Use typographic font metrics when the font requests.

FreeType always returns the 'hhea' font metrics for ascent and descent,
and ignores the 'OS/2'::fsSelection::UseTypoMetrics bit. (It also
ignores the VDMX table, which makes this change correct.) This change
uses the typographic font metrics when the font requests their use.
