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 1082338525 [shape-plan] Only use shape-plan key to initialize hb_ot_shape_plan_t

Behdad Esfahbod 3e284e02c2 [shape-plan] Minor 2018-11-11 22:51:34 -05:00
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 ca23567f41 Disable fallback mark positioning if kern table has cross-stream kerning
Happens even if the cross-stream kerning is for cursive attachment only.  Oh well..

Behdad Esfahbod 5b563640b2 Remove HB_DISALLOW_COPY_AND_ASSIGN from hb_ot_shape_planner_t
It was arbitrary that this struct had it and not dozens of others.

Behdad Esfahbod ffe3478448 [aat] Allow enabling/disabling features
Only works at entire-buffer range, not sub-ranges.

Test with:

$ hb-shape Zapfino.dfont Zapfino
[Z_a_p_f_i_n_o=0+2333]

$ hb-shape Zapfino.dfont Zapfino --features=-dlig
[Z=0+416|a=1@-21,0+264|p_f=2+433|i=4+181|n=5+261|o=6+250]

$ hb-shape Zapfino.dfont Zapfino --features=+dlig
[Z_a_p_f_i_n_o=0+2333]
