2016-07-11  Werner Lemberg  <wl@gnu.org>

	Conditionally compile environment support.

	* include/freetype/internal/ftobjs.h, src/autofit/afmodule.c,
	src/base/ftobjs.c, src/cff/cffdrivr.c, src/truetype/ttdriver.c:
	Decorate with `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' where
	necessary.

2016-07-11  Werner Lemberg  <wl@gnu.org>

	Handle properties in `FREETYPE_PROPERTIES' environment variable.

	This commit covers the most important one.

	* src/autofit/afmodule.c (af_property_set): Handle `warping',
	`darkening-parameters', and `no-stem-darkening'.

	* src/cff/cffdrivr.c (cff_property_set): Handle
	`darkening-parameters', `hinting-engine', and `no-stem-darkening'.

	* src/truetype/ttdriver.c (tt_property_set): Handle
	`interpreter-version'.

2016-07-11  Werner Lemberg  <wl@gnu.org>

	Replace calls to `atol' with `strtol'.

	We later on need strtol's `endptr' feature.

	* include/freetype/config/ftstdlib.h (ft_atol): Replace with...
	(ft_strtol): ... this.

	* src/base/ftdbgmem.c (ft_mem_debug_init): Updated.

	(FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES): New macro.

	* include/freetype/config/ftstdlib.h (ft_getenv): New macro.

	* src/base/ftinit.c (ft_set_default_properties): New function to
	parse `FREETYPE_PROPERTIES' and calling `ft_property_string_set'.
	(FT_Init_FreeType): Updated.

2016-07-09  Werner Lemberg  <wl@gnu.org>

	Add function `ft_property_string_set'.

	This is a preparation for handling an `FREETYPE_PROPERTIES'
	environment variable to control (some) driver properties.

	No change in functionality.

	* src/base/ftobjs.c (ft_property_do): Add `value_is_string'
	parameter.
	(ft_property_string_set): New function.
	(FT_Property_Set, FT_Property_Get): Updated.

	* include/freetype/internal/ftobjs.h: Updated.

	* include/freetype/internal/services/svprop.h
	(FT_Properties_SetFunc): Add `value_is_string' parameter.

	Updated, emitting an error currently if `value_is_string' is set.

2016-07-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[mac] Fix ftexport.sym target in Jamfile.

	* Jamfile: Update the directories of the header files scanned for
	ftexport.sym.  They were incorrect since the migration of the
	header files, on 2015-06-22.  Either inexisting include/cache
	(removed on 2006-03-20) is not needed to be listed explicitly.
	Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

	[smooth] Sub-banding protocol revision.

	Rasterization sub-banding is utilized at large sizes while using a
	rather small fixed memory pool.  Indeed it is possible to make an
	educated guess how much memory is necessary at a given size for a
	given glyph.  It turns out that, for a large majority of European
	glyphs, you should store about 8 times more boundary pixels than
	their height.  Or, vice versa, if your memory pool can hold 800
	pixels the band height should be 100 and you should sub-band
	anything larger than that.  Should you still run out of memory,
	FreeType bisects the band but you have wasted some time.  This is
	what has been implemented in FreeType since the beginning.

	It was overlooked, however, that the top band could grow to twice
	the default band size leading to unnecessary memory overflows there.
	This commit fixes that.  Now the bands are distributed more evenly
	and cannot exceed the default size.

	Now the magic number 8 is really suitable for rather simple European
	scripts.  For complex Chinese logograms the magic number should be
	13 but that is subject for another day.

	* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
	protocol.

2016-07-07  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[mac] Fix Savannah bug #48417.

	Mac OS X linker throws errors when `-exported_symbol_list' input
	file includes non-existing symbols.  Reported by Ryan Schmidt.

	* builds/exports.mk: Exclude ftmac.h from the headers for apinames
	by default.  Include it when ftmac.c would be compiled.

2016-07-04  Werner Lemberg  <wl@gnu.org>

	[autofit] Handle single-point contours as segments.

	Doing so allows us to link them to edges – some fonts like
	`NotoSansGurmukhi-Regular' have such isolated points sitting exactly
	on other outlines.

	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Don't
	ignore one-point contours but handle them specially as one-point
	segments.

	af_cyrl_uniranges): Add new data.

2016-07-01  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Variable type revision (part 1).

	This patch restores original `TCoord' definition as `int' so that the
	rendering pool is used more efficiently on LP64 platforms (unix).

	* src/smooth/ftgrays.c (gray_TWorker, TCell, gray_TBand): Switch some
	fields to `TCoord'.
	(gray_find_cell, gray_render_scanline, gray_render_line, gray_hline,
	gray_sweep, gray_convert_glyph): Updated.

2016-06-28  Alexei Podtelezhnikov  <apodtele@gmail.com>

2016-06-27  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Minor clean-ups.

	* src/smooth/ftgrays.c (gray_convert_glyph): Do not use volatile
	qualifier.
	(gray_raster_render): Move span initializations from here.

2016-06-26  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[pcf] Fix handling of very large fonts (#47708).

	* src/pcf/pcfread.c (pcf_get_encodings): Make `encodingOffset' an
	unsigned short.
	Only reject `0xFFFF' as an invalid encoding offset.

2016-06-25  Werner Lemberg  <wl@gnu.org>

	[truetype] Really fix deallocation in case of error (#47726).

	* src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize
	`outline.points' also.

2016-06-23  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Consolidate memory management.

