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!

8613193bbf [test] Fix problem with N'ko test direction 
Old HarfBuzz test suite always shaped as left-to-right and hence had wrong
0x14db, direction expected glyphstring for N'ko.  Doh!

Failures down from 92 to 88.

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.

651e8dd79e 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.

18c42850c9 Shrink space used for ligature ids 
This frees 16bits in the glyph_info struct during the ot_layout process.
We can use the freed space in the shapers now.

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.

aa7264123a Only form clusters if we are reversing 
This produces more accurate cluster mappings.  Cluster mappings are
minimal now.  Combining marks get their own cluster value most of
the time.
