ChangeLog

2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/rules.mk: Add conditional source to BASE_SRC, for
	`make multi' on Mac OS X. If the macro $(ftmac_c) is defined,
	$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In normal build,
	the lack of ftmac.c in BASE_SRC is not serious because ftbase.c
	includes ftmac.c.
	* builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
	* builds/unix/configure.raw: Add procedure to set up appropriate
	value of $(ftmac_c) with the consideration of the availability
	of Carbon framework.

2008-09-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/Jamfile: Add target for multi build by jam on Mac OS X.
	* src/base/ftobjs.c (FT_New_Face): Fix the condition to include
	this function for MPW building. It is synchronized the condition
	to include ftmac.c source into ftbase.c.

2008-09-22  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
	cff_decoder_parse_charstrings): Handle (invalid)
	`callothersubr' and `pop' instructions.

2008-09-22  John Tytgat  <John.Tytgat@esko.com>

	Fix Savannah bug #24307.

	* include/freetype/internal/t1types.h (CID_FaceRec),
	src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.

2008-09-21  Werner Lemberg  <wl@gnu.org>

	* src/smooth/ftgrays.c (gray_raster_render): Don't dereference
	`target_map' if FT_RASTER_FLAG_DIRECT is set.  Problem reported by
	Stephan T. Lavavej <stl@nuwen.net>.

2008-09-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/otvalid/Jamfile: Add missing target `otvmath' for multi build
	by jam.
	* src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
	jam.

2008-09-20  Werner Lemberg  <wl@gnu.org>

	* src/smooth/ftgrays.c (gray_find_cell): Fix threshold.  The values
	passed to this function are already `normalized'.  Problem reported
	by Stephan T. Lavavej <stl@nuwen.net>.

	* docs/CHANGES: Document it.

2008-09-20  Werner Lemberg  <wl@gnu.org>

	* src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
	(FT_Outline_Decompose): Decorate with tracing messages.

	* src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
	FT_DEBUG_LEVEL_TRACE.
	[_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
	stdarg.h.

	(FT_TRACE) [_STANDALONE_]: Remove.
	(FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
	(FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
	(FT_ERROR) [_STANDALONE_]: Updated.

	(gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
	Use FT_TRACE7.
	(gray_dump_cells): Make it `static void'.
	(gray_convert_glyph): Use FT_TRACE7.

	(FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
	ftoutln.c.

	* src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
	FT_ERROR_BASE.

	* docs/formats.txt: Updated.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
	CID-keyed font support.
	* builds/mac/ftmac.c: Ditto.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
	sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
	`open_face_from_buffer' frees the passed buffer if it cannot open a
	face from the buffer, so the caller must not free it.

2008-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
	for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
	(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
	table in sfnt table directory.  It is used before loading TrueType
	font driver.

	* docs/CHANGES: Add note about the current status of sfnt-wrapped
	Type1 and sfnt-wrapped CID-keyed font support.

2008-09-18  Werner Lemberg  <wl@gnu.org>

	* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
	orthogonality (ft_free and ft_sfree could belong to different memory
	pools).  This fixes Savannah bug #24297.

2008-09-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
	in ttags.h instead of numerical value 0x4F54544FL.

2008-09-16  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffgload.h, src/cff/cffgload.c
	(cff_decoder_set_width_only): Eliminate function call.

2008-09-15  George Williams  <gww@silcom.com>

	Fix Savannah bug #24179, reported by Bram Tassyns.

	* src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
	of default values.

2008-09-15  Werner Lemberg  <wl@gnu.org>

	* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
	and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
	prevent unconditional definition.  This fixes Savannah bug #24241.

	* src/psnames/pstables.h: Regenerated.

2008-09-13  Werner Lemberg  <wl@gnu.org>

	* autogen.sh, builds/unix/configure.raw,
	include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
	beautifying.

	* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
	include/freetype/ftlcdfil.h: Protect against FreeType 1.
	Some other minor fixes.

	* devel/ftoption.h: Synchronize with
	include/freetype/config/ftoption.h.

2008-09-11  Werner Lemberg  <wl@gnu.org>

	* src/base/ftbase.c: Include ftadvanc.c.

2008-09-11  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/ftconfig.in: Duplicate the cpp computation of
	FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
	(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro.  If defined, the cpp
	computation is disabled and the statically configured sizes are
	used.  This fixes Savannah bug #21250.

	* builds/unix/configure.raw: Add the checks to compare the cpp
	computation results of the bit length of int and long versus the
	sizes detected by running `configure'.  If the results are
	different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
	results.
	New option --{enable|disable}-biarch-config is added to define or
	undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.

