Garret Rieger 8f1bf23cc9 [subset] optimize glyf subsetting w/ retain gids.
When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.

Qunxin Liu b90ce34a25 [instance] fix for non-empty .notdef glyph metrics update

Also disable shifting points for instancing in get_points () API
