这是一个开放源代码的与WINNT/WIN2K/WIN2003兼容的操作系统

	* src/psaux/afmparse.c (afm_parser_read_vals): Use double casting
	to avoid compiler warnings regarding type-punning.

2006-01-16  Chia-I Wu  <[e-mail]>

	* src/psaux/afmparse.c, src/psaux/afmparse.h: New files which
	implement an AFM parser.

	* src/psaux/psconv.c, src/psaux/psconv.h: New files to provide
	conversion functions (e.g., PS real number => FT_Fixed) for the
	PS_Parser and AFM_Parser.  Some of the functions are taken, with
	some modifications, from the file psobjs.c.

	* src/psaux/psobjs.c: Use functions from psconv.c.

	* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Add
	`AFM_Parser' to the `psaux' service.

	those new files.

	* src/tools/test_afm.c: A test program for AFM parser.

	* include/freetype/internal/services/svkern.h: New file providing a
	`Kerning' service.  It is currently only used to get the track
	kerning information.

	* include/freetype/internal/ftserv.h (FT_SERVICE_KERNING_H): New
	macro.

	* src/type1/t1driver.c, src/type1/t1objs.c, src/type1/t1afm.c,
	src/type1/t1afm.h: Update to use the AFM parser.
	Provide the `Kerning' service.

	* include/freetype/freetype.h, src/base/ftobjs.c: New API
	`FT_Get_Track_Kerning'.

2006-01-15  Chia-I Wu  <[e-mail]>

	src/pcf/pcfdrivr.c, src/type1/t1gload.c, src/winfonts/winfnt.c:
	s/ft_fake_vertical_metrics/ft_synthesize_vertical_metrics/.

	fonts not having this info.

2006-01-15  Chia-I Wu  <[e-mail]>

	* include/freetype/internal/ftobjs.h (ft_fake_vertical_metrics),

	* src/cff/cffgload.c, src/cid/cidgload.c, src/pcf/pcfdrivr.c,
	src/type1/t1gload.c, src/winfonts/winfnt.c: Fake vertical metrics,
	which are monotone.

	* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
	formattings in vertical metrics faking.  There is still room for
	improvements (and so does the CFF module).

2006-01-15  Chia-I Wu  <[e-mail]>

	* src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/pcf/pcfdrivr.c
	(PCF_Glyph_Load), src/winfonts/winfnt.c (FNT_Load_Glyph): Don't set
	the linear advance fields as they are only used by the outline
	glyphs.

	* include/freetype/freetype.h: Documentation updates and
	clarifications.
	The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
	change need be made to the code.

	* src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and
	decide whether to use the auto-hinter according to documentation.
	There should to be no real difference.
	Some checks (e.g., is text height positive?) after the glyph is
	loaded.
	(FT_Select_Size, FT_Request_Size): Scales are set to wrong values.
	Be careful that scales won't be negative.

	matching for requests of type NOMINAL and REAL_DIM.

	* src/winfonts/winfnt.c (FNT_Face_Init): Print trace message when
	`pixel_height' is used for nominal height.

	* src/base/ftobjs.c (FT_Request_Size): Call `FT_Match_Size' if the
	face is bitmap only and driver doesn't provide `request_size'.  This
	is added merely for completion as no driver satisfies the conditions.

	Introduce new size selection interface.

	* include/freetype/internal/ftdriver.h (struct FT_Driver_ClassRec):

	FT_Size_Request, FT_Request_Size, FT_Select_Size), src/base/ftobjs.c
	(FT_Select_Size, FT_Request_Size): API additions to export the new
	size selection interface.

	* include/freetype/internal/ftobjs.h (FT_Match_Size),
	src/base/ftobjs.c (FT_Match_Size): New function to match a size
	request against `available_sizes'.  Drivers supporting bitmap strikes
	can use this function to implement `request_size'.

	src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/type1/t1driver.c,

	Jumbo patch to fix `deprecated' warning of cross-build for Tiger on
	Intel, as reported by Sean McBride <[e-mail]> on
	2005-08-24.

	* src/base/ftmac.c: Heavy change to build without deprecated Carbon
	functions on Tiger.

	* builds/unix/configure.ac: Add options and autochecks for Carbon
	functions availabilities, for MacOS X.

	* builds/mac/ascii2mpw.py: Add converter for character `\305'.
	* builds/mac/FreeType.m68k_{far|cfm}.make.txt: Add conditional
	macros to avoid unavailable functions.
	ftmac.c must be compiled without `-strict ansi', because it disables
	cpp macro to use ToolBox system call.

