Behdad Esfahbod 02b2922fbf [Indic] Towards better Reph positioning
Fixed for Deva cases with two full-form consonants.  Failures **way** down.
Not much left to go :-).

Behdad Esfahbod 74e54cf446 [Indic] Add Ra back for scripts without Reph
We now check that the 'rphp' table exists before forming Reph, so
we don't need to comment out Ra for those scripts.

Behdad Esfahbod 21d2803133 [Indic] Do clustering like Uniscribe does
Hindi Wikipedia failures down to 6639 (0.938381%)!

Behdad Esfahbod b20c9ebaf5 [Indic] Add test for matra group
The spec says: "[{M}+[N]+[H]]", and that's what Uniscribe implements.
We instead do: "{M+[N]+[H]}", which means we allow Nukta and Halant
after all Matras, not just the last one.  It makes more sense.

Behdad Esfahbod 8df5636968 [Indic] Reorder Reph to before the Halant after Matras
Uniscribe doesn't do it, but we want to do as it gives the Reph the
opportunity to interact with the Matras.  Test with mangal for example.
Sequence: <0930,094d,0915,094b,094d>
In test suite already.

Behdad Esfahbod daf3234bdc [Indic] Don't clear the mask for Reph
This was removing the mandatory global 1 bit in the mask and hence
disabling GPOS for Reph!

Behdad Esfahbod 7708ee23cb [Indic] Improve Left Matra repositioning
Move its dependents too.

Behdad Esfahbod 61a58e26a5 [Indic] Add tricky reordering test cases
In the case of Consonant,LeftMatra,Halant, Uniscribe leaves the Halant
where it is, but we want to move it with the Matra as that makes more
logical sense.

Behdad Esfahbod dbb105883c [Indic] Do Reph repositioning in final reordering like the spec says
This introduced a failure, which we tracked down to a test case like this:

  U+092E,U+094B,U+094D,U+0930

The final character is a Ra that should be put in a syllable of it's
own.  And we do.  But it will interact with the Halant before it.  So
now we finally are convinced that we have to limit features to syllable
boundaries.  That's coming after lunch!
