Garret Rieger e583505334 [subset] Use plan->glyphset_gsub instead of plan->glyphset for GSUB/GPOS 
This matches fontTools behaviour. glyphset_gsub does not contain gids added from closing over composite glyphs in glyf, since these cannot particpate in GSUB/GPOS processing.

Looks like static methods that do not get inlined end up exported.

hides all inline methods.
