commit 0c1b287b72e91e0898d75acb5d5acf1c6b9a7498
Author: Ebrahim Byagowi <ebra...@gnu.org>
Date: Sat Jul 21 21:14:48 2018 +0430
Add a new API, hb_ot_layout_get_feature_name_ids (#976)
This new API returns cvXX and ssXX related NameId, things like
featUiLabelNameId, featUiTooltipTextNameId, sampleTextNameId, ... of cvXX
and UINameId of ssXX, in a unified way.
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.

Remove dump-fon (#1100)
It had interesting stuffs like EXE parsing and
big-endian parsers but added in an attempt to find
a solution for #681 which later found not related.
