I *think*, and correct me if I'm wrong, the pre-win7 spec was 'mlym' and
the win-7 spec introduced 'mlm2'. I can't seem to find the supporting
documentation in microsoft opentype site though.

The problem is, there is already a 'pstf' table for 'Ra, Halant' (for mlym)
defined in Rachana and Meera, which is present for years and I know not why
(I thought only 'Halant+Ra' should make the 'Ra sign'). We tried adding
'pref' table also for the same sequence during the Pune language summit,
but then found that the 'Ra' rendering goes haywire with complex conjuncts
and to fix that a lot of combinations to be added in the font. :-/
