	* builds/unix/ftsystem.c (FT_Stream_Open): Temporal fix to prevent
	32bit unsigned long overflow by 64bit filesize on LP64 platform,
	proposed by Sean McBride:
	http://lists.gnu.org/archive/html/freetype-devel/2007-03/msg00032.html

2007-03-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproj: s/230/231/.
	* builds/win32/visualc/index.html: s/221/231/.

	* vms_make.com: Add `ftgasp'.

2007-01-30  David Turner  <david@freetype.org>

	Tag sources with VER-2-3-1 to prepare release.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.

	* docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
	s/2.3.0/2.3.1/.

	* builds/unix/configure.raw (version_info): Set to 9:12:3.


	* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
	(af_loader_load_g): Disable the warper (i.e., the light hinting
	improvements) to make a 2.3.1 bugfix release before introducing a
	new feature.  This should give us more time to tune and improve the
	warper for the next release.

	* docs/CHANGES: Update accordingly.

2007-01-25  David Turner  <david@freetype.org>

	For light auto-hinting, improve glyph advance widths and resurrect
	normal/full hinting to its normal quality.

	* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
	and `xmax_delta'.
	* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
	and `xmax_delta'.

	* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
	preprocessor conditional with if-clause, handling both light and
	normal mode.

2007-01-25  David Turner  <david@freetype.org>

	* src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.

	* src/cff/cffgload.c (cff_decoder_parse_charstrings)
	<cff_op_callsubr, cff_op_callgsubr>: Fix sanity check for empty
	functions.

	* docs/CHANGES: Document light auto-hinting improvement.

2007-01-25  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
	correctly in a sanity check.  Since this function is only used to
	load local and global functions, any charstring that called the last
	local/global function would fail otherwise.  This fixes Savannah bug
	#18867.

	* docs/CHANGES: Document it.

2007-01-23  David Turner  <david@freetype.org>

	* src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
	prevented compilation when disabling both the unpatented and the
	bytecode interpreter in the TrueType font driver.

	not necessarily a final version, but it seems to work well.

	* src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
	Disable code.
	(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
	* src/autofit/aftypes.h: Activate AF_USE_WARPER.

	* src/autofit/afwarp.c (AF_WarpScore): Tune table.

	(af_warper_compute): Better handling of border cases.
	* src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
	and `X2'.

	* ChangeLog.22: This new file.

2007-01-21  Werner Lemberg  <wl@gnu.org>

	* docs/CHANGES: Document SHZ fix.

2007-01-21  George Williams  <gww@silcom.com>

	* src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
	points.

2007-01-21  Werner Lemberg  <wl@gnu.org>

	* src/sfnt/ttmtx.c (tt_face_get_metrics)
	[!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.

	warnings.

2007-01-15  Detlef Würkner  <TetiSoft@apg.lahn.de>

	* builds/amiga/makefile, builds/amiga/makefile.os4,
	builds/amiga/smakefile: Add `ftgasp.c' and `ftlcdfil.c'.

	* builds/amiga/include/freetype/config/ftconfig.h: Synchronize.

2007-01-14  Detlef Würkner  <TetiSoft@apg.lahn.de>

	s/index/strike_index/.
	* src/base/ftobjs.c (FT_Match_Size): s/index/size_index/.

	* src/gxvalid/gxvmorx5.c
	(gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/.

	* src/truetype/ttinterp.c (Compute_Point_Displacement),
	src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly

	(cff_service_ps_info): Register cff_ps_get_font_info.

2007-01-13  Werner Lemberg  <wl@gnu.org>

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix compilation

	* src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
	crash with some Mac OS X .dfont files.  Submitted by Masatake
	Yamato.

	* autogen.sh: Small fix to get it working on Mac OS X properly:
	The issue is that GNU libtool is called `glibtool' on this platform,

	values.

2007-01-08  David Turner  <david@freetype.org>

	* docs/CHANGES: Updated.

	* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add
	a new API `FT_Get_Gasp' to return entries of the `gasp' table
	corresponding to a given character pixel size.

	* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
	`gasp' table, in order to avoid potential problems with later
	versions.

	Scan for `/sfnts' token.

2007-01-07  Werner Lemberg  <wl@gnu.org>

	* src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.

