[Thai] Adjust SARA AM reordering to match Uniscribe Adjust the list of marks before SARA AM that get the reordering treatment. Also adjust cluster formation to match Uniscribe. With Wikipedia test data, now I see: - For Thai, with the Angsana New font from Win7, I see 54 failures out of over 4M tests (0.00129107%). Of the 54, two are legitimate reordering issues (fix coming soon), and the other 52 are simply Uniscribe using a zero-width space char instead of an unknown character for missing glyphs. No idea why. The missing-glyph sequences include one that is a Thai character followed by an Arabic Sokun. Someone confused it with Nikhahit I assume! - For Lao, with the Dokchampa font from Win7, 33 tests fail out of 54k (0.0615167%). All seem to be insignificant mark positioning with two marks on a base. Have to investigate.
