And... that seems to be breaking rendering on Windows 7. Example - പ്ര
is rendered as പ്‌‌ര - Pa, Virama, separate Ra. Seems to be due to the
'half' forms; adding back the 'pres' rule for 'p1xx r1' does fix it.

I now have a version of Rachana which works great on Harfbuzz
(mlm2/mlym) and Windows XP SP3 (mlym) but doesn't work correctly on
Windows 7 - the only issue is Ra again, it seems to be expecting the
half forms for independent consonants. But for conjuncts, I'm clueless
- because ക്ത്ര is displayed as 'r4 k1th1' but ക്ത്രോ is correct! May
be complex interaction of 'pref/pres/psts' rules, dunno.
What would we want to do with Win 7?
