   You can also with a little more difficulty write straight
to the window..  Below is a fragment from __init__ of a
wx.Frame descendant.  (It's straight from working code but I
haven't tested it independently.)


        w, h = self.GetClientSizeTuple()
        bmp = wx.EmptyBitmap (w, h)
        mdc = wx.MemoryDC()
        if bmp.LoadFile ("sweeper.bmp", wx.BITMAP_TYPE_BMP):
            mdc.SelectObject (bmp)
            wx.ClientDC (self).Blit (0,0, w,h, mdc, 0,0)


   The complication with such techniques is that you need to
coordinate a lot of different objects..  Frame, Bitmap, DC..
and look up the separate documentation on those guys.. to
get any work done.  Also not shown is the paint routine that
replays that Blit operation after an EVT_PAINT.  Just for
what it's worth because I was just working on this.
