) pair that is
+   *   used to call @FT_New_Face.  However, more complex schemes are also
+   *   possible.
+   *
+   *   Note that for the cache to work correctly, the face ID values must be
+   *   *persistent*, which means that the contents they point to should not
+   *   change at runtime, or that their value should not become invalid.
+   *
+   *   If this is unavoidable (e.g., when a font is uninstalled at runtime),
+   *   you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
+   *   the cache get rid of any references to the old @FTC_FaceID it may
+   *   keep internally.  Failure to do so will lead to incorrect behaviour
+   *   or even crashes.
+   *
+   *   To use the cache, start with calling @FTC_Manager_New to create a new
+   *   @FTC_Manager object, which models a single cache instance.  You can
+   *   then look up @FT_Face and @FT_Size objects with
+   *   @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
+   *
+   *   If you want to use the charmap caching, call @FTC_CMapCache_New, then
+   *   later use @FTC_CMapCache_Lookup to perform the equivalent of
+   *   @FT_Get_Char_Index, only much faster.
+   *
+   *   If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
+   *   later use @FTC_ImageCache_Lookup to retrieve the corresponding
+   *   @FT_Glyph objects from the cache.
+   *
+   *   If you need lots of small bitmaps, it is much more memory efficient
+   *   to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup.  This
+   *   returns @FTC_SBitRec structures, which are used to store small
+   *   bitmaps directly.  (A small bitmap is one whose metrics and
+   *   dimensions all fit into 8-bit integers).
+   *
+   *   We hope to also provide a kerning cache in the near future.

+   * @title:
+   *   The CFF driver
+   *
+   * @abstract:
+   *   Controlling the CFF driver module.
+   *
+   * @description:
+   *   While FreeType's CFF driver doesn't expose API functions by itself,
+   *   it is possible to control its behaviour with @FT_Property_Set and
+   *   @FT_Property_Get.  The list below gives the available properties
+   *   together with the necessary macros and structures.
+   *
+   *   The CFF driver's module name is `cff'.
+   *
+   *   *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
+   *
+   *   The rasterizer is positioning horizontal features (e.g., ascender
+   *   height & x-height, or crossbars) on the pixel grid and minimizing the
+   *   amount of antialiasing applied to them, while placing vertical
+   *   features (vertical stems) on the pixel grid without hinting, thus
+   *   representing the stem position and weight accurately.  Sometimes the
+   *   vertical stems may be only partially black.  In this context,
+   *   `antialiasing' means that stems are not positioned exactly on pixel
+   *   borders, causing a fuzzy appearance.
+   *
+   *   There are two principles behind this approach.
+   *
+   *   1) No hinting in the horizontal direction: Unlike `superhinted'
+   *   TrueType, which changes glyph widths to accommodate regular
+   *   inter-glyph spacing, Adobe's approach is `faithful to the design' in
+   *   representing both the glyph width and the inter-glyph spacing
+   *   designed for the font.  This makes the screen display as close as it
+   *   can be to the result one would get with infinite resolution, while
+   *   preserving what is considered the key characteristics of each glyph.
+   *   Note that the distances between unhinted and grid-fitted positions at
+   *   small sizes are comparable to kerning values and thus would be
+   *   noticeable (and distracting) while reading if hinting were applied.
+   *
+   *   One of the reasons to not hint horizontally is antialiasing for LCD
+   *   screens: The pixel geometry of modern displays supplies three
+   *   vertical sub-pixels as the eye moves horizontally across each visible
+   *   pixel.  On devices where we can be certain this characteristic is
+   *   present a rasterizer can take advantage of the sub-pixels to add
+   *   increments of weight.  In Western writing systems this turns out to
+   *   be the more critical direction anyway; the weights and spacing of
+   *   vertical stems (see above) are central to Armenian, Cyrillic, Greek,
+   *   and Latin type designs.  Even when the rasterizer uses greyscale
+   *   antialiasing instead of color (a necessary compromise when one
+   *   doesn't know the screen characteristics), the unhinted vertical
+   *   features preserve the design's weight and spacing much better than
+   *   aliased type would.
+   *
+   *   2) Alignment in the vertical direction: Weights and spacing along the
+   *   y~axis are less critical; what is much more important is the visual
+   *   alignment of related features (like cap-height and x-height).  The
+   *   sense of alignment for these is enhanced by the sharpness of grid-fit
+   *   edges, while the cruder vertical resolution (full pixels instead of
+   *   1/3 pixels) is less of a problem.
+   *
+   *   On the technical side, horizontal alignment zones for ascender,
+   *   x-height, and other important height values (traditionally called
+   *   `blue zones') as defined in the font are positioned independently,
+   *   each being rounded to the nearest pixel edge, taking care of
+   *   overshoot suppression at small sizes, stem darkening, and scaling.
+   *
+   *   Hstems (this is, hint values defined in the font to help align
+   *   horizontal features) that fall within a blue zone are said to be
+   *   `captured' and are aligned to that zone.  Uncaptured stems are moved
+   *   in one of four ways, top edge up or down, bottom edge up or down.
+   *   Unless there are conflicting hstems, the smallest movement is taken
+   *   to minimize distortion.

+   *
+   *   The x~values give the stem width, and the y~values the darkening

+   *
+   *   FT_GASP_DO_GRIDFIT ::
+   *     Grid-fitting and hinting should be performed at the specified ppem.
+   *     This *really* means TrueType bytecode interpretation.  If this bit
+   *     is not set, no hinting gets applied.
+   *
+   *   FT_GASP_DO_GRAY ::
+   *     Anti-aliased rendering should be performed at the specified ppem.
+   *     If not set, do monochrome rendering.
+   *
+   *   FT_GASP_SYMMETRIC_SMOOTHING ::
+   *     If set, smoothing along multiple axes must be used with ClearType.
+   *
+   *   FT_GASP_SYMMETRIC_GRIDFIT ::
+   *     Grid-fitting must be used with ClearType's symmetric smoothing.
+   *
+   * @note:
+   *   The bit-flags `FT_GASP_DO_GRIDFIT' and `FT_GASP_DO_GRAY' are to be
+   *   used for standard font rasterization only.  Independently of that,
+   *   `FT_GASP_SYMMETRIC_SMOOTHING' and `FT_GASP_SYMMETRIC_GRIDFIT' are to
+   *   be used if ClearType is enabled (and `FT_GASP_DO_GRIDFIT' and

+   *   Apart from that, all other tables are loaded normally from the font
+   *   file.  This mode is useful when FreeType is used within another
+   *   engine, e.g., a PostScript Imaging Processor.
+   *
+   *   To enable this mode, you must use @FT_Open_Face, passing an
+   *   @FT_Parameter with the @FT_PARAM_TAG_INCREMENTAL tag and an
+   *   @FT_Incremental_Interface value.  See the comments for
+   *   @FT_Incremental_InterfaceRec for an example.

+   * @title:
+   *   LCD Filtering
+   *
+   * @abstract:
+   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *
+   * @description:
+   *   Subpixel rendering exploits the color-striped structure of LCD
+   *   pixels, increasing the available resolution in the direction of the
+   *   stripe (usually horizontal RGB) by a factor of~3.  Since these
+   *   subpixels are color pixels, using them unfiltered creates severe
+   *   color fringes.  Use the @FT_Library_SetLcdFilter API to specify a
+   *   low-pass filter, which is then applied to subpixel-rendered bitmaps
+   *   generated through @FT_Render_Glyph.  The filter sacrifices some of
+   *   the higher resolution to reduce color fringes, making the glyph image
+   *   slightly blurrier.  Positional improvements will remain.
+   *
+   *   Note that no filter is active by default, and that this function is
+   *   *not* implemented in default builds of the library.  You need to
+   *   #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
+   *   in order to activate it and explicitly call @FT_Library_SetLcdFilter
+   *   to enable it.
+   *
+   *   A filter should have two properties:
+   *
+   *   1) It should be normalized, meaning the sum of the 5~components
+   *      should be 256 (0x100).  It is possible to go above or under this
+   *      target sum, however: going under means tossing out contrast, going
+   *      over means invoking clamping and thereby non-linearities that
+   *      increase contrast somewhat at the expense of greater distortion
+   *      and color-fringing.  Contrast is better enhanced through stem
+   *      darkening.
+   *
+   *   2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
+   *      where a~+ b~=~c.  It distributes the computed coverage for one
+   *      subpixel to all subpixels equally, sacrificing some won resolution
+   *      but drastically reducing color-fringing.  Positioning improvements
+   *      remain!  Note that color-fringing can only really be minimized
+   *      when using a color-balanced filter and alpha-blending the glyph
+   *      onto a surface in linear space; see @FT_Render_Glyph.
+   *
+   *   Regarding the form, a filter can be a `boxy' filter or a `beveled'
+   *   filter.  Boxy filters are sharper but are less forgiving of non-ideal
+   *   gamma curves of a screen (viewing angles!), beveled filters are
+   *   fuzzier but more tolerant.
+   *
+   *   Examples:
+   *
+   *   - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
+   *     normalized.
+   *
+   *   - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
+   *     normalized.
+   *
+   *   - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
+   *     balanced.
+   *
+   *   - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
+   *     balanced.
+   *
+   *   - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
+   *     balanced.
+   *
+   *   - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
+   *     balanced.
+   *
+   *   The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
+   *   @FT_Load_Glyph, and @FT_Load_Char.  It does _not_ affect the output
+   *   of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
+   *
+   *   If this feature is activated, the dimensions of LCD glyph bitmaps are
+   *   either wider or taller than the dimensions of the corresponding
+   *   outline with regard to the pixel grid.  For example, for
+   *   @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
+   *   3~subpixels to the right.  The bitmap offset values are adjusted
+   *   accordingly, so clients shouldn't need to modify their layout and
+   *   glyph positioning code when enabling the filter.
+   *
+   *   It is important to understand that linear alpha blending and gamma
+   *   correction is critical for correctly rendering glyphs onto surfaces
+   *   without artifacts and even more critical when subpixel rendering is
+   *   involved.
+   *
+   *   Each of the 3~alpha values (subpixels) is independently used to blend
+   *   one color channel.  That is, red alpha blends the red channel of the
+   *   text color with the red channel of the background pixel.  The
+   *   distribution of density values by the color-balanced filter assumes
+   *   alpha blending is done in linear space; only then color artifacts
+   *   cancel out.

+   * @enum:
+   *   FT_LcdFilter
+   *
+   * @description:
+   *   A list of values to identify various types of LCD filters.
+   *
+   * @values:
+   *   FT_LCD_FILTER_NONE ::
+   *     Do not perform filtering.  When used with subpixel rendering, this
+   *     results in sometimes severe color fringes.
+   *
+   *   FT_LCD_FILTER_DEFAULT ::
+   *     The default filter reduces color fringes considerably, at the cost
+   *     of a slight blurriness in the output.
+   *
+   *     It is a beveled, normalized, and color-balanced five-tap filter
+   *     that is more forgiving to screens with non-ideal gamma curves and
+   *     viewing angles.  Note that while color-fringing is reduced, it can
+   *     only be minimized by using linear alpha blending and gamma
+   *     correction to render glyphs onto surfaces.  The default filter
+   *     weights are [0x08 0x4D 0x56 0x4D 0x08].
+   *
+   *   FT_LCD_FILTER_LIGHT ::
+   *     The light filter is a variant that is sharper at the cost of
+   *     slightly more color fringes than the default one.
+   *
+   *     It is a boxy, normalized, and color-balanced three-tap filter that
+   *     is less forgiving to screens with non-ideal gamma curves and
+   *     viewing angles.  This filter works best when the rendering system
+   *     uses linear alpha blending and gamma correction to render glyphs
+   *     onto surfaces.  The light filter weights are
+   *     [0x00 0x55 0x56 0x55 0x00].
+   *
+   *   FT_LCD_FILTER_LEGACY ::
+   *     This filter corresponds to the original libXft color filter.  It
+   *     provides high contrast output but can exhibit really bad color
+   *     fringes if glyphs are not extremely well hinted to the pixel grid.
+   *     In other words, it only works well if the TrueType bytecode
+   *     interpreter is enabled *and* high-quality hinted fonts are used.
+   *
+   *     This filter is only provided for comparison purposes, and might be
+   *     disabled or stay unsupported in the future.
+   *
+   *   FT_LCD_FILTER_LEGACY1 ::
+   *     For historical reasons, the FontConfig library returns a different
+   *     enumeration value for legacy LCD filtering.  To make code work that
+   *     (incorrectly) forwards FontConfig's enumeration value to
+   *     @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
+   *     to have another enumeration value, which is completely equal to
+   *     `FT_LCD_FILTER_LEGACY'.
+   *
+   * @since:
+   *   2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)

+  *

+  *
+  *   source :: The source stream.
+  *
+  * @return:
+  *   FreeType error code.  0~means success.
+  *
+  * @note:
+  *   The source stream must be opened _before_ calling this function.
+  *
+  *   Calling the internal function `FT_Stream_Close' on the new stream will
+  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
+  *   objects will be released to the heap.
+  *
+  *   The stream implementation is very basic and resets the decompression
+  *   process each time seeking backwards is needed within the stream
+  *
+  *   In certain builds of the library, LZW compression recognition is
+  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
+  *   This means that if no font driver is capable of handling the raw
+  *   compressed file, the library will try to open a LZW stream from it
+  *   and re-open the face with it.
+  *
+  *   This function may return `FT_Err_Unimplemented_Feature' if your build
+  *   of FreeType was not compiled with LZW support.

+  *
+  *    This can be useful to generate `bordered' glyph, i.e., glyphs
+  *    displayed with a coloured (and anti-aliased) border around their
+  *    shape.

+   * @title:
+   *   The TrueType driver
+   *
+   * @abstract:
+   *   Controlling the TrueType driver module.
+   *
+   * @description:
+   *   While FreeType's TrueType driver doesn't expose API functions by
+   *   itself, it is possible to control its behaviour with @FT_Property_Set
+   *   and @FT_Property_Get.  The following lists the available properties
+   *   together with the necessary macros and structures.
+   *
+   *   The TrueType driver's module name is `truetype'.
+   *
+   *   We start with a list of definitions, kindly provided by Greg
+   *   Hitchcock.
+   *
+   *   _Bi-Level_ _Rendering_
+   *
+   *   Monochromatic rendering, exclusively used in the early days of
+   *   TrueType by both Apple and Microsoft.  Microsoft's GDI interface
+   *   supported hinting of the right-side bearing point, such that the
+   *   advance width could be non-linear.  Most often this was done to
+   *   achieve some level of glyph symmetry.  To enable reasonable
+   *   performance (e.g., not having to run hinting on all glyphs just to
+   *   get the widths) there was a bit in the head table indicating if the
+   *   side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+   *   cache hinting widths across multiple sizes and device aspect ratios.
+   *
+   *   _Font_ _Smoothing_
+   *
+   *   Microsoft's GDI implementation of anti-aliasing.  Not traditional
+   *   anti-aliasing as the outlines were hinted before the sampling.  The
+   *   widths matched the bi-level rendering.
+   *
+   *   _ClearType_ _Rendering_
+   *
+   *   Technique that uses physical subpixels to improve rendering on LCD
+   *   (and other) displays.  Because of the higher resolution, many methods
+   *   of improving symmetry in glyphs through hinting the right-side
+   *   bearing were no longer necessary.  This lead to what GDI calls
+   *   `natural widths' ClearType, see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec21.  Since hinting
+   *   has extra resolution, most non-linearity went away, but it is still
+   *   possible for hints to change the advance widths in this mode.
+   *
+   *   _ClearType_ _Compatible_ _Widths_
+   *
+   *   One of the earliest challenges with ClearType was allowing the
+   *   implementation in GDI to be selected without requiring all UI and
+   *   documents to reflow.  To address this, a compatible method of
+   *   rendering ClearType was added where the font hints are executed once
+   *   to determine the width in bi-level rendering, and then re-run in
+   *   ClearType, with the difference in widths being absorbed in the font
+   *   hints for ClearType (mostly in the white space of hints); see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec20.  Somewhat by
+   *   definition, compatible width ClearType allows for non-linear widths,
+   *   but only when the bi-level version has non-linear widths.
+   *
+   *   _ClearType_ _Subpixel_ _Positioning_
+   *
+   *   One of the nice benefits of ClearType is the ability to more crisply
+   *   display fractional widths; unfortunately, the GDI model of integer
+   *   bitmaps did not support this.  However, the WPF and Direct Write
+   *   frameworks do support fractional widths.  DWrite calls this `natural
+   *   mode', not to be confused with GDI's `natural widths'.  Subpixel
+   *   positioning, in the current implementation of Direct Write,
+   *   unfortunately does not support hinted advance widths, see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec22.  Note that the
+   *   TrueType interpreter fully allows the advance width to be adjusted in
+   *   this mode, just the DWrite client will ignore those changes.
+   *
+   *   _ClearType_ _Backwards_ _Compatibility_
+   *
+   *   This is a set of exceptions made in the TrueType interpreter to
+   *   minimize hinting techniques that were problematic with the extra
+   *   resolution of ClearType; see
+   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+   *   http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+   *   This technique is not to be confused with ClearType compatible
+   *   widths.  ClearType backwards compatibility has no direct impact on
+   *   changing advance widths, but there might be an indirect impact on
+   *   disabling some deltas.  This could be worked around in backwards
+   *   compatibility mode.
+   *
+   *   _Native_ _ClearType_ _Mode_
+   *
+   *   (Not to be confused with `natural widths'.)  This mode removes all
+   *   the exceptions in the TrueType interpreter when running with
+   *   ClearType.  Any issues on widths would still apply, though.

