29c473cb3e freetype-go: Fix panic when drawing a span to the right of the
bounding rect.

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

2af394dab9 freetype: clarify that the GPL licence is "version 2 or later", not
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.

c95fb230fe freetype/raster: improve the stroking algorithm.
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.

future change once the API is agreed upon.

8552c06628 Freetype-Go: Paint now takes an explicit done bool instead of using a
magic zero value to indicate end of painting.

This means that Painter implementations can assume thant the Spans' Y
values are monotonic.

f6caa104ec Freetype-Go: truetype parser initial check-in.
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.
