0164d934b6 [autofit] Introduce subscript top blue zones.
This feature is mainly for Khmer: The idea is to avoid a clash
between the top of subscript glyphs and the bottom of normal
baseline glyphs.

This only works for character clusters mapped to multiple glyphs.

* src/autofit/afblue.dat: Add subscript top blue zone for Khmer.

* src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New
macro.

* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

* src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE,
AF_LATIN_BLUE_SUB_TOP): New macros.

* src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new
blue zone property.
Update tracing messages.
(af_latin_metrics_scale_dim): Handle new blue zone property.
(af_latin_hints_compute_blue_edges): Updated.

facb79abdc [autofit] Add support for Khmer script.
We split Khmer into two auto-hinter scripts: `Khmer' (`khmr') and
`Khmer symbols' (`khms', U+19E0-U+19FF).

* src/autofit/afblue.dat: Add blue zone data for Khmer.

* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

24aa9c665e [autofit] Rewrite HarfBuzz interface to support character clusters.
Scripts like Khmer have blue zones that can't be directly
represented by Unicode characters.  Instead, it is necessary to let
HarfBuzz convert character clusters into proper glyph representation
forms, then deriving the blue zone information from the resulting
glyphs.

* src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by...
* src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new
files, providing a new API to access HarfBuzz.

The new API manages a HarfBuzz buffer with `af_shaper_buf_create'
and `af_shaper_buf_destroy'.  The buffer receives a UTF8 encoded
string with function `af_shaper_get_cluster', and the resulting
glyph data (indices, advance widths, vertical offsets) can be
iteratively accessed with function `af_shaper_get_elem'.

* src/autofit/afcjk.c (af_cjk_metrics_init_widths,
af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated.

* src/autofit/aflatin.c (af_latin_metrics_init_widths,
af_latin_metrics_init_blues, af_latin_metrics_check_digits):
Updated.

* include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/.

* src/autofit/afglobal.c: s/hbshim.h/afshaper.h/.
(af_face_globals_compute_style_coverage): Updated.

* src/autofit/afglocal.h: s/hbshim.h/afshaper.h/.

* src/autofit/autofit.c: s/hbshim.c/afshaper.c/.

f45c0bf963 [autofit] Use string of standard characters.
This is more flexible; additionally, it would allow character
clusters.

* src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated.
(AF_ScriptClassRec): Replace `standard_char[123]' with
`standard_charstring'.

* src/autofit/afscript.h: Replace last three character arguments
of the `SCRIPT' calls with a string parameter, holding the standard
characters (in UTF-8 encoding) separated with spaces.

* src/autofit/afglobal.c, src/autofit/afglobal.h,
src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c