+   * @property:
+   *   interpreter-version
+   *
+   * @description:
+
+   *   Currently, three versions are available, two representing the
+   *   bytecode interpreter with subpixel hinting support (old `Infinality'
+   *   code and new stripped-down and higher performance `minimal' code) and
+   *   one without, respectively.  The default is subpixel support if
+   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+   *   otherwise (since it isn't available then).
+   *
+   *   If subpixel hinting is on, many TrueType bytecode instructions behave
+   *   differently compared to B/W or grayscale rendering (except if `native
+   *   ClearType' is selected by the font).  Microsoft's main idea is to
+   *   render at a much increased horizontal resolution, then sampling down
+   *   the created output to subpixel precision.  However, many older fonts
+   *   are not suited to this and must be specially taken care of by
+   *   applying (hardcoded) tweaks in Microsoft's interpreter.
+   *
+   *   Details on subpixel hinting and some of the necessary tweaks can be
+   *   found in Greg Hitchcock's whitepaper at
+   *   `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'. 
+   *   Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+   *   or 6x5 supersampling) like discussed in the paper.  Depending on the
+   *   chosen interpreter, it simply ignores instructions on vertical stems
+   *   to arrive at very similar results.
+   *
+   *   The following example code demonstrates how to deactivate subpixel
+   *   hinting (omitting the error handling).
+   *
+   *   {
+   *     FT_Library  library;
+   *     FT_Face     face;
+   *     FT_UInt     interpreter_version = TT_INTERPRETER_VERSION_35;
+   *
+   *
+   *     FT_Init_FreeType( &library );
+   *
+   *     FT_Property_Set( library, "truetype",
+   *                               "interpreter-version",
+   *                               &interpreter_version );
+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.
+   *
+   *   This property can be set via the `FREETYPE_PROPERTIES' environment
+   *   variable (using values `35', `38', or `40').

+   * @enum:
+   *   TT_INTERPRETER_VERSION_XXX
+   *
+   * @description:
+   *   A list of constants used for the @interpreter-version property to
+   *   select the hinting engine for Truetype fonts.
+   *
+   *   The numeric value in the constant names represents the version
+   *   number as returned by the `GETINFO' bytecode instruction.
+   *
+   * @values:
+   *   TT_INTERPRETER_VERSION_35 ::
+   *     Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
+   *     Windows~98; only grayscale and B/W rasterizing is supported.
+   *
+   *   TT_INTERPRETER_VERSION_38 ::
+   *     Version~38 corresponds to MS rasterizer v.1.9; it is roughly
+   *     equivalent to the hinting provided by DirectWrite ClearType (as can
+   *     be found, for example, in the Internet Explorer~9 running on
+   *     Windows~7).  It is used in FreeType to select the `Infinality'
+   *     subpixel hinting code.  The code may be removed in a future
+   *     version.
+   *
+   *   TT_INTERPRETER_VERSION_40 ::
+   *     Version~40 corresponds to MS rasterizer v.2.1; it is roughly
+   *     equivalent to the hinting provided by DirectWrite ClearType (as can
+   *     be found, for example, in Microsoft's Edge Browser on Windows~10). 
+   *     It is used in FreeType to select the `minimal' subpixel hinting
+   *     code, a stripped-down and higher performance version of the
+   *     `Infinality' code.
+   *
+   * @note:
+   *   This property controls the behaviour of the bytecode interpreter
+   *   and thus how outlines get hinted.  It does *not* control how glyph
+   *   get rasterized!  In particular, it does not control subpixel color
+   *   filtering.
+   *
+   *   If FreeType has not been compiled with the configuration option
+   *   FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 causes
+   *   an `FT_Err_Unimplemented_Feature' error.
+   *
+   *   Depending on the graphics framework, Microsoft uses different
+   *   bytecode and rendering engines.  As a consequence, the version
+   *   numbers returned by a call to the `GETINFO' bytecode instruction are
+   *   more convoluted than desired.
+   *
+   *   Here are two tables that try to shed some light on the possible
+   *   values for the MS rasterizer engine, together with the additional
+   *   features introduced by it.

+   *
+   *   Color and Gray ClearType are the two available variants of
+   *   `Y-direction ClearType', meaning grayscale rasterization along the
+   *   Y-direction; the name used in the TrueType specification for this
+   *   feature is `symmetric smoothing'.  `Classic ClearType' is the
+   *   original algorithm used before introducing a modified version in
+   *   Win~XP.  Another name for v1.6's grayscale rendering is `font
+   *   smoothing', and `Color ClearType' is sometimes also called `DWrite
+   *   ClearType'.  To differentiate between today's Color ClearType and the
+   *   earlier ClearType variant with B/W rendering along the vertical axis,
+   *   the latter is sometimes called `GDI ClearType'.
+   *
+   *   `Normal' and `high' sampling describe the (virtual) resolution to
+   *   access the rasterized outline after the hinting process.  `Normal'
+   *   means 1 sample per grid line (i.e., B/W).  In the current Microsoft
+   *   implementation, `high' means an extra virtual resolution of 16x16 (or
+   *   16x1) grid lines per pixel for bytecode instructions like `MIRP'.
+   *   After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+   *   lines for color filtering if Color ClearType is activated.
+   *
+   *   Note that `Gray ClearType' is essentially the same as v1.6's
+   *   grayscale rendering.  However, the GETINFO instruction handles it
+   *   differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+   *   returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+   *   and~19 (Gray ClearType).  Also, this mode respects bits 2 and~3 for
+   *   the version~1 gasp table exclusively (like Color ClearType), while
+   *   v1.6 only respects the values of version~0 (bits 0 and~1).
+   *
+   *   Keep in mind that the features of the above interpreter versions
+   *   might not map exactly to FreeType features or behavior because it is
+   *   a fundamentally different library with different internals.

+   *   FT_WinFNT_ID_XXX
+   *
+   * @description:
+   *   A list of valid values for the `charset' byte in
+   *   @FT_WinFNT_HeaderRec.  Exact mapping tables for the various cpXXXX
+   *   encodings (except for cp1361) can be found at
+   *   ftp://ftp.unicode.org/Public in the MAPPINGS/VENDORS/MICSFT/WINDOWS
+   *   subdirectory.  cp1361 is roughly a superset of
+   *   MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
+   *
+   * @values:
+   *   FT_WinFNT_ID_DEFAULT ::
+   *     This is used for font enumeration and font creation as a
+   *     `don't care' value.  Valid font files don't contain this value.
+   *     When querying for information about the character set of the font
+   *     that is currently selected into a specified device context, this
+   *     return value (of the related Windows API) simply denotes failure.
+   *
+   *   FT_WinFNT_ID_SYMBOL ::
+   *     There is no known mapping table available.
+   *
+   *   FT_WinFNT_ID_MAC ::
+   *     Mac Roman encoding.
+   *
+   *   FT_WinFNT_ID_OEM ::
+   *     From Michael Pöttgen <michael@poettgen.de>:
+   *
+   *       The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
+   *       is used for the charset of vector fonts, like `modern.fon',
+   *       `roman.fon', and `script.fon' on Windows.
+   *
+   *       The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
+   *       specifies a character set that is operating-system dependent.
+   *
+   *       The `IFIMETRICS' documentation from the `Windows Driver
+   *       Development Kit' says: This font supports an OEM-specific
+   *       character set.  The OEM character set is system dependent.
+   *
+   *       In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
+   *       second default codepage that most international versions of
+   *       Windows have.  It is one of the OEM codepages from
+   *
+   *         https://msdn.microsoft.com/en-us/goglobal/bb964655,
+   *
+   *       and is used for the `DOS boxes', to support legacy applications.
+   *       A German Windows version for example usually uses ANSI codepage
+   *       1252 and OEM codepage 850.
+   *
+   *   FT_WinFNT_ID_CP874 ::
+   *     A superset of Thai TIS 620 and ISO 8859-11.
+   *
+   *   FT_WinFNT_ID_CP932 ::
+   *     A superset of Japanese Shift-JIS (with minor deviations).
+   *
+   *   FT_WinFNT_ID_CP936 ::
+   *     A superset of simplified Chinese GB 2312-1980 (with different
+   *     ordering and minor deviations).
+   *
+   *   FT_WinFNT_ID_CP949 ::
+   *     A superset of Korean Hangul KS~C 5601-1987 (with different
+   *     ordering and minor deviations).
+   *
+   *   FT_WinFNT_ID_CP950 ::
+   *     A superset of traditional Chinese Big~5 ETen (with different
+   *     ordering and minor deviations).
+   *
+   *   FT_WinFNT_ID_CP1250 ::
+   *     A superset of East European ISO 8859-2 (with slightly different
+   *     ordering).
+   *
+   *   FT_WinFNT_ID_CP1251 ::
+   *     A superset of Russian ISO 8859-5 (with different ordering).
+   *
+   *   FT_WinFNT_ID_CP1252 ::
+   *     ANSI encoding.  A superset of ISO 8859-1.
+   *
+   *   FT_WinFNT_ID_CP1253 ::
+   *     A superset of Greek ISO 8859-7 (with minor modifications).
+   *
+   *   FT_WinFNT_ID_CP1254 ::
+   *     A superset of Turkish ISO 8859-9.
+   *
+   *   FT_WinFNT_ID_CP1255 ::
+   *     A superset of Hebrew ISO 8859-8 (with some modifications).
+   *
+   *   FT_WinFNT_ID_CP1256 ::
+   *     A superset of Arabic ISO 8859-6 (with different ordering).
+   *
+   *   FT_WinFNT_ID_CP1257 ::
+   *     A superset of Baltic ISO 8859-13 (with some deviations).
+   *
+   *   FT_WinFNT_ID_CP1258 ::
+   *     For Vietnamese.  This encoding doesn't cover all necessary
+   *     characters.
+   *
+   *   FT_WinFNT_ID_CP1361 ::
+   *     Korean (Johab).

+   *
+   * @input:
+   *    face ::
+   *       PostScript face handle.
+   *
+   *    key ::
+   *       An enumeration value representing the dictionary key to retrieve.
+   *
+   *    idx ::
+   *       For array values, this specifies the index to be returned.
+   *
+   *    value ::
+   *       A pointer to memory into which to write the value.
+   *
+   *    valen_len ::
+   *       The size, in bytes, of the memory supplied for the value.
+   *
+   * @output:
+   *    value ::
+   *       The value matching the above key, if it exists.
+   *
+   * @return:
+   *    The amount of memory (in bytes) required to hold the requested
+   *    value (if it exists, -1 otherwise).
+   *
+   * @note:
+   *    The values returned are not pointers into the internal structures of
+   *    the face, but are `fresh' copies, so that the memory containing them
+   *    belongs to the calling application.  This also enforces the
+   *    `read-only' nature of these values, i.e., this function cannot be
+   *    used to manipulate the face.
+   *
+   *    `value' is a void pointer because the values returned can be of
+   *    various types.
+   *
+   *    If either `value' is NULL or `value_len' is too small, just the
+   *    required memory size for the requested entry is returned.
+   *
+   *    The `idx' parameter is used, not only to retrieve elements of, for
+   *    example, the FontMatrix or FontBBox, but also to retrieve name keys
+   *    from the CharStrings dictionary, and the charstrings themselves.  It
+   *    is ignored for atomic values.
+   *
+   *    PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000.  To
+   *    get the value as in the font stream, you need to divide by
+   *    65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
+   *
+   *    IMPORTANT: Only key/value pairs read by the FreeType interpreter can
+   *    be retrieved.  So, for example, PostScript procedures such as NP,
+   *    ND, and RD are not available.  Arbitrary keys are, obviously, not be
+   *    available either.
+   *
+   *    If the font's format is not PostScript-based, this function returns
+   *    the `FT_Err_Invalid_Argument' error code.

+
+
+// This file contains data specific to blue zones.  It gets processed by
+// a script to simulate `jagged arrays', with enumeration values holding
+// offsets into the arrays.
+//
+// The format of the file is rather simple:  A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template.  The script then fills the corresponding templates
+// (indicated by `@' characters around the name).
+//
+// A section contains one or more data records.  Each data record consists
+// of two or more lines.  The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters or character clusters (for example, representing
+//   Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
+//   quotes, using C syntax, where the elements are separated by spaces.
+//   There can be only one string per line, thus the starting and ending
+//   double quote must be the first and last character in the line,
+//   respectively, ignoring whitespace before and after the string.  If
+//   there are multiple strings (in multiple lines), they are concatenated
+//   to a single string.  In the output, a string gets represented as a
+//   series of singles bytes, followed by a zero byte.  The enumeration
+//   values simply hold byte offsets to the start of the corresponding
+//   strings.
+//
+//   For strings, the `maximum' template holds the maximum number of
+//   non-space characters in all strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+//   which can span multiple lines.  The opening brace of a block must be
+//   the first character of a line (ignoring whitespace), and the closing
+//   brace the last (ignoring whitespace also).  The script appends a comma
+//   character after each block and counts the number of blocks to set the
+//   enumeration values.
+//
+//   For data blocks, the `maximum' template holds the maximum number of
+//   array elements.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed.  A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array.  Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum
+// values; this essentially means that the maximum values can easily be too
+// large.  Given that the purpose of those values is to create local
+// fixed-size arrays at compile time for further processing of the blue zone
+// data, this isn't a problem.  Note the final zero byte of a string is not
+// counted.  Note also that the count holds the number of UTF-8 encoded
+// characters, not bytes.

+// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
+//
+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored).  All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum.  The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively.  Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// Some scripts like Khmer need character composition to get all necessary
+// blue zones, since Unicode only provides an abstract data model that
+// doesn't represent all possible glyph shapes.  For such character
+// clusters, the HarfBuzz library is used to convert them into the
+// corresponding glyphs.  The largest glyph element (where `largest' can be
+// either `largest ascender' or `largest descender') then defines the
+// corresponding flat or round extremum.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   LATIN_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters for computing the blue zone's reference and overshoot
+//     values.
+//
+//     If not set, take the minimum values.
+//
+//     Mutually exclusive with `LATIN_SUB_TOP'.
+//
+//   LATIN_SUB_TOP
+//     For all glyphs of a character cluster, compute the maximum flat
+//     and round coordinate values of each component, then take the
+//     smallest of the maximum values.  The idea is to get the top of
+//     subscript glyphs, as used in Khmer, for example.  Note that
+//     this mechanism doesn't work for ordinary ligatures.
+//
+//     This flags indicates a secondary blue zone: It gets removed if
+//     there is a non-LATIN_SUB_TOP blue zone at the same coordinate
+//     value (after scaling).
+//
+//     Mutually exclusive with `LATIN_TOP'.
+//
+//   LATIN_NEUTRAL
+//     Ignore round extrema and define the blue zone with flat values only.
+//     Both top and bottom of contours can match.  This is useful for
+//     scripts like Devanagari where vowel signs attach to the base
+//     character and are implemented as components of composite glyphs.
+//
+//     If not set, both round and flat extrema are taken into account.
+//     Additionally, only the top or the bottom of a contour can match,
+//     depending on the LATIN_TOP flag.
+//
+//     Neutral blue zones should always follow non-neutral blue zones.
+//
+//   LATIN_X_HEIGHT
+//     Scale all glyphs vertically from the corresponding script to make the
+//     reference line of this blue zone align on the grid.  The scaling
+//     takes place before all other blue zones get aligned to the grid.
+//     Only one blue character string of a script style can have this flag.
+//
+//   LATIN_LONG
+//     Apply an additional constraint for blue zone values: Don't
+//     necessarily use the extremum as-is but a segment of the topmost (or
+//     bottommost) contour that is longer than a heuristic threshold, and
+//     which is not too far away vertically from the real extremum.  This
+//     ensures that small bumps in the outline are ignored (for example, the
+//     `vertical serifs' found in many Hebrew glyph designs).
+//
+//     The segment must be at least EM/25 font units long, and the distance
+//     to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified.  Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value
+// (everything separated by space characters).  The blue zone is then set up
+// by the mean values of all reference values and all overshoot values,
+// respectively.  Both horizontal and vertical blue zones (i.e., adjusting
+// vertical and horizontal coordinate values, respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+//   CJK_TOP
+//     Take the maximum flat and round coordinate values of the blue string
+//     characters.  If not set, take the minimum values.
+//
+//   CJK_RIGHT
+//     A synonym for CJK_TOP.  If CJK_HORIZ is set, this flag indicates the
+//     right blue zone, taking horizontal maximum values.
+//
+//   CJK_HORIZ
+//     Define a blue zone for horizontal hinting (i.e., vertical blue
+//     zones).  If not set, this is a blue zone for vertical hinting.

+   *    Real-Time Grid Fitting of Typographic Outlines

+   *
+   *  Segments
+   *
+   *    `af_{cjk,latin,...}_hints_compute_segments' are the functions to
+   *    find segments in an outline.
+   *
+   *    A segment is a series of at least two consecutive points that are
+   *    approximately aligned along a coordinate axis.  The analysis to do
+   *    so is specific to a writing system.
+   *
+   *
+   *  Edges
+   *
+   *    `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
+   *    edges.
+   *
+   *    As soon as segments are defined, the auto-hinter groups them into
+   *    edges.  An edge corresponds to a single position on the main
+   *    dimension that collects one or more segments (allowing for a small
+   *    threshold).
+   *
+   *    As an example, the `latin' writing system first tries to grid-fit
+   *    edges, then to align segments on the edges unless it detects that
+   *    they form a serif.

