Wu, Chia-I (吳佳一) 4cdb45c01e Introduce experimental autofit CJK module based on akito's autohint
patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
Add CJK module based on akito's autohint patch.

* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
overlap length of the segments.  (AF_SEGMENT_LEN, AF_SEGMENT_DIST):
New macros.

* src/autofit/aflatin.h (af_latin_metrics_init_widths),
src/autofit/aflatin.c (af_latin_metrics_init_widths): Made `FT_LOCAL'.
Use the character given by the caller.
(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
the thresholds.

* src/autofit/afloader.c (af_loader_load_g): Respect
AF_SCALER_FLAG_NO_ADVANCE.

src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c:

    adding experimental implementation of "warp hinting" (new hinting
    algorithm for gray-level and LCD rendering). It is disabled by default,
    you need to #define AF_USE_WARPER in aftypes.h to enable it.

  a 'kern' table.

David Turner e664efaddd * src/autofit/*: important fixes to the auto-fitter. The output
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

* src/autohint/ahhint.c (ah_hinter_load): Handle two more points.
* src/truetype/ttgload.c (Get_VMetrics): New function.
(TT_Load_Simple_Glyph, TT_Process_Simple_Glyph): Handle two more
points.
(load_truetype_glyph): Use Get_VMetrics.
Handle two more points.
(compute_glyph_metrics): Thanks to vertical phantom points we now
can always compute `advance_height' and `top_bearing'.
* src/truetype/ttobjs.h (TT_SubglyphRec): Add vertical phantom
points.


* src/autohint/ahglyph.c (ah_outline_load): Fix allocation of
`news'.

Converting some files to Unix end-of-line convention.

        could crashed the font engine when a cached service pointer was
        retrieved with FT_FACE_LOOKUP_SERVICE
