Nice work as always Andrea. A one-liner wrapping the DC used for
drawing in a wxGCDC gives very nice anti-aliasing, but makes it quite
a bit slower. Maybe if I can find some time I'll work on a port that's
optimized for wxGraphicsContext. I think it could end up quite faster
than the raster based version.