+   *
+   *  Stems
+   *
+   *    Stems are detected by `af_{cjk,latin,...}_hint_edges'.
+   *
+   *    Segments need to be `linked' to other ones in order to detect stems.
+   *    A stem is made of two segments that face each other in opposite
+   *    directions and that are sufficiently close to each other.  Using
+   *    vocabulary from the TrueType specification, stem segments form a
+   *    `black distance'.
+   *
+   *    In the above ASCII drawing, the horizontal segments are BC, DE, and
+   *    FG; the vertical segments are AB, CD, EF, and GH.
+   *
+   *    Each segment has at most one `best' candidate to form a black
+   *    distance, or no candidate at all.  Notice that two distinct segments
+   *    can have the same candidate, which frequently means a serif.
+   *
+   *    A stem is recognized by the following condition:
+   *
+   *      best segment_1 = segment_2 && best segment_2 = segment_1
+   *
+   *    The best candidate is stored in field `link' in structure
+   *    `AF_Segment'.
+   *
+   *    In the above ASCII drawing, the best candidate for both AB and CD is
+   *    GH, while the best candidate for GH is AB.  Similarly, the best
+   *    candidate for EF and GH is AB, while the best candidate for AB is
+   *    GH.
+   *
+   *    The detection and handling of stems is dependent on the writing
+   *    system.
+   *
+   *
+   *  Serifs
+   *
+   *    Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
+   *
+   *    In comparison to a stem, a serif (as handled by the auto-hinter
+   *    module that takes care of the `latin' writing system) has
+   *
+   *      best segment_1 = segment_2 && best segment_2 != segment_1
+   *
+   *    where segment_1 corresponds to the serif segment (CD and EF in the
+   *    above ASCII drawing).
+   *
+   *    The best candidate is stored in field `serif' in structure
+   *    `AF_Segment' (and `link' is set to NULL).
+   *
+   *
+   *  Touched points
+   *
+   *    A point is called `touched' if it has been processed somehow by the
+   *    auto-hinter.  It basically means that it shouldn't be moved again
+   *    (or moved only under certain constraints to preserve the already
+   *    applied processing).
+   *
+   *
+   *  Flat and round segments
+   *
+   *    Segments are `round' or `flat', depending on the series of points
+   *    that define them.  A segment is round if the next and previous point
+   *    of an extremum (which can be either a single point or sequence of
+   *    points) are both conic or cubic control points.  Otherwise, a
+   *    segment with an extremum is flat.
+   *
+   *
+   *  Strong Points
+   *
+   *    Experience has shown that points not part of an edge need to be
+   *    interpolated linearly between their two closest edges, even if these
+   *    are not part of the contour of those particular points.  Typical
+   *    candidates for this are
+   *
+   *    - angle points (i.e., points where the `in' and `out' direction
+   *      differ greatly)
+   *
+   *    - inflection points (i.e., where the `in' and `out' angles are the
+   *      same, but the curvature changes sign) [currently, such points
+   *      aren't handled specially in the auto-hinter]
+   *
+   *    `af_glyph_hints_align_strong_points' is the function that takes
+   *    care of such situations; it is equivalent to the TrueType `IP'
+   *    hinting instruction.
+   *
+   *
+   *  Weak Points
+   *
+   *    Other points in the outline must be interpolated using the
+   *    coordinates of their previous and next unfitted contour neighbours.
+   *    These are called `weak points' and are touched by the function
+   *    `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
+   *    hinting instruction.  Typical candidates are control points and
+   *    points on the contour without a major direction.
+   *
+   *    The major effect is to reduce possible distortion caused by
+   *    alignment of edges and strong points, thus weak points are processed
+   *    after strong points.

+   *   - Next comes the default style, using the character ranges as defined
+   *     below.  This also assigns properties.
+   *
+   *   Note that there also exist fallback scripts, mainly covering
+   *   superscript and subscript glyphs of a script that are not present as
+   *   OpenType features.  Fallback scripts are defined below, also

+     * agnostic of OpenType features after the feature analysis has been
+     * completed: The engine then simply receives a glyph index and returns a
+     * hinted and usually rendered glyph.
+     *
+     * Consider the superscript feature of font `pala.ttf': Some of the
+     * glyphs are `real', this is, they have a zero vertical offset, but
+     * most of them are small caps glyphs shifted up to the superscript
+     * position (this is, the `sups' feature is present in both the GSUB and
+     * GPOS tables).  The code for blue zones computation actually uses a
+     * feature's y offset so that the `real' glyphs get correct hints.  But
+     * later on it is impossible to decide whether a glyph index belongs to,
+     * say, the small caps or superscript feature.
+     *
+     * For this reason, we don't assign a style to a glyph if the current
+     * feature covers the glyph in both the GSUB and the GPOS tables.  This
+     * is quite a broad condition, assuming that
+     *
+     *   (a) glyphs that get used in multiple features are present in a
+     *       feature without vertical shift,
+     *
+     * and
+     *
+     *   (b) a feature's GPOS data really moves the glyph vertically.
+     *
+     * Not fulfilling condition (a) makes a font larger; it would also
+     * reduce the number of glyphs that could be addressed directly without
+     * using OpenType features, so this assumption is rather strong.
+     *
+     * Condition (b) is much weaker, and there might be glyphs which get
+     * missed.  However, the OpenType features we are going to handle are
+     * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+     * directly get the necessary information from the GPOS table.  A
+     * possible solution might be to directly parse the GPOS table to find
+     * out whether a glyph gets shifted vertically, but this is something I
+     * would like to avoid if not really necessary.
+     *
+     * Note that we don't follow this logic for the default coverage.
+     * Complex scripts like Devanagari have mandatory GPOS features to
+     * position many glyph elements, using mark-to-base or mark-to-ligature
+     * tables; the number of glyphs missed due to condition (b) would be far

+   *  Usually, a font contains more glyphs than can be addressed by its

+   *
+   *  In the PostScript font world, encoding vectors specific to a given
+   *  task are used to select such glyphs, and these glyphs can be often
+   *  recognized by having a suffix in its glyph names.  For example, a
+   *  superscript glyph `A' might be called `A.sup'.  Unfortunately, this
+   *  naming scheme is not standardized and thus unusable for us.
+   *
+   *  In the OpenType world, a better solution was invented, namely
+   *  `features', which cleanly separate a character's input encoding from
+   *  the corresponding glyph's appearance, and which don't use glyph names
+   *  at all.  For our purposes, and slightly generalized, an OpenType
+   *  feature is a name of a mapping that maps character codes to
+   *  non-standard glyph indices (features get used for other things also).
+   *  For example, the `sups' feature provides superscript glyphs, thus
+   *  mapping character codes like `A' or `B' to superscript glyph
+   *  representation forms.  How this mapping happens is completely
+   *  uninteresting to us.
+   *
+   *  For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+   *  feature collected in a set (as listed below) that can be hinted
+   *  together.  To continue the above example, superscript glyphs must not
+   *  be hinted together with normal glyphs because the blue zones
+   *  completely differ.
+   *
+   *  Note that FreeType itself doesn't compute coverages; it only provides
+   *  the glyphs addressable by the default Unicode character map.  Instead,
+   *  we use the HarfBuzz library (if available), which has many functions
+   *  exactly for this purpose.
+   *
+   *  AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+   *  listed separately (including the glyphs addressable by the character
+   *  map).  In case HarfBuzz isn't available, it exactly covers the glyphs
+   *  addressable by the character map.

+    Notes
+
+    Mac suitcase files can (and often do!) contain multiple fonts.  To
+    support this I use the face_index argument of FT_(Open|New)_Face()
+    functions, and pretend the suitcase file is a collection.
+
+    Warning: fbit and NFNT bitmap resources are not supported yet.  In old
+    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+    resources instead of the `bdat' table in the sfnt resource.  Therefore,
+    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+    resource is unavailable at present.
+
+    The Mac FOND support works roughly like this:
+
+    - Check whether the offered stream points to a Mac suitcase file.  This
+      is done by checking the file type: it has to be 'FFIL' or 'tfil'.  The
+      stream that gets passed to our init_face() routine is a stdio stream,
+      which isn't usable for us, since the FOND resources live in the
+      resource fork.  So we just grab the stream->pathname field.
+
+    - Read the FOND resource into memory, then check whether there is a
+      TrueType font and/or(!) a Type 1 font available.
+
+    - If there is a Type 1 font available (as a separate `LWFN' file), read
+      its data into memory, massage it slightly so it becomes PFB data, wrap
+      it into a memory stream, load the Type 1 driver and delegate the rest
+      of the work to it by calling FT_Open_Face().  (XXX TODO: after this
+      has been done, the kerning data from the FOND resource should be
+      appended to the face: On the Mac there are usually no AFM files
+      available.  However, this is tricky since we need to map Mac char
+      codes to ps glyph names to glyph ID's...)
+
+    - If there is a TrueType font (an `sfnt' resource), read it into memory,
+      wrap it into a memory stream, load the TrueType driver and delegate
+      the rest of the work to it, by calling FT_Open_Face().
+
+    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+      itself, even though it doesn't contains `POST' resources.  To handle
+      this special case without opening the file an extra time, we just
+      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+      available.

+                  FreeType font driver for BDF fonts
+

+
+Introduction
+************
+
+BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
+which is intended to be easily understood by both humans and computers.
+This code implements a BDF driver for the FreeType library, following the
+Adobe Specification V 2.2.  The specification of the BDF font format is
+available from Adobe's web site:
+
+  http://partners.adobe.com/public/developer/en/font/5005.BDF_Spec.pdf
+
+Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
+They do not define vertical metrics, because the X Consortium BDF
+specification has removed them.
+
+
+Encodings
+*********
+
+The variety of encodings that accompanies bdf fonts appears to encompass the
+small set defined in freetype.h.  On the other hand, two properties that
+specify encoding and registry are usually defined in bdf fonts.
+
+I decided to make these two properties directly accessible, leaving to the
+client application the work of interpreting them.  For instance:
+
+
+  #include FT_INTERNAL_BDF_TYPES_H
+
+  FT_Face          face;
+  BDF_Public_Face  bdfface;
+
+
+  FT_New_Face( library, ..., &face );
+
+  bdfface = (BDF_Public_Face)face;
+
+  if ( ( bdfface->charset_registry == "ISO10646" ) &&
+       ( bdfface->charset_encoding == "1" )        )
+    [..]
+
+
+Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+If the two properties are not available, Adobe Standard Encoding should be
+assumed.
+
+
+Anti-Aliased Bitmaps
+********************
+
+The driver supports an extension to the BDF format as used in Mark Leisher's
+xmbdfed bitmap font editor.  Microsoft's SBIT tool expects bitmap fonts in
+that format for adding anti-aliased them to TrueType fonts.  It introduces a
+fourth field to the `SIZE' keyword which gives the bpp value (bits per
+pixel) of the glyph data in the font.  Possible values are 1 (the default),
+2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels).  The
+driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
+per pixel (using 4, 16, and 256 gray levels, respectively).
+
+
+Known problems
+**************
+
+- A font is entirely loaded into memory.  Obviously, this is not the Right
+  Thing(TM).  If you have big fonts I suggest you convert them into PCF
+  format (using the bdftopcf utility): the PCF font drive of FreeType can
+  perform incremental glyph loading.
+
+When I have some time, I will implement on-demand glyph parsing.
+
+- Except for encodings properties, client applications have no visibility of
+  the PCF_Face object.  This means that applications cannot directly access
+  font tables and must trust FreeType.
+
+- Currently, glyph names are ignored.
+
+  I plan to give full visibility of the BDF_Face object in an upcoming
+  revision of the driver, thus implementing also glyph names.
+
+- As I have never seen a BDF font that defines vertical metrics, vertical
+  metrics are (parsed and) discarded.  If you own a BDF font that defines
+  vertical metrics, please let me know (I will implement them in 5-10
+  minutes).

+  /*
+   *
+   *  FTC_GCache is an _abstract_ cache object optimized to store glyph
+   *  data.  It works as follows:
+   *
+   *   - It manages FTC_GNode objects. Each one of them can hold one or more
+   *     glyph `items'.  Item types are not specified in the FTC_GCache but
+   *     in classes that extend it.
+   *
+   *   - Glyph attributes, like face ID, character size, render mode, etc.,
+   *     can be grouped into abstract `glyph families'.  This avoids storing
+   *     the attributes within the FTC_GCache, since it is likely that many
+   *     FTC_GNodes will belong to the same family in typical uses.
+   *
+   *   - Each FTC_GNode is thus an FTC_Node with two additional fields:
+   *
+   *       * gindex: A glyph index, or the first index in a glyph range.
+   *       * family: A pointer to a glyph `family'.
+   *
+   *   - Family types are not fully specific in the FTC_Family type, but
+   *     by classes that extend it.
+   *
+   *  Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
+   *  They share an FTC_Family sub-class called FTC_BasicFamily which is
+   *  used to store the following data: face ID, pixel/point sizes, load
+   *  flags.  For more details see the file `src/cache/ftcbasic.c'.
+   *
+   *  Client applications can extend FTC_GNode with their own FTC_GNode
+   *  and FTC_Family sub-classes to implement more complex caches (e.g.,
+   *  handling automatic synthesis, like obliquing & emboldening, colored
+   *  glyphs, etc.).
+   *
+   *  See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
+   *  `ftcsbits.h', which both extend FTC_GCache with additional
+   *  optimizations.
+   *
+   *  A typical FTC_GCache implementation must provide at least the
+   *  following:
+   *
+   *  - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
+   *        my_node_new            (must call FTC_GNode_Init)
+   *        my_node_free           (must call FTC_GNode_Done)
+   *        my_node_compare        (must call FTC_GNode_Compare)
+   *        my_node_remove_faceid  (must call ftc_gnode_unselect in case
+   *                                of match)
+   *
+   *  - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
+   *        my_family_compare
+   *        my_family_init
+   *        my_family_reset (optional)
+   *        my_family_done
+   *
+   *  - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
+   *    data.
+   *
+   *  - Constant structures for a FTC_GNodeClass.
+   *
+   *  - MyCacheNew() can be implemented easily as a call to the convenience
+   *    function FTC_GCache_New.
+   *
+   *  - MyCacheLookup with a call to FTC_GCache_Lookup.  This function will
+   *    automatically:
+   *
+   *    - Search for the corresponding family in the cache, or create
+   *      a new one if necessary.  Put it in FTC_GQUERY(myquery).family
+   *
+   *    - Call FTC_Cache_Lookup.
+   *
+   *    If it returns NULL, you should create a new node, then call
+   *    ftc_cache_add as usual.

+       *  prevent it from being flushed within the loop.
+       *
+       *  When we exit the loop, we unlock the node, then check the `error'

+       *  completely flushed and that no usable memory was found to load
+       *  the bitmap.
+       *
+       *  We then prefer to return a value of 0 (i.e., NO MATCH).  This
+       *  ensures that the caller will try to allocate a new node.
+       *  This operation consequently _fail_ and the lookup function
+       *  returns the appropriate OOM error code.
+       *
+       *  Note that `buffer == NULL && width == 255' is a hack used to

+   * A poor-man error facility.

+   * This code being written in vanilla C, doesn't have the luxury of a
+   * language-supported exception mechanism such as the one available in
+   * Java.  Instead, we are stuck with using error codes that must be
+   * carefully managed and preserved.  However, it is convenient for us to
+   * model our error mechanism on a Java-like exception mechanism.
+   * When we assign an error code we are thus `throwing' an error.
+   *
+   * The perservation of an error code is done by coding convention.
+   * Upon a function call if the error code is anything other than
+   * `FT_Err_Ok', which is guaranteed to be zero, we
+   * will return without altering that error.  This will allow the
+   * error to propagate and be handled at the appropriate location in
+   * the code.
+   *
+   * This allows a style of code where the error code is initialized
+   * up front and a block of calls are made with the error code only
+   * being checked after the block.  If a new error occurs, the original
+   * error will be preserved and a functional no-op should result in any
+   * subsequent function that has an initial error code not equal to
+   * `FT_Err_Ok'.
+   *
+   * Errors are encoded by calling the `FT_THROW' macro.  For example,
+   *
+   * {
+   *   FT_Error  e;
+   *
+   *
+   *   ...