2007-01-06  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_index_init): Remove unused variable.
	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

2007-01-04  David Turner  <david@freetype.org>

	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
	correctly.  This fixes Savannah bug #17876.


	Do not allocate interpreter-specific tables in memory if we are not
	going to load glyphs with the bytecode interpreter anyway.

	* src/truetype/ttgload.c (tt_loader_init): Load execution context
	only if glyph is hinted.
	Updated.
	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
	and `cvs_ready'.

	files are not used.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
	`horz_metrics_offset' and `vert_metrics_ofset'.
	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
	Updated.


	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.


	Do not load the CFF index offsets into memory, since this wastes a
	*lot* of heap memory with large Asian CFF fonts.  There is no
	significant performance loss.

	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
	`data_size'.

	cff_charset_cid_to_gindex): New functions.
	(cff_new_index): Renamed to...
	(cff_index_init): This.  Update all callers.
	Updated -- some code has been moved to `cff_index_load_offsets'.
	(cff_done_index): Renamed to...
	(cff_index_done): This.  Update all callers.
	(cff_index_get_pointers, cff_index_access_element): Updated to use
	stream offsets.
	(cff_charset_compute_cids): Set `num_glyphs' field.
	(cff_encoding_load): Updated.

	* src/cff/cffgload.c (cff_slot_load): Updated.

2007-01-04  David Turner  <david@freetype.org>

	* docs/INSTALL.UNIX: Simplify some parts, add reference to
	autogen.sh and pointer to README.CVS.

	* README.CVS: Add common problem description and solution
	when running autogen.sh.

	* docs/INSTALL: Add reference to MacOS X.

	* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

	* docs/TODO: Remove obsolete items.

	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
	(TWorker): This.
	Remove `count_table' and `memory'.
	Make `grays' a pointer.
	(TRaster): New structure.
	(count_table): New static array.
	(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
	Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
	ft_black_set_mode, ft_black_render): Updated.
	(ft_black_init): Don't initialize `count_table'.
	(ft_black_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/smooth/ftgrays.c (TRaster): Replaced with...
	(TWorker): This.
	Remove `memory'.
	(TRaster): New structure.

	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
	gray_render_span, gray_raster_render): Updated.
	(gray_raster_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
	the optimization is no longer experimental.

	Remove a typo that results in no hinting and a memory leak with some
	large Asian CFF fonts.

	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
	which happens when FT_Done_Library is called with still opened
	CFF_Faces in it.  We need to close all faces before destroying the
	modules, or else some bad things (memory leaks) may happen.

2007-01-02  Werner Lemberg  <wl@gnu.org>

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c: Specialized for Mac OS X only.
	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
	* builds/unix/configure.raw: Ditto. When explicit switches for
	FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
	builds/mac/ftmac.c is used instead of default src/base/ftmac.c.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
	* builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
	instead of src/base/ftmac.c

	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
	* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
	that cannot be built at present.

2006-12-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftobjs.c: Improvement of resource fork handler for
	POSIX, cf.
	  http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
	format or .dfont, to simulate the face index number counted by ftmac.c.

2006-12-08  Werner Lemberg  <wl@gnu.org>

	* builds/toplevel.mk (dist): Extract version number from freetype.h.

2006-12-08  Vladimir Volovich  <vvv@vsu.ru>

	* src/tools/apinames (State): Remove final comma in structure -- xlc
	v5 under AIX 4.3 doesn't like this.

2006-12-07  David Turner  <david@freetype.org>

	* src/autofit/afloader.c (af_loader_load_g): Small adjustment
	to the spacing of auto-fitted glyphs.  This only impacts rare
	cases (e.g., Arial Bold at rather small character sizes).

2006-12-03  Werner Lemberg  <wl@gnu.org>

	* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.

2006-12-01  Werner Lemberg  <wl@gnu.org>

	Add stubs to link the `ftgrid' test program when debugging is
	disabled in the auto-hinter.

2006-11-23  David Turner  <david@freetype.org>

	* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,

	Fix Savannah bug #15553.

	* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
	program after a change from mono to grayscaling (and vice versa).
	Use correct constant for comparison to get `exec->grayscale'.

