290cef39be [glyf] When instancing, just spew empty VarComposites 
Before we were dropping the entire glyf table.

000a3c5dca [beyond-64k/subset] Fetch lsb from glyph table if not available 
The beyond-64k hmtx table doesn't encode LSB. If subsetting brings
the glyph under 64k (which currently is the only mode we support),
then we need to encode the LSB, which wasn't available. We need to
fetch xMin from glyf table and set it as LSB.