+gxvalid: TrueType GX validator
+==============================
+
+
+1. What is this
+---------------
+
+  `gxvalid' is a module to  validate TrueType GX tables: a collection of
+  additional tables  in TrueType  font which are  used by  `QuickDraw GX
+  Text',  Apple Advanced  Typography  (AAT).  In  addition, gxvalid  can
+  validates `kern'  tables which have  been extended for AAT.   Like the
+  otvalid  module,   gxvalid  uses  Freetype   2's  validator  framework
+  (ftvalid).
+
+  You can link gxvalid with your program; before running your own layout
+  engine, gxvalid validates a font  file.  As the result, you can remove
+  error-checking code  from the layout  engine.  It is also  possible to
+  use  gxvalid  as a  stand-alone  font  validator;  the `ftvalid'  test
+  program  included  in the  ft2demo  bundle  calls gxvalid  internally.
+  A stand-alone font validator may be useful for font developers.
+
+  This documents documents the following issues.
+
+  - supported TrueType GX tables
+  - fundamental validation limitations
+  - permissive error handling of broken GX tables
+  - `kern' table issue.
+
+
+2. Supported tables
+-------------------
+
+  The following GX tables are currently supported.
+
+    bsln
+    feat
+    just
+    kern(*)
+    lcar
+    mort
+    morx
+    opbd
+    prop
+    trak
+
+  The following GX tables are currently unsupported.
+
+    cvar
+    fdsc
+    fmtx
+    fvar
+    gvar
+    Zapf
+
+  The following GX tables won't be supported.
+
+    acnt(**)
+    hsty(***)
+
+  The following undocumented tables in TrueType fonts designed for Apple
+  platform aren't handled either.
+
+    addg
+    CVTM
+    TPNM
+    umif
+
+
+  *)   The `kern'  validator handles both  the classic and the  new kern
+       formats;  the former  is supported  on both  Microsoft  and Apple
+       platforms, while the latter is supported on Apple platforms.
+
+  **)  `acnt' tables are not supported by currently available Apple font
+       tools.
+
+  ***) There  is  one more  Apple  extension,  `hsty',  but  it  is  for
+       Newton-OS, not GX  (Newton-OS is a platform by  Apple, but it can
+       use  sfnt- housed bitmap  fonts only).   Therefore, it  should be
+       excluded  from  `Apple  platform'  in the  context  of  TrueType.
+       gxvalid ignores it as Apple font tools do so.
+
+
+  We have  checked 183  fonts bundled with  MacOS 9.1, MacOS  9.2, MacOS
+  10.0, MacOS X 10.1, MSIE  for MacOS, and AppleWorks 6.0.  In addition,
+  we have  checked 67 Dynalab fonts  (designed for MacOS)  and 189 Ricoh
+  fonts (designed for Windows and  MacOS dual platforms).  The number of
+  fonts including TrueType GX tables are as follows.
+
+    bsln:  76
+    feat: 191
+    just:  84
+    kern:  59
+    lcar:   4
+    mort: 326
+    morx:  19
+    opbd:   4
+    prop: 114
+    trak:  16
+
+  Dynalab  and Ricoh fonts  don't have  GX tables  except of  `feat' and
+  `mort'.
+
+
+3. Fundamental validation limitations
+-------------------------------------
+
+  TrueType  GX  provides  layout   information  to  libraries  for  font
+  rasterizers  and text layout.   gxvalid can  check whether  the layout
+  data in  a font is conformant  to the TrueType GX  format specified by
+  Apple.  But gxvalid cannot check  a how QuickDraw GX/AAT renderer uses
+  the stored information.
+
+  3-1. Validation of State Machine activity
+  -----------------------------------------
+
+    QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
+    features,  and TrueType GX  stores the  state transition  diagram of
+    this `State  Machine' in a  `StateTable' data structure.   While the
+    State  Machine receives  a series  of glyph  IDs, the  State Machine
+    starts with `start  of text' state, walks around  various states and
+    generates various  layout information  to the  renderer, and finally
+    reaches the `end of text' state.
+
+    gxvalid can check essential errors like:
+
+      - possibility of state transitions to undefined states
+      - existence of glyph  IDs that the State Machine  doesn't know how
+        to handle
+      - the  State Machine  cannot compute  the layout  information from
+        given diagram
+
+    These errors  can be  checked within finite  steps, and  without the
+    State Machine itself, because these are `expression' errors of state
+    transition diagram.
+
+    There  is no  limitation  about  how long  the  State Machine  walks
+    around,  so validation  of  the algorithm  in  the state  transition
+    diagram requires infinite  steps, even if we had  a State Machine in
+    gxvalid.   Therefore, the  following errors  and problems  cannot be
+    checked.
+
+      - existence of states which the State Machine never transits to
+      - the  possibility that the  State Machine  never reaches  `end of
+        text'
+      - the possibility of stack underflow/overflow in the State Machine
+        (in  ligature  and  contextual  glyph substitutions,  the  State
+        Machine can store 16 glyphs onto its stack)
+
+    In addition, gxvalid doesn't check `temporary glyph IDs' used in the
+    chained State Machines  (in `mort' and `morx' tables).   If a layout
+    feature  is  implemented by  a  single  State  Machine, a  glyph  ID
+    converted by the State Machine is passed to the glyph renderer, thus
+    it  should not  point to  an undefined  glyph ID.   But if  a layout
+    feature is implemented by  chained State Machines, a component State
+    Machine  (if it  is  not the  final  one) is  permitted to  generate
+    undefined glyph IDs for temporary use, because it is handled by next
+    component State Machine and not  by the glyph renderer.  To validate
+    such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
+    which  can occur in  the output  of the  previous State  Machine and
+    search  them in  the  `ClassTable' structure  of  the current  State
+    Machine.  It is too complex to  list all possible glyph IDs from the
+    StateTable, especially from a ligature substitution table.
+
+  3-2. Validation of relationship between multiple layout features
+  ----------------------------------------------------------------
+
+    gxvalid does  not validate the relationship  between multiple layout
+    features at all.
+
+    If  multiple layout  features  are defined  in  TrueType GX  tables,
+    possible  interactions,  overrides,  and  conflicts  between  layout
+    features are implicitly  given in the font too.   For example, there
+    are several predefined spacing control features:
+
+      - Text Spacing          (Proportional/Monospace/Half-width/Normal)
+      - Number Spacing        (Monospaced-numbers/Proportional-numbers)
+      - Kana Spacing          (Full-width/Proportional)
+      - Ideographic Spacing   (Full-width/Proportional)
+      - CJK Roman Spacing     (Half-width/Proportional/Default-roman
+                               /Full-width-roman/Proportional)
+
+    If all  layout features are  independently managed, we  can activate
+    inconsistent  typographic rules  like  `Text Spacing=Monospace'  and
+    `Ideographic Spacing=Proportional' at the same time.
+
+    The combinations  of layout features  is managed by a  32bit integer
+    (one bit each for selector  setting), so we can define relationships
+    between  up  to 32  features,  theoretically.   But  if one  feature
+    setting  affects  another   feature  setting,  we  need  typographic
+    priority  rules to  validate the  relationship.   Unfortunately, the
+    TrueType GX format specification does not give such information even
+    for predefined features.
+
+
+4. Permissive error handling of broken GX tables
+------------------------------------------------
+
+  When  Apple's font  rendering system  finds an  inconsistency,  like a
+  specification  violation or  an  unspecified value  in  a TrueType  GX
+  table, it does not always  return error.  In most cases, the rendering
+  engine silently  ignores such wrong  values or even whole  tables.  In
+  fact, MacOS is shipped with  fonts including broken GX/AAT tables, but
+  no harmful  effects due to  `officially broken' fonts are  observed by
+  end-users.
+
+  gxvalid  is designed  to continue  the validation  process as  long as
+  possible.  When gxvalid find wrong  values, gxvalid warns it at least,
+  and takes  a fallback procedure  if possible.  The  fallback procedure
+  depends on the debug level.
+
+  We used the following three tools to investigate Apple's error handling.
+
+    - FontValidator  (for MacOS 8.5 - 9.2)  resource fork font
+    - ftxvalidator   (for MacOS X 10.1 -)   dfont or naked-sfnt
+    - ftxdumperfuser (for MacOS X 10.1 -)   dfont or naked-sfnt
+
+  However, all tests were done on a PowerPC based Macintosh; at present,
+  we have not checked those tools on a m68k-based Macintosh.
+
+  In total, we checked 183 fonts  bundled to MacOS 9.1, MacOS 9.2, MacOS
+  10.0, MacOS X  10.1, MSIE for MacOS, and  AppleWorks 6.0.  These fonts
+  are distributed  officially, but many broken GX/AAT  tables were found
+  by Apple's font tools.  In the following, we list typical violation of
+  the GX specification, in fonts officially distributed with those Apple
+  systems.
+
+  4-1. broken BinSrchHeader (19/183)
+  ----------------------------------
+
+    `BinSrchHeader' is  a header of a  data array for  m68k platforms to
+    access memory efficiently.  Although  there are only two independent
+    parameters  for real  (`unitSize' and  `nUnits'),  BinSrchHeader has
+    three additional parameters which  can be calculated from `unitSize'
+    and  `nUnits',  for  fast  setup.   Apple  font  tools  ignore  them
+    silently, so gxvalid warns if it finds and inconsistency, and always
+    continues  validation.    The  additional  parameters   are  ignored
+    regardless of the consistency.
+
+      19  fonts include  such  inconsistencies; all  breaks  are in  the
+      BinSrchHeader structure of the `kern' table.
+
+  4-2. too-short LookupTable (5/183)
+  ----------------------------------
+
+    LookupTable format 0  is a simple array to get a  value from a given
+    GID (glyph  ID); the index of  this array is a  GID too.  Therefore,
+    the length  of the array is expected  to be same as  the maximum GID
+    value defined  in the `maxp' table,  but there are  some fonts whose
+    LookupTable format 0 is too  short to cover all GIDs.  FontValidator
+    ignores  this error silently,  ftxvalidator and  ftxdumperfuser both
+    warn and continue.  Similar problems are found in format 3 subtables
+    of `kern'.  gxvalid  warns always and abort if  the validation level
+    is set to FT_VALIDATE_PARANOID.
+
+      5 fonts include too-short kern format 0 subtables.
+      1 font includes too-short kern format 3 subtable.
+
+  4-3. broken LookupTable format 2 (1/183)
+  ----------------------------------------
+
+    LookupTable  format  2,  subformat  4  covers the  GID  space  by  a
+    collection  of  segments which  are  specified  by `firstGlyph'  and
+    `lastGlyph'.   Some  fonts  store  `firstGlyph' and  `lastGlyph'  in
+    reverse order,  so the segment specification is  broken.  Apple font
+    tools ignore this error silently;  a broken segment is ignored as if
+    it  did not  exist.   gxvalid  warns and  normalize  the segment  at
+    FT_VALIDATE_DEFAULT, or ignore  the segment at FT_VALIDATE_TIGHT, or
+    abort at FT_VALIDATE_PARANOID.
+
+      1 font includes broken LookupTable format 2, in the `just' table.
+
+    *) It seems  that all fonts manufactured by  ITC for AppleWorks have
+       this error.
+
+  4-4. bad bracketing in glyph property (14/183)
+  ----------------------------------------------
+
+    GX/AAT defines a  `bracketing' property of the glyphs  in the `prop'
+    table,  to control layout  features of  strings enclosed  inside and
+    outside  of   brackets.   Some  fonts   give  inappropriate  bracket
+    properties  to glyphs.   Apple  font tools  warn  about this  error;
+    gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
+
+      14 fonts include wrong bracket properties.
+
+
+  4-5. invalid feature number (117/183)
+  -------------------------------------
+
+    The GX/AAT extension can  include 255 different layout features, but
+    popular      layout      features      are      predefined      (see
+    http://developer.apple.com/fonts/Registry/index.html).   Some  fonts
+    include feature  numbers which are incompatible  with the predefined
+    feature registry.
+
+    In our survey, there are 140 fonts including `feat' table.
+
+    a) 67 fonts use a feature number which should not be used.
+    b) 117 fonts set the wrong feature range (nSetting).  This is mostly
+       found in the `mort' and `morx' tables.
+
+    Apple  font tools give  no warning,  although they  cannot recognize
+    what  the feature  is.   At FT_VALIDATE_DEFAULT,  gxvalid warns  but
+    continues in both cases (a, b).  At FT_VALIDATE_TIGHT, gxvalid warns
+    and aborts for (a), but continues for (b).  At FT_VALIDATE_PARANOID,
+    gxvalid warns and aborts in both cases (a, b).
+
+  4-6. invalid prop version (10/183)
+  ----------------------------------
+
+    As most TrueType GX tables, the `prop' table must start with a 32bit
+    version identifier: 0x00010000,  0x00020000 or 0x00030000.  But some
+    fonts  store nonsense binary  data instead.   When Apple  font tools
+    find them, they abort the processing immediately, and the data which
+    follows is unhandled.  gxvalid does the same.
+
+      10 fonts include broken `prop' version.
+
+    All  of these  fonts are  classic  TrueType fonts  for the  Japanese
+    script, manufactured by Apple.
+
+  4-7. unknown resource name (2/183)
+  ------------------------------------
+
+    NOTE: THIS IS NOT A TRUETYPE GX ERROR.
+
+    If  a TrueType  font is  stored  in the  resource fork  or in  dfont
+    format, the data must be tagged as `sfnt' in the resource fork index
+    to invoke TrueType font handler for the data.  But the TrueType font
+    data  in   `Keyboard.dfont'  is  tagged   as  `kbd',  and   that  in
+    `LastResort.dfont' is tagged as  `lst'.  Apple font tools can detect
+    that the data is in  TrueType format and successfully validate them.
+    Maybe  this is possible  because they  are known  to be  dfont.  The
+    current  implementation  of the  resource  fork  driver of  FreeType
+    cannot do that, thus gxvalid cannot validate them.
+
+      2 fonts use an unknown tag for the TrueType font resource.
+
+5. `kern' table issues
+----------------------
+
+  In common terminology of TrueType, `kern' is classified as a basic and
+  platform-independent table.  But there are Apple extensions of `kern',
+  and  there is  an  extension which  requires  a GX  state machine  for
+  contextual kerning.   Therefore, gxvalid includes  a special validator
+  for  `kern' tables.   Unfortunately, there  is no  exact  algorithm to
+  check Apple's extension, so  gxvalid includes a heuristic algorithm to
+  find  the proper validation  routines for  all possible  data formats,
+  including    the   data    format   for    Microsoft.     By   calling
+  classic_kern_validate() instead of gxv_validate(), you can specify the
+  `kern' format  explicitly.  However, current  FreeType2 uses Microsoft
+  `kern' format  only, others  are ignored (and  should be handled  in a
+  library one level higher than FreeType).
+
+  5-1. History
+  ------------
+
+    The original  16bit version of `kern'  was designed by  Apple in the
+    pre-GX  era, and  it was  also approved  by  Microsoft.  Afterwards,
+    Apple designed a  new 32bit version of the  `kern' table.  According
+    to  the documentation, the  difference between  the 16bit  and 32bit
+    version is only the size of  variables in the `kern' header.  In the
+    following,  we call  the original  16bit version  as  `classic', and
+    32bit version as `new'.
+
+  5-2. Versions and dialects which should be differentiated
+  ---------------------------------------------------------
+
+    The `kern' table  consists of a table header  and several subtables.
+    The version number  which identifies a `classic' or  a `new' version
+    is  explicitly   written  in  the   table  header,  but   there  are
+    undocumented  differences between  Microsoft's and  Apple's formats.
+    It is  called a `dialect' in  the following.  There  are three cases
+    which  should  be  handled:   the  new  Apple-dialect,  the  classic
+    Apple-dialect,  and the classic  Microsoft-dialect.  An  analysis of
+    the formats and the auto detection algorithm of gxvalid is described
+    in the following.
+
+    5-2-1. Version detection: classic and new kern
+    ----------------------------------------------
+
+      According  to Apple  TrueType  specification, there  are only  two
+      differences between the classic and the new:
+
+        - The `kern' table header starts with the version number.
+          The classic version starts with 0x0000 (16bit),
+          the new version starts with 0x00010000 (32bit).
+
+        - In the  `kern' table header,  the number of  subtables follows
+          the version number.
+          In the classic version, it is stored as a 16bit value.
+          In the new version, it is stored as a 32bit value.
+
+      From Apple font tool's output (DumpKERN is also tested in addition
+      to  the  three  Apple  font  tools in  above),  there  is  another
+      undocumented difference.  In the  new version, the subtable header
+      includes a 16bit variable  named `tupleIndex' which does not exist
+      in the classic version.
+
+      The new version  can store all subtable formats (0,  1, 2, and 3),
+      but the Apple TrueType specification does not mention the subtable
+      formats available in the classic version.
+
+    5-2-2. Available subtable formats in classic version
+    ----------------------------------------------------
+
+      Although the  Apple TrueType  specification recommends to  use the
+      classic version in  the case if the font is  designed for both the
+      Apple and Microsoft platforms,  it does not document the available
+      subtable formats in the classic version.
+
+      According  to the Microsoft  TrueType specification,  the subtable
+      format  assured for  Windows  and OS/2  support  is only  subtable
+      format  0.  The  Microsoft TrueType  specification  also describes
+      subtable format  2, but does  not mention which  platforms support
+      it.  Aubtable formats 1, 3,  and higher are documented as reserved
+      for future use.  Therefore, the classic version can store subtable
+      formats 0 and 2, at least.  `ttfdump.exe', a font tool provided by
+      Microsoft,  ignores the  subtable format  written in  the subtable
+      header, and parses the table as if all subtables are in format 0.
+
+      `kern'  subtable format  1  uses  a StateTable,  so  it cannot  be
+      utilized without a GX  State Machine.  Therefore, it is reasonable
+      to assume  that format 1 (and  3) were introduced  after Apple had
+      introduced GX and moved to the new 32bit version.
+
+    5-2-3. Apple and Microsoft dialects
+    -----------------------------------
+
+      The  `kern' subtable  has  a 16bit  `coverage'  field to  describe
+      kerning attributes, but bit interpretations by Apple and Microsoft
+      are different:  For example, Apple  uses bits 0-7 to  identify the
+      subtable, while Microsoft uses bits 8-15.
+
+      In  addition, due  to the  output of  DumpKERN  and FontValidator,
+      Apple's bit interpretations of coverage in classic and new version
+      are  incompatible also.   In  summary, there  are three  dialects:
+      classic Apple  dialect, classic  Microsoft dialect, and  new Apple
+      dialect.  The classic Microsoft  dialect and the new Apple dialect
+      are documented  by each vendors' TrueType  font specification, but
+      the documentation for classic Apple dialect is not available.
+
+      For example,  in the  new Apple dialect,  bit 15 is  documented as
+      `set to  1 if  the kerning  is vertical'.  On  the other  hand, in
+      classic Microsoft dialect, bit 1 is documented as `set to 1 if the
+      kerning  is  horizontal'.   From   the  outputs  of  DumpKERN  and
+      FontValidator, classic  Apple dialect recognizes  15 as `set  to 1
+      when  the kerning  is horizontal'.   From the  results  of similar
+      experiments, classic Apple dialect  seems to be the Endian reverse
+      of the classic Microsoft dialect.
+
+      As a  conclusion it must be  noted that no font  tool can identify
+      classic Apple dialect or classic Microsoft dialect automatically.
+
+    5-2-4. gxvalid auto dialect detection algorithm
+    -----------------------------------------------
+
+      The first 16  bits of the `kern' table are  enough to identify the
+      version:
+
+        - if  the first  16  bits are  0x0000,  the `kern'  table is  in
+          classic Apple dialect or classic Microsoft dialect
+        - if the first 16 bits are  0x0001, and next 16 bits are 0x0000,
+          the kern table is in new Apple dialect.
+
+      If the `kern'  table is a classic one,  the 16bit `coverage' field
+      is checked next.   Firstly, the coverage bits are  decoded for the
+      classic Apple dialect using the following bit masks (this is based
+      on DumpKERN output):
+
+        0x8000: 1=horizontal, 0=vertical
+        0x4000: not used
+        0x2000: 1=cross-stream, 0=normal
+        0x1FF0: reserved
+        0x000F: subtable format
+
+      If  any  of  reserved  bits  are  set  or  the  subtable  bits  is
+      interpreted as format 1 or 3, we take it as `impossible in classic
+      Apple dialect' and retry, using the classic Microsoft dialect.
+
+        The most popular coverage in new Apple-dialect:         0x8000,
+        The most popular coverage in classic Apple-dialect:     0x0000,
+        The most popular coverage in classic Microsoft dialect: 0x0001.
+
+  5-3. Tested fonts
+  -----------------
+
+    We checked  59 fonts  bundled with MacOS  and 38 fonts  bundled with
+    Windows, where all font include a `kern' table.
+
+      - fonts bundled with MacOS
+        * new Apple dialect
+          format 0: 18
+          format 2:  1
+          format 3:  1
+        * classic Apple dialect
+          format 0: 14
+        * classic Microsoft dialect
+          format 0: 15
+
+      - fonts bundled with Windows
+        * classic Microsoft dialect
+          format 0: 38
+
+    It looks strange that classic Microsoft-dialect fonts are bundled to
+    MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.
+
+
+  ACKNOWLEDGEMENT
+  ---------------
+
+  Some parts of gxvalid are  derived from both the `gxlayout' module and
+  the `otvalid'  module.  Development of  gxlayout was supported  by the
+  Information-technology Promotion Agency(IPA), Japan.
+
+  The detailed analysis of undefined  glyph ID utilization in `mort' and
+  `morx' tables is provided by George Williams.

