Garret Rieger bc06af977f [subset] speed up feature collection when tags are specified. 
Precompute a feature index filter to avoid needing to iterate the feature tag list for each encountered feature index. For this particular fuzzer case speeds up feature collection from 50s to 2s.

Behdad Esfahbod 93e6a9bc4e Revert "Remove unneeded buffer clear_output / remove_output calls" 
This reverts commit 06175b7143.

One of the sanitizers is failing. Pushing again as PR to debug.
I have suspicions.

Behdad Esfahbod 06175b7143 Remove unneeded buffer clear_output / remove_output calls 
Made sure clear_output is always paired with swap_buffers.
Trying to see if we can move towards RAII-like buffer iterators
instead of the buffer keeping an iterator internally.

Ebrahim Byagowi 122a2897e4 [aat] Remove lcar support 
Very low use, only two distinct font files, Apple Chancery.ttf and Hoefler Text.ttc
have it so it really doesn't worth the size addition and so, but one may argue that
whole ligature caret is low use but guess we better to encourage GDEF one anyway.

Ebrahim Byagowi d38eb49f46 Move the iteration logic to FeatureParamsCharacterVariants 
Hopefully I can make members protected also.
 2020-06-19 23:46:49 +04:30
Ebrahim Byagowi 9b3d4f457e Use dagger in hb_ot_layout_feature_get_characters 
The way it used to work was a bit nonidiomatic but the replacment
is idiomatic way of iterating used elsewhere.

The new code just doesn't check nullability of "characters", which isn't
what we do anywhere else.

Ebrahim Byagowi f1488152bd [doc] Remove the not needed comment 
All the other similar iterating API are like this and don't have such
comment, written at the time I wasn't familiar enough with the way such
API are shaped.

Behdad Esfahbod b2a1acccd9 Simplify get_glyph_alternates() dispatcher 
Trying to make it **very simple** to add a specialized dispatcher for
one API to be routed to just a few objects (one in this case).
 2020-06-18 16:41:31 -07:00
Behdad Esfahbod ffe8d3f39d Use dispatch for get_glyph_alternates_t 
First time we do this in a way that if target object doesn't have the matching
function we basically "ignore".  Risky but I feel like is the right decision
for this case.

I'm going to put back the template varargs and use those, which would make
the dispatcher be just that: "dispatcher", and wouldn't need to carry the
call context.  That would be a refreshing change I think.
