Behdad Esfahbod 993c51915f Add fast-path to GSUB to check coverage
Shaves a good 10% off DejaVu Sans with simple Latin text for me.
Now, DejaVu is very ChainContext-intensive, but it's also a very
popular font!

Behdad Esfahbod 7b84c536c1 In MarkBase attachment, only attach to first of a MultipleSubst sequence
This is apparently what Uniscribe does.  Test case is:

  SEEN FATHA TEH ALEF

with Arabic Typesetting.  Originally reported by Khaled Hosny.

Behdad Esfahbod dbffa4c83d Fix Uniscribe charset matching
Previously was failing to match fonts that didn't support CHARSET_ANSI.

There still remains a problem with the Uniscribe backend, in that if a
font with the same family name is installed, and is newer, the native
one is preferred over the font we provide.  Fixing it requires rewriting
the name table with a unique family name...
