Behdad Esfahbod 044d7a06db [indic-like] Add per-lookup per-syllable flag 
This allows mix-and-matching per-syllable and other lookups.
In fact, removes the clear-syllables call completely.

Meson build writes to the source directory (issue #3507 ) (#3508)

Khaled Hosny f76ffa8374 [build] Change how platform shaper tests are enable 
Run the tests unconditionally and skip if the shaper is not available.
This fixes distcheck (https://github.com/harfbuzz/harfbuzz/pull/3504)
and shows SKIP for these tests instead of ignoring them.

Merge pull request #3504 from fanc999/dist-plat-shaper-tests 
test: Dist the platform shaper test data
 2022-03-24 05:51:22 +02:00
Chun-wei Fan eb44d64bc2 test: Dist the platform shaper test data 
For builds from release tarballs, the tests fail in the DirectWrite and
Uniscribe tests when these platform shapers are enabled, since the data files
were not found in the source tree, when building with Meson at least.

Fix this by dist'ing the platform shaper test data files.