+   Notes beyond the 1.93a appnote.txt:
+
+   1. Distance pointers never point before the beginning of the output
+      stream.
+   2. Distance pointers can point back across blocks, up to 32k away.
+   3. There is an implied maximum of 7 bits for the bit length table and
+      15 bits for the actual data.
+   4. If only one code exists, then it is encoded using one bit.  (Zero
+      would be more efficient, but perhaps a little confusing.)  If two
+      codes exist, they are coded using one bit each (0 and 1).
+   5. There is no way of sending zero distance codes--a dummy must be
+      sent if there are none.  (History: a pre 2.0 version of PKZIP would
+      store blocks with no distance codes, but this was discovered to be
+      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
+      zero distance codes, which is sent as one code of zero bits in
+      length.
+   6. There are up to 286 literal/length codes.  Code 256 represents the
+      end-of-block.  Note however that the static length tree defines
+      288 codes just to fill out the Huffman codes.  Codes 286 and 287
+      cannot be used though, since there is no length base or extra bits
+      defined for them.  Similarily, there are up to 30 distance codes.
+      However, static trees define 32 codes (all 5 bits) to fill out the
+      Huffman codes, but the last two had better not show up in the data.
+   7. Unzip can check dynamic Huffman blocks for complete code sets.
+      The exception is that a single code would not be complete (see #4).
+   8. The five bits following the block type is really the number of
+      literal codes sent minus 257.
+   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+      (1+6+6).  Therefore, to output three times the length, you output
+      three codes (1+1+1), whereas to output four times the same length,
+      you only need two codes (1+3).  Hmm.
+  10. In the tree reconstruction algorithm, Code = Code + Increment
+      only if BitLength(i) is not zero.  (Pretty obvious.)
+  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
+  12. Note: length code 284 can represent 227-258, but length code 285
+      really is 258.  The last length deserves its own, short code
+      since it gets used a lot in very redundant files.  The length
+      258 is special since 258 - 3 (the min match length) is 255.
+  13. The literal/length and distance code bit lengths are read as a
+      single stream of lengths.  It is possible (and advantageous) for
+      a repeat code (16, 17, or 18) to go across the boundary between
+      the two sets of lengths.

+   Huffman code decoding is performed using a multi-level table lookup.
+   The fastest way to decode is to simply build a lookup table whose
+   size is determined by the longest code.  However, the time it takes
+   to build this table can also be a factor if the data being decoded
+   is not very long.  The most common codes are necessarily the
+   shortest codes, so those codes dominate the decoding time, and hence
+   the speed.  The idea is you can have a shorter table that decodes the
+   shorter, more probable codes, and then point to subsidiary tables for
+   the longer codes.  The time it costs to decode the longer codes is
+   then traded against the time it takes to make longer tables.
+
+   This results of this trade are in the variables lbits and dbits
+   below.  lbits is the number of bits the first level table for literal/
+   length codes can decode in one step, and dbits is the same thing for
+   the distance codes.  Subsequent tables are also less than or equal to
+   those sizes.  These values may be adjusted either when all of the
+   codes are shorter than that, in which case the longest code length in
+   bits is used, or when the shortest code is *longer* than the requested
+   table size, in which case the length of the shortest code in bits is
+   used.
+
+   There are two different values for the two tables, since they code a
+   different number of possibilities each.  The literal/length table
+   codes 286 possible values, or in a flat code, a little over eight
+   bits.  The distance table codes 30 possible values, or a little less
+   than five bits, flat.  The optimum values for speed end up being
+   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+   The optimum values may differ though from machine to machine, and
+   possibly even between compilers.  Your mileage may vary.

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+   The application must update next_in and avail_in when avail_in has

+   has dropped to zero. The application must initialize zalloc, zfree and
+   opaque before calling the init function. All other fields are set by the
+   compression library and must not be updated by the application.
+
+   The opaque value provided by the application will be passed as the first
+   parameter for calls of zalloc and zfree. This can be useful for custom
+   memory management. The compression library attaches no meaning to the
+   opaque value.
+
+   zalloc must return Z_NULL if there is not enough memory for the object.
+   If zlib is used in a multi-threaded application, zalloc and zfree must be
+   thread safe.
+
+   On 16-bit systems, the functions zalloc and zfree must be able to allocate
+   exactly 65536 bytes, but will not be required to allocate more than this
+   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
+   pointers returned by zalloc for objects of exactly 65536 bytes *must*
+   have their offset normalized to zero. The default allocation function
+   provided by this library ensures this (see zutil.c). To reduce memory
+   requirements and avoid any allocation of 64K objects, at the expense of
+   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
+
+   The fields total_in and total_out can be used for statistics or
+   progress reports. After compression, total_in holds the total size of
+   the uncompressed data and may be saved for use in the decompressor
+   (particularly if the decompressor wants to decompress everything in
+   a single step).

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

+  might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
+  output as possible to the output buffer. The flushing behavior of inflate is
+  not specified for values of the flush parameter other than Z_SYNC_FLUSH
+  and Z_FINISH, but the current implementation actually flushes as much output
+  as possible anyway.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must

+  is never required, but can be used to inform inflate that a faster routine
+  may be used for the single inflate() call.

+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.

+   used strings preferably put towards the end of the dictionary. Using a

+   *  small technical note
+   *  --------------------
+   *
+   *  We use a few tricks in this implementation that are explained here to
+   *  ease debugging and maintenance.
+   *
+   *  - First of all, the `prefix' and `suffix' arrays contain the suffix
+   *    and prefix for codes over 256; this means that
+   *
+   *      prefix_of(code) == state->prefix[code-256]
+   *      suffix_of(code) == state->suffix[code-256]
+   *
+   *    Each prefix is a 16-bit code, and each suffix an 8-bit byte.
+   *
+   *    Both arrays are stored in a single memory block, pointed to by
+   *    `state->prefix'.  This means that the following equality is always
+   *    true:
+   *
+   *      state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
+   *
+   *    Of course, state->prefix_size is the number of prefix/suffix slots
+   *    in the arrays, corresponding to codes 256..255+prefix_size.
+   *
+   *  - `free_ent' is the index of the next free entry in the `prefix'
+   *    and `suffix' arrays.  This means that the corresponding `next free
+   *    code' is really `256+free_ent'.
+   *
+   *    Moreover, `max_free' is the maximum value that `free_ent' can reach.
+   *
+   *    `max_free' corresponds to `(1 << max_bits) - 256'.  Note that this
+   *    value is always <= 0xFF00, which means that both `free_ent' and
+   *    `max_free' can be stored in an FT_UInt variable, even on 16-bit
+   *    machines.
+   *
+   *    If `free_ent == max_free', you cannot add new codes to the
+   *    prefix/suffix table.
+   *
+   *  - `num_bits' is the current number of code bits, starting at 9 and
+   *    growing each time `free_ent' reaches the value of `free_bits'.  The
+   *    latter is computed as follows
+   *
+   *      if num_bits < max_bits:
+   *         free_bits = (1 << num_bits)-256
+   *      else:
+   *         free_bits = max_free + 1
+   *
+   *    Since the value of `max_free + 1' can never be reached by
+   *    `free_ent', `num_bits' cannot grow larger than `max_bits'.

+Introduction
+************
+
+PCF (Portable Compiled Format) is a binary bitmap font format, largely used
+in X world. This code implements a PCF driver for the FreeType library.
+Glyph images are loaded into memory only on demand, thus leading to a small
+memory footprint.
+
+Information on the PCF font format can only be worked out from
+`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
+(www.xfree86.org) source tree (xc/lib/font/bitmap/).
+
+Many good bitmap fonts in bdf format come with XFree86: they can be
+compiled into the pcf format using the `bdftopcf' utility.
+
+
+Supported hardware
+******************
+
+The driver has been tested on linux/x86 and sunos5.5/sparc.  In both
+cases the compiler was gcc.  When back in Paris, I will test it also
+on linux/alpha.
+
+
+Encodings
+*********
+
+Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
+
+The driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+
+Known problems
+**************
+
+- dealing explicitly with encodings breaks the uniformity of freetype2
+  api.
+
+- except for encodings properties, client applications have no
+  visibility of the PCF_Face object.  This means that applications
+  cannot directly access font tables and are obliged to trust
+  FreeType.
+
+- currently, glyph names and ink_metrics are ignored.
+
+I plan to give full visibility of the PCF_Face object in the next
+release of the driver, thus implementing also glyph names and
+ink_metrics.
+
+- height is defined as (ascent - descent).  Is this correct?
+
+- if unable to read size information from the font, PCF_Init_Face
+  sets available_size->width and available_size->height to 12.
+
+- too many english grammar errors in the readme file :-(

+the same time the specification and the sample implementation of the
+PCF format.  Undoubtedly, this driver is inspired from his work.

+ftfuzzer
+========
+
+
+ftfuzzer.cc
+-----------
+
+This file contains a target function  for FreeType fuzzing.  It can be
+used    with   libFuzzer    (http://llvm.org/docs/LibFuzzer.html)   or
+potentially any other similar fuzzer.
+
+Usage:
+
+  1. Build  `libfreetype.a' and  `ftfuzzer.cc' using  the most  recent
+     clang compiler with these flags:
+
+       # for fuzzer coverage feedback
+       -fsanitize-coverage=edge,8bit-counters
+       # for bug checking
+       -fsanitize=address,signed-integer-overflow,shift
+
+     You  also need  the header  files from  the `libarchive'  library
+     (http://www.libarchive.org/)  for handling  tar  files (see  file
+     `ftmutator.cc' below for more).
+
+  2. Link with `libFuzzer' (it contains `main') and `libarchive'.
+
+  3. Run the fuzzer on some test corpus.
+
+The exact flags and commands may vary.
+
+
+There is a continuous fuzzing bot that runs ftfuzzer.
+
+  https://github.com/google/libfuzzer-bot/tree/master/freetype
+
+Check the bot configuration for the most current settings.
+
+
+ftmutator.cc
+------------
+
+FreeType has the  ability to `attach' auxiliary files to  a font file,
+providing additional information.  The main usage is to load AFM files
+for PostScript Type 1 fonts.
+
+However, libFuzzer currently only supports  mutation of a single input
+file.   For  this  reason,  `ftmutator.cc' contains  a  custom  fuzzer
+mutator that uses an uncompressed tar  file archive as the input.  The
+first file in  such a tarball gets  opened by FreeType as  a font, all
+other files are treated as input for `FT_Attach_Stream'.
+
+Compilation is similar to `ftfuzzer.c'.
+
+
+runinput.cc
+-----------
+
+To run the target function on a set of input files, this file contains
+a   convenience  `main'   function.   Link   it  with   `ftfuzzer.cc',
+`libfreetype.a', and `libarchive' and run like
+
+  ./a.out my_tests_inputs/*

+ftrandom
+========
+
+This program expects a set of directories containing good fonts, and a set
+of extensions of fonts to be tested.  It will randomly pick a font, copy it,
+introduce an error and then test it.
+
+The FreeType tests are quite basic; for each erroneous font ftrandom
+
+  . forks off a new tester,
+  . initializes the library,
+  . opens each font in the file,
+  . loads each glyph,
+  . optionally reviews the contours of the glyph,
+  . optionally rasterizes the glyph, and
+  . closes the face.
+
+If a tester takes longer than 20 seconds, ftrandom saves the erroneous font
+and continues.  If the tester exits normally or with an error, then the
+superstructure removes the test font and continues.
+
+
+Command line options
+--------------------
+
+  --all                    Test every font in the directory(ies) no matter
+                           what its extension.
+  --check-outlines         Call `FT_Outline_Decompose' on each glyph.
+  --dir <dir>              Append <dir> to the list of directories to search
+                           for good fonts.  No recursive search.
+  --error-count <cnt>      Introduce <cnt> single-byte errors into the
+                           erroneous fonts (default: 1).
+  --error-fraction <frac>  Multiply the file size of the font by <frac> and
+                           introduce that many errors into the erroneous
+                           font file.  <frac> should be in the range [0;1]
+                           (default: 0.0).
+  --ext <ext>              Add <ext> to the set of font types tested.
+  --help                   Print out this list of options.
+  --nohints                Specify FT_LOAD_NO_HINTING when loading glyphs.
+  --rasterize              Call `FT_Render_Glyph' as well as loading it.
+  --result <dir>           This is the directory in which test files are
+                           placed.
+  --test <file>            Run a single test on a pre-generated testcase.
+                           This is done in the current process so it can be
+                           debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+  .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+  /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+  memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+  example, then link it with ftrandom.

+# We now store the Adobe Glyph List in compressed form.  The list is put
+# into a data structure called `trie' (because it has a tree-like
+# appearance).  Consider, for example, that you want to store the
+# following name mapping:
+#
+#   A        => 1
+#   Aacute   => 6
+#   Abalon   => 2
+#   Abstract => 4
+#
+# It is possible to store the entries as follows.
+#
+#   A => 1
+#   |
+#   +-acute => 6
+#   |
+#   +-b
+#     |
+#     +-alon => 2
+#     |
+#     +-stract => 4
+#
+# We see that each node in the trie has:
+#
+# - one or more `letters'
+# - an optional value
+# - zero or more child nodes
+#
+# The first step is to call
+#
+#   root = StringNode( "", 0 )
+#   for word in map.values():
+#     root.add( word, map[word] )
+#
+# which creates a large trie where each node has only one children.
+#
+# Executing
+#
+#   root = root.optimize()
+#
+# optimizes the trie by merging the letters of successive nodes whenever
+# possible.
+#
+# Each node of the trie is stored as follows.
+#
+# - First the node's letter, according to the following scheme.  We
+#   use the fact that in the AGL no name contains character codes > 127.
+#
+#     name         bitsize     description
+#     ----------------------------------------------------------------
+#     notlast            1     Set to 1 if this is not the last letter
+#                              in the word.
+#     ascii              7     The letter's ASCII value.
+#
+# - The letter is followed by a children count and the value of the
+#   current key (if any).  Again we can do some optimization because all
+#   AGL entries are from the BMP; this means that 16 bits are sufficient
+#   to store its Unicode values.  Additionally, no node has more than
+#   127 children.
+#
+#     name         bitsize     description
+#     -----------------------------------------
+#     hasvalue           1     Set to 1 if a 16-bit Unicode value follows.
+#     num_children       7     Number of children.  Can be 0 only if
+#                              `hasvalue' is set to 1.
+#     value             16     Optional Unicode value.
+#
+# - A node is finished by a list of 16bit absolute offsets to the
+#   children, which must be sorted in increasing order of their first
+#   letter.
+#
+# For simplicity, all 16bit quantities are stored in big-endian order.
+#
+# The root node has first letter = 0, and no value.

