+	ftoption.h and ftconfig.h are written directly without a redundant `-new'

-	Ensure used preprocessor symbols are defined (#49790).

+	in cmake-gui.
 
-	* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
-	include/freetype/config/ftconfig.h: Check `__GNUC__', `__IBMC__',
-	and `__SUNPRO_C' correctly.
+	Internal: Properties such as dependencies and include directories are now
+	privately set on the freetype library instead of globally.
+
+	The CPack definitions have been cleaned up, the `make dist' has been
+	removed. Source packages generated with CPack don't contain Autotools
+	files and aren't used by the maintainters anyway.
+
+	On Windows, src/base/ftver.rc is compiled to decorate the library with
+	version and copyright information.
+

-2016-12-15  Dave Arnold  <darnold@adobe.com>
-	    Werner Lemberg  <wl@gnu.org>
+	According to the CFF specification, charstrings can have up to 96 stem
+	hints. Due to hint replacement routines in Type 1 charstrings, some
+	glyphs are rejected by the Adobe engine, which implements the above
+	limit. This fix turns off hinting for such glyphs.

-	The font variation code.  All parts dependent on the GX code in the
-	`truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. 
-	In other words, you can still compile the `cff' module without
-	defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
-	support without font variation).

+	[type1] Add Adobe engine configuration.

+	[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'
+	  zlib-1.2.8\zlib.h(94): error C2054:
+	                         expected '(' to follow 'z_const'
+	  zlib-1.2.8\zlib.h(94): error C2085:
+	                         'msg': not in formal parameter list
+	  ...

+	                          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.
+	* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

+
+	`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph

+
+	It now supports both a normal build (`./configure && make') and a
+	development build (`make devel').
+
+	* src/tools/ftrandom/Makefile (VPATH): Set it so that

+
+	* src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better

+
+2016-09-03  Werner Lemberg  <wl@gnu.org>
+
+	[base] Avoid negative bitmap strike dimensions (#48985).
+
+	* src/base/ftobjs.c (FT_Open_Face): Check whether negation was
+	actually successful.  For example, this can fail for value

+
+2016-09-01  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Simplify span rendering more.
+
+	It turns out that there is significant cost associated with `FT_Span'
+	creation and calls to `gray_render_span' because it happens so
+	frequently. This removes these steps from our internal use but leaves
+	it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
+	is about 5%.
+
+	* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
+	migrated to...
+	(gray_hline): ... here.
+
+2016-08-30  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Streamline pixmap drawing a bit more.
+
+	Zero coverage is unlikely (1 out of 256) to warrant checking. This
+	gives 0.5% speed improvement in rendering simple glyphs.
+
+	* src/smooth/ftgrays.c (gray_hline, gray_render_span): Remove checks.
+
+2016-08-29  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Streamline pixmap drawing.
+
+	This gives 2% speed improvement in rendering simple glyphs.
+
+	* src/smooth/ftgrays.c (TPixmap): Reduced pixmap descriptor with a
+	pointer to its bottom-left and pitch to be used in...
+	(gray_TWorker): ... here.
+	(gray_render_span): Move pixmap flow check from here...
+	(gray_raster_render): .. to here.
+
+2016-08-27  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Reduce stack of band boundaries.
+
+	* src/smooth/ftgrays.c (gray_TBand): Removed.
+	(gray_convert_glyph): Updated to stack band boundaries concisely.
+
+2016-08-26  Werner Lemberg  <wl@gnu.org>

+
+	[cid] Fix commit from 2016-05-16.
+
+	* src/cid/cidparse.c (cid_parser_new): Fix off-by-one errors.
+
+2016-08-26  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt] Cache offset and size to bitmap data table.
+
+	This commit avoids `EBDT' and friends being looked up again and
+	again while loading a single embedded bitmap.
+
+	* include/freetype/internal/tttypes.h (TT_FaceRec)
+	[TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: New fields `ebdt_start' and
+	`ebdt_size'.
+
+	* src/sfnt/ttsbit.c (tt_sbit_decoder_init): Move table lookup to ...
+	(tt_face_load_sbit): ... this function; also store the table size
+	and offset.
+
+2016-08-26  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	* src/smooth/ftgrays.c (gray_raster_render): Minor tweaks.
+
+2016-08-26  Werner Lemberg  <wl@gnu.org>
+

+
+	Reported as
+
+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36
+
+	* src/type1/t1load.c (parse_charstrings): Reject fonts that don't
+	contain glyph names.
+
+2016-08-25  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt] Fix previous commit (#48901).

+
+2016-08-25  Werner Lemberg  <wl@gnu.org>
+
+	* include/freetype/internal/ftdriver.h: Remove unused typedefs.
+
+2016-08-22  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Simplify span rendering.
+
+	This removes unnecessary complexity of span merging and buffering.
+	Instead, the spans are rendered as they come, speeding up the
+	rendering by about 5% as a result.
+
+	* src/smooth/ftgrays.c [FT_MAX_GRAY_SPANS]: Macro removed.
+	(gray_TWorker): Remove span buffer and related fields.
+	(gray_sweep, gray_hline): Updated.
+
+	* include/freetype/ftimage.h: Remove documentation note about
+	`FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone.
+
+2016-08-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix `MPS' instruction.
+
+	According to Greg Hitchcock, MPS in DWrite really returns the point
+	size.
+

+
+	* src/truetype/ttdriver.c (tt_size_request): Set `point_size'.

+
+2016-08-16  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Fix compiler warning.

+
+	Reported as

+	  https://bugzilla.mozilla.org/show_bug.cgi?id=1272173
+
+	* src/winfonts/winfnt.c (FNT_Face_Init): Check zero pixel height.

+
+2016-08-10  Werner Lemberg  <wl@gnu.org>
+
+	[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>
+
+	[truetype] Fix GX variation handling of composites.
+

+	[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>

+	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.

+	(TT_RunIns): Updated.
+
+2016-07-17  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Add support for Apple's

+
+	* src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.

+	(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>

+
+2016-07-16  Behdad Esfahbod  <behdad@behdad.org>
+

+
+	This finally fixes the rendering of the cyclist and the lizard in

+
+	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point

+	(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.

+
+	* 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

+
+	[base] Remove a check for resource ID in the resource fork driver.
+
+	LastResort.dfont has a marginal resource ID 0xFFFF for sfnt
+	resource.  Inside Macintosh: More Macintosh Toolbox, `Resource IDs'
+	(1-46), tells that some IDs are reserved and should not be used.
+	FreeType2 just uses resource ID to sort the fragmented resource.
+	To accept the marginal fonts, the checking is removed.
+
+	* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id
+	validity check, fix a trace message format.
+
+2017-09-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
+
+	[sfnt, truetype] Register the tags for marginal fonts.
+
+	The first 32bit of standard TrueType variants is 0x00010000,
+	`OTTO', `ttcf', `true' or `typ1'.  2 marginal dfonts on legacy Mac
+	OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
+	starting 0xA5 followed by `kbd' or `lst'.  Considering the following
+	data could be parsed as conventional TrueType fonts, the header
+	checking is updated to allow these tags.  It seems that recent Mac
+	OS X has already switched to normal TTF for these fonts.
+
+	See the discussion at
+	http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
+
+	* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
+	tags for Keyboard.dfont and LastResort.dfont.
+	* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
+	starts with TTAG_0xA5kbd or TTAG_0xA5lst.
+	* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
+	format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
+
+2017-09-05  Werner Lemberg  <wl@gnu.org>
+
+	Fix multiple calls of `FT_Bitmap_Convert'.
+
+	The documentation of `FT_Bitmap_Convert' says that multiple calls do
+	proper reallocation of the target FT_Bitmap object.  However, this
+	failed for the sequence
+
+	  non-empty bitmap
+	  empty bitmap
+	  non-empty bitmap
+
+	Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
+	buffer if it became too small; it didn't make the buffer smaller.
+	For an empty bitmap following a non-empty one, only the buffer
+	dimension got set to zero, without deallocation.  If the next call
+	was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
+	triggered.
+
+	* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
+	buffer to the correct size.
+
+	* docs/CHANGES: Document it.
+
+2017-09-05  Werner Lemberg  <wl@gnu.org>
+
+	[bdf] Fix size and resolution handling.
+
+	* src/bdf/bdfdrivr.c (BDF_Face_Init): Use `SIZE' values if
+	`POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties are
+	missing.
+
+	* docs/CHANGES: Document it.
+
+2017-08-25  Alexei Podtelezhnikov  <apodtele@gmail.com>

+	Swap `ALLOC_MULT' arguments (#51833).
+
+	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Updated.

