Behdad Esfahbod af1aa362ca If HAVE_ICU_BUILTIN is defined, use hb-icu Unicode callbacks
Useful for Android / Chrome / etc when ICU is built in the same
library as harfbuzz itself.

Behdad Esfahbod a82165248c Only do fallback Hebrew composition if no GPOS 'mark' available
Apparently some modern fonts have proper GPOS mark positioning
tables, but undesirable precomposed forms!  See thread
"Hebrew composition to presentation forms" and:

Konstantin Ritt c9522de233 Make it possible to disable the fallback shaper at configure time
The OT shaper supersedes the fallback shaper in every case
and the latter become an extra weight for 99.9% of users.

Behdad Esfahbod ae23c24c32 [arabic] Disable 'cswh' by default
I believe Windows 8 disables it, and spec update dated
Jan 2014 also clearly says it's disabled by default:

Behdad Esfahbod c98b7183f7 [ot] Add Hangul shaper
Not exhaustively tested, but I think I got the intended logic
right.

The logic can perhaps be simplified.  Maybe we should disabled
normalization with this shaper.  Then again, for now focusing on
correctness.

Behdad Esfahbod 76fff252a9 Don't form fractions if only one of numr/dnom exist 2013-12-22 17:55:59 -05:00
Behdad Esfahbod 3aeee519f0 Bug 72698 - Automatically support frac / numr / dnom
When seeing U+2044 FRACTION SLASH in the text, find decimal
digits (Unicode General Category Decimal_Number) around it,
and mark the pre-slash digits with 'numr' feature, the post-slash
digits with 'dnom' feature, and the whole sequence with 'frac'
feature.

This beautifully renders fractions with major Windows fonts,
and any other font that implements those features (numr/dnom is
enough for most fonts.)

Not the fastest way to do this, but good enough for a start.