	* src/smooth/ftgrays.c (gray_init_cells): Remove function.
	(gray_TWorker): Remove fields that become local variables.
	(gray_raster_render): Move rendering buffer declaration from here.
	(gray_convert_glyph): ... to here and update accordingly.

2016-06-22  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Consolidate boundary checks.

	Removing the checks from `gray_hline' shaves 1% off rendering speed.

2016-06-18  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Remove `band_shoot' that never worked.

	* src/smooth/ftgrays.c (gray_TWorker): Remove `band_shoot'.
	(gray_convert_glyph): Updated.

2016-06-17  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[cmake] Avoid modifying `ftconfig.h' and `ftoption.h' files.

	* CMakeLists.txt: Each time cmake is run those files are
	modified and the whole FreeType library is recompiled.  With this
	change we change the files only if there are real modifications, so
	we can avoid recompilations.

2016-06-09  Werner Lemberg  <wl@gnu.org>

	[bdf] Check number of properties (#48166).

	* src/bdf/bdflib.c (_bdf_parse_start): Implement.

2016-06-08  Alexei Podtelezhnikov  <apodtele@gmail.com>

2016-06-07  Werner Lemberg  <wl@gnu.org>

	[autofit] Fix compilation with VS2016 (#48126).

	This compiler doesn't recognize the end-of-comment sequence `*/' if
	it immediately follows non-ASCII characters.

	* src/autofit/afscript.h: Ensure whitespace before `*/'.

2016-06-04  Werner Lemberg  <wl@gnu.org>

	Fix a test for named instances (#48122).

	This was missed while giving negative face indices an extended
	meaning.

	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Implement.

2016-05-31  Nikolaus Waxweiler  <madigens@gmail.com>

	[truetype] Let SHPIX move points in the twilight zone in v40.

	* src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in
	the twilight zone.  Otherwise, treat SHPIX the same as DELTAP.
	Unbreaks various fonts such as older versions of Rokkitt and DTL
	Argo T Light that would glitch severly after calling ALIGNRP after a
	blocked SHPIX.

2016-05-30  Werner Lemberg  <wl@gnu.org>

	[type42] Support `CharStrings' entry format as created by LilyPond.

	* src/type42/t42parse.c (t42_parse_charstrings): Handle entries
	having the format

	  (foo) cvn 12345 def

2016-05-28  Werner Lemberg  <wl@gnu.org>

	* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.

	Suggested by Alexei.  `UL' is only needed for 16bit compilers, but
	it seems noone is using this anymore (and we no longer test whether
	FreeType compiles in such an environment).  Otherwise, it is easy to
	add the postfix to the `AF_UNICODE_RANGE' macro.

2016-05-26  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] Shrink bisection stack.

	The convergence of Bézier flatteners is fast with the deviation
	from straight line being assymptotically cut 4-fold on each bisection.
	This justifies smaller bisection stack size.

	* src/smooth/ftgrays.c (gray_TWorker): Remove common `bez_stack'.
	(gray_render_conic): Create and use conic `bez_stack'. Move back the
	band analysis from...
	(gray_conic_to): ... here.
	(gray_render_cubic): Create and use cubic `bez_stack'. Move back the
	band analysis from...
	(gray_cubic_to): ... here.
	(gray_move_to): Updated.

2016-05-25  Werner Lemberg  <wl@gnu.org>

	[autofit] Fixes for Armenian and Gujarati ranges.

	* src/autofit/afranges.c (af_armn_uniranges): Corrected.
	(af_guru_nonbase_uniranges): Make U+0A3E a base character.

2016-05-24  Werner Lemberg  <wl@gnu.org>

	[autofit] Add support for Armenian script.

	* src/autofit/afblue.dat: Add blue zone data for Armenian.

	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

	* src/autofit/afscript.h: Add Armenian standard characters.

	* src/autofit/afranges.c: Add Armenian data.

	* src/autofit/afstyles.h: Add Armenian data.

2016-05-23  Werner Lemberg  <wl@gnu.org>

	* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.

	This was commented about 10 years ago – I think the reason then to
	disable libtool's `-export-symbols' option was to give some badly
	programmed applications access to internal FreeType functions.

	I believe that we should no longer take care of such programs; the
	number of symbols exported should be rather restricted as much as
	possible.

2016-05-22  Werner Lemberg  <wl@gnu.org>

	[autofit] Add blue-zone support for Gurmukhi script.

	This essentially moves the Gurmukhi script from the `Indic' hinter to
	the `Latin' hinter.

	* src/autofit/afblue.dat: Add blue zone data for Gurmukhi.

	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

	* src/autofit/afscript.h: Add Gurmukhi standard characters and move
	data out of AF_CONFIG_OPTION_INDIC block.

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

	* src/autofit/afstyles.h: Update Gurmukhi data; in particular, use
	AF_WRITING_SYSTEM_LATIN.

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

	Minor clang++ fixes.

	* src/base/ftobjs.c (FT_Add_Module), src/psaux/psobjs.c
	(ps_parser_load_field), src/type1/t1load.c (parse_subrs): Add
	initializer.

	* src/cache/ftccache.h (FTC_CACHE_TRYLOOP_END): Avoid implicit
	conversion from NULL to boolean.

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

	Work around a bug of the C 8.0.0.1 compiler on AIX 5.3 (#47955).

	* include/freetype/internal/ftmemory.h (cplusplus_typeof): Use
	braces for `extern "C++"'.

2016-05-17  Nikolaus Waxweiler  <madigens@gmail.com>

	[truetype] Make TT_LOADER_SET_PP support subpixel hinting [3/3].

