Porter-Duff composition operator used. This saves a malloc when passing
an AlphaSrcPainter as a value of Painter interface type.

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.

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
