ChangeLog

2007-04-03  David Turner  <david@freetype.org>

	* src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,
	if one of the resolution is 0, treat it as if it was the same than
	the other value.

2007-04-02  David Turner  <david@freetype.org>

	Add special code to detect `extra-light' fonts and do not snap their
	stem widths too much to avoid bizarre hinting effects.

	* src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
	`extra_light' members.

	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize
	them.
	(af_latin_metrics_scale_dim): Set `extra_light'.
	(af_latin_compute_stem_width): Use `extra_light'.

2007-03-28  David Turner  <david@freetype.org>

	* src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix zero-ing of the
	padding.

2007-03-28  Werner Lemberg  <wl@gnu.org>

	* src/bdf/bdflib.c (setsbit, sbitset): Handle values >= 128
	gracefully.
	(_bdf_set_default_spacing): Increase `name' buffer size to 256 and
	issue an error for longer names.
	(_bdf_parse_glyphs): Limit allowed number of glyphs in font to the
	number of code points in Unicode.

	* builds/win32/visualc/index.html,
	builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproc, README: s/2.3.2/2.3.3/,
	s/232/233/.

	* docs/CHANGES: Mention ftdiff.

2007-03-26  David Turner  <david@freetype.org>

	* src/truetype/ttinterp.c [FIX_BYTECODE]: Remove it and
	corresponding code.
	(Ins_MD): Last regression fix.

	* src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
	computations in order to ignore single-point contours.  These are
	never rasterized and correspond in certain fonts to mark-attach
	points that are very far from the glyph's real outline, ruining the
	computation.

	* src/autofit/afloader.c (af_loader_load_g): In the case of
	monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0. 
	Otherwise code that uses them will most certainly ruin the fixed
	advance property.

	* docs/CHANGES, docs/VERSION.DLL, README, Jamfile (RefDoc): Update
	documentation and bump version number to 2.3.3.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 3.

	* builds/unix/configure.raw (version_info): Set to 9:14:3.

	* include/freetype/config/ftconfig.h: Ditto.

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

	* builds/unix/ftsystem.c (FT_Stream_Open): Temporary fix to prevent
	32bit unsigned long overflow by 64bit filesize on LP64 platform, as
	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/unix/ftconfig.in: Suppress SGI compiler's warning against
	setjmp, proposed by Sean McBride:
	http://lists.gnu.org/archive/html/freetype-devel/2007-03/msg00032.html

2007-03-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Dequote `OS_INLINE' in comment of
	conftest.c, to avoid unexpected shell evaluation.  Possibly it is a
	bug or undocumented behaviour of autoconf.

2007-03-18  David Turner   <david@freetype.org>

	* src/truetype/ttinterp.c (Ins_MDRP): Another bytecode regression
	fix; testing still needed.

	* src/truetype/ttinterp.c (Ins_MD): Another bytecode regression fix.

2007-03-17  David Turner   <david@freetype.org>

	some cases.  Reported by James Cloos <cloos@jhcloos.com>.


2007-03-05  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttobs.c (tt_size_init_bytecode): Clear the `x_ppem'
	and `y_ppem' fields of the `TT_Size.metrics' structure, not those of
	`TT_Size.root.metrics'.  Problem reported by Daniel Glöckner
	<daniel-gl@gmx.net>.

	* src/type1/t1afm.c (T1_Read_PFM): Read kerning values as 16-bit
	signed values, not unsigned ones.  Problem reported by Johannes
	Walther <joh_walt@yahoo.de>.

2007-02-21  David Turner  <david@freetype.org>

	* src/pshinter/pshalgo.c (psh_hint_align): Fix a bug in the hinting

	af_latin_hints_compute_edges): Slight optimization of the segment
	linker and better handling of serif segments to get rid of broken
	`9' in Arial at 9pt (96dpi).

	* Version 2.3.1 released.
	=========================


	Tag sources with `VER-2-3-1-FINAL'.

	* 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.

	* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.

	* 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.

	Disable code.
	(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.