	* builds/mac/FreeType.ppc_{classic|carbon}.make.txt: Add conditional
	macros to avoid unavailable functions.

	* builds/mac/README: Detailed notes on function availabilities.

	* docs/CHANGES: Notes about (possible) incompatibilities.

2006-01-08  Werner Lemberg  <[e-mail]>

	* docs/CHANGES: Updated.

2006-01-08  Huw D M Davies  <[e-mail]>

	* include/freetype/ftmodapi.h (FT_Module_Get_Flags): New
	declaration.

	* src/base/ftobjs.c (FT_Module_Get_Flags): New function.

2006-01-07  Werner Lemberg  <[e-mail]>

	* src/pcf/pcfread.c (pcf_get_bitmaps): Remove unused variable
	`bitmaps'.  Reported by Yu Lei <[e-mail]>.

	* src/base/ftutil.c (ft_highpow2): s/FT_BASE/FT_BASE_DEF/.
	Reported by Niels Boldt <[e-mail]>.

2005-12-28  suzuki toshiya  <[e-mail]>

	* src/sfnt/sfnt/ttbdf.c: Add newline '\n' to the end of file, for
	MPW compiler.

2005-12-23  David Turner  <[e-mail]>

	* Jamfile (RefDoc), docs/reference/README: Fix it so that `jam
	refdoc' works correctly to generate the API reference in
	`docs/reference'.

	* src/tools/docmaker/tohtml.py (print_html_field,
	print_html_field_list): Update to output nicer fields lists in the
	API reference.

	* src/base/ftobjs.c (FT_Load_Glyph): FT_LOAD_TARGET_LIGHT now
	forces auto-hinting.

	* freetype/freetype.h: Updating the documentation for
	FT_LOAD_TARGET_XXX and FT_Render_Mode values.

2005-12-23  suzuki toshiya  <[e-mail]>

	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Count scalable faces
	in supported formats (sfnt, LWFN) only, and ignore bitmap faces in
	unsupported formats (fbit, NFNT).  The number of available faces are
	passed via face->num_faces.  If bitmap faces are embedded in sfnt
	resource, face->num_fixed_size is correctly set.  In public API,
	FT_New_Face() and FT_New_Face_From_FSSpec() count the faces as
	FT_GetFile_From_Mac_Name(), which ignores NFNT resources.

	* doc/CHANGES: Mention the changes.

2005-12-17  Chia-I Wu  <[e-mail]>

	* src/truetype/ttinterp.c (Update_Max): Set current size of buffer
	correctly (so that memory debug system won't panic).

2005-12-16  Chia-I Wu  <[e-mail]>

	* include/freetype/internal/ftobjs.h (ft_glyphslot_grid_fit_metrics),
	src/base/ftobjs.c (ft_glyphslot_grid_fit_metrics): Removed.

	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Do not round.

	* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
	(cid_slot_load_glyph), src/truetype/ttgload.c (compute_glyph_metrics),
	src/type1/t1gload.c (T1_Load_Glyph): Do not round glyph metrics.

	* doc/CHANGES: Mention the changes.

2005-12-13  David Turner  <[e-mail]>

	Change the implementation of the LIGHT hinting mode to completely
	disable horizontal hinting.  This is an experimental effort to
	integrate David Chester's latest patch without affecting the other
	hinting modes as well.

	Note that this doesn't force auto-hinting for all fonts, however.

	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set
	scaler_fiags here but...
	(af_glyph_hints_rescale): Here.

	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal
	hinting for `light' hinting mode.


	* Jamfile: Small fix to ensure that ftexport.sym is placed into the
	same location as other generated objects (i.e., within the `objs'
	directory of the current directory).


	Add support for an embedded `BDF ' table within SFNT-based bitmap
	font files.  This is used to store atoms & properties from the
	original BDF fonts that were used to generate the font file.

	The feature is controlled by TT_CONFIG_OPTION_BDF within
	`ftoption.h' and is used to implement FT_Get_BDF_Property for these
	font files.

	At the moment, this is still experimental, the BDF table format
	isn't cast into stone yet.

	* include/freetype/config/ftoption.h (TT_CONFIG_OPTION_BDF): New
	macro.

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

	* include/freetype/internal/tttypes.h (TT_BDFRec, TT_BDF)
	[TT_CONFIG_OPTION_BDF]: New structure.
	(TT_FaceRec) [TT_CONFIG_OPTION_BDF]: New member `bdf'.

	* include/freetype/ttags.h (TTAG_BDF): New macro.

	* src/sfnt/Jamfile (_sources):