+
+	[sfnt] Fix clang compilation (#51788).
+
+	* src/sfnt/pngshim.c (premultiply_data): Use vectors instead of
+	scalars.
+	(vector_shuffle): New macro to take care of a different built-in
+	function name on clang.
+
+2017-08-22  Werner Lemberg  <wl@gnu.org>
+
+	[base] Don't zero out allocated memory twice (#51816).
+
+	Patch applied from bug report.
+
+	* src/base/ftutil.c (ft_mem_qrealloc): Use low-level allocation to
+	avoid unnecessary overhead.
+
+2017-08-22  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Integer overflow.
+
+	Changes triggered by
+
+	  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3107
+
+	* src/truetype/ttinterp.c (Ins_MDRP, Ins_MIRP, Ins_ALIGNPTS): Use

+
+	Reported as

+	  https://bugs.chromium.org/p/chromium/issues/detail?id=754574
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL.
+
+2017-08-16  Werner Lemberg  <wl@gnu.org>
+
+	* src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.
+
+2017-08-15  Behdad Esfahbod  <behdad@behdad.org>
+
+	[sfnt] Speed up PNG image loading.
+
+	This reduces the overhead of `premultiply_data' by 60%.
+
+	* src/sfnt/pngshim.c (premultiply_data): Provide code which uses
+	gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a
+	time.
+
+2017-08-11  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt, truetype] Improve handling of missing sbits.
+
+	Requested by Behdad.
+
+	Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
+	entries in the bitmap strike(s) for empty glyphs.  Instead, they
+	rely that a space glyph gets created from the font's metrics data.
+	This commit makes FreeType behave accordingly.
+
+	* include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
+	code.
+
+	* src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
+	to make a distinction between a missing bitmap in a composite and a
+	simple missing bitmap.
+
+	* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
+	bitmap-only font), synthesize an empty bitmap glyph if metrics are
+	available.
+
+2017-08-10  Werner Lemberg  <wl@gnu.org>
+
+	[base] Minor API improvement for default variation axis setting.
+
+	* src/base/ftmm.c (FT_Set_MM_Design_Coordinates,
+	FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,
+	FT_Set_Var_Blend_Coordinates): Allow coords==NULL if num_coords==0.
+
+	* docs/CHANGES: Updated.
+
+2017-08-08  Werner Lemberg  <wl@gnu.org>
+
+	[psnames] Really fix issue #49949.
+
+	We now use a separate preprocessor macro to handle both definition
+	and declaration of the glyph name arrays.
+
+	* src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.
+
+	* src/tools/glnames.py (StringTable::dump,
+	StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.
+	(dump_encoding): Ditto.
+	(main): Use `wb' mode for writing the output file, which works on
+	Windows also.
+
+	* src/psnames/pstables.h: Regenerated.
+
+2017-08-08  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	[smooth] Harmony LCD rendering.
+
+	This is a new technology for LCD-optimized rendering. It capitalizes
+	on the fact that each color channel grid is shifted by a third of a
+	pixel.  Therefore it is logical to render 3 separate monochrome
+	bitmaps shifting the outline by 1/3 pixel, and then combine them.
+	Importantly, the resulting output does not require additional LCD
+	filtering.
+
+	* src/smooth/ftsmooth.c (ft_smooth_render_generic)
+	[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
+	rendering.
+
+	* include/freetype/ftlcdfil.h, include/freetype/freetype.h,
+	include/freetype/config/ftoption.h, devel/ftoption.h: Updated
+	documentation.
+
+2017-08-08  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Clean up.
+
+2017-08-08  Alexei Podtelezhnikov  <apodtele@gmail.com>
+
+	* src/sfnt/ttpost.c (format): Use otspec-compliant versions.
+
+2017-08-05  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] Integer overflow.
+

+
+	* src/truetype/ttinterp.c (Ins_ALIGNRP): Use NEG_LONG.
+
+2017-08-05  Werner Lemberg  <wl@gnu.org>
+
+	[base, truetype] New function `FT_Get_Var_Axis_Flags'.
+
+	The reserved `flags' field got a value in OpenType version 1.8.2;
+	unfortunately, the public `FT_Var_Axis' structure misses the
+	corresponding element.  Since we can't add a new field, we add an
+	access function.
+
+	* src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.
+
+	* include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.
+	Updated.
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory
+	of `mmvar' to hold axis flags.
+	Fill the axis flags array.
+
+	* docs/CHANGES: Updated.
+
+2017-08-03  Nikolaus Waxweiler  <madigens@gmail.com>
+
+	[truetype] Fix metrics of B/W hinting in v40 mode.
+
+	Phantom points are now saved outside v40 backwards compatibility
+	mode.  This fixes the jumping glyphs when switching between v35 and
+	v40 monochrome mode.
+
+	* src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.
+
+2017-08-03  Nikolaus Waxweiler  <madigens@gmail.com>
+
+	[truetype] Do not set any ClearType flags in v40 monochrome mode.
+
+	This fixes weird behavior of instructions that resulted in rendering
+	differences between v35 and v40 in monochrome mode, e.g., in
+	`timesbi.ttf'.
+
+	* src/truetype/ttinterp.c (Ins_GETINFO)
+	[TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check
+	`subpixel_hinting_lean'.
+
+2017-08-01  Werner Lemberg  <wl@gnu.org>
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix thinko.
+
+2017-08-01  Behdad Esfahbod  <behdad@behdad.org>
+
+	[truetype] Fix loading of named instances.
+
+	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Preserve file position
+	while loading the `avar' table.
+
+2017-08-01  Werner Lemberg  <wl@gnu.org>
+
+	[sfnt, truetype] Minor adjustments for OpenType 1.8.2.
+
+	* src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now
+	(tighter) limits.
+
+	* src/truetype/ttgload.c (load_truetype_glyph): The new OpenType
+	version explicitly allows all negative values for the number of
+	contours if we have a composite glyph (this is for better backwards
+	compatibility I guess), but it still recommends value -1.

+
+	Handle some integer overflow run-time errors (#46149, #48979).
+
+	This commit (mainly for 32bit CPUs) is the first of a series of
+	similar commits to handle known integer overflows.  Basically, all
+	of them are harmless, since they affect rendering of glyphs only,
+	not posing security threats.  It is expected that fuzzying will show
+	up more overflows, to be fixed in due course.
+
+	The idea is to mark places where overflows can occur, using macros
+	that simply cast to unsigned integers, because overflow arithmetic
+	is well defined in this case.  Doing so suppresses run-time errors
+	of sanitizers without adding computational overhead.

+
+	[cff] s/cf2_floatToFixed/cf2_doubleToFixed/.

+	warning because the macro itself uses `double' literals).

+	[smooth] Implement minimal dynamic padding for LCD filtering.
+
+	Extra bitmap padding for LCD filtering depends on the filter.  The

+	needs only 1 extra subpixel.  This space could be already available
+	due to rounding.  In order to optimize the padding, we now expand

+
+	Add new `slight' auto-hinting mode.
+
+	This mode uses fractional advance widths and doesn't scale glyphs
+	horizontally, only applying vertical scaling and hinting.
+
+	At the same time, the behaviour of the `light' auto-hinter gets
+	restored for backward compatibility: Both vertical and horizontal
+	scaling is again based on rounded metrics values (this was changed
+	in a commit from 2017-03-30 as a side effect).  To be more precise,
+	the behaviour is restored for TrueType fonts only; for other font
+	formats like Type 1, this is a new feature of the `light' hinting
+	mode.
+
+	* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
+	(FT_RENDER_MODE_SLIGHT): New render mode.

+
+	[autofit] Prevent overlapping blue zones.
+
+	Problem reported as
+
+	  https://github.com/google/fonts/issues/632
+
+	The font in question (Nunito) has values 705 and 713 for the
+	reference and overshoot values, respectively, of the first blue
+	zone.  Blue zone 2, however, has value 710 for both the reference
+	and overshoot.  At 12ppem, reference and overshoot of blue zone 0
+	becomes 8px, while blue zone 2 becomes 9px.
+
+	A peculiarity of this font is that the tops of isolated vertical
+	stems like `N' have a slight overshoot also.  The auto-hinter tries
+	to find the nearest blue zone using the *original* coordinates.  For
+	vertical stems, this is value 713.  For normal horizontal tops like
+	in character `E', this is value 710.  Since value 713 is mapped to
+	8px but value 710 to 9px, `N' and similar characters are one pixel
+	higher than `E', which looks very bad.
+
+	This commit sanitizes blue zones to avoid such a behaviour.
+
+	* src/autofit/aflatin.c (af_latin_sort_blue): New function.
+	(af_latin_metrics_init_blues): Sort blue values and remove overlaps.

