* 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.

Use mm_axis_unmap and mm_weights_unmap to provide default values

`design_points' to FT_Long.
Update all users.

(ftc_basic_image_family_class, ftc_basic_image_cache_class,