2008-09-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
	ApplicationService framework is missing.  Although this value is not
	used in building of FreeType2, it is written in `freetype2.pc' and
	`freetype-config'.

2008-09-01  david turner  <david@freetype.org>

	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
	index to mean `use default cached FT_Face's charmap'.  This fixes
	Savannah bug #22625.
	* include/freetype/ftcache.h: Document it.


	Make FT_MulFix an inlined function.  This is done to speed up
	FreeType a little (on x86 3% when loading+hinting, 10% when
	rendering, ARM savings are more important though).  Disable this by
	undefining FT_CONFIG_OPTION_INLINE_MULFIX.

	Use of assembler code can now be controlled with
	FT_CONFIG_OPTION_NO_ASSEMBLER.

	* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
	implementation.
	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
	implementation taken from `ftcalc.c'.
	[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
	which is defined to the platform-specific assembler implementation
	of FT_MulFix.
	[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
	(FT_MULFIX_INLINED): New macro.

	* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
	FT_CONFIG_OPTION_INLINE_MULFIX): New macros.

	* include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.

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


	Add a new header named FT_ADVANCES_H declaring some new APIs to
	extract the advances of one or more glyphs without necessarily
	loading their outlines.  Also provide `fast loaders' for the
	TrueType, Type1, and CFF font drivers (more to come later).

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

	* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
	* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.

	* include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
	`flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
	respectively.

	* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
	ftadvanc.c.

	* src/cff/cffdrivr.c (cff_get_advances): New function.
	(cff_driver_class): Register it.

	* src/cff/cffgload.c (cff_decoder_set_width_only): New function.
	(cff_decoder_parse_charstrings): Handle `width_only'.
	(cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.

	* src/cff/cffgload.h (cff_decoder): New element `width_only'.
	(cff_decoder_set_width_only): New declaration.

	* src/truetype/ttdriver.c (tt_get_advances): New function.
	(tt_driver_class): Register it.

	* src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
	(TT_Get_HMetrics, TT_Get_VMetrics): This.
	Update callers.
	* src/truetype/ttgload.h: Declare them.

	* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
	function.
	* src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.


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

	* autogen.sh: Implement it.
	(get_major_version, get_minor_version, get_patch_version,
	compare_to_minimum_version, check_tool_version): New auxiliary
	functions.

	* README.CVS: Document it.

2008-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
	ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).

2008-08-28  Werner Lemberg  <wl@gnu.org>

	* src/type1/t1load.c (parse_encoding): Protect against infinite
	loop.  This fixes Savannah bug #24150 (where a patch has been posted
	too).

2008-08-23  Werner Lemberg  <wl@gnu.org>

	* src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
	(afm_compare_kern_pairs): Fix comparison.  This fixes Savannah bug
	#24119.

2008-08-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
	even if passed library or arguments are invalid.  This fixes a bug
	that an uninitialized stream is freed when an invalid library handle
	is passed.  Originally proposed by Mike Fabian, 2008/08/18 on
	freetype-devel.
	(FT_Open_Face): Ditto (stream).
	(load_face_in_embedded_rfork): Ditto (stream2).

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c: Add a fallback to guess the availability of the
	`ResourceIndex' type.  It is used when built without configure
	(e.g., a build with Jam).
	* builds/mac/ftmac.c: Ditto.
	* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
	explicitly, even if `ResourceIndex' is unavailable.

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: In checking of Mac OS X features,
	all-in-one header file `Carbon.h' is replaced by the minimum
	header file `CoreServices.h', similar to current src/base/ftmac.c.

2008-08-18  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
	sub-header when its code_count is 0.  Many Japanese Dynalab fonts
	include such an empty sub-header (code_count == 0, first_code == 0
	delta == 0, but offset != 0) as the second sub-header in SJIS cmap.

2008-08-04  Werner Lemberg  <wl@gnu.org>

	* src/type1/t1tokens.h: Handle `ForceBold' keyword.  This fixes
	Savannah bug #23995.

	* src/cid/cidload.c (parse_expansion_factor): New callback function.
	(cid_field_records): Use it for `ExpansionFactor'.
	* src/cod/cidtoken.h: Handle `ForceBold' keyword.
	Don't handle `ExpansionFactor'.

2008-08-04  Bram Tassyns  <bramt@enfocus.be>

	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
	resulted in incorrect scaling.  This fixes Savannah bug #23973.

2008-08-04  Werner Lemberg  <wl@gnu.org>

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

	* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
	adjust table count.
	Add more trace messages.
	(tt_face_load_font_dir): Updated.