+
+	[autofit] Use better blue zone characters for lowercase latin.
+
+	The number of lowercase characters for computing the top flat blue
+	zone value was too small (in most cases only `x' and `z').  If one
+	of the two characters has a large serif, say, it can happen that
+	FreeType must select between two different values, having a 50%
+	chance to use the wrong one.  As a result, rendering at larger PPEM
+	values could yield uneven lowercase glyph heights.

+	[pcf] Make long family names configurable.
+
+	The change from 2016-09-29 was too radical (except for people using

+

+
+	To be filled later on with something useful.

+
+2017-01-06  Werner Lemberg  <wl@gnu.org>
+
+	[truetype] More generalization of GX stuff.
+
+	We need this later on for MVAR also.
+

+CHANGES BETWEEN 2.9 and 2.9.1
+
+  I. IMPORTANT BUG FIXES
+
+    - Type  1  fonts  containing   flex  features  were  not  rendered
+      correctly (bug introduced in version 2.9).
+
+    - CVE-2018-6942: Older  FreeType versions  can crash  with certain
+      malformed variation fonts.
+
+        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942
+
+
+  II. MISCELLANEOUS
+
+    - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage.
+
+    - The base  extensions `ftlcdfil' and  `ftfntfmt' are now  part of
+      the  base  module  (and  thus no  longer  configurable  in  file
+      `modules.cfg').
+
+    - Emboldening of bitmaps didn't work correctly sometimes,  showing
+      various artifacts (bug introduced in version 2.8.1).
+
+    - Use  of  the `freetype-config'  script  to  get compilation  and
+      linking  options   is  deprecated   since  it   doesn't  support
+      cross-compiling, among other  deficiencies.  Instead, you should
+      use the `pkg-config' interface.
+
+      The `configure'  script no longer installs  `freetype-config' by
+      default.  For  backwards compatibility,  a new  configure option
+      `--enable-freetype-config'   is  provided   that  reverts   this
+      decision.
+
+    - The auto-hinter script ranges have  been updated for Unicode 11.
+      No support  for new scripts  have been added, however,  with the
+      exception of Georgian Mtavruli.
+
+    - Support for cmake has been improved.
+
+    - The next  release will  remove support for  Position Independent
+      Code  as  needed  by  systems that  prohibit  automatic  address
+      fixups, such  as BREW.  [Compilation with  modern compilers that
+      use flags like `-fPIC' or `-fPIE' is not affected.]
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8.1 and 2.9
+
+  I. IMPORTANT BUG FIXES
+
+    - Advance width values of variation fonts were often wrong.
+
+    - More fixes for variation font support; you should update to this
+      version if you want to support them.
+
+
+  II. IMPORTANT CHANGES
+
+    - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine
+      to  handle  Type  1  fonts  also,  thus  greatly  improving  the
+      rendering of  this format.   This is the  new default.   The old
+      engine   is  still   available   if   the  configuration   macro
+      `T1_CONFIG_OPTION_OLD_ENGINE'    gets    defined;   using    the
+      `hinting-engine' property  of the `type1' driver  module you can
+      then switch between the two engines.
+
+    - A new function,  `FT_Set_Named_Instance', can be used  to set or
+      change the current named instance.
+
+    - Starting  with   this  FreeType  version,   resetting  variation
+      coordinates  will   return  to  the  currently   selected  named
+      instance.  Previously, FreeType returned to the base font (i.e.,
+      no instance set).
+
+
+  III. MISCELLANEOUS
+
+    - The `face_flags' field of the `FT_Face' structure has a new bit,
+      `FT_FACE_FLAG_VARIATION', which  is set if a  variation font has
+      been      altered      with      `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - If  the  current  face  is  a  named  instance,  the  new  macro
+      `FT_IS_NAMED_INSTANCE' returns true.
+
+    - `FT_IS_VARIATION' is  a new macro  that returns true  whenever a
+      face object has  been altered by `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - Changing  the  design  coordinates  of  a  variation  font  with
+      `FT_Set_Var_Design_Coordinates'                               or
+      `FT_Set_Var_Blend_Coordinates'  does  not  influence  the  named
+      instance index value (only `FT_Set_Named_Instance' does that).
+
+    - Special PostScript  names for named instances  are only returned
+      if the  named instance is set  with `FT_Set_Named_Instance' (and
+      the font  has corresponding  entries in  its `fvar'  table).  If
+      `FT_IS_VARIATION'  returns  true,  the  algorithmically  derived
+      PostScript name is provided, not  looking up special entries for
+      named instances.
+
+    - A new function  `FT_Done_MM_Var' is provided to  free the memory
+      returned in a call to `FT_Get_MM_Var'.
+
+    - On  platforms  using  the   `configure'  script,  the  installed
+      `ftoption.h' file  now correctly reflects  configuration options
+      like `--with-harfbuzz'.
+
+    - Better  support to  build FreeType  as  a DLL  on Windows  using
+      Visual C.
+
+    - All data specific to driver modules is now collected in a single
+      file,      `FT_DRIVER_H'.      Consequently,      the     macros
+      `FT_AUTOHINTER_H',   `FT_CFF_DRIVER_H',  `FT_TRUETYPE_DRIVER_H',
+      and `FT_PCF_DRIVER_H' still work but are deprecated.
+
+    - Some fuzzer fixes to better reject malformed fonts.
+
+    - The `ftbench' demo program has a new test for opening a new face
+      and loading some glyphs.
+
+    - The `ftbench' demo program has a  new option `-j' to specify the
+      last glyph index to be used in the tests.
+
+    - The  `ftgrid' demo  program has  a new  option `-n'  to suppress
+      display of named instances of variation fonts.
+
+    - The `ttdebug' demo program can now  show a stack trace (key `K')
+      and switch  between hexadecimal and decimal  display of integers
+      (key `I').
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8 and 2.8.1
+
+  I. IMPORTANT BUG FIXES
+
+    - B/W  hinting   of  TrueType   fonts  didn't  work   properly  if
+      interpreter version 38 or 40 was selected.
+
+    - Some severe  problems within the handling  of TrueType Variation
+      Fonts were found and fixed.
+
+    - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
+      the case with less input coordinates than axes.
+
+
+  II. IMPORTANT CHANGES
+
+    - By  default,  FreeType  now offers  high  quality  LCD-optimized
+      output without  resorting to ClearType techniques  of resolution
+      tripling and  filtering.  In  this method, called  Harmony, each
+      color channel  is generated separately after  shifting the glyph
+      outline, capitalizing  on the fact  that the color grids  on LCD
+      panels  are shifted  by  a third  of a  pixel.   This output  is
+      indistinguishable from ClearType with a light 3-tap filter.
+
+
+  III. MISCELLANEOUS
+
+    - Using the  new function `FT_Get_Var_Axis_Flags',  an application
+      can access the `flags' field  of a variation axis (introduced in
+      OpenType version 1.8.2)
+
+    - More sanity checks.
+
+    - The  internal representation  of buffers  for LCD  rendering has
+      changed (to be more precise, the amount of padding gets computed
+      differently).  Applications  that use  the FreeType API  are not
+      affected.
+
+    - To  reset all  design axis  values of  a variation  font to  its
+      default values you can now say
+
+        error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
+
+      This  also works  with functions  `FT_Set_MM_Design_Coordinates'
+      and `FT_Set_MM_Blend_Coordinates'.
+
+    - FreeType  now synthesizes  a  missing Unicode  cmap for  (older)
+      TrueType fonts also if glyph names are available.
+
+    - FreeType  has  improved  handling   of  BDF  fonts  without  the
+      `POINT_SIZE', `RESOLUTION_X', or  `RESOLUTION_Y' properties; the
+      library now  uses the values of  the `SIZE' keyword if  they are
+      missing.   Previously,   `SIZE'  was  completely   ignored,  and
+      FreeType used heuristic values instead.
+
+    - Multiple calls to `FT_Bitmap_Convert' do work now as advertised.
+      Previously,  they failed with an assertion error if there was an
+      empty bitmap between non-empty ones.
+
+    - The warping option  has moved  from `light'  to `normal' hinting
+      where  it replaces  the original hinting algorithm.  The `light'
+      mode is now always void of any hinting in x-direction.
+
+    - 16bit  compiler  support is  now  officially  ended.  We  didn't
+      provide any maintenance  since many years,  and given that there
+      were no error  or problem reports either it seems  that it is no
+      longer needed.
+
+    - The `ftgrid'  demo program  can now toggle  the display  of grid
+      lines with the `G' key.
+
+    - The `ftgrid' demo  program can toggle a different  set of colors
+      (suitable to color-blind people) with the `C' key.
+
+    - The `ftgrid'  demo program  now supports  the `-e'  command line
+      option to select a cmap.
+
+    - The `ftdump' demo program has a  new command line option `-t' to
+      output the SFNT table list.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7.1 and 2.8
+
+  I. IMPORTANT CHANGES
+
+    - Support for OpenType Variation Fonts is now complete.   The last
+      missing part was handling the `VVAR' and `MVAR' tables, which is
+      available with this release.
+
+    - A new  function `FT_Face_Properties' allows the  control of some
+      module  and   library  properties  per  font.    Currently,  the
+      following properties can be  handled: stem darkening, LCD filter
+      weights, and the random seed for the `random' CFF operator.
+
+    - The PCF change to show more `colourful' family names (introduced
+      in version 2.7.1) was too radical; it can now be configured with
+      PCF_CONFIG_OPTION_LONG_FAMILY_NAMES   at   compile   time.    If
+      activated, it can  be switched off at run time  with the new pcf
+      property  `no-long-family-names'.  If  the `FREETYPE_PROPERTIES'
+      environment variable is available, you can say
+
+        FREETYPE_PROPERTIES=pcf:no-long-family-names=1
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
+        Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
+        Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
+        Viet, Tifinagh, Unified Canadian Syllabics, Vai
+
+
+  II. IMPORTANT BUG FIXES
+
+    - `Light' auto-hinting  mode no  longer uses TrueType  metrics for
+      TrueType  fonts.   This bug  was  introduced  in version  2.4.6,
+      causing   horizontal  scaling   also.    Almost  all   GNU/Linux
+      distributions (with Fedora as  a notable exception) disabled the
+      corresponding patch for good reasons; chances are thus high that
+      you won't notice a difference.
+
+      If  optical backward  compatibility for  legacy applications  is
+      necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
+      configuration option.   However, it  is strongly  recommended to
+      avoid that, adjusting font sizes instead.
+
+    - Global size  metrics values  in the  `FT_Size_Metrics' structure
+      can be  different for TrueType  fonts.  Reason is that  in older
+      FreeType  versions  the  metrics  were  rounded  differently  to
+      integer pixels compared  to all other font  formats, yielding an
+      inconsistent behaviour if you used non-native hinting.  Starting
+      with this  version, global size  metrics for TrueType  fonts are
+      handled the same as other  font formats: `ascender' gets rounded
+      up,  `descender'  gets  rounded  down,  `height'  gets  normally
+      rounded, and `max_advance' gets normally rounded, too.
+
+      If you need more precise values of (global) ascender, descender,
+      height, or  `max_advance', please take the  corresponding values
+      from the `FT_Face' structure and scale them manually.
+
+    - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
+      now scales  the font linearly  again (bug introduced  in version
+      2.4.6).
+
+    - CVE-2017-8105,  CVE-2017-8287:  Older   FreeType  versions  have
+      out-of-bounds  writes  caused  by  heap-based  buffer  overflows
+      related to Type 1 fonts.
+
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287
+
+
+  III. MISCELLANEOUS
+
+    - A  new function  `FT_Set_Default_Properties' has  been added  to
+      parse    the    `FREETYPE_PROPERTIES'    environment    variable
+      (previously, it  was internal only).   `FT_Init_FreeType' always
+      call this  function, but  `FT_New_Library' does not  (similar to
+      `FT_Add_Default_Modules').
+
+    - To be in sync with OpenType version 1.7 and newer, macros
+
+        FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
+        FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
+        TT_NAME_ID_PREFERRED_FAMILY
+        TT_NAME_ID_PREFERRED_SUBFAMILY
+
+      are renamed to
+
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
+        TT_NAME_ID_TYPOGRAPHIC_FAMILY
+        TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY
+
+      The old macro names are deprecated (but still available).
+
+    - Support for SFNT `name' tables has been improved.
+
+      . Format  1 `name' tables  are now supported.  Use  new function
+        `FT_Get_Sfnt_LangTag' to access associated language tags.
+
+      . Language, encoding, and name IDs have been updated to OpenType
+        version 1.8.1.
+
+    - The new CFF  engine now handles the `random'  operator.  All CFF
+      opcodes are now supported.
+
+    - The CFF module  has a new property `random-seed'  to control the
+      pseudo-random number generation for the `random' operator.
+
+    - The `freetype-config' script is now a wrapper of `pkg-config' if
+      this program is available in the path.
+
+    - FT_LOAD_TARGET_LCD  is now  a  variant of  FT_LOAD_TARGET_LIGHT;
+      this should provide better rendering results.
+
+    - A mode to display  light auto-hinting with  subpixel positioning
+      has been added to `ftdiff'.

