        * include/freetype/cache/ftcglyph.h, src/cache/ftcglyph.c:
        fixed a dangling pointer bug that happened in very rare cases:
        i.e. when a new family object was destroyed by an out-of-memory
        condition during a glyph node initialization. The function
        FTC_Cache_Lookup would flush the cache and restart the lookup
        with a bad pointer.

        * src/cache/ftcmanag.c: fixed a cache flushing bug

        * src/truetype/ttinterp.c (TT_Normalize): fixed a bug that
        caused long and unecessary delays when normalizing huge vectors

2004-07-15  Werner Lemberg  <wl@gnu.org>

	* docs/CHANGES: Updated.

	* src/base/ftstroke.c (FT_Stroker_ParseOutline): Fix compiler
	warning.

2004-07-15  David Turner  <david@freetype.org>

	* src/base/ftstroke.c (FT_Stroker_ParseOutline): Single points
	are not stroked, preventing a bug with pala.ttf and other
	fonts.

	* include/freetype/ftstroke.h: Updating documentation comments.

2004-07-13  Werner Lemberg  <wl@gnu.org>

	* src/base/ftstroke.c (ft_stroke_border_reverse): Removed.  Unused.

2004-07-12  David Turner  <david@freetype.org>

	* src/base/ftstroke.c (ft_stroke_border_close): Add second parameter
	to indicate reversion of points.
	Update all callers.
	(ft_stroke_border_reverse): Fix initialization of `point1' and
	`tag1'.

	* src/cache/ftcsbits.c (ftc_snode_load): Fixing advance computation
	for transformed glyphs.

2004-07-11  David Turner  <david@freetype.org>

	Fix bugs that prevented the stroker to correctly generate stroked
	paths from closed paths, i.e., nearly all glyphs in vectorial fonts.

	The code is still _very_ buggy though; treat with special care.

	* src/base/ftstroke.c (FT_STROKE_TAG_BEGIN_END): New macro.
	(ft_stroke_border_reverse): New function.
	(ft_stroker_inside): Remove local variable `sigma'; use different
	threshold.
	(ft_stroker_add_reverse_left): Switch begin/end tags if necessary.
	(FT_Stroker_EndSubPath): Call ft_stroker_inside and
	ft_stroke_border_reverse.

2004-06-26  Peter Kovar  <peter.kovar@r3.roburnet.sk>

	* src/truetype/ttgload.c (load_truetype_glyph): Fix typo.

2004-06-25  Werner Lemberg  <wl@gnu.org>

	* src/type1/t1afm.c (afm_atoindex): Fix boundary test.  Reported
	by Dirck Blaskey.

2004-06-24  David Turner  <david@freetype.org>

	* src/truetype/ttgload.c, src/truetype/ttxgvar.c: Removing
	compiler warnings.

2004-06-23  Werner Lemberg  <wl@gnu.org>

	* include/freetype/internal/ftmemory.h [FT_DEBUG_MEMORY]: Declare
	FT_QAlloc_Debug and FT_QRealloc_Debug.

	* src/base/ftutil.c (FT_QAlloc): Fix error and debug messages.
	(FT_QRealloc): Call FT_QAlloc if original pointer is NULL.
	Fix error message.

2004-06-23  David Turner  <david@freetype.org>

	* include/freetype/internal/ftmemory.h, src/base/ftutil.c
	(FT_QAlloc, FT_QRealloc), src/base/ftdbgmem.c (FT_QAlloc_Debug,
	FT_QRealloc_Debug): New functions that perform allocation without
	zero-ing out the corresponding blocks.

	* include/freetype/internal/ftmemory.h (FT_MEM_QALLOC,
	FT_MEM_QREALLOC, FT_MEM_QNEW, FT_MEM_QNEW_ARRAY,
	FT_MEM_QRENEW_ARRAY, FT_QALLOC, FT_QREALLOC, FT_QNEW, FT_QNEW_ARRAY,
	FT_QRENEW_ARRAY): New macros.

	* src/base/ftstream.c (FT_Stream_EnterFrame): Use FT_QALLOC.
	* src/gzip/ftgzip.c (FT_Stream_OpenGzip):  Use FT_QNEW_ARRAY.
	* src/sfnt/sfobjs.c (tt_face_get_name): Use FT_QNEW_ARRAY.

	* src/sfnt/ttload.c (tt_face_load_directory, tt_face_load_metrics,
	tt_face_load_gasp): Use FT_QNEW_ARRAY.
	(tt_face_load_kern): Use FT_QNEW_ARRAY.
	Small optimization in the kerning table verifier; this speeds up
	TrueType face opening by about 7%.
	(tt_face_load_hdmx): Use FT_QNEW_ARRAY and FT_QALLOC.

	* include/freetype/config/ftmodule.h: Changed the order of modules,
	putting TrueType and Type 1 first.  This dramatically improves the
	performance of face open/close operations.  For example, putting the
	TrueType driver first in the list results in a 5x speedup when
	opening `Vera.ttf'.

	The very problem is that both the PCF and BDF drivers do a lot more
	than necessary to detect that they cannot handle a font file.

2004-06-22  Werner Lemberg  <wl@gnu.org>

	* src/pcf/pcfread.c (pcf_read_TOC, pcf_get_properties,
	pcf_get_metrics, pcf_get_bitmaps, pcf_get_encodings): Improve
	debugging messages.

	* src/pcf/pcfdrivr.c (FT_COMPOMENT): Move up.
	(PCF_Face_Init): Simplify code.

	* src/bdf/bdfdrivr.h (BDF_FaceRec): New element `default_glyph'.

	* src/bdf/bdflib.c (_bdf_add_property, _bdf_parse_start),
	src/bdf/bdf.h (bdf_font_t): s/default_glyph/default_char/.

	* src/bdf/bdfdrivr.c (BDF_Face_Init): Fix number of glyphs.
	Set `default_glyph'.
	(BDF_Glyph_Load): Use `default_glyph' for undefined glyph.

	* docs/CHANGES: Updated.

2004-06-21  Werner Lemberg  <wl@gnu.org>

	* docs/CHANGES: Updated.

2004-06-21  David Turner  <david@freetype.org>

	* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
	load_truetype_glyph): Don't access (unrounded)
	`TT_Size.root.metrics' but (rounded) `TT_Size.metrics'.  This fixes
	a scaling bug that caused incorrect rendering when the bytecode
	interpreter was enabled.

2004-06-14  Huw D M Davies  <h.davies1@physics.ox.ac.uk>

	* src/winfonts/winfnt.c (FNT_Face_Init): Set x_ppem and y_ppem
	based on pixel_width and pixel_height.
	(FNT_Size_Set_Pixels): Updated.

2004-06-14  Werner Lemberg  <wl@gnu.org>

	* src/lzw/zopen.c: Comment out inclusion of signal.h and unistd.h.