2008-07-30  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
	assume that the first argument on the stack is the bottom-most
	element.  Two reasons:

	  o According to people from Adobe it is missing in the Type 2
	    specification that pushing of additional, superfluous arguments
	    on the stack is prohibited.

	  o Acroread in general handles fonts differently, namely by popping
	    the number of arguments needed for a particular operand (as a PS
	    interpreter would do).  In case of buggy fonts this causes a
	    different interpretation which of the elements on the stack are
	    superfluous and which not.

	Since there are CFF subfonts (embedded in PDFs) which rely on
	Acroread's behaviour, FreeType now does the same.

2008-07-27  Werner Lemberg  <wl@gnu.org>

	Add extra mappings for `Tcommaaccent' and `tcommaaccent'.  This
	fixes Savanna bug #23940.

	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
	(EXTRA_GLYPH_LIST_SIZE): This.
	Increase by 2.
	(ft_wgl_extra_unicodes): Rename to...
	(ft_extra_glyph_unicodes): This.
	Add two code values.
	(ft_wgl_extra_glyph_names): Rename to...
	(ft_extra_glyph_names): This.
	Add two glyphs.
	(ft_wgl_extra_glyph_name_offsets): Rename to...
	(ft_extra_glyph_name_offsets): This.
	Add two offsets.

	(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
	(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
	Updated.
	(ps_unicodes_init): Updated.

2008-07-26  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffgload.c (cff_decoder_prepare,
	cff_decoder_parse_charstrings): Improve debug output.

2008-07-22  Martin McBride  <mmcbride@emtex.com>

	* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
	tt_cmap4_char_map_binary): Handle fonts which treat the last segment
	specially.  According to the specification, such fonts would be
	invalid but acroread accepts them.

2008-07-16  Jon Foster  <Jon.Foster@cabot.co.uk>

	* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.

	* src/base/ftcalc.c (FT_MulFix): Fix portability issue.

	* src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
	Fix compiler warning.

2008-07-16  Werner Lemberg  <wl@gnu.org>

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

	* src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
	Invert sids table only if `pure_cff' is set.
	* src/cff/cffload.h: Udpated.

	* src/cff/cffobjs.c (cff_face_init): Updated.
	Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.

	* docs/CHANGES: Updated.

2008-07-09  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
	where num_locations < num_glyphs.  Problem reported by Ding Li.

2008-07-05  Werner Lemberg  <wl@gnu.org>

	Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
	newer.  This fixes Savannah bug #23648.

	* configure: zsh doesn't like ${1+"$@"}.
	Update needed GNU make version.
	* builds/toplevel.mk: Check for `$(eval ...)'.
	* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
	it.

2008-07-04  Werner Lemberg  <wl@gnu.org>

	* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
	pixel, only check for dropouts if neither start nor end point lies
	on a pixel center.  This fixes Savannah bug #23762.

2008-06-29  Werner Lemberg  <wl@gnu.org>

	* Version 2.3.7 released.
	=========================


	Tag sources with `VER-2-3-7'.

	* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
	version number to 2.3.7.

	* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
	builds/win32/visualc/freetype.dsp,
	builds/win32/visualc/freetype.vcproj,
	builds/win32/visualce/index.html,
	builds/win32/visualce/freetype.dsp,
	builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.

	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

	* builds/unix/configure.raw (version_info): Set to 9:18:3.

	* docs/release: Updated.

2008-06-28  Werner Lemberg  <wl@gnu.org>

	* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
	* src/ftcalc.c: Here.  This fixes Savannah bug #23729.

2008-06-27  Werner Lemberg  <wl@gnu.org>

	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
	Horizontal_Gray_Sweep_Drop): Test for intersections which
	degenerate to a single point can be ignored; this has been confirmed
	by Greg Hitchcock from Microsoft.  (This was commented out code.)

2008-06-26  Werner Lemberg  <wl@gnu.org>

	Improve navigation in API reference.

	* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
	(html_header_6): This.
	(html_header_3, html_header_3i, html_header_4, html_header_5,
	html_header_5t): New strings.
	(toc_footer_start, toc_footer_end): New strings.
	(HtmlFormatter::html_header): Updated.
	(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
	New strings.
	(HtmlFormatter::index_enter): Use `html_index_header'.
	(HtmlFormatter::index_exit): Print `html_footer'.
	(HtmlFormatter::toc_enter): Use `html_toc_header'.
	(HtmlFormatter::toc_exit): Print proper footer.

	Convert ~ to non-breakable space.

	* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
	Update header files accordingly.

2008-06-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
	and define HAVE_TYPE_RESOURCE_INDEX if it is defined.  Mac OS X 10.5
	bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
	ResourceIndex type definition.  The macro does not inform the type
	availability.
	* src/base/ftmac.c: More parentheses are inserted to clarify the
	conditionals to disable legacy APIs in `10.5 and later' cases.  If
	HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.

2008-06-24  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
	mode.

	* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
	Draw_Sweep): No-dropout mode is value 2, not value 0.
	(Draw_Sweep): Really skip dropout handling for no-dropout mode.

2008-06-24  Werner Lemberg  <wl@gnu.org>

	* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
	if it consists of one point only.  Based on a patch from Savannah
	bug #23683 (from John Tytgat).

2008-06-22  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
	with IS_HINTED.

	* docs/CHANGES: Updated.

2008-06-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
	but LDFLAGS does not, import it to LDFLAGS.  The option is used to
	specify non-default SDK on Mac OS X (e.g., universal binary SDK for
	Mac OS X 10.4 on PowerPC platform).  Although Apple TechNote 2137
	recommends to add the option only to CFLAGS, LDFLAGS should include
	it because libfreetype.la is built with -no-undefined.  This fixes a
	bug reported by Ryan Schmidt in MacPorts,
	http://trac.macports.org/ticket/15331.

2008-06-21  Werner Lemberg  <wl@gnu.org>

	Enable access to the various dropout rules of the B&W rasterizer.
	Pass dropout rules from the TT bytecode interpreter to the
	rasterizer.

	* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
	FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.

	* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
	Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
	OpenType specification.
	Fix mode 4 computation.
	(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

	* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
	mode to FT_OUTLINE_XXX flags.

	* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

2008-06-19  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffobjs.c (cff_face_init): Compute final
	`dict->units_per_em' value before assigning it to
	`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are
	scaled incorrectly if the font matrix is non-standard.  This fixes
	Savannah bug #23630.

	* docs/CHANGES: Updated.

2008-06-15  George Williams  <gww@silcom.com>

	* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set

	specification.

2008-06-15  Werner Lemberg  <wl@gnu.org>

2008-06-06  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
	correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.

2008-06-03  Werner Lemberg  <wl@gnu.org>

	* include/freetype/ftcache.h (FTC_FaceID): Change type back to
	FT_Pointer.  Reported by Ian Britten <britten@caris.com>.

2008-06-02  Werner Lemberg  <wl@gnu.org>

	Emit header info for defined FreeType objects in reference.

	* src/tools/docmaker/content.py (re_header_macro): New regexp.
	(ContentProcessor::__init__): Initialize new dictionary `headers'.
	(DocBlock::__init__): Collect macro header definitions.

	* src/tools/docmaker/tohtml.py (header_location_header,
	header_location_footer): New strings.

	(HtmlFormatter::print_html_field): Don't emit paragraph tags.
	(HtmlFormatter::print_html_field_list): Emit empty paragraph.
	(HtmlFormatter::block_enter): Emit header info.

2008-06-01  Werner Lemberg  <wl@gnu.org>

	* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
	FT_INCREMENTAL_H): Added.

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

	found.

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

	* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
	original, unscaled input values.  Confirmed by Greg Hitchcock from
	Microsoft.

2008-05-27  Werner Lemberg  <wl@gnu.org>

	* src/tools/docmaker/tohtml.py (block_footer_start,
	block_footer_middle): Beautify output.

2008-05-25  Werner Lemberg  <wl@gnu.org>

	* src/raster/ftraster.c (fc_black_render): Return 0 when we are

	* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
	of the graphics state for subglyphs to...
	(TT_Hint_Glyph): This function.
	Hinting instructions for a composite glyph apparently refer to the
	just hinted subglyphs, not the unhinted, unscaled outline.  This
	seems to fix Savannah bugs #20973 and (at least partially) #23310.

2008-05-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
	`aface' is returned by FT_New_Face_From_FOND().  The patch was
	proposed by an anonymous reporter of Savannah bug #23204.

2008-05-18  Werner Lemberg  <wl@gnu.org>

	* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
	correction for pixel boundary.  Without this patch, the effect can
	be cumulative under certain circumstances, making glyphs taller and
	taller after each call.  This fixes Savannah bug #19976.

2008-05-18  Werner Lemberg  <wl@gnu.org>

	* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
	This fixes Savannah bug #23280.

	* docs/CHANGES: Updated.