 <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>

-<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>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
-<p>It's important to use the right timing for changing this value: The creation of the glyph-to-script map that eventually uses the fallback script value gets triggered either by setting or reading a face-specific property like <a href="ft2-auto_hinter.html#glyph-to-script-map">glyph-to-script-map</a>, or by auto-hinting any glyph from that face. In particular, if you have already created an <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure but not loaded any glyph (using the auto-hinter), a change of the fallback script will affect this face.</p>

-<p>If FreeType gets compiled with FT_CONFIG_OPTION_USE_HARFBUZZ to make the HarfBuzz library access OpenType features for getting better glyph coverages, this property sets the (auto-fitter) script to be used for the default (OpenType) script data of a font's GSUB table. Features for the default script are intended for all scripts not explicitly handled in GSUB; an example is a &lsquo;dlig&rsquo; feature, containing the combination of the characters &lsquo;T&rsquo;, &lsquo;E&rsquo;, and &lsquo;L&rsquo; to form a &lsquo;TEL&rsquo; ligature.</p>
-<p>By default, this is <a href="ft2-auto_hinter.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_LATIN</a>. Using the &lsquo;default-script&rsquo; property, this default value can be changed.</p>

-<p>This property can be used with <a href="ft2-module_management.html#FT_Property_Get">FT_Property_Get</a> also.</p>
-<p>It's important to use the right timing for changing this value: The creation of the glyph-to-script map that eventually uses the default script value gets triggered either by setting or reading a face-specific property like <a href="ft2-auto_hinter.html#glyph-to-script-map">glyph-to-script-map</a>, or by auto-hinting any glyph from that face. In particular, if you have already created an <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure but not loaded any glyph (using the auto-hinter), a change of the default script will affect this face.</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>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>By default, FreeType enables a Unicode charmap and tags it with FT_ENCODING_UNICODE when it is either provided or can be generated from PostScript glyph name dictionaries in the font file. All other encodings are considered legacy and tagged only if explicitly defined in the font file. Otherwise, FT_ENCODING_NONE is used.</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.

 <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 LCD-optimized glyph bitmaps produced by FT_Render_Glyph can be filtered to reduce color-fringes by using <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> (not active in the default builds). It is up to the caller to either call <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> (if available) or do the filtering itself.</p>
+<p>Should you define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your &lsquo;ftoption.h&rsquo;, which enables patented ClearType-style rendering, the LCD-optimized glyph bitmaps should be filtered to reduce color fringes inherent to this technology. You can either set up LCD filtering with <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> or <a href="ft2-base_interface.html#FT_Face_Properties">FT_Face_Properties</a>, or do the filtering yourself. The default FreeType LCD rendering technology does not require filtering.</p>
 <p>The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like <a href="ft2-basic_types.html#FT_Pixel_Mode">FT_PIXEL_MODE_MONO</a>. You can use <a href="ft2-bitmap_handling.html#FT_Bitmap_Convert">FT_Bitmap_Convert</a> to transform them into 8-bit pixmaps.</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>

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>

-<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>

+<p>Many characters, especially for CJK scripts, 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 Variation Sequences (VS), consisting of a Unicode base character and a variation selector instead of further extending the already huge number of characters.</p>
+<p>Unicode maintains two different sets, namely &lsquo;Standardized Variation Sequences&rsquo; and registered &lsquo;Ideographic Variation Sequences&rsquo; (IVS), collected in the &lsquo;Ideographic Variation Database&rsquo; (IVD).</p>

