Ideally, `trak` table value should be applied to glyph advances reported. This is what CoreText, hb-ot, and hb-ft do.

Research direction

Start by locating the skrifa glyph-advance reporting path and compare its behavior with CoreText, hb-ot, and hb-ft. The work is done when the `trak` table value is applied to the reported glyph advances consistently with those implementations.
