Un-Ra U+09F1. According to the test suite this is correct.
...
But I'm not sure... Down from 54 failures to 52.

[Indic] For old-style Indic tables, move Halant around
...
In old-style Indic OT standards, the post-base Halants are moved after
their base. Emulate that by moving first post-base Halant to
post-last-consonant.
Brings test-shape-complex failures down from 88 to 54. Getting there!

[test] Fix problem with N'ko test direction

0x14db, direction expected glyphstring for N'ko. Doh!
Failures down from 92 to 88.

[Indic] Reorder matras

Next: Add Ra handling and it's fair to say we kinda support Indic :).

[Indic] Apply Indic features
...
Find the base consonant and apply basic Indic features accordingly.
Nothing complete, but does something for now. Specifically:
no Ra handling right now, and no ZWJ/ZWNJ.
Number of failing shape-complex tests goes from 174 down to 125.
Next: reorder matras.

Start cleaning up buffer var allocation
...
I've messed up a lot of stuff recently, different parts of the
shaping process are stumbling on eachother's toes because
manually tracking what's in which buffer var is hard. I'm
going to add some internal API to track those such that mistakes
are discovered as soon as they are introduced.