2006-11-18  Werner Lemberg  <wl@gnu.org>

	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
	test for a valid glyph index must be deferred to the font drivers.
	This patch fixes Savannah bug #18301.

	* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
	(cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
	src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
	(pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
	src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
	(FNT_Load_Glyph): Check validity of `glyph_index'.

2006-11-13  David Turner  <david@freetype.org>

	* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine.  The interpreter
	`enhancements' are still too buggy for general use.

	* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
	FT_FORCE_LEGACY_LCD_FILTER at compile time.  Define these macros
	when building the library to change the default LCD filter to be
	used.  This is only useful for experimentation.

	* include/freetype/ftlcdfil.h: Update documentation.

2006-11-10  David Turner  <david@freetype.org>

	* src/smooth/ftsmooth.c: API change for the LCD
	filter.  The FT_LcdFilter value is an enumeration describing which
	filter to apply, with new values FT_LCD_FILTER_LIGHT and
	FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
	algorithm which produces strong color fringes for everything
	except very-well hinted text).

	* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
	second parameter to an enum type.

	* src/base/ftlcdfil.c (USE_LEGACY): Define.
	(_ft_lcd_filter): Rename to...
	(_ft_lcd_filter_fir): This.

	Handle new filter modes.

	* include/internal/ftobjs.h: Include FT_LCD_FILTER_H.
	(FT_Bitmap_LcdFilterFunc): Change third argument to `FT_Library'.
	(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering
	callback and update other fields.

	* src/smooth/ftsmooth.c (ft_smooth_render_generic)
	[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
	Other minor improvements.

	* src/autofit/aflatin.c: Various tiny improvements that drastically
	improve the handling of serif fonts and of LCD/LCD_V hinting modes.
	(af_latin_hints_compute_edges): Fix typo.
	(af_latin_compute_stem_width): Take better care of diagonal stems.

2006-11-09  David Turner  <david@freetype.org>

	* src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
	typo which created a variable-used-before-initialized bug.

2006-11-07  Zhe Su  <james.su@gmail.com>

	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
	also.

2006-11-03  Werner Lemberg  <wl@gnu.org>

	* src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

2006-11-02  David Turner  <david@freetype.org>

	Add a few tweaks to better handle serif fonts.
	Add more debugging messages.

	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
	segments that are less than 1.5 pixels high.  This gets rid of

	(af_latin_align_linked_edge): Add logging message.
	(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
	Add logging messages.

	* src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
	_af_debug_disable_blue_hints, and _af_debug_hints variables.

	* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
	Update external declarations.
	(af_corner_orientation, af_corner_is_flat): Replaced by...

	* include/freetype/internal/ftcalc.h (ft_corner_orientation,
	ft_corner_is_flat): These declarations.

	* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
	Comment out.  Replaced by...

	* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
	These functions.  Update all callers.
	(FT_Add64) [!FT_LONG64]: Simplify.

	* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
	(af_direction_compute): Add a missing FT_ABS call.  This bug caused
	production of garbage by missing lots of segments.

	* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.

	* src/autofit/afloader.c (af_loader_init, af_loader_done)
	[AF_DEBUG]: Set _af_debug_hints.


	* src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H.

2006-10-24  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_encoding_load): Remove unused variable.

	* src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE
	as argument.

2006-10-23  Zhe Su  <zsu@novell.com>

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
	better deal with broken Asian fonts with strange glyphs, having
	self-intersections and other peculiarities.  The used algorithm is
	based on the nonzero winding rule.

2006-10-23  David Turner  <david@freetype.org>

	Speed up the CFF font loader.  With some large CFF fonts,
	FT_Open_Face is now more than three times faster.

	* src/cff/cffload.c (cff_get_offset): Removed.
	(cff_new_index): Inline functionality of `cff_get_offset'.
	(cff_charset_compute_cids, cff_charset_free_cids): New functions.

	Rewrite, adding argument to handle all points at once.
	Update all callers.
	(PSH_MAX_STRONG_INTERNAL): New macro.
	(psh_glyph_interpolate_normal_points): Rewrite for efficiency.

2006-10-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c (FT_New_Face_From_FOND): Initialize variable
	`error' with FT_Err_Ok.