	* src/truetype/ttgload.c (TT_LOADER_SET_PP): Replace macro with...
	(tt_loader_set_pp): ... this new function.
	Update all callers.

2016-05-17  Nikolaus Waxweiler  <madigens@gmail.com>

	[truetype] New implementation of v38 bytecode interpreter [2/3].

	This patch actually modifies the bytecode interpreter.

	See added comments in `ttinterp.h' for more information on this and
	the following commit in the series.

	* src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by...
	(NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY,
	SUBPIXEL_HINTING_MINIMAL): ...new macros.
	(Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backwards
	compatibility.
	Updated.
	(Ins_RS, Ins_FDEF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_MD):
	Updated.
	(Ins_INSTCTRL): Handle native ClearType mode flag.
	Updated.
	(Ins_FLIPPT, Ins_FLIPRGON, Ins_FLIPRGOFF): Handle backwards
	compatibility.
	(Move_Zp2_Point): Ditto.
	(Ins_SHP): Updated.
	(Ins_SHPIX): Handle backwards compatibility.
	Updated.
	(Ins_MSIRP, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Updated.
	(Ins_ALIGNRP): Updated.
	(Ins_IUP, Ins_DELTAP): Handle backwards compatibility.
	Updated.
	(Ins_GETINFO): Handle v38 flags.
	Updated.
	(TT_RunIns): Handle backwards compatibility mode.
	Updated.

2016-05-17  Nikolaus Waxweiler  <madigens@gmail.com>

	[truetype] New implementation of v38 bytecode interpreter [1/3].

	This patch prepares data structures and the like.

	See added comments in `ttinterp.h' for more information on this and
	the following commits in the series.

	* devel/ftoption.h, include/freetype/config/ftoption.h
	(TT_CONFIG_OPTION_SUBPIXEL_HINTING): Assign values to differentiate
	between subpixel versions.
	(TT_SUPPORT_SUBPIXEL_HINTING_INFINALITY,
	TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL): New macros.

	* include/freetype/ftttdrv.h (TT_INTERPRETER_VERSION_40): New macro.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Updated.

	* src/truetype/ttinterp.h (TT_ExecContextRec): Define new fields
	`subpixel_hinting_lean', `vertical_lcd_lean',
	`backwards_compatibility', `iupx_called', iupy_called', and
	`grayscale_cleartype' for new hinting mode.

	* src/truetype/ttdriver.c (tt_property_set): Handle v38 and v40
	interpreters conditionally.

	* src/truetype/ttgload.c (TT_Hint_Glyph): Save phantom points unless
	in v38 backwards compatibility mode.
	Updated.
	(compute_glyph_metrics): Add v38 backwards compatibility mode
	constraint for adjusting advance widths.
	Updated.
	(tt_loader_init): Handle new flags `subpixel_hinting_lean',
	`grayscale_cleartype', and `vertical_lcd_lean'.
	Updated.
	(tt_get_metrics, TT_Process_Simple_Glyph, TT_LOADER_SET_PP):
	Updated.

	* src/truetype/ttobjs.c (tt_driver_init): Conditionally set
	default interpreter version number.

	* src/truetype/ttsubpix.c, src/truetype/ttsubpix.h: Updated.

2016-05-17  Werner Lemberg  <wl@gnu.org>

	[cff] Fix matrix scaling (#47848).

	* include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro.

	* src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling
	value of all matrix coefficients to scale matrix.

	* src/cff/cffobjs.c (cff_face_init): Use `matrix->yx' member for
	matrix normalization if `matrix->yy' is zero.

2016-05-16  Werner Lemberg  <wl@gnu.org>

	[base] Reject invalid sfnt Mac resource (#47891).

	* src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Check validity
	of `CID ' and `TYPE1' table offset and length.

2016-05-16  Werner Lemberg  <wl@gnu.org>

	[cid] Fix scanning for `StartData' and `/sfnts' (#47892).

	* src/cid/cidparse.c (STARTDATA, STARTDATA_LEN, SFNTS, SFNTS_LEN):
	New macros.
	(cid_parser_new): Fix and document algorithm.

2016-05-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[truetype] Improve the recursive reference detector.

	The previous fix for #46372 misunderstood a composite glyph referring
	same component twice as a recursive reference.  See the discussion

	  http://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html

	Thanks to Khaled Hosny for finding this issue.

	* src/truetype/ttgload.c (ft_list_get_node_at): A function to get
	the i-th node from FT_List.
	(load_truetype_glyph): In the traversal scan of the reference tree
	in the composite glyph, we clear the nodes filled by previous
	sibling chain.

2016-05-07  Werner Lemberg  <wl@gnu.org>

	[cache] Allow value 0 for face ID.

	We never dereference `face_id', and some implementations might use a
	running number instead of a pointer.  Additionally, disallowing
	value zero was undocumented.

	* src/cache/ftccmap.c (FTC_CMapCache_Lookup), src/cache/ftcmanag.c
	(FTC_Manager_LookupFace, FTC_Manager_RemoveFaceID): Remove test for
	`face_id'.

2016-05-05  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[smooth] More efficient accounting of conic splits and draws.

	A single decrement counter of segments to draw, instead of an array,
	contains all the information necessary to decide when to split and
	when to draw a conic segment. The number of splits before each draw is
	equal to the number of trailing zeros in the counter.

	* src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.
	(gray_render_conic): Updated to use decrement counter of segments.

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

	[cff, truetype] Fix logic for `FT_Property_Set'.

	Otherwise some properties could be set to arbitrary values, which is
	harmless, but querying could give wrong positive results.

