Garret Rieger 463ae07e99 [subset] In the preprocess subset call always use long loca.
Long loca is needed so that we can store the trimmed glyph bytes to allow us to safely skip trimming in the later subset.

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
we need pass in source glyph's outline data to calculate boundaries, and
then drop the outline data if notdef-outline is specified.

Also disable shifting points for instancing in get_points () API

Qunxin Liu 58dbc00162 [instance] Fix compiling Composite glyph bytes
The x/y offset encoded with int8 originally might overflow after deltas
are applied. So we cannot just copy and update old values.
