Michiharu Ariza db0d83ddc7 Merge branch 'master' into cff-subset 2018-10-13 17:25:38 -07:00
Michiharu Ariza 9228db06f4 added CFF1 Expert Encoding subset test & bug fixes 2018-10-13 17:25:09 -07:00
Ebrahim Byagowi dc49bd8d81 Add two APIs for getting stylistic set labels
* hb_ot_layout_feature_get_characters
* hb_ot_layout_feature_get_name_ids

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.