	* src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
	* src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
	Only allow defined values.

2016-04-25  Werner Lemberg  <wl@gnu.org>

	[autofit] Add blue-zone support for Gujarati script.

	This essentially moves the Gujarati script from the `Indic' hinter to
	the `Latin' hinter.

	* src/autofit/afblue.dat: Add blue zone data for Gujarati.

	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

	* src/autofit/afscript.h: Add Gujarati standard characters and move
	data out of AF_CONFIG_OPTION_INDIC block.

	* src/autofit/afranges.c: Move Gujarati data out of
	AF_CONFIG_OPTION_INDIC block.

	* src/autofit/afstyles.h: Update Gujarati data; in particular, use
	AF_WRITING_SYSTEM_LATIN.

2016-04-24  Werner Lemberg  <wl@gnu.org>

	Minor.

	* include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Protect macro
	argument with parentheses.

2016-04-24  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix deallocation in case of error (#47726).

	* src/truetype/ttgload.c (load_truetype_glyph): Initialize fields in
	`outline' that are going to be deallocated in case of error.

2016-04-23  Werner Lemberg  <wl@gnu.org>

	[autofit] Improve Georgian blue zone characters.

	Suggested by Akaki Razmadze <razmadzekoko@gmail.com>.

	* src/autofit/afblue.dat (AF_BLUE_STRING_GEORGIAN_MKHEDRULI_BOTTOM):
	Updated.

	* src/autofit/afblue.c: Regenerated.

2016-04-16  David Capello  <davidcapello@gmail.com>

	[cmake] Honor SKIP_INSTALL_* settings (as used in zlib).

	As FreeType depends on zlib, if we don't install zlib (e.g., because
	we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too
	(cmake triggers an error saying that FreeType cannot be installed
	because zlib target isn't in the export set).

	* CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS',
	`SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings.

2016-04-16  Behdad Esfahbod  <behdad@behdad.org>

	[truetype] Another fix for non-intermediate GX tuples.

	* src/truetype/ttgxvar.c (ft_var_apply_tuple): Add some missing
	cases.

2016-04-12  Alexei Podtelezhnikov  <apodtele@gmail.com>

	Remove forgotten macro.

	* include/freetype/internal/internal.h
	[FT_INTERNAL_POSTSCRIPT_GLOBALS_H]: Remove.

2016-04-09  Werner Lemberg  <wl@gnu.org>

	[autofit] Add support for Georgian scripts.

	Georgian is problematic, since `uppercase' forms of Mkhedruli
	(called Mtavruli) are not yet defined in Unicode, which means that
	proper blue zones can't be defined.  However, there is already a
	proposal submitted to Unicode; see

	  http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf

	Additionally, due to historical reasons, Unicode treats Khutsuri as
	the same script as Mkhedruli, and so does OpenType.  However, since
	the two scripts have completely different shapes it can happen that
	blue zones differ considerably.  The tag `geok' used here (derived
	from ISO 15924) to differentiate the two scripts is not an OpenType
	tag in use.  If we now have a font that contains both glyphs for
	Mkhedruli and Khutsuri, and it uses OpenType features for both also,
	HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,
	blue zones for `geok' are not used for glyphs involved in the
	OpenType features.

	An issue not yet resolved is which OpenType feature should be used
	to access Mtavruli glyph shapes; right now, FreeType doesn't set up
	support for them, but it is easy to add them later on as soon as
	more information is available.

	[autofit] Provide dummy blue zone for pseudo script `none'.

	Even if the dummy hinter is used as the handler for `none' (which
	doesn't use blue zones), it is more consistent than the old value
	(which was 0), pointing to Arabic...

	* src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'.
	* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

	`enum' isn't normally) this works cleanly.

2016-03-26  Werner Lemberg  <wl@gnu.org>

	[pfr] Robustify bitmap strike handling (#47514).

	We did a binary search for a charcode without ensuring that the
	searched data is ordered.  Validating the order is now done lazily,
	this is, the first access to a bitmap glyph triggers the order check
	in the corresponding bitmap strike.

	`PFR_BITMAP_VALID_CHARCODES' and `PFR_BITMAP_CHARCODES_VALIDATED'.

	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly
	handle segments where the last point of the first segment is
	identical to the first point in the second one.  This can happen for

2016-01-19  Werner Lemberg  <wl@gnu.org>

	[autofit] Fix handling of default script.

	Patch taken from ttfautohint, commit
	071ae2c00e0d67f9d19418f4fade1c23d27dc185.

	There were two bugs.

	  - We now use non-standard script tags like `khms' for special
	    purposes.  However, HarfBuzz maps such tags to `DFLT', and
	    without this commit the associated lookups were incorrectly
	    assigned to the non-standard tags.

	  - Let's assume we have a Bengali font, and the font's `DFLT'
	    script tag handles the necessary lookups for Bengali, too.
	    Without this commit, the `DFLT' lookups were assigned to
	    ttfautohint's default script (usually `latn') before the
	    standard lookups for Bengali were handled.

	    We now have the following order while searching for covered
	    glyph indices.

	      special features of scripts (e.g. `sups' for Cyrillic)
	      Unicode mappings of scripts
	      remaining features of scripts (especially important for Indic
	        scripts)
	      default features of default script

	* src/autofit/afshaper.c, src/autofit/afshaper.h
	(af_shaper_get_coverage): Add boolean parameter to indicate default
	script.
	Update all callers.

	* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
	Fix search order for coverages.