+   * Calculate the phantom points
+   *
+   * Defining the right side bearing (rsb) as

+   *   rsb = aw - (lsb + xmax - xmin)
+   *
+   * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
+   * and `xmax' the glyph's minimum and maximum x value), the OpenType
+   * specification defines the initial position of horizontal phantom points
+   * as
+   *
+   *   pp1 = (round(xmin - lsb), 0)      ,
+   *   pp2 = (round(pp1 + aw), 0)        .
+   *
+   * Note that the rounding to the grid (in the device space) is not
+   * documented currently in the specification.
+   *
+   * However, the specification lacks the precise definition of vertical
+   * phantom points.  Greg Hitchcock provided the following explanation.
+   *
+   * - a `vmtx' table is present
+   *
+   *   For any glyph, the minimum and maximum y values (`ymin' and `ymax')
+   *   are given in the `glyf' table, the top side bearing (tsb) and advance
+   *   height (ah) are given in the `vmtx' table.  The bottom side bearing
+   *   (bsb) is then calculated as
+   *
+   *     bsb = ah - (tsb + ymax - ymin)       ,
+   *
+   *   and the initial position of vertical phantom points is
+   *
+   *     pp3 = (x, round(ymax + tsb))       ,
+   *     pp4 = (x, round(pp3 - ah))         .
+   *
+   *   See below for value `x'.
+   *
+   * - no `vmtx' table in the font
+   *
+   *   If there is an `OS/2' table, we set
+   *
+   *     DefaultAscender = sTypoAscender       ,
+   *     DefaultDescender = sTypoDescender     ,
+   *
+   *   otherwise we use data from the `hhea' table:
+   *
+   *     DefaultAscender = Ascender         ,
+   *     DefaultDescender = Descender       .
+   *
+   *   With these two variables we can now set
+   *
+   *     ah = DefaultAscender - sDefaultDescender    ,
+   *     tsb = DefaultAscender - yMax                ,
+   *
+   *   and proceed as if a `vmtx' table was present.
+   *
+   * Usually we have
+   *
+   *   x = aw / 2      ,                                                (1)
+   *
+   * but there is one compatibility case where it can be set to
+   *
+   *   x = -DefaultDescender -
+   *         ((DefaultAscender - DefaultDescender - aw) / 2)     .      (2)
+   *
+   * and another one with
+   *
+   *   x = 0     .                                                      (3)
+   *
+   * In Windows, the history of those values is quite complicated,

+     * bytecode contained in these fonts to make them look ClearType-y
+     * somehow.  Most (web)fonts that were released since then have come to
+     * rely on these hacks to render correctly, even some of Microsoft's
+     * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
+     *
+     * The minimal subpixel hinting code (interpreter version 40) employs a
+     * small list of font-agnostic hacks to bludgeon non-native-ClearType
+     * fonts (except tricky ones[1]) into submission.  It will not try to
+     * toggle hacks for specific fonts for performance and complexity
+     * reasons.  The focus is on modern (web)fonts rather than legacy fonts
+     * that were made for black-and-white rendering.
+     *
+     * Major hacks
+     *
+     * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+     *   `Direct_Move_X').  This has the smallest code footprint and single
+     *   biggest effect.  The ClearType way to increase resolution is
+     *   supersampling the x axis, the FreeType way is ignoring instructions
+     *   on the x axis, which gives the same result in the majority of
+     *   cases.
+     *
+     * - Points are not moved post-IUP (neither on the x nor on the y axis),
+     *   except the x component of diagonal moves post-IUP (cf.
+     *   `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point').  Post-IUP
+     *   changes are commonly used to `fix' pixel patterns which has little
+     *   use outside monochrome rendering.
+     *
+     * - SHPIX and DELTAP don't execute unless moving a composite on the
+     *   y axis or moving a previously y touched point.  SHPIX additionally
+     *   denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+     *   Both instructions are commonly used to `fix' pixel patterns for
+     *   monochrome or Windows's GDI rendering but make little sense for
+     *   FreeType rendering.  Both can distort the outline.  See [2] for
+     *   details.
+     *
+     * - The hdmx table and modifications to phantom points are ignored.
+     *   Bearings and advance widths remain unchanged (except rounding them
+     *   outside the interpreter!), cf. `compute_glyph_metrics' and
+     *   `TT_Hint_Glyph'.  Letting non-native-ClearType fonts modify spacing
+     *   might mess up spacing.
+     *
+     * Minor hacks
+     *
+     * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP.  This
+     *   prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+     *   various sizes.
+     *
+     * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+     * executed.)
+     *
+     * The best results are achieved for fonts that were from the outset
+     * designed with ClearType in mind, meaning they leave the x axis mostly
+     * alone and don't mess with the `final' outline to produce more
+     * pleasing pixel patterns.  The harder the designer tried to produce
+     * very specific patterns (`superhinting') for pre-ClearType-displays,
+     * the worse the results.
+     *
+     * Microsoft defines a way to turn off backwards compatibility and
+     * interpret instructions as before (called `native ClearType')[2][3].
+     * The font designer then regains full control and is responsible for
+     * making the font work correctly with ClearType without any
+     * hand-holding by the interpreter or rasterizer[4].  The v40
+     * interpreter assumes backwards compatibility by default, which can be
+     * turned off the same way by executing the following in the control
+     * program (cf. `Ins_INSTCTRL').
+     *
+     *   #PUSH 4,3
+     *   INSTCTRL[]
+     *
+     * [1] Tricky fonts as FreeType defines them rely on the bytecode
+     *     interpreter to display correctly.  Hacks can interfere with them,
+     *     so they get treated like native ClearType fonts (v40 with
+     *     backwards compatibility turned off).  Cf. `TT_RunIns'.
+     *
+     * [2] Proposed by Microsoft's Greg Hitchcock in
+     *     https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+     *
+     * [3] Beat Stamm describes it in more detail:
+     *     http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
+     *
+     * [4] The list of `native ClearType' fonts is small at the time of this
+     *     writing; I found the following on a Windows 10 Update 1511
+     *     installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+     *     JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+     *     SimSun, NSimSun, and Yu Gothic.

+        extra field (variable size)
+
+  B.  Data descriptor:
+
+        crc-32                          4 bytes
+        compressed size                 4 bytes
+        uncompressed size               4 bytes
+
+      This descriptor exists only if bit 3 of the general
+      purpose bit flag is set (see below).  It is byte aligned
+      and immediately follows the last byte of compressed data.
+      This descriptor is used only when it was not possible to
+      seek in the output zip file, e.g., when the output zip file
+      was standard output or a non seekable device.

+        zipfile comment (variable size)
+
+  D.  Explanation of fields:
+
+      version made by (2 bytes)
+
+          The upper byte indicates the compatibility of the file
+          attribute information.  If the external file attributes 
+          are compatible with MS-DOS and can be read by PKZIP for 
+          DOS version 2.04g then this value will be zero.  If these 
+          attributes are not compatible, then this value will 
+          identify the host system on which the attributes are 
+          compatible.  Software can use this information to determine
+          the line record format for text files etc.  The current
+          mappings are:
+
+          0 - MS-DOS and OS/2 (FAT / VFAT / FAT32 file systems)
+          1 - Amiga                     2 - VAX/VMS
+          3 - Unix                      4 - VM/CMS
+          5 - Atari ST                  6 - OS/2 H.P.F.S.
+          7 - Macintosh                 8 - Z-System
+          9 - CP/M                     10 - Windows NTFS
+         11 thru 255 - unused
+
+          The lower byte indicates the version number of the
+          software used to encode the file.  The value/10
+          indicates the major version number, and the value
+          mod 10 is the minor version number.
+
+      version needed to extract (2 bytes)
+
+          The minimum software version needed to extract the
+          file, mapped as above.
+
+      general purpose bit flag: (2 bytes)
+
+          Bit 0: If set, indicates that the file is encrypted.
+
+          (For Method 6 - Imploding)
+          Bit 1: If the compression method used was type 6,
+                 Imploding, then this bit, if set, indicates
+                 an 8K sliding dictionary was used.  If clear,
+                 then a 4K sliding dictionary was used.
+          Bit 2: If the compression method used was type 6,
+                 Imploding, then this bit, if set, indicates
+                 3 Shannon-Fano trees were used to encode the
+                 sliding dictionary output.  If clear, then 2
+                 Shannon-Fano trees were used.
+
+          (For Method 8 - Deflating)
+          Bit 2  Bit 1
+            0      0    Normal (-en) compression option was used.
+            0      1    Maximum (-ex) compression option was used.
+            1      0    Fast (-ef) compression option was used.
+            1      1    Super Fast (-es) compression option was used.
+
+          Note:  Bits 1 and 2 are undefined if the compression
+                 method is any other.
+
+          Bit 3: If this bit is set, the fields crc-32, compressed 
+                 size and uncompressed size are set to zero in the 
+                 local header.  The correct values are put in the 
+                 data descriptor immediately following the compressed
+                 data.  (Note: PKZIP version 2.04g for DOS only 
+                 recognizes this bit for method 8 compression, newer 
+                 versions of PKZIP recognize this bit for any 
+                 compression method.)
+
+          Bit 4: Reserved for use with method 8, for enhanced
+                 deflating. 
+
+          Bit 5: If this bit is set, this indicates that the file is 
+                 compressed patched data.  (Note: Requires PKZIP 
+                 version 2.70 or greater)
+
+          Bit 6: Currently unused.
+
+          Bit 7: Currently unused.
+
+          Bit 8: Currently unused.
+
+          Bit 9: Currently unused.
+
+          Bit 10: Currently unused.
+
+          Bit 11: Currently unused.
+
+          Bit 12: Reserved by PKWARE for enhanced compression.
+
+          Bit 13: Reserved by PKWARE.
+
+          Bit 14: Reserved by PKWARE.
+
+          Bit 15: Reserved by PKWARE.
+
+      compression method: (2 bytes)
+
+          (see accompanying documentation for algorithm
+          descriptions)
+
+          0 - The file is stored (no compression)
+          1 - The file is Shrunk
+          2 - The file is Reduced with compression factor 1
+          3 - The file is Reduced with compression factor 2
+          4 - The file is Reduced with compression factor 3
+          5 - The file is Reduced with compression factor 4
+          6 - The file is Imploded
+          7 - Reserved for Tokenizing compression algorithm
+          8 - The file is Deflated
+          9 - Reserved for enhanced Deflating
+         10 - PKWARE Date Compression Library Imploding
+
+      date and time fields: (2 bytes each)
+
+          The date and time are encoded in standard MS-DOS format.
+          If input came from standard input, the date and time are
+          those at which compression was started for this data.
+
+      CRC-32: (4 bytes)
+
+          The CRC-32 algorithm was generously contributed by
+          David Schwaderer and can be found in his excellent
+          book "C Programmers Guide to NetBIOS" published by
+          Howard W. Sams & Co. Inc.  The 'magic number' for
+          the CRC is 0xdebb20e3.  The proper CRC pre and post
+          conditioning is used, meaning that the CRC register
+          is pre-conditioned with all ones (a starting value
+          of 0xffffffff) and the value is post-conditioned by
+          taking the one's complement of the CRC residual.
+          If bit 3 of the general purpose flag is set, this
+          field is set to zero in the local header and the correct
+          value is put in the data descriptor and in the central
+          directory.
+
+      compressed size: (4 bytes)
+      uncompressed size: (4 bytes)
+
+          The size of the file compressed and uncompressed,
+          respectively.  If bit 3 of the general purpose bit flag
+          is set, these fields are set to zero in the local header
+          and the correct values are put in the data descriptor and
+          in the central directory.
+
+      filename length: (2 bytes)
+      extra field length: (2 bytes)
+      file comment length: (2 bytes)
+
+          The length of the filename, extra field, and comment
+          fields respectively.  The combined length of any
+          directory record and these three fields should not
+          generally exceed 65,535 bytes.  If input came from standard
+          input, the filename length is set to zero.
+
+      disk number start: (2 bytes)
+
+          The number of the disk on which this file begins.
+
+      internal file attributes: (2 bytes)
+
+          The lowest bit of this field indicates, if set, that
+          the file is apparently an ASCII or text file.  If not
+          set, that the file apparently contains binary data.
+          The remaining bits are unused in version 1.0.
+
+          Bits 1 and 2 are reserved for use by PKWARE.
+
+      external file attributes: (4 bytes)
+
+          The mapping of the external attributes is
+          host-system dependent (see 'version made by').  For
+          MS-DOS, the low order byte is the MS-DOS directory
+          attribute byte.  If input came from standard input, this
+          field is set to zero.
+
+      relative offset of local header: (4 bytes)
+
+          This is the offset from the start of the first disk on
+          which this file appears, to where the local header should
+          be found.
+
+      filename: (Variable)
+
+          The name of the file, with optional relative path.
+          The path stored should not contain a drive or
+          device letter, or a leading slash.  All slashes
+          should be forward slashes '/' as opposed to
+          backwards slashes '\' for compatibility with Amiga
+          and Unix file systems etc.  If input came from standard
+          input, there is no filename field.
+
+      extra field: (Variable)
+
+          This is for future expansion.  If additional information
+          needs to be stored in the future, it should be stored
+          here.  Earlier versions of the software can then safely
+          skip this file, and find the next file or header.  This
+          field will be 0 length in version 1.0.
+
+          In order to allow different programs and different types
+          of information to be stored in the 'extra' field in .ZIP
+          files, the following structure should be used for all
+          programs storing data in this field:
+
+          header1+data1 + header2+data2 . . .
+
+          Each header should consist of:
+
+            Header ID - 2 bytes
+            Data Size - 2 bytes
+
+          Note: all fields stored in Intel low-byte/high-byte order.
+
+          The Header ID field indicates the type of data that is in
+          the following data block.
+
+          Header ID's of 0 thru 31 are reserved for use by PKWARE.
+          The remaining ID's can be used by third party vendors for
+          proprietary usage.
+
+          The current Header ID mappings defined by PKWARE are:
+
+          0x0007        AV Info
+          0x0009        OS/2
+          0x000a        NTFS 
+          0x000c        VAX/VMS
+          0x000d        Unix
+          0x000f        Patch Descriptor
+
+          Several third party mappings commonly used are:
+
+          0x4b46        FWKCS MD5 (see below)
+          0x07c8        Macintosh
+          0x4341        Acorn/SparkFS 
+          0x4453        Windows NT security descriptor (binary ACL)
+          0x4704        VM/CMS
+          0x470f        MVS
+          0x4c41        OS/2 access control list (text ACL)
+          0x4d49        Info-ZIP VMS (VAX or Alpha)
+          0x5455        extended timestamp
+          0x5855        Info-ZIP Unix (original, also OS/2, NT, etc)
+          0x6542        BeOS/BeBox
+          0x756e        ASi Unix
+          0x7855        Info-ZIP Unix (new)
+          0xfd4a        SMS/QDOS
+
+          The Data Size field indicates the size of the following
+          data block. Programs can use this value to skip to the
+          next header block, passing over any data blocks that are
+          not of interest.
+
+          Note: As stated above, the size of the entire .ZIP file
+                header, including the filename, comment, and extra
+                field should not exceed 64K in size.
+
+          In case two different programs should appropriate the same
+          Header ID value, it is strongly recommended that each
+          program place a unique signature of at least two bytes in
+          size (and preferably 4 bytes or bigger) at the start of
+          each data area.  Every program should verify that its
+          unique signature is present, in addition to the Header ID
+          value being correct, before assuming that it is a block of
+          known type.
+
+         -OS/2 Extra Field:
+
+          The following is the layout of the OS/2 attributes "extra" 
+          block.  (Last Revision  09/05/95)
+
+          Note: all fields stored in Intel low-byte/high-byte order.
+
+          Value       Size          Description
+          -----       ----          -----------
+  (OS/2)  0x0009      2 bytes       Tag for this "extra" block type
+          TSize       2 bytes       Size for the following data block
+          BSize       4 bytes       Uncompressed Block Size
+          CType       2 bytes       Compression type
+          EACRC       4 bytes       CRC value for uncompress block
+          (var)       variable      Compressed block
+
+        The OS/2 extended attribute structure (FEA2LIST) is 
+        compressed and then stored in it's entirety within this 
+        structure.  There will only ever be one "block" of data in 
+        VarFields[].
+
+         -UNIX Extra Field:
+
+          The following is the layout of the Unix "extra" block.
+          Note: all fields are stored in Intel low-byte/high-byte 
+          order.
+
+          Value       Size          Description
+          -----       ----          -----------
+  (UNIX)  0x000d      2 bytes       Tag for this "extra" block type
+          TSize       2 bytes       Size for the following data block
+          Atime       4 bytes       File last access time
+          Mtime       4 bytes       File last modification time
+          Uid         2 bytes       File user ID
+          Gid         2 bytes       File group ID
+          (var)       variable      Variable length data field
+
+          The variable length data field will contain file type 
+          specific data.  Currently the only values allowed are
+          the original "linked to" file names for hard or symbolic 
+          links.
+
+         -VAX/VMS Extra Field:
+
+          The following is the layout of the VAX/VMS attributes 
+          "extra" block.
+
+          Note: all fields stored in Intel low-byte/high-byte order.
+
+          Value      Size       Description
+          -----      ----       -----------
+  (VMS)   0x000c     2 bytes    Tag for this "extra" block type
+          TSize      2 bytes    Size of the total "extra" block
+          CRC        4 bytes    32-bit CRC for remainder of the block
+          Tag1       2 bytes    VMS attribute tag value #1
+          Size1      2 bytes    Size of attribute #1, in bytes
+          (var.)     Size1      Attribute #1 data
+          .
+          .
+          .
+          TagN       2 bytes    VMS attribute tage value #N
+          SizeN      2 bytes    Size of attribute #N, in bytes
+          (var.)     SizeN      Attribute #N data
+
+          Rules:
+
+          1. There will be one or more of attributes present, which 
+             will each be preceded by the above TagX & SizeX values.  
+             These values are identical to the ATR$C_XXXX and 
+             ATR$S_XXXX constants which are defined in ATR.H under 
+             VMS C.  Neither of these values will ever be zero.
+
+          2. No word alignment or padding is performed.
+
+          3. A well-behaved PKZIP/VMS program should never produce
+             more than one sub-block with the same TagX value.  Also,
+             there will never be more than one "extra" block of type
+             0x000c in a particular directory record.
+
+         -NTFS Extra Field:
+
+          The following is the layout of the NTFS attributes 
+          "extra" block.
+
+          Note: all fields stored in Intel low-byte/high-byte order.
+
+          Value      Size       Description

+          - FWKCS MD5 Extra Field:
+
+          The FWKCS Contents_Signature System, used in
+          automatically identifying files independent of filename,
+          optionally adds and uses an extra field to support the
+          rapid creation of an enhanced contents_signature:
+
+              Header ID = 0x4b46
+              Data Size = 0x0013
+              Preface   = 'M','D','5'
+              followed by 16 bytes containing the uncompressed file's
+              128_bit MD5 hash(1), low byte first.
+
+          When FWKCS revises a zipfile central directory to add
+          this extra field for a file, it also replaces the
+          central directory entry for that file's uncompressed
+          filelength with a measured value.
+
+          FWKCS provides an option to strip this extra field, if
+          present, from a zipfile central directory. In adding
+          this extra field, FWKCS preserves Zipfile Authenticity
+          Verification; if stripping this extra field, FWKCS
+          preserves all versions of AV through PKZIP version 2.04g.

