cc576f80	2016-12-20T11:37:42	[truetype] Fix linear metrics of GX variation fonts. When asking for an unhinted non-default variations, `linearVertAdvance' is currently the value from the `hmtx' table instead of the actual value after applying the variation. `HVAR' support fixes this, but fonts will exist without that table and will need sane fallback. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Implement linear advance adjustments if `HVAR' or `VVAR' tables are missing.
a1e85f11	2016-12-20T10:52:26	[cff, truetype] Fast advance width retrieval for fonts with HVAR.