	[autofit] Introduce subscript top blue zones.

	This feature is mainly for Khmer: The idea is to avoid a clash
	between the top of subscript glyphs and the bottom of normal
	baseline glyphs.

	This only works for character clusters mapped to multiple glyphs.

	* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.

2015-12-06  Werner Lemberg  <wl@gnu.org>

	[autofit] Rewrite HarfBuzz interface to support character clusters.

	Scripts like Khmer have blue zones that can't be directly
	represented by Unicode characters.  Instead, it is necessary to let
	HarfBuzz convert character clusters into proper glyph representation
	forms, then deriving the blue zone information from the resulting
	glyphs.

	* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
	* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
	files, providing a new API to access HarfBuzz.

	The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
	and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
	string with function `af_shaper_get_cluster', and the resulting
	glyph data (indices, advance widths, vertical offsets) can be
	iteratively accessed with function `af_shaper_get_elem'.

	* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
	af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

	clusters.

	* src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
	(AF_ScriptClassRec): Replace `standard_char[123]' with
	`standard_charstring'.

	of the `SCRIPT' calls with a string parameter, holding the standard
	characters (in UTF-8 encoding) separated with spaces.

	* src/autofit/afglobal.c, src/autofit/afglobal.h,
	src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c
	(SCRIPT): Updated.

2015-12-05  Werner Lemberg  <wl@gnu.org>

	* src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces.

	Instead, reduce multiple spaces to a single one.  We need this later
	for supporting character clusters in `afblue.dat'.

2015-12-05  Werner Lemberg  <wl@gnu.org>

	[pcf] Quickly exit if font index < 0.

	Similar to other font formats, this commit makes the parser no
	longer check the whole PCF file but only the header and the TOC if
	we just want to get the number of available faces (and a proper
	recognition of the font format).

	* src/pcf/pcfdrivr.c (PCF_Face_Init): Updated.

	[smooth] Faster alternative line renderer.

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

	* src/smooth/ftgrays.c (gray_render_line): New implementation.

	[base] Fix a leak by broken sfnt-PS or resource fork (#46028).

	open_face_from_buffer() frees passed buffer if valid font
	is not found.  But if copying to the buffer is failed,
	the allocated buffer should be freed within the caller.

	[sfnt] Better checks for invalid cmaps (2/2) (#46019).

	While the current code in `FT_Get_Next_Char' correctly rejects
	out-of-bounds glyph indices, it can be extremely slow for malformed
	cmaps that use 32bit values.  This commit tries to improve that.

	* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
	tt_cmap12_char_map_binary, tt_cmap13_next,
	tt_cmap13_char_map_binary): Reject glyph indices larger than or

	[sfnt] Improve handling of invalid SFNT table entries (#45987).

	This patch fixes weaknesses in function `tt_face_load_font_dir'.

	- It incorrectly assumed that valid tables are always at the
	  beginning.  As a consequence, some valid tables after invalid
	  entries (which are ignored) were never seen.

	- Duplicate table entries (this is, having the same tag) were not
	  rejected.

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

	* src/sfnt/ttload.c (check_table_dir): Add argument to return number
	of valid tables.
	Add another tracing message.
	(tt_face_load_font_dir): Only allocate table array for valid
	entries as returned by `check_table_dir'.

	accordingly.

	[gzip] Fix access of small compressed files (#45937).

	* src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak.

	(ft_gzip_get_uncompressed_file): Correct byte order while reading
	unsigned long value.  Without this change, the whole optimization of
	accessing small files in `FT_Stream_OpenGzip' is never executed!  As
	a consequence, access to PCF files in general (which are normally
	small files) should be much improved now as originally intended.

2015-09-11  Werner Lemberg  <wl@gnu.org>

	[psaux] Fix potential buffer overflow (#45922).

	[autofit] Redesign code ranges (2/2).

	This commit adds two fallback scripts (`latb', `latp') and

2015-09-04  Werner Lemberg  <wl@gnu.org>

	[autofit] Redesign code ranges (1/2).

	This patch introduces auxiliary code ranges that identify no-base
	characters; they refer to glyphs of a script that should be hinted
	without alignments to blue zones (mostly diacritics).

	It also splits off ranges for fallback scripts that handle subscript
	and superscript characters not covered by OpenType features.  For
	example, this greatly helps improve the hinting of various phonetic
	alphabets, which contain a large amount characters that look like
	superscript glyphs.

	Finally, code ranges are updated to Unicode 8.0, and enclosed
	characters are removed in general since they normally look better if
	they stay unhinted.

	* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
	8.0.
	Split off superscript-like and subscript-like glyphs into...

	(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

	(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
	of the corresponding character ranges.

	For functions querying a face, bits 16-30 of the face index can hold

	[type42] Fix glyph access.

	This is a severe bug: We've missed one level of indirection, as
	described in the Type 42 specification.  As a result, ftview
	sometimes showed incorrect glyphs for given glyph names, and even
	displayed `error 0x0006' (invalid argument!) in case the number of
	glyph indices differed between the Type 42 font and the embedded
	TTF.

	Apparently, noone ever noticed it; this shows how much Type 42 fonts
	are in use...

	* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
	to embedded TTF's glyph index.

	of the return value and make it faster too.

	* src/base/ftcalc.c (ft_corner_orientation): On 32-bit systems, stay

	Update creation of `ftconfig.h'.
	Install generated `ftconfig.h'.

	* Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

2015-06-22  Werner Lemberg  <wl@gnu.org>

	Fix Savannah bug #45097.

