This is in anticipation of removing the Point type entirely. Instead, we will
use the fixed.Point26_6 type from golang.org/x/image/math/fixed.

We use git and github now, not hg and code.google.com.

Fixes issue 16.

The logic is a little clunky, but as before, let's get it right first,
then get it clean once we have a full battery of tests.

Pass all the hinting tests. Hooray! Removing the hintingBrokenAt field
will be a follow-up CL.

The very subtle pp1x versus phantomPoints[0].X distinction is pretty
ugly code, but let's get all the tests passing first, so that we can
refactor with confidence.

Successfully hint all of DejaVu Sans Oblique, barring 4 exceptions
that are errors in the upstream C Freetype project. See

Also make print-glyph-points require Freetype version >= 2.5, which is
the latest version, at the time of writing.
