2006-03-20  David Turner  <[e-mail]>

	* include/freetype/cache/ftccache.h,
	include/freetype/cache/ftccmap.h, include/freetype/cache/ftcglyph.h
	include/freetype/cache/ftcimage.h include/freetype/cache/ftcmanag.h
	include/freetype/cache/ftcmru.h include/freetype/cache/ftcsbits.h:
	Move to...

	* src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h,
	src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h,
	src/cache/ftcmru.h: This new location.
	Update declarations according to the changes in the corresponding
	source files.

	Note that these files are not used by FreeType clients; all public
	APIs of the cache module have been already moved to
	`include/freetype/ftcache.h', and all FT_CACHE_INTERNAL_XXXX_H
	macros resolve to it.

	Reason for the move is to allow modifications of the internals
	without interferences with rogue clients.  Note that there are no
	known clients that access the cache internals at the moment.

	* builds/unix/install.mk (install): Don't install headers from
	$(CACHE_H).
	Remove `freetype/cache' from the target directory.

	* include/freetype/config/ftheader.h (FT_CACHE_MANAGER_H,
	FT_CACHE_INTERNAL_MRU_H, FT_CACHE_INTERNAL_MANAGER_H,
	FT_CACHE_INTERNAL_CACHE_H, FT_CACHE_INTERNAL_GLYPH_H,
	FT_CACHE_INTERNAL_IMAGE_H, FT_CACHE_INTERNAL_SBITS_H): Point to
	FT_CACHE_H.

	* src/cache/ftcbasic.c, src/cache/ftccache.h, src/cache/ftccback.h,
	src/cache/ftccmap.c, src/cache/ftcglyph.c, src/cache/ftcglyph.h,
	src/cache/ftcimage.c, src/cache/ftcimage.h, src/cache/ftcmanag.c,
	src/cache/ftcmanag.h, src/cache/ftcmru.h, src/cache/ftcsbits.c,
	src/cache/ftcsbits.h: Don't use the FT_CACHE_INTERNAL_XXX_H macros
	but include the headers directly (which are now in `src/cache').

	* src/cache/ftccache.c:  Don't use the FT_CACHE_INTERNAL_XXX_H
	macros but include the headers directly.
	(FTC_Cache_Init, FTC_Cache_Done, FTC_Cache_NewNode,
	FTC_Cache_Lookup, FTC_Cache_RemoveFaceID): Declare as FT_LOCAL_DEF.

	* src/cache/ftccache.c:  Don't use the FT_CACHE_INTERNAL_XXX_H
	macros but include the headers directly.
	(FTC_MruNode_Prepend, FTC_MruNode_Up, FTC_MruNode_Remove,
	FTC_MruList_Init, FTC_MruList_Reset, FTC_MruList_Done,
	FTC_MruList_New, FTC_MruList_Remove, FTC_MruList_RemoveSelection):
	Declare as FT_LOCAL_DEF.
	(FTC_MruListFind, FTC_MruList_Lookup) [!FTC_INLINE]: Compile
	conditionally.
	Declare as FT_LOCAL_DEF.


	* builds/win32/visualc/freetype.dsp: Update project file, add
	missing base source files (ftstroke.c, ftxf86.c, etc.).


	* src/autofit/afcjk.c, src/autofit/aflatin.c, src/base/ftobjs.c,
	src/cff/cffobjs.c, src/cid/cidobjs.c, src/pfr/pfrobjs.c,
	src/sfnt/sfobjs.c, src/sfnt/ttmtx.c, src/type1/t1afm.c,
	src/type1/t1objs.c: Remove compiler warnings when building with
	Visual C++ 6 and /W4.

	* src/autofit/aflatin.c (af_latin_hints_init): Disable horizontal
	hinting for italic/oblique fonts.



	* src/truetype/ttpload.c, src/truetype/ttpload.h
	(tt_face_get_device_metrics): Change second argument to `FT_UInt'.

2006-03-06  David Turner  <[e-mail]>

	* src/cache/ftcmanag.c (FTC_Manager_Lookup_Size): Prevent crashes in
	Mozilla/FireFox print preview in Ubuntu Hoary.

2006-02-28  Chia-I Wu  <[e-mail]>

	* src/base/ftutil.c (ft_mem_qalloc) [FT_STRICT_ALIASING]: Do not
	return error when size == 0.

2006-02-28  Chia-I Wu  <[e-mail]>

	* src/base/ftobjs.c (FT_Done_Library): Remove modules in reverse
	order so that type42 module is removed before truetype module.  This
	avoids double free in some occasions.

2006-02-28  David Turner  <[e-mail]>

	* Release candidate VER-2-2-0-RC4.

2006-02-27  Werner Lemberg  <[e-mail]>

	* include/freetype/cache/ftccache.h
	[FT_CONFIG_OPTION_OLD_INTERNALS]: Remove declaration of
	ftc_node_done.