+          length is given explicitly.
+
+      3)  Local headers should not span disk boundaries.  Also, even
+          though the central directory can span disk boundaries, no
+          single record in the central directory should be split
+          across disks.
+
+      4)  The entries in the central directory may not necessarily
+          be in the same order that files appear in the zipfile.
+
+UnShrinking - Method 1
+----------------------
+
+Shrinking is a Dynamic Ziv-Lempel-Welch compression algorithm
+with partial clearing.  The initial code size is 9 bits, and
+the maximum code size is 13 bits.  Shrinking differs from
+conventional Dynamic Ziv-Lempel-Welch implementations in several
+respects:
+
+1)  The code size is controlled by the compressor, and is not
+    automatically increased when codes larger than the current
+    code size are created (but not necessarily used).  When
+    the decompressor encounters the code sequence 256
+    (decimal) followed by 1, it should increase the code size
+    read from the input stream to the next bit size.  No
+    blocking of the codes is performed, so the next code at
+    the increased size should be read from the input stream
+    immediately after where the previous code at the smaller
+    bit size was read.  Again, the decompressor should not
+    increase the code size used until the sequence 256,1 is
+    encountered.
+
+2)  When the table becomes full, total clearing is not
+    performed.  Rather, when the compressor emits the code
+    sequence 256,2 (decimal), the decompressor should clear
+    all leaf nodes from the Ziv-Lempel tree, and continue to
+    use the current code size.  The nodes that are cleared
+    from the Ziv-Lempel tree are then re-used, with the lowest
+    code value re-used first, and the highest code value
+    re-used last.  The compressor can emit the sequence 256,2
+    at any time.
+
+Expanding - Methods 2-5
+-----------------------
+
+The Reducing algorithm is actually a combination of two
+distinct algorithms.  The first algorithm compresses repeated
+byte sequences, and the second algorithm takes the compressed
+stream from the first algorithm and applies a probabilistic
+compression method.
+
+The probabilistic compression stores an array of 'follower
+sets' S(j), for j=0 to 255, corresponding to each possible
+ASCII character.  Each set contains between 0 and 32
+characters, to be denoted as S(j)[0],...,S(j)[m], where m<32.
+The sets are stored at the beginning of the data area for a
+Reduced file, in reverse order, with S(255) first, and S(0)
+last.
+
+The sets are encoded as { N(j), S(j)[0],...,S(j)[N(j)-1] },
+where N(j) is the size of set S(j).  N(j) can be 0, in which
+case the follower set for S(j) is empty.  Each N(j) value is
+encoded in 6 bits, followed by N(j) eight bit character values
+corresponding to S(j)[0] to S(j)[N(j)-1] respectively.  If
+N(j) is 0, then no values for S(j) are stored, and the value
+for N(j-1) immediately follows.
+
+Immediately after the follower sets, is the compressed data
+stream.  The compressed data stream can be interpreted for the
+probabilistic decompression as follows:
+
+let Last-Character <- 0.
+loop until done
+    if the follower set S(Last-Character) is empty then
+        read 8 bits from the input stream, and copy this
+        value to the output stream.
+    otherwise if the follower set S(Last-Character) is non-empty then
+        read 1 bit from the input stream.
+        if this bit is not zero then
+            read 8 bits from the input stream, and copy this
+            value to the output stream.
+        otherwise if this bit is zero then
+            read B(N(Last-Character)) bits from the input
+            stream, and assign this value to I.
+            Copy the value of S(Last-Character)[I] to the
+            output stream.
+
+    assign the last value placed on the output stream to
+    Last-Character.
+end loop
+
+B(N(j)) is defined as the minimal number of bits required to
+encode the value N(j)-1.
+
+The decompressed stream from above can then be expanded to
+re-create the original file as follows:
+
+let State <- 0.
+
+loop until done
+    read 8 bits from the input stream into C.
+    case State of
+        0:  if C is not equal to DLE (144 decimal) then
+                copy C to the output stream.
+            otherwise if C is equal to DLE then
+                let State <- 1.
+
+        1:  if C is non-zero then
+                let V <- C.
+                let Len <- L(V)
+                let State <- F(Len).
+            otherwise if C is zero then
+                copy the value 144 (decimal) to the output stream.
+                let State <- 0
+
+        2:  let Len <- Len + C
+            let State <- 3.
+
+        3:  move backwards D(V,C) bytes in the output stream
+            (if this position is before the start of the output
+            stream, then assume that all the data before the
+            start of the output stream is filled with zeros).
+            copy Len+3 bytes from this position to the output stream.
+            let State <- 0.
+    end case
+end loop
+
+The functions F,L, and D are dependent on the 'compression
+factor', 1 through 4, and are defined as follows:
+
+For compression factor 1:
+    L(X) equals the lower 7 bits of X.
+    F(X) equals 2 if X equals 127 otherwise F(X) equals 3.
+    D(X,Y) equals the (upper 1 bit of X) * 256 + Y + 1.
+For compression factor 2:
+    L(X) equals the lower 6 bits of X.
+    F(X) equals 2 if X equals 63 otherwise F(X) equals 3.
+    D(X,Y) equals the (upper 2 bits of X) * 256 + Y + 1.
+For compression factor 3:
+    L(X) equals the lower 5 bits of X.
+    F(X) equals 2 if X equals 31 otherwise F(X) equals 3.
+    D(X,Y) equals the (upper 3 bits of X) * 256 + Y + 1.
+For compression factor 4:
+    L(X) equals the lower 4 bits of X.
+    F(X) equals 2 if X equals 15 otherwise F(X) equals 3.
+    D(X,Y) equals the (upper 4 bits of X) * 256 + Y + 1.
+
+Imploding - Method 6
+--------------------
+
+The Imploding algorithm is actually a combination of two distinct
+algorithms.  The first algorithm compresses repeated byte
+sequences using a sliding dictionary.  The second algorithm is
+used to compress the encoding of the sliding dictionary output,
+using multiple Shannon-Fano trees.
+
+The Imploding algorithm can use a 4K or 8K sliding dictionary
+size. The dictionary size used can be determined by bit 1 in the
+general purpose flag word; a 0 bit indicates a 4K dictionary
+while a 1 bit indicates an 8K dictionary.
+
+The Shannon-Fano trees are stored at the start of the compressed
+file. The number of trees stored is defined by bit 2 in the
+general purpose flag word; a 0 bit indicates two trees stored, a
+1 bit indicates three trees are stored.  If 3 trees are stored,
+the first Shannon-Fano tree represents the encoding of the
+Literal characters, the second tree represents the encoding of
+the Length information, the third represents the encoding of the
+Distance information.  When 2 Shannon-Fano trees are stored, the
+Length tree is stored first, followed by the Distance tree.
+
+The Literal Shannon-Fano tree, if present is used to represent
+the entire ASCII character set, and contains 256 values.  This
+tree is used to compress any data not compressed by the sliding
+dictionary algorithm.  When this tree is present, the Minimum
+Match Length for the sliding dictionary is 3.  If this tree is
+not present, the Minimum Match Length is 2.
+
+The Length Shannon-Fano tree is used to compress the Length part
+of the (length,distance) pairs from the sliding dictionary
+output.  The Length tree contains 64 values, ranging from the
+Minimum Match Length, to 63 plus the Minimum Match Length.
+
+The Distance Shannon-Fano tree is used to compress the Distance
+part of the (length,distance) pairs from the sliding dictionary
+output. The Distance tree contains 64 values, ranging from 0 to
+63, representing the upper 6 bits of the distance value.  The
+distance values themselves will be between 0 and the sliding
+dictionary size, either 4K or 8K.
+
+The Shannon-Fano trees themselves are stored in a compressed
+format. The first byte of the tree data represents the number of
+bytes of data representing the (compressed) Shannon-Fano tree
+minus 1.  The remaining bytes represent the Shannon-Fano tree
+data encoded as:
+
+    High 4 bits: Number of values at this bit length + 1. (1 - 16)
+    Low  4 bits: Bit Length needed to represent value + 1. (1 - 16)
+
+The Shannon-Fano codes can be constructed from the bit lengths
+using the following algorithm:
+
+1)  Sort the Bit Lengths in ascending order, while retaining the
+    order of the original lengths stored in the file.
+
+2)  Generate the Shannon-Fano trees:
+
+    Code <- 0
+    CodeIncrement <- 0
+    LastBitLength <- 0
+    i <- number of Shannon-Fano codes - 1   (either 255 or 63)
+
+    loop while i >= 0
+        Code = Code + CodeIncrement
+        if BitLength(i) <> LastBitLength then
+            LastBitLength=BitLength(i)
+            CodeIncrement = 1 shifted left (16 - LastBitLength)
+        ShannonCode(i) = Code
+        i <- i - 1
+    end loop
+
+3)  Reverse the order of all the bits in the above ShannonCode()
+    vector, so that the most significant bit becomes the least
+    significant bit.  For example, the value 0x1234 (hex) would
+    become 0x2C48 (hex).
+
+4)  Restore the order of Shannon-Fano codes as originally stored
+    within the file.
+
+Example:
+
+    This example will show the encoding of a Shannon-Fano tree
+    of size 8.  Notice that the actual Shannon-Fano trees used
+    for Imploding are either 64 or 256 entries in size.
+
+Example:   0x02, 0x42, 0x01, 0x13
+
+    The first byte indicates 3 values in this table.  Decoding the
+    bytes:
+            0x42 = 5 codes of 3 bits long
+            0x01 = 1 code  of 2 bits long
+            0x13 = 2 codes of 4 bits long
+
+    This would generate the original bit length array of:
+    (3, 3, 3, 3, 3, 2, 4, 4)
+
+    There are 8 codes in this table for the values 0 thru 7.  Using 
+    the algorithm to obtain the Shannon-Fano codes produces:
+
+                                  Reversed     Order     Original
+Val  Sorted   Constructed Code      Value     Restored    Length
+---  ------   -----------------   --------    --------    ------
+0:     2      1100000000000000        11       101          3
+1:     3      1010000000000000       101       001          3
+2:     3      1000000000000000       001       110          3
+3:     3      0110000000000000       110       010          3
+4:     3      0100000000000000       010       100          3
+5:     3      0010000000000000       100        11          2
+6:     4      0001000000000000      1000      1000          4
+7:     4      0000000000000000      0000      0000          4
+
+The values in the Val, Order Restored and Original Length columns
+now represent the Shannon-Fano encoding tree that can be used for
+decoding the Shannon-Fano encoded data.  How to parse the
+variable length Shannon-Fano values from the data stream is beyond
+the scope of this document.  (See the references listed at the end of
+this document for more information.)  However, traditional decoding
+schemes used for Huffman variable length decoding, such as the
+Greenlaw algorithm, can be successfully applied.
+
+The compressed data stream begins immediately after the
+compressed Shannon-Fano data.  The compressed data stream can be
+interpreted as follows:
+
+loop until done
+    read 1 bit from input stream.
+
+    if this bit is non-zero then       (encoded data is literal data)
+        if Literal Shannon-Fano tree is present
+            read and decode character using Literal Shannon-Fano tree.
+        otherwise
+            read 8 bits from input stream.
+        copy character to the output stream.
+    otherwise              (encoded data is sliding dictionary match)
+        if 8K dictionary size
+            read 7 bits for offset Distance (lower 7 bits of offset).
+        otherwise
+            read 6 bits for offset Distance (lower 6 bits of offset).
+
+        using the Distance Shannon-Fano tree, read and decode the
+          upper 6 bits of the Distance value.
+
+        using the Length Shannon-Fano tree, read and decode
+          the Length value.
+
+        Length <- Length + Minimum Match Length
+
+        if Length = 63 + Minimum Match Length
+            read 8 bits from the input stream,
+            add this value to Length.
+
+        move backwards Distance+1 bytes in the output stream, and
+        copy Length characters from this position to the output
+        stream.  (if this position is before the start of the output
+        stream, then assume that all the data before the start of
+        the output stream is filled with zeros).

+
+Tokenizing - Method 7
+--------------------
+
+This method is not used by PKZIP.
+
+Deflating - Method 8
+-----------------
+
+The Deflate algorithm is similar to the Implode algorithm using
+a sliding dictionary of up to 32K with secondary compression
+from Huffman/Shannon-Fano codes.
+
+The compressed data is stored in blocks with a header describing
+the block and the Huffman codes used in the data block.  The header
+format is as follows:
+
+   Bit 0: Last Block bit     This bit is set to 1 if this is the last
+                             compressed block in the data.
+   Bits 1-2: Block type
+      00 (0) - Block is stored - All stored data is byte aligned.
+               Skip bits until next byte, then next word = block 
+               length, followed by the ones compliment of the block
+               length word. Remaining data in block is the stored 
+               data.
+
+      01 (1) - Use fixed Huffman codes for literal and distance codes.

+
+Expanding Huffman Codes
+-----------------------
+If the data block is stored with dynamic Huffman codes, the Huffman
+codes are sent in the following compressed format:
+
+   5 Bits: # of Literal codes sent - 256 (256 - 286)
+           All other codes are never sent.
+   5 Bits: # of Dist codes - 1           (1 - 32)
+   4 Bits: # of Bit Length codes - 3     (3 - 19)
+
+The Huffman codes are sent as bit lengths and the codes are built as
+described in the implode algorithm.  The bit lengths themselves are
+compressed with Huffman codes.  There are 19 bit length codes:
+
+   0 - 15: Represent bit lengths of 0 - 15
+       16: Copy the previous bit length 3 - 6 times.
+           The next 2 bits indicate repeat length (0 = 3, ... ,3 = 6)
+              Example:  Codes 8, 16 (+2 bits 11), 16 (+2 bits 10) will
+                        expand to 12 bit lengths of 8 (1 + 6 + 5)
+       17: Repeat a bit length of 0 for 3 - 10 times. (3 bits of length)
+       18: Repeat a bit length of 0 for 11 - 138 times (7 bits of length)
+
+The lengths of the bit length codes are sent packed 3 bits per value
+(0 - 7) in the following order:
+
+   16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
+
+The Huffman codes should be built as described in the Implode algorithm
+except codes are assigned starting at the shortest bit length, i.e. the
+shortest code should be all 0's rather than all 1's.  Also, codes with
+a bit length of zero do not participate in the tree construction.  The
+codes are then used to decode the bit lengths for the literal and 
+distance tables.
+
+The bit lengths for the literal tables are sent first with the number
+of entries sent described by the 5 bits sent earlier.  There are up
+to 286 literal characters; the first 256 represent the respective 8
+bit character, code 256 represents the End-Of-Block code, the remaining
+29 codes represent copy lengths of 3 thru 258.  There are up to 30
+distance codes representing distances from 1 thru 32k as described
+below.
+

+
+Decryption
+----------
+
+The encryption used in PKZIP was generously supplied by Roger
+Schlafly.  PKWARE is grateful to Mr. Schlafly for his expert
+help and advice in the field of data encryption.
+
+PKZIP encrypts the compressed data stream.  Encrypted files must
+be decrypted before they can be extracted.
+
+Each encrypted file has an extra 12 bytes stored at the start of
+the data area defining the encryption header for that file.  The
+encryption header is originally set to random values, and then
+itself encrypted, using three, 32-bit keys.  The key values are
+initialized using the supplied encryption password.  After each byte
+is encrypted, the keys are then updated using pseudo-random number
+generation techniques in combination with the same CRC-32 algorithm
+used in PKZIP and described elsewhere in this document.
+
+The following is the basic steps required to decrypt a file:
+
+1) Initialize the three 32-bit keys with the password.
+2) Read and decrypt the 12-byte encryption header, further
+   initializing the encryption keys.
+3) Read and decrypt the compressed data stream using the
+   encryption keys.
+
+Step 1 - Initializing the encryption keys
+-----------------------------------------
+
+Key(0) <- 305419896
+Key(1) <- 591751049
+Key(2) <- 878082192
+
+loop for i <- 0 to length(password)-1
+    update_keys(password(i))
+end loop
+
+Where update_keys() is defined as:
+
+update_keys(char):
+  Key(0) <- crc32(key(0),char)
+  Key(1) <- Key(1) + (Key(0) & 000000ffH)
+  Key(1) <- Key(1) * 134775813 + 1
+  Key(2) <- crc32(key(2),key(1) >> 24)
+end update_keys
+
+Where crc32(old_crc,char) is a routine that given a CRC value and a
+character, returns an updated CRC value after applying the CRC-32
+algorithm described elsewhere in this document.
+
+Step 2 - Decrypting the encryption header
+-----------------------------------------
+
+The purpose of this step is to further initialize the encryption
+keys, based on random data, to render a plaintext attack on the
+data ineffective.
+
+Read the 12-byte encryption header into Buffer, in locations
+Buffer(0) thru Buffer(11).
+
+loop for i <- 0 to 11
+    C <- buffer(i) ^ decrypt_byte()
+    update_keys(C)
+    buffer(i) <- C
+end loop
+
+Where decrypt_byte() is defined as:
+
+unsigned char decrypt_byte()
+    local unsigned short temp
+    temp <- Key(2) | 2
+    decrypt_byte <- (temp * (temp ^ 1)) >> 8
+end decrypt_byte
+
+After the header is decrypted,  the last 1 or 2 bytes in Buffer
+should be the high-order word/byte of the CRC for the file being
+decrypted, stored in Intel low-byte/high-byte order.  Versions of
+PKZIP prior to 2.0 used a 2 byte CRC check; a 1 byte CRC check is
+used on versions after 2.0.  This can be used to test if the password
+supplied is correct or not.
+
+Step 3 - Decrypting the compressed data stream
+----------------------------------------------
+
+The compressed data stream can be decrypted as follows:
+
+loop until done
+    read a character into C
+    Temp <- C ^ decrypt_byte()
+    update_keys(temp)
+    output Temp
+end loop
+
+In addition to the above mentioned contributors to PKZIP and PKUNZIP,
+I would like to extend special thanks to Robert Mahoney for suggesting
+the extension .ZIP for this software.

+     *           respectively.  (In the former case, the behavior specified for
+     *           '[^az]' will happen.)

+     *           character represented by 'a' having a lower ASCII value than

+     *   o [^az] matches any character except a or z.  If ] is to appear inside
+     *           the brackets as a character to not match, it must be escaped.
+     *   o pat~pat2 returns matches to the pattern 'pat' which do not also match
+     *              the pattern 'pat2'.  This may be used to perform filtering
+     *              upon the results of one pattern to remove all matches which

+     *              'z', '*~*z*' will match all strings except those containing
+     *              a 'z'.  Note that a pattern may not use '~' multiple times,
+     *              so a string such as '*~*z*~*y*' is not a valid pattern.
+     *   o (foo|bar) will match either the pattern foo or the pattern bar.
+     *               Neither of the patterns foo or bar may use the 'pat~pat2'
+     *               syntax described immediately above.
+     *   o \ will escape a special character.  Escaping is required for all
+     *       special characters unless otherwise specified.
+     *   o All other characters match case-sensitively.
+     *
+     *   An aPattern not conforming to this syntax has undefined behavior.

