I was just wondering if it is really unsupported or only unimplemented... In the cairo backend I could implement a different method that uses DSPD_ADD. Need to do some tests, however. > and allows anti-aliased edges with and without blending. I see that the driver enables blending internally when antialiasing is enabled.
