Also increase the maximum recursion depth from 4 to 8, since some
x-deja-vu-sans-oblique glyphs are actually depth 4. It's an arbitrary
limit. The C Freetype code doesn't seem to limit recursion (below
whatever the font says it needs), but it seems safer to have a limit.

Also add a test that freetype-go derives the same glyph points as
the C freetype implementation.

These new opcodes aren't unit-tested per se, but they will be
exercised by an end-to-end hinting test of the Luxi fonts.