2008-05-18  David Turner  <david@freetype.org>

	* src/psnames/psmodule.c (ft_wgl_extra_unicodes,
	ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
	ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
	declarations non-global.

	* src/type1/t1load.c: Add missing comment.

2008-05-17  Sam Hocevar  <samh>

	* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
	glyphs correctly.  Patch from Savannah bug #23277.

2008-05-16  Werner Lemberg  <wl@gnu.org>

	* docs/CHANGES: Updated.

2008-05-16  Sergey Tolstov  <stolstov@esri.com>

	Improve support for WGL4 encoded fonts.

	* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
	(ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
	ft_wgl_extra_glyph_name_offsets): New arrays.

	(ps_unicodes_init): Use them to add additional Unicode mappings.

2008-05-15  Werner Lemberg  <wl@gnu.org>

	* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
	<op_closepath>: `closepath' without a path is a no-op, not an error
	(cf. the PS reference manual).

	Reported by Martin McBride.

2008-05-15  Werner Lemberg  <wl@gnu.org>

	* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.

2008-05-15  Werner Lemberg  <wl@gnu.org>

	* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
	which contains a single but empty entry.  This is technically
	invalid (since it must end with `return'), but...

	Reported by Martin McBride.

2008-05-14  Werner Lemberg  <wl@gnu.org>

	Finish fix of scaling bug of CID-keyed CFF subfonts.

	* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
	(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
	functions.

	* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
	provide global hinting data for both the top-font and all subfonts
	(with proper scaling).

	* src/cff/cffobjs.c (cff_make_private_dict): New function, using
	code from `cff_size_init'.
	(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
	Use CFF_Internal and handle subfonts.
	(cff_face_init): Handle top-dict and subfont matrices correctly;
	apply some heuristic in case of unlikely matrix concatenation
	results.  This has been discussed with people from Adobe (thanks
	goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
	and not correct.

	* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

	* src/cff/cffgload.c (cff_builder_init): Updated.
	(cff_decoder_prepare): Handle hints globals for subfonts.

	* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
	(cff_parse_font_matrix): Use it.

	* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
	FT_ULong.

	* docs/CHANGES: Document it.

2008-05-13  Werner Lemberg  <wl@gnu.org>

	* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
	Handle case `face_index < 0'.
	* docs/CHANGES: Document it.

2008-05-04  Werner Lemberg  <wl@gnu.org>

	First steps to fix the scaling bug of CID-keyed CFF subfonts,
	reported by Ding Li on 2008/03/28 on freetype-devel.

	* src/base/cff/cffparse.c (power_tens): New array.
	(cff_parse_real): Rewritten to introduce a fourth parameter which
	returns the `scaling' of the real number so that we have no
	precision loss.  This is not used yet.
	Update all callers.
	(cff_parse_fixed_thousand): Replace with...
	(cff_parse_fixed_scaled): This function.  Update all callers.

2008-05-03  Werner Lemberg  <wl@gnu.org>

	* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
	transformation since it recursively calls FT_Load_Glyph.  This fixes
	Savannah bug #23143.

2008-04-26  Werner Lemberg  <wl@gnu.org>

	* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'

	bug #22909.

2008-04-13  Werner Lemberg  <wl@gnu.org>

	* src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
	integer part is zero.

2008-04-01  Werner Lemberg  <wl@gnu.org>

	Fix compilation with g++ 4.1 (with both `single' and `multi'
	targets).

	* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
	which is crossed by a `goto'.

	* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.

2008-03-31  Werner Lemberg  <wl@gnu.org>

	Fix support for subsetted CID-keyed CFFs.

	* builds/compiler/visualc.mk (CFLAGS): Remove /W5.
	(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.

2008-03-21  Laurence Darby  <ldarby>

	* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'.  Patch from
	Savannah bug #22675.

2008-03-13  Derek Clegg  <dclegg@apple.com>

	* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop. 
	Patch from Savannah bug #22541.

2008-03-03  Masatoshi Kimura  <VYV03354@nifty.ne.jp>

	* src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
	tt_cmap14_find_variant): Return correct value.
	(tt_cmap14_variant_chars): Fix check for `di'.

2008-02-29  Wermer Lemberg  <wl@gnu.org>

	* docs/CHANGES: Updated.

2008-02-29  Wolf

	Add build support for symbian platform.  From Savannah bug #22440.

	* builds/symbian/*: New files.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
	synthesis.  For any face of a specified FOND, always the name for
	the first face was used.  Except of a FOND that refers multiple
	Type1 font files, wrong synthesized font names are not used at all,
	so this is an invisible bug.  A few limit checks are added too.