	* src/cache/ftccache.c (ftc_node_destroy)
	[!FT_CONFIG_OPTION_OLD_INTERNALS]: Mark as FT_LOCAL_DEF.  This
	should now fix all possible compilation options.

2006-02-27  David Turner  <[e-mail]>

	* src/base/ftutil.c (ft_mem_alloc, ft_mem_qalloc, ft_mem_realloc,
	ft_mem_qrealloc): Return an error if a negative size is passed in
	parameters.

	* src/cache/ftccache.c (ftc_node_destroy): Mark as FT_BASE_DEF since
	it needs to be exported for rogue clients.

	* src/pshinter/pshglob.c (psh_blues_set_zones_0): Prevent problems
	with malformed fonts which have an odd number of blue values (these
	are broken according to the specs).

	* src/cff/cffload.c (cff_subfont_load), src/type1/t1load.c
	(T1_Open_Face): Modify the loaders to force even-ness of
	`num_blue_values'.

	(cff_index_access_element): Ignore invalid entries in index files.

2006-02-27  Chia-I Wu  <[e-mail]>

	* src/base/ftobjs.c (GRID_FIT_METRICS): New macro.
	(ft_glyphslot_grid_fit_metrics, FT_Load_Glyph) [GRID_FIT_METRICS]:
	Re-enable glyph metrics grid-fitting.  It is now done in the base
	layer.
	(FT_Set_Char_Size, FT_Set_Pixel_Sizes): Make sure the width and
	height are not too small or too large, just like we were doing in
	2.1.10.

	* src/autofit/afloader.c (af_loader_load_g): The vertical metrics
	are not scaled.

2006-02-26  Werner Lemberg  <[e-mail]>

	* docs/release: Minor additions and clarifications.

	* docs/CHANGES: Updated to reflect many fixes for backwards
	compatibility.  Still incomplete.

2006-02-26  David Turner  <[e-mail]>

	* src/base/ftobjs.c (ft_recompute_scaled_metrics): Re-enable
	conservative rounding of metrics to avoid breaking clients like
	Pango (see http://bugzilla.gnome.org/show_bug.cgi?id=327852).

2006-02-25  Werner Lemberg  <[e-mail]>

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

	src/psaux/afmparse.c,, src/psaux/t1cmap.c, src/smooth/ftgrays.c
	src/tools/apinames.c, src/truetype/ttdriver.c: Add various casts,
	initialize variables, and decorate functions with FT_CALLBACK_DEF,
	etc., to fix compiler warnings (and C++ compiling errors).

	* src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with
	gcc.

	* builds/unix/ftsystem.c: Don't include FT_INTERNAL_OBJECTS_H but
	FT_INTERNAL_STREAM_H.

	* src/base/ftsystem.c: Include FT_INTERNAL_STREAM_H.

2006-02-24  Chia-I Wu  <[e-mail]>

	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
	ft_contour_enclosed, ft_outline_get_orientation): Commented out.  We
	have to wait until `FT_GlyphSlot_Own_Bitmap' is stabilized.
	(FT_Outline_Embolden): Use `FT_Outline_Get_Orientation'.

2006-02-24  Chia-I Wu  <[e-mail]>

	* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update
	documentation.

	* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),

2006-02-24  David Turner  <[e-mail]>

	* Release candidate VER-2-2-0-RC3.
	----------------------------------

	* src/cache/ftcbasic.c: Correct compatibility hack bug.

2006-02-24  Chia-I Wu  <[e-mail]>

	* include/freetype/freetype.h (FT_Size_RequestRec): Change the type
	of `width' and `height' to `FT_Long'.
	(enum FT_Size_Request_Type), src/base/ftobjs.c (FT_Request_Metrics):
	New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales
	directly.

2006-02-23  David Turner  <[e-mail]>

	Two BDF patches from Debian libfreetype6 for 2.1.10.

	* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width
	glyphs.
	Fix a problem with large encodings.


	Fix binary compatibility issues for gnustep-back (GNUstep backend
	module) which still crashes under Sarge.

	* src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,
	FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
	structures and enumerations.
	(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
	compatibility code.

	* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to
	support rogue clients compiled against 2.1.7 to work correctly.
	This probably explains the GNUstep crashes with the second release
	candidate.

2006-02-23  Chia-I Wu  <[e-mail]>

	* include/freetype/ftoutln.h (enum FT_Orientation): New value
	`FT_ORIENTATION_NONE'.

	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
	ft_contour_enclosed, ft_outline_get_orientation): Another version of
	`FT_Outline_Get_Orientation'.  This version differs from the public
	one in that each part (contour not enclosed in another contour) of the
	outline is checked for orientation.
	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.
