aeacc15839 If recursed lookups may have non-1to1 lookups go into chaos mode 
We don't know what may happen, so don't narrow down glyphset
based on fixed-position assumptions.

This corrects flaw introduced in previous commit.  All good now.

849d25c95d Improve subsetting of Context formats 
When recursing for closure, just pass down glyphs that could have
actually matched the rule.

This can result in wrong results if the recursed lookup is NOT
one-to-one.  Fix coming.

In the mean time, test with NotoSansDevanagari-Bold.ttf and
chars uni91f,uni94d,uni930 to see the difference.

1d4fa13b4b When closing over GSUB narrow down the set for current glyph 
This allows partial closing of recursed lookups.

Test with updated Win8 calibrili and glyphs for text "dan".

1437426d69 When subsetting GSUB drop rules generating glyphs we don't want 
Right now this is unused since we always fully close over any
lookup.  But as we want to move to selectively NOT close parts
of lookups, this will be needed.

4cf7a80fa1 Implement Glyph.getComponentsFast() that works without loading glyph 
We still end up loading glyphs if pruning hinting.  And even if
we don't do that, rebuilding the maxp table loads all glyphs.
Working on those.