	* builds/mac/ftmac.c: Ditto.

2008-02-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Split compiler option to link Carbon
	frameworks to one option for CoreServices framework and another
	option for ApplicationServices framework.  The split options can be
	managed by GNU libtool to avoid unrequired duplication when FreeType
	is linked with other applications.  Suggested by Daniel Macks,
	Savannah bug #22366.

2008-02-18  Victor Stinner  <victor.stinner@haypocalc.com>

	* src/truetype/ttinterp.c (Ins_IUP): Check number of points.  Fix
	from Savannah bug #22356.

2008-02-17  Jonathan Blow  <jon@number-none.com>

	* src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
	Check for valid callback pointers.

2008-02-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

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

	* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.

2008-02-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
	inclusion styles.  Now it always includes src/base/ftmac.c;
	builds/mac/ftmac.c is never included in any configuration.

	* builds/unix/configure.raw: Print warning if configure is executed
	with options to specify Carbon functionalities explicitly.

	* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
	included automatically and manual replacement is required.

2008-02-11  Werner Lemberg  <wl@gnu.org>

	* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
	(dos_setup), builds/freetype.mk (clean_project_dos,
	distclean_project_dos): Don't use \ but $(SEP).  Reported by Duncan
	Murdoch.

2008-01-18  Sylvain Pasche  <sylvain.pasche@gmail.com>

	* src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to
	mention intra-pixel algorithm.

	* include/freetype/freetype.h (FT_Render_Mode): Mention that
	FT_Library_SetLcdFilter can be used to reduce fringes.

2008-01-16  Werner Lemberg  <wl@gnu.org>

	* src/raster/ftraster.c (ft_black_render): Check `outline' before
	using it.  Reported by Allan Yang.

2008-01-12  Werner Lemberg  <wl@gnu.org>

	* src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.

2008-01-12  Allan Yang, Jian Hua - SH  <Allan.Yang@fmc.fujitsu.com>

	* src/raster/ftraster.c (ft_black_init)
	[FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.

2008-01-10  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttgload.c (load_truetype_glyph): Handle the case
	where the number of contours in a simple glyph is zero (and which
	does contain an entry in the `glyf' table).  This fixes Savannah bug
	#21990.

2008-01-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Formatting suggested by Sean McBride.

	* builds/mac/ftmac.c: Formatting (tab expanded).
	* src/autofit/afindic.c: Ditto.
	* src/base/ftcid.c: Ditto.
	* src/base/ftmac.c: Ditto.

2007-12-30  Werner Lemberg  <wl@gnu.org>

	* src/smooth/ftgrays.c (gray_raster_render): Check `outline'
	correctly.

2007-12-21  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Improvement of POSIX resource-fork accessor to load unsorted
	references in a resource.  In HelveLTMM (resource-fork PostScript
	Type1 font bundled with Mac OS X since 10.3.x), the appearance order
	of PFB chunks is not sorted; sorting the chunks by reference IDs is
	required.

	* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
	type to store a pair of reference ID and offset to the chunk.

	* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
	sort FT_RFork_Ref by their reference IDs.

	(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
	sorted by reference ID.

2007-12-14  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
	division too early; otherwise the most significant digit(s) of the
	final result are lost as the value is truncated to an integer.  This
	fixes Savannah bug #21794 (where the patch has been posted too).

2007-12-06  Fix  <4d876b82@gmail.com>

	Pass options from one configure script to another as-is (not
	expanded).  This is needed for options like
	--includedir='${prefix}/include'.

	* builds/unix/detect.mk, configure: Prevent argument expansion in
	call to the (real) `configure' script.

2007-12-06  Werner Lemberg  <wl@gnu.org>

	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
	TT_USE_BYTECODE_INTERPRETER isn't defined.

2007-12-06  Werner Lemberg  <wl@gnu.org>

	There exist CFFs which contain opcodes for the Type 1 operators
	`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
	However, it doesn't harm to support them.

	* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
	`cff_op_closepath.'
	(cff_argument_counts): Ditto.

	(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
	and 13 (hsbw) which are invalid in Type 2 charstrings.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
	support new pathname syntax `..namedfork/rsrc' to access a resource
	fork on Mac OS X.  The legacy syntax `/rsrc' does not work on
	case-sensitive HFS+.
	(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
	buffer size to store a pathname.
	* include/freetype/internal/ftrfork.h: Increment the number of
	resource fork guessing rule.

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Improve the compile tests to search
	Carbon functions.
	* builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
	proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).

2007-12-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	The documents and comments for Mac OS X are improved by Sean
	McBride.

