18c06e189b [Indic] Add Uniscribe bug feature for dotted circle 
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC.  Which also is the only possible
sequence with 25CC at the end.

3bf27a9f0e [Indic] Disable conjuncts when a ZWJ happens 
Not that the code makes any difference since the presence of ZWJ itself
causes the ligature to fail to match anyway.

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.

daf3234bdc [Indic] Don't clear the mask for Reph

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!
