d5c4edcdd6 [Indic] Apply presentation-forms features all at once 
Seems like this is what Uniscribe is doing, and does not break any fonts
we tested (with Devanagari, Malayalam, Khmer, and Bengali), while fixing
some Ra Phala sequences for Bengali with Vrinda.  Fixes another 2% of
Bengali failures (a couple more to go).

af92b4cc90 [Indic] Disable 'kern' in Uniscribe bug compatibility mode 
Uniscribe does not apply 'kern' in the Indic module.  Some of the Khmer
fonts they ship have small adjustments in the 'kern' table.  Disable
'kern' in the Indic module under Uniscribe bug compatibility mode.

Fixes some 10% of the Khmer failures.  Remains under 3% (excluding
dotted-circle ones).

df50b84740 [Indic] Categorize other Khmer marks 
Mark them the same as the Register Shifters for now.  Need to rename

Fixes another percent of Khmer failures.  Down to under 3%!

d487fff266 Split matras without a Unicode decomposition 
This is a hack for now, to get us going with Khmer.  This will be
refactored properly later to move the complex logic into complex
shapers.

8aa801a6fd [Indic] Adjust position for split matras 
We are going to split matras without a Unicode decompositions in a way
that the second half takes the codepoint of the whole matra.  So,
position them where the second half is supposed to end up.

2023e2b54d [ft] Disable ppem setting 
The calculations were wrong.

FreeType makes it really hard to set size and ppem independently.
For now, disable it.  Need to come up with a fix later.

552bf3a9f9 Bump WINNT version requested from 500 to 600 
Since we use the OpenType versions of Uniscribe functions, we are
relying on that version of the WINNT API.  Otherwise, usp10.h will hide
those symbols.
