Behdad Esfahbod 269de14dda Don't compose Hangul jamo
See thread "an issue regarding discrepancy between Korean and Unicode
standards" on the mailing list for the rationale.  In short: Uniscribe
doesn't, so fonts are designed to work without it.

but only if under MINGW32, so it doesn't affect MSVC.

Behdad Esfahbod f368ba4a9e [Arabic] Zero marks by GDEF, not Unicode category
Testing shows that this is closer to what Uniscribe does.

Reported by Khaled Hosny:

"""
commit 568000274c
...
This commit is causing a regression with Amiri, the string “هَٰذ” with
Uniscribe and HarfBuzz before this commit, gives:

	[uni0630.fina=3+965|uni0670.medi=0+600|uni064E=0@-256,0+0|uni0647.init=0+926]

But now it gives:

	[uni0630.fina=3+965|uni0670.medi=0+0|uni064E=0@-256,0+0|uni0647.init=0+926]

i.e. uni0670.medi is zeroed though it has a base glyph GDEF class.
"""

The test case is U+0647,U+064E,U+0670,U+0630 with Amiri.

Behdad Esfahbod a8cf7b43fa [Indic] Futher adjust ZWJ handling in Indic-like shapers
After the Ngapi hackfest work, we were assuming that fonts
won't use presentation features to choose specific forms
(eg. conjuncts).  As such, we were using auto-joiner behavior
for such features.  It proved to be troublesome as many fonts
used presentation forms ('pres') for example to form conjuncts,
which need to be disabled when a ZWJ is inserted.

Two examples:

	U+0D2F,U+200D,U+0D4D,U+0D2F with kartika.ttf
	U+0995,U+09CD,U+200D,U+09B7 with vrinda.ttf

What we do now is to never do magic to ZWJ during GSUB's main input
match for Indic-style shapers.  Note that backtrack/lookahead are still
matched liberally, as is GPOS.  This seems to be an acceptable
compromise.

As to the bug that initially started this work, that one needs to
be fixed differently:

Behdad Esfahbod 392ee97431 [ft] Remove TODO item re FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH
That flag is redundant, deprecated, and ignored since April 2011.
From FreeType git log:

commit 8c82ec5b17d0cfc9b0876a2d848acc207a62a25a
Author: Behdad Esfahbod <behdad@behdad.org>
Date:   Thu Apr 21 08:21:37 2011 +0200

    Always ignore global advance.

    This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
    deprecated, and ignored.  The new behavior is what every major user
    of FreeType has been requesting.  Global advance is broken in many
    CJK fonts.  Just ignoring it by default makes most sense.

    * src/truetype/ttdriver.c (tt_get_advances),
    src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
    tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
    src/truetype/ttgload.h: Implement it.

    * docs/CHANGES: Updated.

Behdad Esfahbod 2761e8a632 [win32] Remove MemoryBarrier() fallback implementation
I added these because the older mingw32 toolchain didn't have
MemoryBarrier().  The newer mingw-w64 toolchain however has.
As reported by John Emmas this was causing build failure with
MSVC (on glib) because of inline issues.  But that reminded me
that we may be taking this path even if the system implements
MemoryBarrier as a function, which is a waste.  So, just remove
it.

Behdad Esfahbod 94789fd601 [Indic] Sort pre-base reordering consonants with post-forms
Before, we were marking them as below-form for initial reordering.
However, there is a rule that says "post consonants should follow
below consonsnts" for base determination purposes.  Malayalam has
port-form YA/VA, and RA is pre-base.  As such, for a sequence like
YA,Virama,YA,Virama,RA, the correct base is at index 0.  But
because the code was seeing RA as a below-base, it was stopping at
the second YA as base, instead of jumping it as a post-base.

By treating prebase-reordering consonants like post-forms, this
is fixed.
