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.

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

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

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.