	We no longer `pollute' the namespace of possible header file names;
	instead we move `ft2build.h' up by one level so that it gets
	installed in the default include directory (e.g.,
	/usr/local/include).  After this commit, only `ft2build.h' stays in
	the compiler's include path.

	Make Jam support work again.

	This is just very basic stuff and just a little bit tested on
	GNU/Linux only.  I won't delve into this since I'm not a Jam user.

2015-06-03  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix memory leak.

	Problem reported by Grissiom <chaos.proton@gmail.com>; in

	  http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html

	there is an example code to trigger the bug.

	* src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size'

	* src/truetype/ttinterp.c: Change all existing TRACE7 calls to
	TRACE6.
	(opcode_name): Add string lengths.
	(TT_RunIns): Implement display of code position and stack.

2015-05-31  Werner Lemberg  <wl@gnu.org>

	[truetype] In GX, make private point numbers work correctly.

	This is completely missing in Apple's documentation: If a `gvar'
	tuple uses private point numbers (this is, deltas are specified for
	some points only), the uncovered points must be interpolated for
	this tuple similar to the IUP bytecode instruction.  Examples that
	need this functionality are glyphs `Oslash' and `Q' in Skia.ttf.

	* src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate,
	tt_handle_deltas): New functions.
	(TT_Vary_Get_Glyph_Deltas): Renamed to...
	(TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the
	points and does no longer return an array of deltas.
	Add tracing information.
	Call `tt_handle_deltas' to interpolate missing deltas.
	Also fix a minor memory leak in case of error.

	* src/truetype/ttgxvar.h: Updated.

	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
	load_truetype_glyph): Updated.

2015-05-31  Werner Lemberg  <wl@gnu.org>

2015-05-31  Werner Lemberg  <wl@gnu.org>

	[truetype] Add tracing information to GX code.

	* src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar,
	ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend,
	TT_Set_Var_Design, tt_face_vary_cvt): Do it.

2015-05-28  Werner Lemberg  <wl@gnu.org>

	* src/tools/apinames.c (names_dump): Fix invalid reference.

	Problem reported by Guzman Mosqueda, Jose R
	<jose.r.guzman.mosqueda@intel.com>.

2015-05-24  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix commit from 2015-05-22.

	* src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code
	with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'.

	Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.

2015-05-23  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix return values of GETINFO bytecode instruction.

	* src/truetype/ttinterp.h (TT_ExecContextRec): New fields
	`vertical_lcd' and `gray_cleartype'.

	* src/truetype/ttgload.c (tt_loader_init): Initialize new fields.
	Change `symmetrical smoothing' to TRUE, since FreeType produces
	exactly this.

	* src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit
	values for symmetrical smoothing, namely 11/18.
	Handle bits for vertical LCD subpixels (8/15) and Gray ClearType
	(12/19).

2015-05-23  Werner Lemberg  <wl@gnu.org>

	[truetype] Minor.

	* src/truetype/ttinterp.h (TT_ExecContext):
	 s/subpixel/subpixel_hinting.

	* src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.

2015-05-22  Werner Lemberg  <wl@gnu.org>

	[truetype] Support selector index 3 of the INSTCTRL instruction.

	This flag activates `native ClearType hinting', disabling backwards
	compatibility mode as described in Greg Hitchcocks whitepaper.  In
	other words, it enables unrestricted functionality of all TrueType
	instructions in ClearType.

	* src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks'
	unconditionally.
	(tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of
	`GS.instruct_control' is active.

	* src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3.
	(Ins_GETINFO): Updated.

	* docs/CHANGES: Document it.

2015-05-20  Werner Lemberg  <wl@gnu.org>

	[truetype] Minor.

	* src/truetype/ttinterp.h (SetSuperRound): Fix type of `GridPeriod'
	argument.

2015-05-17  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix loading of composite glyphs.

	* src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the
	ARGS_ARE_XY_VALUES flag is not set, handle argument values as
	unsigned.  I trust `ttx' (which has exactly such code) that it does
	the right thing here...

	The reason that noone has ever noticed this bug is probably the fact
	that point-aligned subglyphs are rare, as are subglyphs with a
	number of points in the range [128;255], which is quite large (or
	even in the range [32768;65535], which is extremely unlikely).

2015-05-12  Chris Liddell  <chris.liddell@artifex.com>

	[cff] Make the `*curveto' operators more tolerant.

	* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
	`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
	pulling values off the stack until the stack is exhausted.
	Implicitly the stack must be a multiple (or for subtly different
	behaviour) a multiple plus a specific number of extra values deep.
	If that's not the case, enforce it (as the old code did).

2015-05-12  Chris Liddell  <chris.liddell@artifex.com>

	[cff] fix incremental interface with new cff code.

	* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
	interface to retrieve glyph data for a SEAC, it be left to the
	incremental interface callback to apply the encoding to raw
	character index (as it was in the previous code).

2015-04-29  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[autofit] Speed up IUP.

	* src/autofit/afhints.c (af_iup_interp): Separate trivial snapping to
	the same position from true interpolation, use `scale' to reduce
	divisions.

2015-04-28  Werner Lemberg  <wl@gnu.org>

	[cff] Use `name' table for PS name if we have a SFNT-CFF.

	This follows the OpenType 1.7 specification.  See

	  http://tug.org/pipermail/tex-live/2015-April/036634.html

	for a discussion.

	* src/cff/cffdrivr.c (cff_get_ps_name): Use the `sfnt' service if we
	have an SFNT.