+   *                  addObserver("foo.bar.", ...) will observe changes to
+   *                  foo.bar.baz and foo.bar.bzip
+   * @param aObserver The object to be notified if the preference changes.
+   * @param aHoldWeak true  Hold a weak reference to |aObserver|. The object
+   *                        must implement the nsISupportsWeakReference

+   *                  false Hold a strong reference to |aObserver|.
+   *
+   * @note
+   * Registering as a preference observer can open an object to potential
+   * cyclical references which will cause memory leaks. These cycles generally
+   * occur because an object both registers itself as an observer (causing the
+   * branch to hold a reference to the observer) and holds a reference to the
+   * branch object for the purpose of getting/setting preference values. There
+   * are 3 approaches which have been implemented in an attempt to avoid these
+   * situations.
+   * 1) The nsPrefBranch object supports nsISupportsWeakReference. Any consumer
+   *    may hold a weak reference to it instead of a strong one.
+   * 2) The nsPrefBranch object listens for xpcom-shutdown and frees all of the
+   *    objects currently in its observer list. This ensures that long lived
+   *    objects (services for example) will be freed correctly.
+   * 3) The observer can request to be held as a weak reference when it is
+   *    registered. This insures that shorter lived objects (say one tied to an
+   *    open window) will not fall into the cyclical reference trap.
+   *
+   * @note
+   * The list of registered observers may be changed during the dispatch of
+   * nsPref:changed notification. However, the observers are not guaranteed
+   * to be notified in any particular order, so you can't be sure whether the
+   * added/removed observer will be called during the notification when it
+   * is added/removed.
+   *
+   * @note
+   * It is possible to change preferences during the notification.
+   *
+   * @note
+   * It is not safe to change observers during this callback in Gecko 
+   * releases before 1.9. If you want a safe way to remove a pref observer,

+ *                          that the header CRC32 matches, but the header
+ *                          itself specifies something that we don't support.
+ * @XZ_DATA_ERROR:          Compressed data is corrupt.
+ * @XZ_BUF_ERROR:           Cannot make any progress. Details are slightly

+ *                          mode; more information below.
+ *
+ * In multi-call mode, XZ_BUF_ERROR is returned when two consecutive calls
+ * to XZ code cannot consume any input and cannot produce any new output.
+ * This happens when there is no new input available, or the output buffer
+ * is full while at least one output byte is still pending. Assuming your
+ * code is not buggy, you can get this error only when decoding a compressed

+ * Because the output buffer is used as the workspace, streams encoded using
+ * a big dictionary are not a problem in single-call mode. It is enough that
+ * the output buffer is big enough to hold the actual uncompressed data; it
+ * can be smaller than the dictionary size stored in the stream headers.

+ * dict_max specifies the maximum allowed dictionary size that xz_dec_run()
+ * may allocate once it has parsed the dictionary size from the stream
+ * headers. This way excessive allocations can be avoided while still
+ * limiting the maximum memory usage to a sane value to prevent running the
+ * system out of memory when decompressing streams from untrusted sources.
+ *

+  avail_out as zero but there is nothing to do
+- added memcmp for non STDC compilers

+
+                Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+http://zlib.net/ which may have more recent information.
+The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+    Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+    The zlib sources can be compiled without change to produce a DLL.  See the
+    file win32/DLL_FAQ.txt in the zlib distribution.  Pointers to the
+    precompiled DLL are found in the zlib web site at http://zlib.net/ .
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+    See
+        * http://marknelson.us/1997/01/01/zlib-engine/
+        * win32/DLL_FAQ.txt in the zlib distribution
+
+ 4. compress() returns Z_BUF_ERROR.
+
+    Make sure that before the call of compress(), the length of the compressed
+    buffer is equal to the available size of the compressed buffer and not
+    zero.  For Visual Basic, check that this parameter is passed by reference
+    ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+    Before making the call, make sure that avail_in and avail_out are not zero.
+    When setting the parameter flush equal to Z_FINISH, also make sure that
+    avail_out is big enough to allow processing all pending input.  Note that a
+    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
+    made with more input or output space.  A Z_BUF_ERROR may in fact be
+    unavoidable depending on how the functions are used, since it is not
+    possible to tell whether or not there is more output pending when
+    strm.avail_out returns with zero.  See http://zlib.net/zlib_how.html for a
+    heavily annotated example.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+    It's in zlib.h .  Examples of zlib usage are in the files test/example.c
+    and test/minigzip.c, with more in examples/ .
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+    Because we would like to keep zlib as a very small and simple package.
+    zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+    Most of the time, such problems are due to an incorrect usage of zlib.
+    Please try to reproduce the problem with a small program and send the
+    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
+    data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+    If "make test" produces something like
+
+       example.o(.text+0x154): undefined reference to `gzputc'
+
+    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+    /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+    See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+    Not by itself, no.  See the directory contrib/minizip in the zlib
+    distribution.
+
+12. Can zlib handle .Z files?
+
+    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
+    the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+    By default a shared (and a static) library is built for Unix.  So:
+
+    make distclean
+    ./configure
+    make
+
+14. How do I install a shared zlib library on Unix?
+
+    After the above, then:
+
+    make install
+
+    However, many flavors of Unix come with a shared zlib already installed.
+    Before going to the trouble of compiling a shared version of zlib and
+    trying to install it, you may want to check if it's already there!  If you
+    can #include <zlib.h>, it's there.  The -lz option will probably link to
+    it.  You can check the version at the top of zlib.h or with the
+    ZLIB_VERSION symbol defined in zlib.h .
+
+15. I have a question about OttoPDF.
+
+    We are not the authors of OttoPDF. The real author is on the OttoPDF web
+    site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+    Yes. See http://www.pdflib.com/ . To modify PDF forms, see
+    http://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+    generates an error such as:
+
+        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+        symbol __register_frame_info: referenced symbol not found
+
+    The symbol __register_frame_info is not part of zlib, it is generated by
+    the C compiler (cc or gcc).  You must recompile applications using zlib
+    which have this problem.  This problem is specific to Solaris.  See
+    http://www.sunfreeware.com for Solaris versions of zlib and applications
+    using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+    The compress and deflate functions produce data in the zlib format, which
+    is different and incompatible with the gzip format.  The gz* functions in
+    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
+    use the same compressed data format internally, but have different headers
+    and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+    The gzip format was designed to retain the directory information about a
+    single file, such as the name and last modification date.  The zlib format
+    on the other hand was designed for in-memory and communication channel
+    applications, and has a much more compact header and trailer and uses a
+    faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+    You can request that deflate write the gzip format instead of the zlib
+    format using deflateInit2().  You can also request that inflate decode the
+    gzip format using inflateInit2().  Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+    Yes.  However any library routines that zlib uses and any application-
+    provided memory allocation routines must also be thread-safe.  zlib's gz*
+    functions use stdio library routines, and most of zlib's functions use the
+    library memory allocation routines by default.  zlib's *Init* functions
+    allow for the application to provide custom memory allocation routines.
+
+    Of course, you should only operate on any given zlib or gzip stream from a
+    single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+    Yes.  Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+    No.  Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+    what exactly do I need to do to meet that requirement?
+
+    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
+    particular, the final version number needs to be changed to "f", and an
+    identification string should be appended to ZLIB_VERSION.  Version numbers
+    x.x.x.f are reserved for modifications to zlib by others than the zlib
+    maintainers.  For example, if the version of the base zlib you are altering
+    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
+    update the version strings in deflate.c and inftrees.c.
+
+    For altered source distributions, you should also note the origin and
+    nature of the changes in zlib.h, as well as in ChangeLog and README, along
+    with the dates of the alterations.  The origin should include at least your
+    name (or your company's name), and an email address to contact for help or
+    issues with the library.
+
+    Note that distributing a compiled zlib library along with zlib.h and
+    zconf.h is also a source distribution, and so you should change
+    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+    in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+    exchange compressed data between them?
+
+    Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+    Yes.  It has been tested on 64-bit machines, and has no dependence on any
+    data types being limited to 32-bits in length.  If you have any
+    difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+    No.  The PKWare DCL uses a completely different compressed data format than
+    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
+    directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+    No, not without some preparation.  If when compressing you periodically use
+    Z_FULL_FLUSH, carefully write all the pending data at those points, and
+    keep an index of those locations, then you can start decompression at those
+    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
+    can significantly degrade compression.  Alternatively, you can scan a
+    deflate stream once to generate an index, and then use that index for
+    random access.  See examples/zran.c .
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+    It has in the past, but we have not heard of any recent evidence.  There
+    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
+    If you know of recent, successful applications of zlib on these operating
+    systems, please let us know.  Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at to
+    understand the deflate format?
+
+    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
+    contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+    As far as we know, no.  In fact, that was originally the whole point behind
+    zlib.  Look here for some more information:
+
+    http://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+    Yes.  inflate() and deflate() will process any amount of data correctly.
+    Each call of inflate() or deflate() is limited to input and output chunks
+    of the maximum value that can be stored in the compiler's "unsigned int"
+    type, but there is no limit to the number of chunks.  Note however that the
+    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
+    counters are provided as a convenience and are not used internally by
+    inflate() or deflate().  The application can easily set up its own counters
+    updated after each call of inflate() or deflate() to count beyond 4 GB.
+    compress() and uncompress() may be limited to 4 GB, since they operate in a
+    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
+    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
+
+    The word "may" appears several times above since there is a 4 GB limit only
+    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
+    64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+    The only one that we are aware of is potentially in gzprintf().  If zlib is
+    compiled to use sprintf() or vsprintf(), then there is no protection
+    against a buffer overflow of an 8K string space (or other value as set by
+    gzbuffer()), other than the caller of gzprintf() assuring that the output
+    will not exceed 8K.  On the other hand, if zlib is compiled to use
+    snprintf() or vsnprintf(), which should normally be the case, then there is
+    no vulnerability.  The ./configure script will display warnings if an
+    insecure variation of sprintf() will be used by gzprintf().  Also the
+    zlibCompileFlags() function will return information on what variant of
+    sprintf() is used by gzprintf().
+
+    If you don't have snprintf() or vsnprintf() and would like one, you can
+    find a portable implementation here:
+
+        http://www.ijs.si/software/snprintf/
+
+    Note that you should be using the most recent version of zlib.  Versions
+    1.1.3 and before were subject to a double-free vulnerability, and versions
+    1.2.1 and 1.2.2 were subject to an access exception when decompressing
+    invalid compressed data.
+
+34. Is there a Java version of zlib?
+
+    Probably what you want is to use zlib in Java. zlib is already included
+    as part of the Java SDK in the java.util.zip package. If you really want
+    a version of zlib written in the Java language, look on the zlib home
+    page for links: http://zlib.net/ .
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+    up to maximally-pedantic. Can't you guys write proper code?
+
+    Many years ago, we gave up attempting to avoid warnings on every compiler
+    in the universe.  It just got to be a waste of time, and some compilers
+    were downright silly as well as contradicted each other.  So now, we simply
+    make sure that the code always works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+    performing a conditional jump that depends on an uninitialized value.
+    Isn't that a bug?
+
+    No.  That is intentional for performance reasons, and the output of deflate
+    is not affected.  This only started showing up recently since zlib 1.2.x
+    uses malloc() by default for allocations, whereas earlier versions used
+    calloc(), which zeros out the allocated memory.  Even though the code was
+    correct, versions 1.2.4 and later was changed to not stimulate these
+    checkers.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+    data format?
+
+    Probably not. Look in the comp.compression FAQ for pointers to various
+    formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+    zlib doesn't support encryption.  The original PKZIP encryption is very
+    weak and can be broken with freely available programs.  To get strong
+    encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
+    compression.  For PKZIP compatible "encryption", look at
+    http://www.info-zip.org/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
+    probably have called the second one "zlib" instead to avoid confusion with
+    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
+    correctly points to the zlib specification in RFC 1950 for the "deflate"
+    transfer encoding, there have been reports of servers and browsers that
+    incorrectly produce or expect raw deflate data per the deflate
+    specification in RFC 1951, most notably Microsoft.  So even though the
+    "deflate" transfer encoding using the zlib format would be the more
+    efficient approach (and in fact exactly what the zlib format was designed
+    for), using the "gzip" transfer encoding is probably more reliable due to
+    an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+    Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+    No.  PKWare has apparently decided to keep that format proprietary, since
+    they have not documented it as they have previous compression formats.  In
+    any case, the compression improvements are so modest compared to other more
+    modern approaches, that it's not worth the effort to implement.
+
+41. I'm having a problem with the zip functions in zlib, can you help?
+
+    There are no zip functions in zlib.  You are probably using minizip by
+    Giles Vollant, which is found in the contrib directory of zlib.  It is not
+    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
+    files in there are not supported by the zlib authors.  You need to contact
+    the authors of the respective contribution for help.
+
+42. The match.asm code in contrib is under the GNU General Public License.
+    Since it's part of zlib, doesn't that mean that all of zlib falls under the
+    GNU GPL?
+
+    No.  The files in contrib are not part of zlib.  They were contributed by
+    other authors and are provided as a convenience to the user within the zlib
+    distribution.  Each item in contrib has its own license.
+
+43. Is zlib subject to export controls?  What is its ECCN?
+
+    zlib is not subject to export controls, and so is classified as EAR99.
+
+44. Can you please sign these lengthy legal documents and fax them back to us
+    so that we can use your software in our product?
+
+    No. Go away. Shoo.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.8 is a general purpose data compression library.  All the code is
+thread safe.  The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
+rfc1952 (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example
+of the library is given in the file test/example.c which also tests that
+the library is working correctly.  Another example is given in the file
+test/minigzip.c.  The compression library itself is composed of all source
+files in the root directory.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile.in.  In short "./configure; make test", and if that goes
+well, "make install" should work for most flavors of Unix.  For Windows, use
+one of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
+make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version.  The zlib home page is
+http://zlib.net/ .  Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
+issue of Dr.  Dobb's Journal; a copy of the article is available at
+http://marknelson.us/1997/01/01/zlib-engine/ .
+
+The changes made in version 1.2.8 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory contrib/ .
+
+zlib is available in Java using the java.util.zip package, documented at
+http://java.sun.com/developer/technicalArticles/Programming/compression/ .
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
+at CPAN (Comprehensive Perl Archive Network) sites, including
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://docs.python.org/library/zlib.html .
+
+zlib is built into tcl: http://wiki.tcl.tk/4610 .
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+  -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+  compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+  when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+  necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+  other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS or BEOS.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/

+  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
+  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The first table is simply the CRC of all possible eight bit values.  This is
+  all the information needed to generate CRCs on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.  The remaining tables
+  allow for word-at-a-time CRC calculation for both big-endian and little-
+  endian machines, where a word is four bytes.

+/*
+ *  ALGORITHM
+ *
+ *      The "deflation" process depends on being able to identify portions
+ *      of the input text which are identical to earlier input (within a
+ *      sliding window trailing behind the input currently being processed).
+ *
+ *      The most straightforward technique turns out to be the fastest for
+ *      most input files: try all possible matches and select the longest.
+ *      The key feature of this algorithm is that insertions into the string
+ *      dictionary are very simple and thus fast, and deletions are avoided
+ *      completely. Insertions are performed at each input character, whereas
+ *      string matches are performed only when the previous match ends. So it
+ *      is preferable to spend more time in matches to allow very fast string
+ *      insertions and avoid deletions. The matching algorithm for small
+ *      strings is inspired from that of Rabin & Karp. A brute force approach
+ *      is used to find longer strings when a small match has been found.
+ *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ *      (by Leonid Broukhis).
+ *         A previous version of this file used a more sophisticated algorithm
+ *      (by Fiala and Greene) which is guaranteed to run in linear amortized
+ *      time, but has a larger average cost, uses more memory and is patented.
+ *      However the F&G algorithm may be faster for some highly redundant
+ *      files if the parameter max_chain_length (described below) is too large.
+ *
+ *  ACKNOWLEDGEMENTS
+ *
+ *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ *      I found it in 'freeze' written by Leonid Broukhis.
+ *      Thanks to many people for bug reports and testing.

+   filled the window with output, or when it completes with data in the
+   window, it calls out() to write out the data.  The application must not

+   inflateBack() returns.
+
+   in() and out() are called with a descriptor parameter provided in the

+   information required to do the read or write, as well as accumulated
+   information on the input and output such as totals and check values.
+
+   in() should return zero on failure.  out() should return non-zero on
+   failure.  If either in() or out() fails, than inflateBack() returns a
+   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
+   was in() or out() that caused in the error.  Otherwise,  inflateBack()

+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2012 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       code lengths are lens[0..codes-1].  Each length corresponds to the

+       symbols by length from short to long, and retaining the symbol order
+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer

+       increases.  For the deflate format, these bits are stored backwards

+       decoding tables are built in the large loop below, the integer codes
+       are incremented backwards.
+

+
+       The codes are sorted by computing a count of codes for each length,
+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip streams in memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in case of corrupted input.

+/*
+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).  Some
+    output may be provided even if flush is not set.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed code
+  block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error.  After
+  deflate has returned Z_STREAM_END, the only possible operations on the stream
+  are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step.  In this case, avail_out must be at least the
+  value returned by deflateBound (see below).  Then deflate is guaranteed to
+  return Z_STREAM_END.  If not enough output space is provided, deflate will
+  not return Z_STREAM_END, and it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  In doubt, the data is considered
+  binary.  This field is only for information purposes and does not affect the
+  compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
+  (for example avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not
+  fatal, and deflate() can be called again with more input and more output
+  space to continue compressing.

+ZEXTERN int ZEXPORT inflate OF((z_streamp strm, int flush));
+/*
+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing will
+    resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.) The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained, so applications that need that information should
+  instead use raw inflate, see inflateInit2() below, or inflateBack() and
+  perform their own processing of the gzip header and trailer.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  producted so far.  The CRC-32 is checked against the gzip trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
+  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing.  If Z_DATA_ERROR is returned, the application may
+  then call inflateSync() to look for a good compression block if a partial
+  recovery of the data is desired.

+
+     This is another version of deflateInit with more compression options.  The
+   fields next_in, zalloc, zfree and opaque must be initialized before by the
+   caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+
+     The dictionary should consist of strings (byte sequences) that are likely

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the normal
+   behavior of inflate(), which expects either a zlib or gzip header and
+   trailer around the deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.) Note that inflateBack()