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

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

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

	* src/truetype/ttinterp.c (Compute_Point_Displacement),

	* 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,

	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'.
	Add `tt_size_ready_bytecode' declaration.
	* src/truetype/ttobjs.c (tt_size_done_bytecode,
	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
	(tt_size_init): Move most code into `tt_size_init_bytecode'.
	(tt_size_done): Move most code into `tt_size_done_bytecode'.
	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.


	Don't extract the metrics table from the SFNT font file.  Instead,
	reparse it on each glyph load.  The runtime difference is not
	noticeable, and it can save a lot of heap memory when memory-mapped
	files are not used.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
	`horz_metrics_offset' and `vert_metrics_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_CharsetRec): Add field `num_glyphs'.

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

	* 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.

	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
	Remove a typo that results in no hinting and a memory leak with some
	large Asian CFF fonts.

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

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

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
	Remove compiler warning.

2007-01-02  David Turner  <david@freetype.org>

	* src/sfnt/sfobjs.c: Add documentation comment.

2006-12-31  Masatake YAMATO  <jet@gyve.org>

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New
	function.
	Check uniqueness of the gid pairs.
	(gxv_kern_subtable_fmt0_validate): Move some code to
	`gxv_kern_subtable_fmt0_pairs_validate'.

2006-12-22  David Turner  <david@freetype.org>

	* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
	warnings.

	* builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
	to avoid deprecation warnings with Visual C++ 8.

2006-12-16  Anders Kaseorg  <anders@kaseorg.com>

	* src/base/ftlcdfil.c (FT_Library_SetLcdFilter)
	[FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.

	* include/freetype/internal/services/svotval.h: Add `volatile' to
	sync with the modification by Jens Claudius on 2006-08-22; cf.
	  http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5

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

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

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

	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
	* builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
	instead of src/base/ftmac.c
	* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
	* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
	that cannot be built at present.

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

	* src/base/ftobjs.c: Improvement of resource fork handler for
	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.

	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'
	or `type'.

	* builds/freetype.mk (version): Extracted from freetype.h, using
	GNU make's built-in string functions.
	(refdoc): Use $(version) instead of static version number.

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

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

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

	* src/tools/apinames (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>

	trying to render into a zero-width/height bitmap, not an error code.

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

	* src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType
	ones instead.

	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

	`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_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
	Other minor improvements.

	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>

	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

	(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.

	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.

	Add a new API to support color filtering of subpixel glyph bitmaps.
	In a default build, the function `FT_Library_SetLcdFilter' returns

	* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
	`item_size == 0' as well -- though this sounds weird, it can
	theoretically happen.  This fixes Savannah bug #16669.

	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
	of `face->num_glyphs' which missed the last glyph, due to
	the offset-by-1 computation, since the PFR format doesn't
	guarantee that glyph index 0 corresponds to the `missing
	glyph.  This fixes Savannah bug #16668.

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

	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
	`-no-undefined'.  Reported by Christian Biesinger.

2006-05-19  Brian Weed  <bw@imaginengine.com>

	* builds/win32/visualc/freetype.dsp: Release libraries no longer
	have debug information, and debug libraries use `C7 compatible'
	debug info.

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

	Apply patch by Derek Clegg to fix two memory leaks in the MacOS
	resource fork handler.  This fixes Savannah bug #16631.

	* src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
	`FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

	* src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):
	Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.

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

	* build/unix/configure.raw: Add a fallback to disable Carbon
	dependency, if configured with no options on Mac OS X.

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

	* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
	its content cannot be parsed as supported font.  This fixes
	the second part of Savannah bug #16590.

2006-05-18  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

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

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

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

	The resulting speed-up is about 25%.


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

	* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
	New functions.
	(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
	[TEST]: Remove.

	* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
	code.

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

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

	* src/autofit/aftypes.h: Updated.

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

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

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

	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_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.

	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.


	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
	used to detect rogue clients from 4 to 16.  This is to prevent some
	segmentation faults with fonts like `KozMinProVI-Regular.otf' which
	comes from the Japanese Adobe Reader Asian Font pack.

2007-05-17  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
	fixes the first part of Savannah bug #16590.

2006-05-16  Werner Lemberg  <wl@gnu.org>

	* docs/PROBLEMS: Updated icl issues.