+<p>To date (January 2017), the character with the most ideographic variations is U+9089, having 32 such IVS.</p>
+<p>Three Mongolian Variation Selectors have the values U+180B-U+180D; 256 generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation Selectors from the range U+E0100-U+E01EF only.</p>
+<p>A VS consists of the base character value followed by a single Variation Selector. For example, to get the first variation of U+9089, you have to write the character sequence &lsquo;U+9089 U+E0100&rsquo;.</p>
+<p>Adobe and MS decided to support both standardized and ideographic VS 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 variations supported by the font.</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>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>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 same holds for the Type&nbsp;1 and CID modules if compiled with T1_CONFIG_OPTION_OLD_ENGINE.</p>

+<p>All glyphs that pass through the auto-hinter will be emboldened unless this property is set to TRUE. The same is true for the CFF, Type&nbsp;1, and CID font modules if the &lsquo;Adobe&rsquo; engine is selected (which is the default).</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.</p>
+<p>By default, the Adobe engines for CFF, Type&nbsp;1, and CID fonts darken stems at smaller sizes, regardless of hinting, to enhance contrast. Setting this property, stem darkening gets switched off.</p>
+<p>For the auto-hinter, stem-darkening is experimental currently and thus switched off by default (this is, &lsquo;no-stem-darkening&rsquo; is set to TRUE by default). Total consistency with the CFF driver is not achieved right now 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>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>

At configuration time, these four control points can be set with the macro &lsquo;CFF_CONFIG_OPTION_DARKENING_PARAMETERS&rsquo;; the CFF, Type&nbsp;1, and CID drivers share these values. At runtime, the control points can be changed using the &lsquo;darkening-parameters&rsquo; property, as the following example demonstrates for the Type&nbsp;1 driver.</p>

+<p>By default, the seed value for the CFF &lsquo;random&rsquo; operator and the similar &lsquo;0 28 callothersubr pop&rsquo; command for the Type&nbsp;1 and CID drivers is set to a random value. However, mainly for debugging purposes, it is often necessary to use a known value as a seed so that the pseudo-random number sequences generated by &lsquo;random&rsquo; are repeatable.</p>
+<p>The &lsquo;random-seed&rsquo; property does that. Its argument is a signed 32bit integer; if the value is zero or negative, the seed given by the &lsquo;intitialRandomSeed&rsquo; private DICT operator in a CFF file gets used (or a default value if there is no such operator). If the value is positive, use it instead of &lsquo;initialRandomSeed&rsquo;, which is consequently ignored.</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>

+
+<p>Currently, three versions are available, two representing the bytecode interpreter with subpixel hinting support (old &lsquo;Infinality&rsquo; code and new stripped-down and higher performance &lsquo;minimal&rsquo; 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).</p>
+<p>If subpixel hinting is on, many TrueType bytecode instructions behave differently compared to B/W or grayscale rendering (except if &lsquo;native ClearType&rsquo; 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.</p>
+<p>Details on subpixel hinting and some of the necessary tweaks can be found in Greg Hitchcock's whitepaper at &lsquo;<a href="https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>&rsquo;. Note that FreeType currently doesn't really &lsquo;subpixel hint&rsquo; (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.</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-properties.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>

Features for the default script are intended for all scripts not explicitly handled in GSUB; an example is a &lsquo;dlig&rsquo; feature, containing the combination of the characters &lsquo;T&rsquo;, &lsquo;E&rsquo;, and &lsquo;L&rsquo; to form a &lsquo;TEL&rsquo; ligature.</p>
+<p>By default, this is <a href="ft2-properties.html#FT_AUTOHINTER_SCRIPT_XXX">FT_AUTOHINTER_SCRIPT_LATIN</a>. Using the &lsquo;default-script&rsquo; property, this default value can be changed.</p>

+<p>It's important to use the right timing for changing this value: The creation of the glyph-to-script map that eventually uses the default script value gets triggered either by setting or reading a face-specific property like <a href="ft2-properties.html#glyph-to-script-map">glyph-to-script-map</a>, or by auto-hinting any glyph from that face. In particular, if you have already created an <a href="ft2-base_interface.html#FT_Face">FT_Face</a> structure but not loaded any glyph (using the auto-hinter), a change of the default script will affect this face.</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;normal&rsquo; auto-hinting mode replacing it. 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 );

+
+<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;normal&rsquo; hinting mode.</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>A single property <a href="ft2-properties.html#interpreter-version">interpreter-version</a> is available, as documented in the &lsquo;<a href="ft2-properties.html#properties">Driver properties</a>&rsquo; section.</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>
@@ -122,137 +118,10 @@
 <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>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>

-</pre>
-<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>

+   *   FT_Face_Properties
+   *
+   * @description:
+   *   Set or override certain (library or module-wide) properties on a
+   *   face-by-face basis.  Useful for finer-grained control and avoiding
+   *   locks on shared structures (threads can modify their own faces as
+   *   they see fit).
+   *
+   *   Contrary to @FT_Property_Set, this function uses @FT_Parameter so
+   *   that you can pass multiple properties to the target face in one call.
+   *   Note that only a subset of the available properties can be
+   *   controlled.
+   *
+   *   * @FT_PARAM_TAG_STEM_DARKENING (stem darkening, corresponding to the
+   *     property `no-stem-darkening' provided by the `autofit', `cff',
+   *     `type1', and `t1cid' modules; see @no-stem-darkening).
+   *
+   *   * @FT_PARAM_TAG_LCD_FILTER_WEIGHTS (LCD filter weights, corresponding
+   *     to function @FT_Library_SetLcdFilterWeights).
+   *
+   *   * @FT_PARAM_TAG_RANDOM_SEED (seed value for the CFF, Type~1, and CID
+   *     `random' operator, corresponding to the `random-seed' property
+   *     provided by the `cff', `type1', and `t1cid' modules; see
+   *     @random-seed).
+   *
+   *   Pass NULL as `data' in @FT_Parameter for a given tag to reset the
+   *   option and use the library or module default again.
+   *
+   * @input:
+   *   face ::
+   *     A handle to the source face object.
+   *
+   *   num_properties ::

+   *

-   * @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;

-   *
-   *     FT_Property_Get( library, "autofitter",
-   *                               "glyph-to-script-map", &prop );
-   *
-   *     // adjust `prop.map' as needed right here

-   *   warping
-   *
-   * @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;
-   *
-   *

-   *                               "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

-   * @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.

-   *   By default, the Adobe CFF engine darkens stems as follows (if the

-   *
-   *   {

-   *   }
-   *
-   *   and piecewise linear in-between.  At configuration time, these four
-   *   control points can be set with the macro
-   *   `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'.  At runtime, the control
-   *   points can be changed using the `darkening-parameters' property, as

-   *   {
-   *     FT_Library  library;
-   *     FT_Int      darken_params[8] = {  500, 300,   // x1, y1

-   *                                      2000,   0 }; // x4, y4

-   *   }
-   *
-   *   The x~values give the stem width, and the y~values the darkening
-   *   amount.  The unit is 1000th of pixels.  All coordinate values must be
-   *   positive; the x~values must be monotonically increasing; the
-   *   y~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).
-   *

+   * @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 CFF driver's module name is `cff'.
+   *
+   *   Available properties are @hinting-engine, @no-stem-darkening,
+   *   @darkening-parameters, and @random-seed, as documented in the
+   *   @properties section.
+   *
+   *
+   *   *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 subpixels 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 subpixels 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.

+   *   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'.
+   *
+   *   A single property @interpreter-version is available, as documented in
+   *   the @properties section.
+   *
+   *   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_ _Backward_ _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
+   *   https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+   *   This technique is not to be confused with ClearType compatible
+   *   widths.  ClearType backward 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 backward
+   *   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.

+   * @description:
+   *   All glyphs that pass through the auto-hinter will be emboldened
+   *   unless this property is set to TRUE.  The same is true for the CFF,
+   *   Type~1, and CID font modules if the `Adobe' engine is selected (which
+   *   is the default).
+   *
+   *   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.
+   *
+   *   By default, the Adobe engines for CFF, Type~1, and CID fonts darken
+   *   stems at smaller sizes, regardless of hinting, to enhance contrast. 
+   *   Setting this property, stem darkening gets switched off.
+   *
+   *   For the auto-hinter, stem-darkening is experimental currently and
+   *   thus switched off by default (this is, `no-stem-darkening' is set to
+   *   TRUE by default).  Total consistency with the CFF driver is not
+   *   achieved right now 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.

+   *   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.

