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.

I'm not sure why I put that limit in in the first place. I can't find
that limit in either the C Freetype code or the TTF spec.

Fix bug where the String representation of a Fix32 representing minus
one quarter was "0:064" instead of "-0:064".

A freetype.Context now has dst and src image setters and the notion of
a current point, instead of having to pass a painter and pt to DrawText.

This bug was introduced when an image.RGBA's representation went from
slice of slices to one linear buffer.

just version 2. The FTL (Freetype Licence) is still available. This
matches the original Freetype library (written in C).
This only expands and does not further restrict the licensing options
available to users of the freetype-go library.

It still isn't perfect (e.g. it doesn't join), but it's getting closer.
Also fix the bug where RotateCW and RotateCCW was mixed up, since the
Y-axis grows down in a computer graphics co-ordinate system, not up as
in classical mathematics.

Parsing a malformed TTF may result in an index out-of-bounds panic,
rather than guaranteeing to return an error. This may be tightened
in the future.
