Matplotlib doesn't use the wx.GCDC class. Eventually you do have to draw something to the screen, right? Is there another way to do that besides going through a DC? It doesn't seem possible to create a wx.GraphicsContext without providing a DC (at least in Python). In my testing, it seemed that clipping of any kind caused a major decrease in speed, not the kind of DC being used.