+   *   If subpixel hinting is on, many TrueType bytecode instructions behave

+   *   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.

+   *   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.

+   *

+   *
+   *   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 `normal' auto-hinting mode replacing it.
+   *   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;
+   *
+   *

+   *   }
+   *
+   * @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 `normal' hinting mode.

-   *   Read the `gasp' table from a TrueType or OpenType font file and
-   *   return the entry corresponding to a given character pixel size.
+   *   For a TrueType or OpenType font file, return the rasterizer behaviour
+   *   flags from the font's `gasp' table corresponding to a given
+   *   character pixel size.
    *
    * @input:
    *   face :: The source face handle.
+   *
    *   ppem :: The vertical character pixel size.
    *
    * @return:
    *   Bit flags (see @FT_GASP_XXX), or @FT_GASP_NO_TABLE if there is no
    *   `gasp' table in the face.
    *
+   * @note:
+   *   If you want to use the MM functionality of OpenType variation fonts
+   *   (i.e., using @FT_Set_Var_Design_Coordinates and friends), call this
+   *   function *after* setting an instance since the return values can
+   *   change.

-   * @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').

-   *
-   * @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.

-   *   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.

-<h3><a name="introduction">Introduction</a></h3>
-
-Jprof is a profiling tool.  I am writing it because I need to find out
-where mozilla is spending its time, and there do not seem to be any
-profilers for Linux that can handle threads and/or shared libraries.
-This code is based heavily on Kipp Hickman's leaky.
-
-<h3><a name="operation">Operation</a></h3>
-
-Jprof operates by installing a timer which periodically interrupts mozilla.
-When this timer goes off, the jprof code inside mozilla walks the function call
-stack to determine which code was executing and saves the results into the
-<code>jprof-log</code> and <code>jprof-map</code> files.  By collecting a large
-number of these call stacks, it is possible to deduce where mozilla is spending
-its time.
-
-<h3><a name="setup">Setup</a></h3>
-
-<p>Configure your mozilla with jprof support by adding
-<code>--enable-jprof</code> to your configure options (eg adding
-<code>ac_add_options --enable-jprof</code> to your <code>.mozconfig</code>) and
-making sure that you do <strong>not</strong> have the
-<code>--enable-strip</code> configure option set -- jprof needs symbols to
-operate.  On many architectures with GCC, you'll need to add
-<code>--enable-optimize="-O3 -fno-omit-frame-pointer"</code> or the
-equivalent to ensure frame pointer generation in the compiler you're using.</p>
-
-<p>Finally, build mozilla with your new configuration.  Now you can run jprof.</p>
-
-<h3><a name="usage">Usage</a></h3>
-<pre> jprof [-v] [-t] [-e exclude] [-i include] [-s stackdepth] [--last] [--all] [--start n [--end m]] [--output-dir dir] prog log [log2 ...]</pre>
-Options:
-<ul>
-  <li><b>-s depth</b> : Limit depth looked at from captured stack
-      frames</li>
-  <li><b>-v</b> : Output some information about the symbols, memory map, etc.</li>
-  <li><b>-t or --threads</b> : Group output according to thread.  May require external
-      LD_PRELOAD library to help force sampling of spawned threads; jprof
-       may capture the main thread only.  See <a
-       href="http://sam.zoy.org/writings/programming/gprof.html">gprof-helper</a>;
-       it may need adaption for jprof.</li>
-  <li><b>--only-thread id</b> : Only output data for thread 'id'</li>
-  <li><b>-e exclusion</b> : Allows excluding specific stack frames</li>
-  <li><b>-i inclusion</b> : Allows including specific stack frames</li>
-  <li><b>--last</b> : Only process data from the last 'section' of sampling
-      (starting at the last PROF)</li>
-  <li><b>--start N</b> : Start processing data at 'section' N </li>
-  <li><b>--end N</b> : Stop processing data at 'section' N </li>
-  <li><b>--output-dir dir</b> : Store generated .html files in the given directory </li>
-</ul>
-The behavior of jprof is determined by the value of the JPROF_FLAGS environment
-variable.  This environment variable can be composed of several substrings
-which have the following meanings:
-<ul>
-    <li> <b>JP_START</b> : Install the signal handler, and start sending the
-    timer signals.
-    
-    <li> <b>JP_DEFER</b> : Install the signal handler, but don't start sending
-    the timer signals.  The user must start the signals by sending the first
-    one (with <code>kill -PROF</code>, or with <code>kill -ALRM</code> if
-    JP_REALTIME is used, or with <code>kill -POLL</code> (also known as <code>kill -IO</code>) if JP_RTC_HZ is used).
-
-    <li> <b>JP_FIRST=x</b> : Wait x seconds before starting the timer
-
-    <li> <b>JP_PERIOD=y</b> : Set timer to interrupt every y seconds.  Only
-    values of y greater than or equal to 0.001 are supported.  Default is
-    0.050 (50ms).
-    
-    <li> <b>JP_REALTIME</b> : Do the profiling in intervals of real time rather
-    than intervals of time used by the mozilla process (and the kernel
-    when doing work for mozilla).  This could probably lead to weird
-    results (you'll see whatever runs when mozilla is waiting for events),
-    but is needed to see time spent in the X server.
-
-    <li> <b>JP_RTC_HZ=freq</b> : This option, only available on Linux if the
-    kernel is built with RTC support, makes jprof use the RTC timer instead of
-    using its own timer.  This option, like JP_REALTIME, uses intervals of real
-    time.  This option overrides JP_PERIOD.  <code>freq</code> is the frequency
-    at which the timer should fire, measured in Hz. It must be a power of 2.
-    The maximal frequency allowed by the kernel can be changed by writing to
-    <code>/proc/sys/dev/rtc/max-user-freq</code>; the maximum value it can be
-    set to is 8192.  Note that <code>/dev/rtc</code> will need to be readable
-    by the Firefox process; making that file world-readable is a simple way to
-    accomplish that.
-
-    <li> <b>JP_CIRCULAR=size</b> : This tells jprof to store samples in a
-    circular buffer of the given size, which then will be saved (appended)
-    to disk when SIGUSR1 is received or JProfStopProfiling is done.  If the
-    buffer overflows, the oldest entries will be evicted until there's
-    space for the new entry.<p>
-	 
-    SIGUSR2 will cause the circular buffer to be cleared.
-
-    <li> <b>JP_FILENAME=basefilename</b> : This is the filename used for
-    saving the log files to; the default is "jprof-log".  If Electrolysis
-    is used, each process after the first will have the process ID
-    added ("jprof-log-3212");
-
-</ul>
-
-<h4>Starting and stopping jprof from JavaScript</h4>
-<p>
-A build with jprof enabled adds four functions to the Window object:<p>
-<code>JProfStartProfiling()</code> and <code>JProfStopProfiling()</code>:  When used with JP_DEFER, these
-allow one to start and stop the timer just around whatever critical section is
-being profiled.</p><p>
-<code>JProfClearCircular()</code> and <code>JProfSaveCircular()</code>:
-These clear the circular buffer and save the buffer (without stopping), respectively.</p>
-
-<h4>Examples of JPROF_FLAGS usage</h4>
-<ul>
-
-  <li>To make the timer start firing 3 seconds after the program is started and
-  fire every 25 milliseconds of program time use:
-    <pre>
-        setenv JPROF_FLAGS "JP_START JP_FIRST=3 JP_PERIOD=0.025" </pre>
-
-  <li>To make the timer start on your signal and fire every 1 millisecond of
-  program time use:  
-    <pre>
-        setenv JPROF_FLAGS "JP_DEFER JP_PERIOD=0.001" </pre>
-
-  <li>To make the timer start on your signal and fire every 10 milliseconds of
-  wall-clock time use:  
-    <pre>
-        setenv JPROF_FLAGS "JP_DEFER JP_PERIOD=0.010 JP_REALTIME" </pre>
-
-  <li>To make the timer start on your signal and fire at 8192 Hz in wall-clock
-  time use:
-    <pre>
-        setenv JPROF_FLAGS "JP_DEFER JP_RTC_HZ=8192" </pre>
-  
-  <li>To make the timer start on JProfStartProfiling() and run continously
-      with a 1ms sample rate until told to stop, then save the last 1MB of
-      data:
-    <pre>
-        setenv JPROF_FLAGS "JP_DEFER JP_CIRCULAR=1048576 JP_PERIOD=0.001" </pre>
-
-</ul>
-
-<h4>Pausing profiles</h4>
-
-<P>jprof can be paused at any time by sending a SIGUSR1 to mozilla (<code>kill
--USR1</code>).  This will cause the timer signals to stop and jprof-map to be
-written, but it will not close jprof-log.  Combining SIGUSR1 with the JP_DEFER
-option allows profiling of one sequence of actions by starting the timer right
-before starting the actions and stopping the timer right afterward.
-
-<P>After a SIGUSR1, sending another timer signal (SIGPROF, SIGALRM, or SIGPOLL (aka SIGIO),
-depending on the mode) can be used to continue writing data to the same
-output.
-
-<P>SIGUSR2 will cause the circular buffer to be cleared, if it's in use.
-This is useful right before running a test when you're using a large,
-continuous circular buffer, or programmatically at the start of an action
-which might take too long (JProfClearCircular()).
-
-<h4>Looking at the results</h4>
-
-Now that we have <code>jprof-log</code> and <code>jprof-map</code> files, we
-can use the jprof executable is used to turn them into readable output.  To do
-this jprof needs the name of the mozilla binary and the log file.  It deduces
-the name of the map file:

