bytecode interpreter. This is an experimental feature which
should probably be made optional.
* src/truetype/ttgload.c (TT_Process_Simple_Glyph,
load_truetype_glyph): Move the code to set the pedantic_hinting flag
to...
(TT_Load_Glyph): Here.
Set `grayscale' flag except for `FT_LOAD_TARGET_MONO'.
* src/truetyep/ttinterp.c (Ins_GETINFO): Return MS rasterizer
version 1.7.
Return rotation and stretching info only if glyph is rotated or
stretched, respectively.
Handle grayscale info.
* src/truetype/ttinterp.h (TT_ExecContextRec): Add `grayscale'
member.
FreeType now can read kerning values from PFM files.
* src/type1/t1afm.c (T1_Done_AFM): Renamed to...
(T1_Done_Metrics): This.
Update all callers.
(T1_Read_AFM): Make it static.
Don't enter and leave a frame.
(LITTLE_ENDIAN_USHORT, LITTLE_ENDIAN_UINT): New macros.
(T1_Read_PFM): New function.
(T1_Read_Metrics): New higher-level function to be used instead of
T1 Read_AFM.
Update all callers.
ppem values.
(PCF_Set_Point_Size): Don't call PCF_Set_Pixel_Size but provide own
code to compare ppem values.
* src/bdf/bdfdrivr.c (BDF_Set_Pixel_Size): Compare heights, not
ppem values.
(BDF_Set_Point_Size): Don't call BDF_Set_Pixel_Size but provide own
code to compare ppem values.
TT_NAME_ID_PREFERRED_FAMILY and TT_NAME_ID_PREFERRED_SUBFAMILY.
* src/cff/cffload.c (cff_font_load): Always create inverse mapping.
Even if the charstring count id different from the CID count, it is
still possible that the font uses a different CID -> GID mapping.
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
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.
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.

* include/freetype/internal/ftmemory.h, src/base/ftutil.c,
src/base/ftmemdbg.c: introducing the new FT_QAlloc and FT_QRealloc
functions that do perform allocation without zero-ing out the
corresponding blocks. Corresponding macros like FT_QALLOC, FT_QNEW,
etc.. have been defined too
* include/freetype/config/ftmodule.h: changed the order of modules
in order to _dramatically_ improve 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 problem is really that the PCF and/or BDF drivers are broken
and do a lot more than necessary simply to detect that they
cannot handle the font file.
* src/sfnt/ttload.c: small optimization in the kerning table
verifier, speeds up TrueType face opening by about 7%.
Also changed code to use the new FT_QNEW_ARRAY call when
appropriate to slightly improve performance.
* 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.
src/cache/ftccache.c, src/cache/ftcglyph.c, src/cache/ftcmanag.c,
src/cache/ftcsbits.c:
fixing some annoying bugs and inefficiencies in the cache sub-system.
src/autofit/afloader.c, src/autohint/ahhint.c:
moved the definition of 'lsb_delta' and 'rsb_delta' from FT_GlyphMetrics
to FT_GlyphSlotRec. The old location did BREAK BINARY COMPATIBILITY
of the library !!
* src/sfnt/sfobjs.c: removing compiler warning
Improve inter-letter spacing for autohinted glyphs.
* include/freetype/freetype.h (FT_Glyph_Metrics): Add elements
`lsb_delta' and `rsb_delta'.
* src/autohint/ahhint.c (ah_hinter_load): Set `lsb_delta' and
`rsb_delta' in slot->metrics.
now seems to be 100% equivalent to the auto-hinter, while being
about 2% faster (which proves that script-specific algorithm
selection isn't a performance problem).
to test it, change "autohint" to "autofit" in
<freetype/config/ftmodule.h> and recompile.
a few more testing is needed before making this the official
auto-hinting module
auxiliary functions.
(T1_Get_MM_Var): Provide axis tags.
Use mm_axis_unmap and mm_weights_unmap to provide default values
for design and normalized axis coordinates.
* include/freetype/t1tables.h (PS_DesignMapRec): Change type of
`design_points' to FT_Long.
Update all users.

prototypes given in header files from include/freetype/cache. Use
casts to proper types locally.
(ftc_cmap_cache_class): Remove casts.
* src/cache/ftcglyph.c (ftc_gnode_compare, ftc_gcache_init,
