Werner Lemberg a8772918a3 [autofit] Minor fix.
* src/autofit/afcjk.c (af_cjk_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Fix handling
of alternative standard characters.

Werner Lemberg a336400112 [autofit] Introduce two more slots for standard characters.
This is useful for OpenType features like `c2sc' (caps to small
caps) that don't have lowercase letters by definition, or other
features that mainly operate on numerals.

* src/autofit/afscript.h: Add more standard characters.

* src/autofit/aftypes.h: Update use of `SCRIPT' macro.
(AF_ScriptClassRec): Add members to hold two more standard
characters.
(AF_DEFINE_SCRIPT_CLASS): Updated.

* src/autofit/afglobal.c, src/autofit/afglobal.h,
* src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/hbshim.c:
Update use of `SCRIPT' macro.

* src/autofit/afcjk.c (af_cjk_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Scan two more
standard characters.

Werner Lemberg 72f5ff5bbb [autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy.  It defines `writing systems' which can contain multiple

able to support scripts like Latin, Cyrillic, Armenian, etc., which
can be handled similarly.

Scripts are now named using four-letter OpenType tags.

to...

sample glyphs.  At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default.  For detail, see

af_script_classes array initialization was moved to afpic.c and
is later refered using macros defeined in afpic.h.

New Files:
* src/autofit/afpic.h declare struct to hold PIC globals for autofit
module and macros to access them.
* src/autofit/afpic.c implement functions to allocate, destroy and
initialize PIC globals for autofit module.

David Turner 281679de85 * include/freetype/internal/tttypes.h, src/autofit/afangles.c,
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
        src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.