-<h3><a name="interpretation">Interpretation</a></h3>
-
-
-The Jprof output is split into a flat portion and a hierarchical portion.
-There are links to each section at the top of the page.  It is typically
-easier to analyze the profile by starting with the flat output and following
-the links contained in the flat output up to the hierarchical output.
-
-<h4><a name="flat">Flat output</a></h3>
-
-The flat portion of the profile indicates which functions were executing
-when the timer was going off.  It is displayed as a list of functions names
-on the right and the number of times that function was interrupted on the
-left.  The list is sorted by decreasing interrupt count.  For example:
-
-<blockquote> <pre>
-Total hit count: 151603
-Count %Total  Function Name
-
-<a href="#23081">8806   5.8     __libc_poll</a>
-<a href="#40008">2254   1.5     __i686.get_pc_thunk.bx</a>
-<a href="#21390">2053   1.4     _int_malloc</a>
-<a href="#49013">1777   1.2     nsStyleContext::GetStyleData(nsStyleStructID)</a>
-<a href="#21380">1600   1.1     __libc_malloc</a>
-<a href="#603">1552   1.0     nsCOMPtr_base::~nsCOMPtr_base()</a>
-</pre> </blockquote>
-
-This shows that of the 151603 times the timer fired, 1777 (1.2% of the total) were inside nsStyleContext::GetStyleData() and 1552 (1.0% of the total) were in the nsCOMPtr_base destructor.
-
-<p>
-In general, the functions with the highest count are the functions which
-are taking the most time.
-
-<P>
-The function names are linked to the entry for that function in the
-hierarchical profile, which is described in the next section.
-
-<h4><a name="hier">Hierarchical output</a></h4>
-
-The hierarchical output is divided up into sections, with each section
-corresponding to one function.  A typical section looks something like
-this:
-
-<blockquote><pre>
- index  Count         Hits      Function Name
-                      <A href="#72871">     545 (46.4%) nsBlockFrame::ReflowInlineFrames(nsBlockReflowState&, nsLineList_iterator, int*)</A>
-                      <A href="#72873">     100 (8.5%)  nsBlockFrame::ReflowDirtyLines(nsBlockReflowState&)</A>
- 72870      4 (0.3%)  <a name=72870>     645 (54.9%)</a> <b>nsBlockFrame::DoReflowInlineFrames(nsBlockReflowState&, nsLineLayout&, nsLineList_iterator, nsFlowAreaRect&, int&, nsFloatManager::SavedState*, int*, LineReflowStatus*, int)</b>
-                      <A href="#72821">     545 (46.4%) nsBlockFrame::ReflowInlineFrame(nsBlockReflowState&, nsLineLayout&, nsLineList_iterator, nsIFrame*, LineReflowStatus*)</A>
-                      <A href="#72853">      83 (7.1%)  nsBlockFrame::PlaceLine(nsBlockReflowState&, nsLineLayout&, nsLineList_iterator, nsFloatManager::SavedState*, nsRect&, int&, int*)</A>
-                      <A href="#74150">       9 (0.8%)  nsLineLayout::BeginLineReflow(int, int, int, int, int, int)</A>

-                      <A href="#53077">       1 (0.1%)  PL_ArenaAllocate</A>
-</pre></blockquote>
-
-The information this block tells us is:
-
-<ul>
-<li>There were 4 profiler hits <em>in</em> <code>nsBlockFrame::DoReflowInlineFrames</code>
-<li>There were 645 profiler hits <em>in or under</em> <code>nsBlockFrame::DoReflowInlineFrames</code>.  Of these:
-<ul>
-  <li>545 were in or under <code>nsBlockFrame::ReflowInlineFrame</code>
-  <li>83 were in or under <code>nsBlockFrame::PlaceLine</code>
-  <li>9 were in or under <code>nsLineLayout::BeginLineReflow</code>
-  <li>1 was in or under <code>nsTextFrame::GetType</code>
-  <li>1 was in or under <code>nsLineLayout::RelativePositionFrames</code>
-  <li>1 was in or under <code>__i686.get_pc_thunk.bx</code>
-  <li>1 was in or under <code>PL_ArenaAllocate</code>
-</ul>
-<li>Of these 645 calls into <code>nsBlockFrame::DoReflowInlineFrames</code>:
-<ul>
-  <li>545 came from <code>nsBlockFrame::ReflowInlineFrames</code>
-  <li>100 came from <code>nsBlockFrame::ReflowDirtyLines</code>
-</ul>
-</ul>
-
-
-The rest of this section explains how to read this information off from the jprof output.
-
-<p>This block corresponds to the function <code>nsBlockFrame::DoReflowInlineFrames</code>, which is
-therefore bolded and not a link.  The name of this function is preceded by
-five numbers which have the following meaning.  The number on the left (72870)
-is the index number, and is not important.  The next number (4) and the
-percentage following (0.3%) are the number
-of times this function was interrupted by the timer and the percentage of
-the total hits that is.  The last number pair ("645 (54.9%)")
-are the number of times this function was in the call stack when the timer went
-off.  That is, the timer went off while we were in code that was ultimately
-called from <code>nsBlockFrame::DoReflowInlineFrames</code>.
-<p>For our example we can see that our function was in the call stack for
-645 interrupt ticks, but we were only the function that was running when
-the interrupt arrived 4 times.
-<P>
-The functions listed above the line for <code>nsBlockFrame::DoReflowInlineFrames</code> are its
-callers.  The numbers to the left of these function names are the numbers of
-times these functions were in the call stack as callers of
-<code>nsBlockFrame::DoReflowInlineFrames</code>.  In our example, we were called 545 times by
-<code>nsBlockFrame::ReflowInlineFrames</code> and 100 times by
-<code>nsBlockFrame::ReflowDirtyLines</code>.
-<P>
-The functions listed below the line for <code>nsBlockFrame::DoReflowInlineFrames</code> are its
-callees.  The numbers to the left of the function names are the numbers of
-times these functions were in the callstack as callees of
-<code>nsBlockFrame::DoReflowInlineFrames</code> and the corresponding percentages. In our example, of the 645 profiler hits under <code>nsBlockFrame::DoReflowInlineFrames</code> 545 were under <code>nsBlockFrame::ReflowInlineFrame</code>, 83 were under <code>nsBlockFrame::PlaceLine</code>, and so forth.<p>
-
-<b>NOTE:</b> If there are loops of execution or recursion, the numbers will
-not add up and percentages can exceed 100%.  If a function directly calls
-itself "(self)" will be appended to the line, but indirect recursion will
-not be marked.
-
-<h3>Bugs</h3>
-The current build of Jprof has only been tested under Ubuntu 8.04 LTS, but
-should work under any fairly modern linux distribution using GCC/GLIBC.
-Please update this document with any known compatibilities/incompatibilities.
-<p>
-If you get an error:<p><code>Inconsistency detected by ld.so: dl-open.c: 260: dl_open_worker: Assertion `_dl_debug_initialize (0, args->nsid)->r_state == RT_CONSISTENT' failed!
-</code><p>that means you've hit a timing hole in the version of glibc you're
-running.  See <a
-href="http://sources.redhat.com/bugzilla/show_bug.cgi?id=4578">Redhat bug 4578</a>.

