cae76d540a [glyf] Load using LazyDict 
Going to revert. No speedup since glyphs are loaded lazy
anyway.  And one test fails I have no idea why:

bcd5e4c216 Rip out glyf1 VarComposites 
In favor of separate VARC table.

ttGlyphSet does NOT yet know how to draw VARC table though.

The 9 failing tests are all VarComposite-related and need
to be updated with VARC equivalents eventually when we
add VARC support to subsetter and instancer.

* sstruct.getformat now returns dictionaries, merge them