2015-04-27  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[AF_CONFIG_OPTION_USE_WARPER]: Use `AF_HINTS_DO_WARP' to control use
	of warper.

	* src/autofit/afcjk.c (af_cjk_hints_init, af_cjk_hints_apply)
	[AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.

	* src/autofit/aflatin2.c (af_latin2_hints_apply)

	* src/base/fttrigon.c (FT_Angle_Diff): Use loops instead of remainder.

2015-02-23  Werner Lemberg  <wl@gnu.org>

	[cache] Replace `FT_PtrDist' with `FT_Offset'.

	* src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t')
	is a better choice for `hash' to hold a pointer than `FT_PtrDist'
	(a.k.a. `ptrdiff_t'), especially since the latter is signed,

	type `FT_UInt32' before the change to `FT_PtrDist'.]

2015-02-19  Werner Lemberg  <wl@gnu.org>

	[autofit] Use macros for (unsigned) flags, not enumerations.

	[truetype] Fix regression in the incremental glyph loader.

	* src/truetype/ttgload.c (load_truetype_glyph): For incremental
	fonts, the glyph index may be greater than the number of glyphs
	indicated, so guard the check with a preprocessor conditional.

2015-02-06  Werner Lemberg  <wl@gnu.org>

	[autofit] Fix potential memory leak.

	While this doesn't show up with FreeType, exactly the same code
	leaks with ttfautohint's modified auto-hinter code (which gets used
	in a slightly different way).

	It certainly doesn't harm since it is similar to already existing
	checks in the code for embedded arrays.

	* src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours'
	and `max_points' for all cases.

2015-01-31  Werner Lemberg  <wl@gnu.org>

2015-01-18  Chris Liddell  <chris.liddell@artifex.com>

	[raster] Fix Savannah bug #44022.

	Add fallback for glyphs with degenerate bounding boxes.

	If a glyph has only one very narrow feature, the bbox can end up
	with either the width or height of the bbox being 0, in which case
	no raster memory is allocated and no attempt is made to render the
	glyph.  This is less than ideal when the drop-out compensation in
	the rendering code would actually result in the glyph being
	rendered.

	This problem can be observed with the `I' glyph (gid 47) in the
	Autodesk RomanS TrueType font.

	* src/raster/ftrend1.c (ft_raster1_render): Add a fallback if either
	dimension is zero to explicitly round up/down (instead of simply
	round).

2015-01-17  Werner Lemberg  <wl@gnu.org>

	Add some tools to handle yearly copyright notice updates.

	We are now following the GNU guidelines: A new release automatically
	means that the copyright year of all affected files gets updated; it
	is no longer used to track years of modification changes.

	* src/tools/update-copyright-year: New Perl script.
	* src/tools/update-copyright: New shell script that calls
	`update-copyright-year' on all files.
	* src/tools/no-copyright: Exceptions that should not be handled by
	`update-copyright'

2015-01-14  Werner Lemberg  <wl@gnu.org>

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[autofit] Add embedded array of segments and edges.

	Avoids multiple mallocs per typical glyphs.

	With this and recent changes to avoid mallocs, the thread-safe
	stack-based loader is now as fast as the previous model that had one
	cached singleton.

	* src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):
	New macros.
	(AF_AxisHintsRec): Add two arrays for segments and edges.

	* src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate
	data if number of segments exceeds given threshold value.
	(af_axis_hints_new_edge):  Only allocate data if number of edges
	exceeds given threshold value.
	(af_glyph_hints_done): Updated.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[autofit] Add embedded arrays for points and contours.

	This avoids at least two malloc calls for typical glyphs.

	* src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED):
	New macros.
	(AF_GlyphHintsRec): Add two arrays for contours and points.

	* src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done):
	Updated.
	(af_glyph_hints_reload): Only allocate data if number of contours or
	points exceeds given threshold values.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[autofit] Allocate hints object on the stack.

	This avoids one malloc per load.

	* src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to
	`AF_GlyphHints'.
	Update prototype.

	* src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints'
	parameter instead of `FT_Memory'.
	(af_loader_done): Directly reset `load_hints'.
	(af_loader_load_g): Updated.

	* src/autofit/afmodule.c (af_autofitter_load_glyph): Use local
	`hints' object.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[autofit] Reuse slot glyph loader.

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

	* src/autofit/afloader.c (af_loader_init): Change return type to
	`void'.
	Don't call `FT_GlyphLoader_New'.
	(af_loader_reset): Don't call `FT_GlyphLoader_Rewind'.
	(af_loader_load_g): Update code to use `internal->loader', which
	doesn't need copying of data.

	* src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member.
	Update prototype.

	* src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[autofit] Remove (unused) support for composite glyphs.

	We never have to deal with composite glyphs in the autohinter, as
	those will be loaded into FORMAT_OUTLINE by the recursed
	`FT_Load_Glyph' function.

	In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply
	FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies
	FT_LOAD_NO_HINTING:

	  /* resolve load flags dependencies */

	  if ( load_flags & FT_LOAD_NO_RECURSE )
	    load_flags |= FT_LOAD_NO_SCALE         |
	                  FT_LOAD_IGNORE_TRANSFORM;

	  if ( load_flags & FT_LOAD_NO_SCALE )
	  {
	    load_flags |= FT_LOAD_NO_HINTING |
	                  FT_LOAD_NO_BITMAP;

	    load_flags &= ~FT_LOAD_RENDER;
	  }

	and as such the auto-hinter is never called.  Thus, the recursion in
	`af_loader_load_g' never actually happens.  So remove the depth
	counter as well.

