Eric Muller 30d7c40f8c Add a flag to hb_buffer_t to prevent the insertion of dotted circles on incorrect character sequences.
Current behavior unchanged if this flag is not set (and it isn't by default).

Ebrahim Byagowi e412008599 Remove redundant void from C++ sources (#1486) 2018-12-17 13:01:01 -05:00
Behdad Esfahbod 000d4b128e Make shaper's override_features() override user features as well
The override_features is used to override features that are normally
discretionary features, but in a specific shaper are for various
reasons desired to be bolted on or off, because they've been used
for inherent shaping.  As such, it makes sense that they also
override user features.  Ie. if user turned 'liga' on, we don't
want Khmer shaping to become broken...  Or turn 'clig' off...

Behdad Esfahbod 748962264a [aat] Disable mark advance zeroing if kern table has state-machines
Geeza Pro for example, relies on that for fancy mark positioning.

Behdad Esfahbod 62890dee18 [aat] Zero mark advances if decided so even if there's cross-kerning
Cross-kerning can only take care of positioning vertically.  It doesn't
adjust mark advance...

Behdad Esfahbod a201fa74cd [aat] Tweak fallback positioning logic when applying morx
Such that for Indic-like scripts (eg. Khmer), we don't do any fallback mark
advance-zeroing / positioning, but we do for Latin, etc.  Reuses preferences
of our script-specific OpenType shapers for those.

Fixes regression: https://github.com/harfbuzz/harfbuzz/issues/1393

Behdad Esfahbod f521a28b4a Embed hb_ot_shape_plan_t into hb_shape_plan_t
No other shaper will need shape_plan_data, by definition.  So, remove
abstraction layer and always create hb_ot_shape_plan_t as part of
hb_shape_plan_t.

Behdad Esfahbod 385f78b312 [aat] Remove deleted-glyhs after applying kerx/kern
Finally:  Fixes https://github.com/harfbuzz/harfbuzz/issues/1356

Test case:
$ ./hb-shape GeezaPro.ttc -u U+0628,U+064A,U+064E,U+0651,U+0629
[u0629.final.tehMarbuta=4+713|u064e_u0651.shaddaFatha=1@0,-200+0|u064a.medial.yeh=1+656|u0628.initial.beh=0+656]

The mark positioning (kern table CrossStream kerning) only works if deleted
glyph (as result of ligation) is still in stream and pushed through the
state machine.
