Sorry for the noise, downstream custom builders. Please adjust.
2018-07-31[khmer] Rewrite most of shaper to better follow specBehdad Esfahbod1-1/+3
Khmer spec has only one reordering phase, and only simple prebase matra and Coeng-Ro reordering. Implement that. Specifically, this was done to address recognizing different orders of the matra and Coeng-Ro sequence. That said, some combinations are now reordered differently from Uniscribe. Not clear if that's intended or a bug in Uniscribe. The following two sequences render the same in Uniscribe whereas we reorder them differently: U+17A0,U+17D2,U+179A,U+17C2 U+17A0,U+17C2,U+17D2,U+179A For that reason, our test suite numbers regressed slightly. Used to be at 34 for fails, now at: KHMER: 299080 out of 299124 tests passed. 44 failed (0.0147096%) But generally a good change, and removed lots of code.

Seems to be working just fine!
2013-10-16[indic] Misc harmless fixes!Behdad Esfahbod1-1/+1
First, we were abusing OT_VD instead of OT_A. Fix that but moving OT_A in the grammar where it belongs (which is different from what the spec says). Also, only allow medial consonants after all other consonants. This doesn't affect any current character. Finally, fix Halant attachment in presence of medial consonants. Again, this currently doesn't affect any sequence. I lied. There's Gurmukhi U+0A75 which is Consonant_Medial. Uniscribe allows one of those in each of these positions: before matras, after matras and before syllable modifiers, and after syllable modifiers! We currently just allow unlimited numbers of it, before matras.
2013-10-15[indic] Handle AvagrahaBehdad Esfahbod1-2/+3
It can come either at the end(ish!) of the syllable, or independently. When independent, it accepts a few bits and pieces.

2012-08-31[Indic] Implement dotted-circle insertion for broken clustersBehdad Esfahbod1-1/+1
No panic, we reeally insert dotted circle when it's absolutely broken. Fixes most of the dotted-circle cases against Uniscribe. (for Devanagari fixes 80% of them, for Khmer 70%; the rest look like Uniscribe being really bogus...) I had to make a decision. Apparently Uniscribe adds one dotted circle to each broken character. I tried that, but that goes wrong easily with split matras. So I made it add only one dotted circle to an entire broken syllable tail. As in: "if there was a dotted circle here, this would have formed a correct cluster." That works better for split stuff, and I like it more.

It's a visual Repha. Still not positioning logical Repha as occurs in Malayalam. Another 200 Khmer failures fixed. 547 to go. That's better than Devanagari!

Down another 500 or so Khmer failures!
2012-07-17[Indic] Position final subjoined consonants (and vowels) after matrasBehdad Esfahbod1-0/+1
In Khmer, a final subjoined consonant or independent vowel can occur after matras. This final subjoined thing should NOT be reordered to before the matra even though it's subjoined. Fixes another 1k of the Khmer failures. Not much left really.