2006-10-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* docs/INSTALL.CROSS: New document file for cross-building.

	* builds/unix/configure.raw: Preliminary cross-building support.
	Find native C compiler and pass it by CC_BUILD, and

	Also suffix for target executable is passed by EXEEXT.

	* builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
	build `apinames' which runs on building system.  They are set by
	CC_BUILD and EXEEXT_BUILD.

	development.

2006-10-03  Jens Claudius  <jens.claudius@yahoo.com>

	* include/freetype/config/ftstdlib.h: Cast away volatileness from
	argument to ft_setjmp.

2006-09-27  David Turner  <david@freetype.org>

	* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.


	Add a new API to support color filtering of subpixel glyph bitmaps.
	In a default build, the function `FT_Library_SetLcdFilter' returns
	`FT_Err_Unimplemented_Feature'; you need to #define
	FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
	real implementation.

	* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

	* include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
	typedef.
	(FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
	`lcd_filter_weights' and `lcd_filter'.

	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove arguments
	`hmul' and `vmul'.

	Handle subpixel rendering.
	Simplify function.
	(ft_smooth_render_lcd): Use `FT_RENDER_MODE_LCD'.
	(ft_smooth_render_lcd_v): Use `FT_RENDER_MODE_LCD_V'.

	* include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
	pointing to <freetype/ftlcdfil.h>.

	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
	vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

	* modules.cfg (BASE_EXTENSIONS): Add ftlcdfil.c.

2006-09-26  David Bustin

	* src/pfr/pfrobjs.c (pfr_face_get_kerning): Skip adjustment bytes
	correctly.  Reported as Savannah bug #17843.

	auto-fitter.

	* src/autofit/afmodule.c (_af_debug_disable_horz_hints,
	_af_debug_disable_vert_hints) [AF_DEBUG]: New global variables.

	* src/autofit/aftypes.h [AF_DEBUG]: Declare above variables.

	* include/freetype/config/ftoption.h, devel/ftoption.h
	(FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
	we want to compile LCD-optimized rendering code (à la ClearType) or
	not.  The macro *must* be disabled in default builds of the library
	for patent reasons.

	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
	LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
	isn't defined at compile time.  This only changes the content of the
	rendered glyph to match the one of normal gray-level rendering,
	hence clients should not need to be modified.

	* docs/CHANGES: Updated.

2006-09-18  Garrick Meeker  <garrick@digitalanarchy.com>

	* src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if
	LWFN fails and both are available.

2006-09-11  David Turner  <david@freetype.org>

	* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which
	report their English names through an Apple Roman
	(platform,encoding) pair, with language_id != English.

	If the font uses another name entry with language_id == English, it
	will be selected correctly, though.

	* src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
	selection for `mingli.ttf'.

2006-09-05  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
	values which have the upper two bytes set to 0xFF instead of 0x00
	(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
	`HAN NOM B.ttf').

	* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.

2006-09-05  David Turner  <david@freetype.org>

	Minor source cleanups and optimizations.

2006-06-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Public API of TrueTypeGX, OpenType, and classic kern table validator
	should return `FT_Err_Unimplemented_Feature' if validation service

	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
	of `face->num_glyphs' which missed the last glyph, due to
	the offset-by-1 computation, since the PFR format doesn't

2006-05-25  Werner Lemberg  <wl@gnu.org>

	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out

	debug info.

2006-05-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

2006-05-17  David Turner  <david@freetype.org>

	This is a major patch used to drastically improve the performance of
	loading glyphs.  This both speeds up loading the glyph vectors
	themselves and the auto-fitter module.

	We now use inline assembler code with GCC to implement `FT_MulFix',
	which is probably the most important function related to the
	engine's performance.

	The resulting speed-up is about 25%.


	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
	`cursor' and `limit'.

	* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
	`FT_ZERO'
	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
	(af_glyph_hints_reload: Rewrite recognition of weak points.

	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
	constant values out of the loops.

	* src/autofit/aftypes.h: Updated.

	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
	product to get orientation.

	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
	(FT_Stream_OpenGzip): Use it to handle small files directly in
	memory.

	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
	Improve performance.

	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
	`limit'.

	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
	exceedingly large values of number of contours.  Speed up by
	reducing the number of loops.
