I'm too lazy to fix the tests now.

Mozilla Bug 669175 - Slow rendering of text sometimes in this case,
using direction: rtl

Still not much there.

They are outdated with respect to the DejaVu Sans I'm using.
We need to add font version checking to the tests.

One has to run the test with --verbose to see that right now.

Towards a better test runner.

We'd add normalization and decomposition tests later.

Needs fonts to be put in test/fonts.  Tests are skipped otherwise.
Run with --verbose for details.  Working on improving the test runner
to make it easier to make sense of what's going on.

Copied form HarfBuzz.old Indic data.  These are below and post
consonants.  This is temporary.  Read the comment in the patch.

Using an incredible tool called Ragel.

Matches OT types now.

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.

We apply all of vert, vrt2, vkrn, valt, and vpal.

Also change the Version type to avoid similar bugs in the future.

k is the index, not j.

Respectively, separate planner from the actual plan.
