freetype:字库引擎,执行程序,用于安装 2.3.5

	This caused problem when displaying on non-square surfaces.

	* src/pshinter/pshalgo2.c: s/vertical/dimension/.

	* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
	point constant with a fixed-float equivalent.  For some reasons not
	all compilers are capable of directly computing a floating pointer
	constant casted to FT_Fixed, and will link a math library instead.

	tracing strings.

	* src/cache/ftcmanag.c (ftc_family_table_alloc,
	ftc_family_table_free, FTC_Manager_Check): Ditto.
	* src/cache/ftcsbits.c (ftc_sbit_node_load): Ditto.

	* src/base/ftobjs.c (FT_Done_Library): Remove compiler warning.

2001-12-19  David Turner  <[e-mail]>

	* include/freetype/cache/ftcache.h: Added comments to indicate that
	some of the exported functions should only be used by applications
	that need to implement custom cache types.

	* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug
	that prevented composites from loading correctly, due to missing

	(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):
	`Fixed' the bug that prevented embedded bitmaps to be loaded when
	the auto-hinter is used.  This actually is a hack but will be enough
	until the internal re-design scheduled for FreeType 2.1.

	* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline
	shifting bug in the monochrome renderer.

	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Remove compiler warning.
	* include/freetype/ftcache.h (FTC_Node_Unref): Removed.  It is
	already in ftcmanag.h.

2001-12-14  Sam Latinga  <[e-mail]>

	* builds/mac/freetype.make: A new Makefile to build with MPW on
	MacOS classic.

2001-12-14  David Turner  <[e-mail]>

	(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),
	src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to
	all font drivers (the advance width was never hinted when it
	should).

	* include/freetype/freetype.h (FREETYPE_PATCH): New macro.
	* src/base/ftdbgmem.c (debug_mem_dummy) [!FT_DEBUG_MEMORY]: Don't
	use `extern' keyword.

2001-12-12  David Turner  <[e-mail]>

	* src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem
	psh_globals_new): Adding correct BlueScale/BlueShift support, plus
	family blues processing.

2001-12-12  Werner Lemberg  <[e-mail]>

	* builds/unix/freetype2.m4: Some portability fixes.

2001-12-11  Jouk Jansen  <[e-mail]>

	* src/sfnt/ttload.c (TT_Load_Generic_Header): Typos.

2001-12-11  David Turner  <[e-mail]>

	* builds/unix/freetype-config.in: Modified the script to prevent
	passing `-L/usr/lib' to gcc.

	* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').

	* builds/unix/freetype2.m4: New file for checking configure paths.
	We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I
	didn't modify builds/unix/install.mk yet.

	* INSTALL: Updated the instructions to build shared libraries with
	Jam.  They were simply wrong.

	* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused
	slightly improper results for `FT_Cos' and `FT_Sin' (example:
	FT_Sin(0) == -1!).

2001-12-11  Detlef Würkner  <[e-mail]>

	* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):

2001-12-06  Leonard Rosenthol  <[e-mail]>

	Added support for reading .dfont files on Mac OS X.  Also added a
	new routine which looks up a given font by name in the Mac OS and
	returns the disk file where it resides.

	* src/base/ftmac.c: Include <Files.h> and <TextUtils.h>.
	(is_dfont): New auxiliary function.
	(FT_New_Face_From_dfont): New function.

2001-12-06  Werner Lemberg  <[e-mail]>

	* INSTALL: Small update.

2001-12-05  David Turner  <[e-mail]>

	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Re-ordered code for
	debugging purposes.
	Comment out use of `origin'.

	* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug
	where outline shifting wasn't correctly undone after bitmap
	rasterization.  This created problems with certain glyphs (like '"'
	of certain fonts) and the cache system.

	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.
	* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.

2001-12-05  David Turner  <[e-mail]>

	* src/pshinter/pshalgo2.c (psh2_hint_table_init),
	src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler
	warnings.

	* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:
	Yet another massive rewrite of the caching sub-system in order to
	both increase performance and allow simpler cache sub-classing.  As
	an example, the code for the image and sbit caches is now much
	simpler.

	I still need to update the documentation in
	www/freetype2/docs/cache.html to reflect the new design though.

	* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
	macro.
	(FT_CACHE_INTERNAL_CACHE_H): Updated.

2001-12-05  David Krause  <[e-mail]>

	* docs/license.txt: s/X Windows/X Window System/.

2001-12-04  Werner Lemberg  <[e-mail]>

	* src/raster/ftraster.c: Fix definition condition of MEM_Set().
	* src/smooth/ftgrays.c (M_Y): Change value to 192.
	* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
	Remove unused variable.
	* src/cache/ftcimage.c (ftc_image_node_init,
	ftc_image_node_compare): Remove unused variables.
	* src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
	variable.
	* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
	compiler warning.
	* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
	avoid compiler warnings.
	* src/pcf/pcfread.c (tableNames): Use `const'.
	(pcf_read_TOC): Change counter name to avoid compiler warning.
	Use `const'.
	* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
	declaration.
	* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
	to avoid shadowing.
	* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.
	* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
	and `T1_Size_Done()'.

2001-11-20  Antoine Leca  <[e-mail]>

	* include/freetype/ttnameid.h: Added some new Microsoft language
	codes and LCIDs as found in MSDN (Passport SDK).  Also added
	comments about the meaning of bit 57 of the `OS/2' table
	(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is
	a character beyond 0xFFFF in this font'.  Thanks to Detlef Würkner
	<[e-mail]> for noticing this.

2001-11-20  David Turner  <[e-mail]>

	* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting
	routine that created nasty alignment artefacts.

	* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.

	* src/smooth/ftgrays.c: De-activated experimental gamma support.
	Apparently, `optimal' gamma tables depend on the monitor type,
	resolution and general karma, so it's better to compute them outside
	of the rasterizer itself.
	(gray_convert_glyph): Use `volatile' keyword.

2001-10-29  David Turner  <[e-mail]>

	Adding experimental `gamma' support.  This produces smoother glyphs
	at small sizes for very little cost.

	* src/smooth/ftgrays.c (grays_init_gamma): New function.
	(gray_raster_new): Use it.

	Various fixes to the auto-hinter.  They merely improve the output of
	sans-serif fonts.  Note that there are still problems with serifed
	fonts and composites (accented characters).

	* src/autohint/ahglyph.c (ah_outline_load,
	ah_outline_link_segments): Implement it.
	Fix typos.
	(ah_outline_save, ah_outline_compute_segments): Fix typos.
	* src/autohint/ahhint.c (ah_align_serif_edge): New argument
	`vertical'.  Implement improvement.
	(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
	Fix typos.
	(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
	typos.
	(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
	* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
	* src/autohint/ahtypes.h: Ditto.
	(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
	(making them global as `ah_debug_disable_horz' and
	`ah_debug_disable_vert').
	Fix typos.

	* tests/gview.c: Updated the debugging glyph viewer to show the
	hints generated by the `autohint' module.