	* src/autofit/afloader.c (af_loader_load_g): Remove `depth'
	parameter.
	<FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code.
	(af_loader_load_glyph): Updated.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[raster] Fix uninitialized memory access.

	Apparently `ras.cProfile' might be uninitialized.  This will be the
	case if `ras.top == ras.cProfile->offset', as can be seen in
	`End_Profile'.  The overshoot code introduced in a change `Fix B/W
	rasterization of subglyphs with different drop-out modes.' (from
	2009-06-18) violated this, accessing `ras.cProfile->flags'
	unconditionally just before calling `End_Profile' (which then
	detected that `cProfile' is uninitialized and didn't touch it).

	This was harmless, and was not detected by valgrind before because
	the objects were allocated on the `raster_pool', which was always
	initialized.  With recent change to allocate raster buffers on the
	stack, valgrind now reported this invalid access.

	* src/raster/ftraster.c (Convert_Glyph): Don't access an
	uninitialized `cProfile'.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[smooth] Fix uninitialized memory access.

	Looks like `ras.span_y' could always be used without initialization.
	This was never detected by valgrind before because the library-wide
	`raster_pool' was used for the worker object and `raster_pool' was
	originally zero'ed.  But subsequent reuses of it were using `span_y'
	uninitialized.  With the recent change to not use `render_pool' and
	allocate worker and buffer on the stack, valgrind now detects this
	uninitialized access.

	* src/smooth/ftgrays.c (gray_raster_render): Initialize
	`ras.span_y'.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[base] Don't initialize unused `driver->glyph_loader'.

	* src/base/ftobjs.c (Destroy_Driver): Don't call
	`FT_GlyphLoader_Done'.
	(FT_Add_Module): Don't call `FT_GlyphLoader_New'.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[base] Don't allocate `library->raster_pool' anymore.

	It's unused after the following commits:

	  [raster] Allocate render pool for mono rasterizer on the stack.
	  [raster] Remove 5-level gray AA mode from monochrome rasterizer.

	The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
	serve, which is, to adjust the pool size.  But the pool is now
	allocated on the stack on demand.

	* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[base] Do not reorder library->renderers upon use.

	Instead of keeping `library->renderers' in a MRU order, just leave
	it as-is.  The MRU machinery wasn't thread-safe.

	With this patch, rasterizing glyphs from different faces from
	different threads doesn't fail choosing rasterizer
	(FT_Err_Cannot_Render_Glyph).

	Easiest to see that crash was to add a `printf' (or otherwise let
	thread yield in FT_Throw with debugging enabled).

	* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
	(FT_Outline_Render): Don't call `FT_Set_Renderer'.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[raster] Allocate render pool for mono rasterizer on the stack.

	Instead of using the `render_pool' member of `FT_Library' that is
	provided down to the rasterizer, completely ignore that and allocate
	needed objects on the stack instead.

	With this patch, rasterizing glyphs from different faces from
	different threads doesn't crash in the monochrome rasterizer.

	* src/raster/ftraster.c (black_TRaster): Remove `buffer',
	`buffer_size', and `worker' members.

	(ft_black_render): Create `buffer' locally.
	(ft_black_reset): Updated.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[raster] Remove 5-level gray AA mode from monochrome rasterizer.

	It was off by default and couldn't be turned on at runtime.  And the
	smooth rasterizer superceded it over ten years ago.  No point in
	keeping.  Comments suggested that it was there for compatibility
	with FreeType 1.

	550 lines down.

	* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
	RASTER_GRAY_LINES): Remove macros and all associated code.

	(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
	(black_TRaster): Remove `grays' and `gray_width'.

	(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,
	ft_black_render): Updated.

	* src/raster/ftrend1.c (ft_raster1_render): Simplify code.
	(ft_raster5_renderer_class): Removed.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[smooth] Allocate render pool for smooth rasterizer on the stack.

	Instead of using the `render_pool' member of `FT_Library' that is
	provided down to the rasterizer, completely ignore that and allocate
	needed objects on the stack instead.

	With this patch, rasterizing glyphs from different faces from
	different threads doesn't crash in the smooth rasterizer.

	(gray_raster_reset): Updated.

2015-01-14  Behdad Esfahbod  <behdad@behdad.org>

	[truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.

	Previously the code had stipulation for using a per-TT_Size exec
	context if `size->debug' was true.  But there was no way that
	`size->debug' could *ever* be true.  As such, the code was always
	using the singleton `TT_ExecContext' that was stored in `TT_Driver'.
	This was, clearly, not threadsafe.

	With this patch, loading glyphs from different faces from different
	threads doesn't crash in the bytecode loader code.

	* src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member.
	(TT_DriverRec): Remove `context' member.

	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove
	`TT_ExecContext' code related to a global `TT_Driver' object.

	(tt_driver_done): Don't remove `TT_ExecContext' object here but ...
	(tt_size_done_bytecode): ... here.

	(tt_driver_init): Don't create `TT_ExecContext' object here but ...
	(tt_size_init_bytecode): ... here, only on demand.

	* src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug
	code.
	(TT_New_Context): Remove `TT_ExecContext' code related to a global

	[autofit] Allocate AF_Loader on the stack instead of AF_Module.

	Stop sharing a global `AF_Loader'.  Allocate one on the stack during
	glyph load.

	Right now this results in about 25% slowdown, to be fixed in a
	following commit.

	With this patch loading glyphs from different faces from different
	threads doesn't immediately crash in the autohinting loader code.

	Bugs:
