I believe (although I could be wrong) all that happened with regard to
gtk3 is that wxDC == wxGCDC which draws on the advanced
wxGraphicsContext object which AFAIK supports transparency so XOR
drawing should not be an issue.  The perform issue can probably solved
by drawing to a wxMemoryDC first and blitting it to the display.
