Draw perspective text as paths.

Perspective glyphs can vary in screen size so it's unclear which SDF
level is best, and even if we choose one for an entire subrun it's
possible that a given glyph will have artifacts if it's too big.
Instead we fall back to paths unless specifically requested to
support perspective SDF.