	* src/base/ftmac.c: Fix a comment.
	* include/freetype/ftmac.h: Ditto.
	* docs/INSTALL.MAC: Improve English and add comment on lowest
	system version specified by MACOSX_DEPLOYMENT_TARGET.

2007-12-04  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
	concatenate error codes.
	* src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.

2007-12-04  Graham Asher  <graham.asher@btinternet.com>

	* src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
	concatenate error codes.

2007-12-04  Sean McBride  <sean@rogue-research.com>

	* src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
	warning.

2007-11-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Fix MacOS legacy font support by Masatake Yamato on Mac OS X.  It is
	not working since 2.3.5.  In FT_Open_New(), if FT_New_Stream()
	cannot mmap() the specified file and cannot seek to head of the
	specified file, it returns NULL stream and FT_Open_New() returns the
	error immediately.  On MacOS, most legacy MacOS fonts fall into such
	a scenario because their data forks are zero-sized and cannot be
	sought.  To proceed to guessing of resource fork fonts, the
	functions for legacy MacOS font must properly handle the NULL stream
	returned by FT_New_Stream().

	* src/base/ftobjs.c (IsMacBinary): Return error
	FT_Err_Invalid_Stream_Operation immediately when NULL stream is
	passed.
	(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
	to fallback.  Originally, legacy MacOS font is tested in the cases
	of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
	or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
	.dfont header is combined).  Now the case of
	FT_Err_Cannot_Open_Stream is included.

	* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
	skip FT_Stream_Seek(), which seeks to the head of stream, and
	proceed to unit testing of raccess_guess_XXX().  FT_Stream_Seek()
	for a NULL stream causes a Bus error on Mac OS X.
	(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
	immediately if passed stream is NULL.
	(raccess_guess_apple_single): Ditto.

2007-11-16  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Fix for Carbon incompatibilities since Mac OS X 10.5,
	proposed by Sean McBride.

	* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.

	* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
	FT_GetFilePath_From_Mac_ATS_Name.  Since Mac OS X 10.5, calling
	Carbon functions from a forked process is classified as unsafe
	by Apple.  All Carbon-dependent functions should be deprecated.

	* src/base/ftmac.c: Use essential header files <Carbon/Carbon.h>
	and <ApplicationServices/ApplicationServices.h> instead of
	all-in-one header file <CoreServices/CoreServices.h>.

	Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
	genuine macro PATH_MAX.

	Add fallback macro for kATSOptionFlagsUnRestrictedScope which
	is not found in Mac OS X 10.0.

	Multi-character constants ('POST', 'sfnt' etc) are replaced by
	64bit constants calculated by FT_MAKE_TAG() macro.

	For the index in the segment of resource fork, new portable
	type ResourceIndex is introduced for better compatibility.
	This type is since Mac OS X 10.5, so it is defined as short
	when built on older platforms.

	(FT_ATSFontGetFileReference): If build target is only the systems
	10.5 and newer, it calls Apple genuine ATSFontGetFileReference().

	(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
	and newer or 64bit platform, because legacy type FSSpec type is
	removed completely.

	(FT_New_Face_From_FSSpec): Ditto.

2007-11-01  Werner Lemberg  <wl@gnu.org>

	* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere.  This
	fixes Savannah bug #21485.

2007-10-29  Daniel Svoboda  <dasvo@planeta@cz>

	* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
	can handle the font at all, then check `face_index'.  Otherwise, the
	driver might return the wrong error code.  This fixes Savannah bug
	#21468.

2007-10-21  Werner Lemberg  <wl@gnu.org>

	* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
	support for bit 8 of the `fsSelection' field in the `OS/2' table. 
	MS is already using this; hopefully, this becomes part of OpenType
	1.5.
	Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
	(WWS_SUBFAMILY).

2007-10-20  Werner Lemberg  <wl@gnu.org>

	* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
	Add `td.left' element to CSS.
	(toc_section_enter): Use it.

2007-10-18  David Turner  <david@freetype.org>

	* include/freetype/freetype.h, src/base/ftobjs.c: Rename API
	functions related to cmap type 14 support to the
	`FT_Object_ActionName' scheme:

	  FT_Get_Char_Variant_index     -> FT_Face_GetCharVariantIndex
	  FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
	  FT_Get_Variant_Selectors      -> FT_Face_GetVariantSelectors
	  FT_Get_Variants_Of_Char       -> FT_Face_GetVariantsOfChar
	  FT_Get_Chars_Of_Variant       -> FT_Face_GetCharsOfVariant

	Update documentation accordingly.

	* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
	Make the code a little more consistent with FreeType coding
	conventions and modify the cmap14 functions that returned a newly
	allocated array to use a persistent vector from the TT_CMap14 object
	instead.

	(TT_CMap14Rec): Provide array and auxiliary data for result.
	(tt_cmap14_done, tt_cmap14_ensure): New functions.

	(tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary,
	tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant,
	tt_cmap14_char_var_index, tt_cmap14_variants,

	* src/base/ftobjs.c (find_unicode_charmap): If search for a UCS-4
	charmap fails, do the loop again while searching a UCS-2 charmap.
	This favours MS charmaps over Apple ones.

2007-08-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/base/ftmac.c: Introduction of abstract `short' data types,

	same as the other value.

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

	<daniel-gl@gmx.net>.

	* src/type1/t1afm.c (T1_Read_PFM): Read kerning values as 16-bit

	* src/base/ftbase.c: Fix to use builds/mac/ftmac.c, if configured
	`--with-fsspec' etc.  Replace #include "ftmac.c" with
	#include <ftmac.c>.

2007-02-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* include/freetype/ftmac.h (FT_GetFilePath_From_Mac_ATS_Name):
	Introduced as replacement of FT_GetFile_From_Mac_ATS_Name.

2007-02-01  Alexei Podtelezhnikov  <apodtele@gmail.com>

	* builds/unix/freetype2.m4 (AC_CHECK_FT2): Fix spelling of warning
	message.

	* src/gxvalid/gxvmort1.c
	(gxv_mort_subtable_type1_substTable_validate): Fix debugging

2007-01-31  Werner Lemberg  <wl@gnu.org>


	* 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.
	(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.

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

	* docs/release: Updated -- Savannah uses a new uploading scheme.

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

	* 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.


	Fix and enable the warper to improve `light' hinting mode.  This is
	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.

	* 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,

	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

	* src/cff/cffdrvr.c (cff_ps_get_font_info): New function.
	(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
	with C++ compiler.

	* src/autofit/afhints.c (af_glyph_hints_dump_segments,
	af_glyph_hints_dump_edges): Ditto.

	* src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
	`modules.cfg').

	* src/sfnt/ttsbit0.h: Remove.

	* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.

2007-01-12  David Turner  <david@freetype.org>

2007-01-11  David Turner  <david@freetype.org>

	* docs/CHANGES: Small update.

	* builds/unix/configure.raw (version_info): Set to 9:11:3.

	* 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,
	and we must call `glibtoolize', since `libtoolize' doesn't exist.

2007-01-10  David Turner  <david@freetype.org>

	* all-sources: Tag all sources with VER-2-3-0-RC1 and
	VER-2-3-0.

	which created an endless loop with some malformed font files.

2007-01-10  Derek Clegg  <dclegg@apple.com>

	* src/type1/t1load.c (T1_Get_MM_Var): Always return fixed point
	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.

	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for
	<freetype/ftgasp.h>.

	* src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),

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.

	(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'.

	(cff_index_done): This.  Update all callers.
	(cff_index_get_pointers, cff_index_access_element): Updated to use
	stream offsets.

	* 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.

	function.
	Check uniqueness of the gid pairs.
	(gxv_kern_subtable_fmt0_validate): Move some code to
	`gxv_kern_subtable_fmt0_pairs_validate'.

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

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

	* 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_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.

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

	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

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.

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

	* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore

	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.

	* 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.

	(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.

	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.

	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/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

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

	loader.

	* src/smooth/ftgrays.c: Optmize the performance of the anti-aliased
	rasterizer.  The speed improvement is between 15% and 25%, depending

	(TCell): Redefine.
	(TRaster): New members `buffer', `buffer_size', `ycells', `ycount'.

2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>

	The Type 1 parser now skips over top-level procedures as required

	(count_faces): Call `HUnlock' after all FOND utilization.

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

	Public API of TrueTypeGX, OpenType, and classic kern table validator
	should return `FT_Err_Unimplemented_Feature' if validation service
	is unavailable (disabled in `modules.cfg').  It is originally
	suggested by David Turner, cf.
	http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

	* src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return

2006-06-06  David Turner  <david@freetype.org>

	Fix memory leak described in Savannah bug #16759.

	We change `ps_unicodes_init' so that it also takes a
	`free_glyph_name' callback to release the glyph names returned by
	`get_glyph_name'

	Renamed to ...
	(PS_GetGlyphNameFunc): This.

	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

	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.

	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.

	[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%.

	(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.

	Improve performance.

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

	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.
