5e72071062 [Indic] Stop looking for base upon seeing joiners 
Not sure where this is documented, but I remember this being the desired
behavior.

test-shape-complex failures are down from 48 to 46.  Meh.

8354e004e5 Un-Ra U+09F1. According to the test suite this is correct. 
But I'm not sure...  Down from 54 failures to 52.

f5bc2725cb [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!

45d6f29f15 [Indic] Reorder matras 
Number of failing shape-complex tests goes from 125 down to 94.

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

743807a3ce [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.

02cdf743c2 Add prefer_decomposed() complex-shaper callback 
This allows the Indic shaper to request decomposed characters.  This will
handle split matra for free.  Other shapers prefer precomposed
characters.

f6fd3780e1 Let shapers decide when to apply ccmp and locl 
Instead of always applying those two features before the complex shaper,
let the complex shaper decide whether they should be applied first.

Also add stub for Indic's final_reordering().

b9ddbd5593 [Indic] Start an Indic shaper 
Nothing functional in there yet.

So far, we're parsing IndicSyllabicCategory.txt and IndicMatraCategory.txt
fils from Unicode Character Database and store them in an array to be used
by the shaper.  Also hooked up the shaper, but it does not do anything
right now.