-# This program splits up a jprof profile into multiple files based on a
-# list of functions in a text file.  First, a complete profile is
-# generated.  Then, for each line in the text file, a profile is
-# generated containing only stacks that go through that line, and also
-# excluding all stacks in earlier lines in the text file.  This means
-# that the text file, from start to end, is splitting out pieces of the
-# profile in their own file.  Finally, a final profile containing the
-# remainder is produced.
-
-# The program takes four arguments:
-#   (1) The path to jprof.
-#   (2) The path to the text file describing the splits.  The output
-#       will be placed in the same directory as this file.
-#   (3) The program that was profiled.
-#   (4) The jprof-log file generated by the profile, to be split up.
-# (Really, all arguments from (3) and later are passed through to
-# jprof, so additional arguments could be provided if you want to pass
-# additional arguments to jprof.)
-
-# In slightly more detail:
-#
-# This script uses jprof's includes (-i) and excludes (-e) options to
-# split profiles into segments.  It takes as input a single text file,
-# and from that text file creates a series of jprof profiles in the
-# directory the text file is in.
-#
-# The input file format looks like the following:
-#
-#   poll g_main_poll
-#   GetRuleCascade CSSRuleProcessor::GetRuleCascade(nsPresContext *, nsIAtom *)
-#   RuleProcessorData RuleProcessorData::RuleProcessorData(nsPresContext *, nsIContent *, nsRuleWalker *, nsCompatibility *)
-#
-# From this input file, the script will construct a profile called
-# jprof-0.html that contains the whole profile, a profile called
-# jprof-1-poll.html that includes only stacks with g_main_poll, a
-# profile called jprof-2-GetRuleCascade.html that includes only stacks
-# that have GetRuleCascade and do not have g_main_poll, a profile called
-# jprof-3-RuleProcessorData.html that includes only stacks that have the
-# RuleProcessorData constructor and do not have GetRuleCascade or
-# g_main_poll, and a profile called jprof-4.html that includes only
-# stacks that do not have any of the three functions in them.
-#
-# This means that all of the segments of the profile, except
-# jprof-0.html, are mutually exclusive.  Thus clever ordering of the
-# functions in the input file can lead to a logical splitting of the
-# profile into segments.

- * The memory profiler samples allocation events. An allocation event
- * includes a type (what and at where is going to be allocated), a
- * size, a timestamp and the corresponding stack trace. Free events
- * are also tracked. For managed languages, namely languages relying
- * on garbage collection, a free event is generated when an object is
- * reclaimed by the garbage collector.  These sampled events can be
- * used to approximate the full history of allocations afterwards.
- * That means we can get various memory profiles of a program in
- * different perspectives by post-processing the history in different
- * ways. The profiler is designed at the very beginning to support not
- * only JavaScript but also native codes. Naturally, not only
- * JavaScript objects but also native allocations are tracked.
- *
- * The result returned is the sampled allocation event traces in a
- * compact format. The events is sorted according to the timestamp
- * when the event happened. Each event has a trace index pointing to
- * the traces table. Each trace entry has a name index pointing to the
- * names table and a parent index pointing to the parent trace in the
- * traces table. By following the trace index one could rebuild the
- * complete backtrace of an allocation event.

-// ThreadProfile JSON Format
-// -------------------------
-//
-// The profile contains much duplicate information. The output JSON of the
-// profile attempts to deduplicate strings, frames, and stack prefixes, to cut
-// down on size and to increase JSON streaming speed. Deduplicated values are
-// streamed as indices into their respective tables.
-//
-// Further, arrays of objects with the same set of properties (e.g., samples,
-// frames) are output as arrays according to a schema instead of an object
-// with property names. A property that is not present is represented in the
-// array as null or undefined.
-//
-// The format of the thread profile JSON is shown by the following example
-// with 1 sample and 1 marker:
-//

-// LUL: A Lightweight Unwind Library.
-// This file provides the end-user (external) interface for LUL.
-
-// Some comments about naming in the implementation.  These are safe
-// to ignore if you are merely using LUL, but are important if you
-// hack on its internals.
-//
-// Debuginfo readers in general have tended to use the word "address"
-// to mean several different things.  This sometimes makes them
-// difficult to understand and maintain.  LUL tries hard to avoid
-// using the word "address" and instead uses the following more
-// precise terms:
-//
-// * SVMA ("Stated Virtual Memory Address"): this is an address of a
-//   symbol (etc) as it is stated in the symbol table, or other
-//   metadata, of an object.  Such values are typically small and
-//   start from zero or thereabouts, unless the object has been
-//   prelinked.
-//
-// * AVMA ("Actual Virtual Memory Address"): this is the address of a
-//   symbol (etc) in a running process, that is, once the associated
-//   object has been mapped into a process.  Such values are typically
-//   much larger than SVMAs, since objects can get mapped arbitrarily
-//   far along the address space.
-//
-// * "Bias": the difference between AVMA and SVMA for a given symbol
-//   (specifically, AVMA - SVMA).  The bias is always an integral
-//   number of pages.  Once we know the bias for a given object's
-//   text section (for example), we can compute the AVMAs of all of
-//   its text symbols by adding the bias to their SVMAs.
-//
-// * "Image address": typically, to read debuginfo from an object we
-//   will temporarily mmap in the file so as to read symbol tables
-//   etc.  Addresses in this temporary mapping are called "Image
-//   addresses".  Note that the temporary mapping is entirely
-//   unrelated to the mappings of the file that the dynamic linker
-//   must perform merely in order to get the program to run.  Hence
-//   image addresses are unrelated to either SVMAs or AVMAs.

-//   mode, no unwinding may be performed.  It is however allowable to
-//   perform administrative tasks -- primarily, loading of unwind info
-//   -- in this mode.  In particular, it is safe for the library to

-//   sense that there is no risk of deadlock against unwinding threads
-//   that might -- because of where they have been sampled -- hold the
-//   system's malloc lock.
-//
-// * Unwind mode.  In this mode, calls to ::Unwind may be made, but
-//   nothing else.  ::Unwind guarantees not to make any dynamic memory
-//   requests, so as to guarantee that the calling thread won't
-//   deadlock in the case where it already holds the system's malloc lock.
-//
-// The library is created in Admin mode.  After debuginfo is loaded,
-// the caller must switch it into Unwind mode by calling
-// ::EnableUnwinding.  There is no way to switch it back to Admin mode
-// after that.  To safely switch back to Admin mode would require the
-// caller (or other external agent) to guarantee that there are no

-// To test the Breakpad symbol dumper and processor thoroughly, for
-// all combinations of host system and minidump processor
-// architecture, we need to be able to easily generate complex test
-// data like debugging information and minidump files.
-// 
-// For example, if we want our unit tests to provide full code
-// coverage for stack walking, it may be difficult to persuade the
-// compiler to generate every possible sort of stack walking
-// information that we want to support; there are probably DWARF CFI
-// opcodes that GCC never emits. Similarly, if we want to test our
-// error handling, we will need to generate damaged minidumps or
-// debugging information that (we hope) the client or compiler will
-// never produce on its own.
-//
-// google_breakpad::TestAssembler provides a predictable and
-// (relatively) simple way to generate complex formatted data streams
-// like minidumps and CFI. Furthermore, because TestAssembler is
-// portable, developers without access to (say) Visual Studio or a
-// SPARC assembler can still work on test data for those targets.

-// A Label represents a value not yet known that we need to store in a
-// section. As long as all the labels a section refers to are defined
-// by the time we retrieve its contents as bytes, we can use undefined
-// labels freely in that section's construction.
-//
-// A label can be in one of three states:
-// - undefined,
-// - defined as the sum of some other label and a constant, or
-// - a constant.
-// 
-// A label's value never changes, but it can accumulate constraints.
-// Adding labels and integers is permitted, and yields a label.
-// Subtracting a constant from a label is permitted, and also yields a
-// label. Subtracting two labels that have some relationship to each
-// other is permitted, and yields a constant.
-//
-// For example:
-//
-//   Label a;               // a's value is undefined
-//   Label b;               // b's value is undefined
-//   {
-//     Label c = a + 4;     // okay, even though a's value is unknown
-//     b = c + 4;           // also okay; b is now a+8
-//   }
-//   Label d = b - 2;       // okay; d == a+6, even though c is gone
-//   d.Value();             // error: d's value is not yet known
-//   d - a;                 // is 6, even though their values are not known
-//   a = 12;                // now b == 20, and d == 18
-//   d.Value();             // 18: no longer an error
-//   b.Value();             // 20
-//   d = 10;                // error: d is already defined.
-//
-// Label objects' lifetimes are unconstrained: notice that, in the
-// above example, even though a and b are only related through c, and
-// c goes out of scope, the assignment to a sets b's value as well. In
-// particular, it's not necessary to ensure that a Label lives beyond
