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).

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.

Y-axis grows down in a computer graphics co-ordinate system, not up as
in classical mathematics.
