MiRCART.py:MiRCARTCanvas.canvasBitmap: added to optimise onPaint(). 

MiRCART.py:MiRCARTCanvas._onMouseEvent(): additionally draw to canvasBitmap via temporary wx.MemoryDC().
MiRCART.py:MiRCARTCanvas.onPaint(): reimplement using (double-buffered) wx.BufferedPaintDC() from canvasBitmap.
MiRCART.py:MiRCARTCanvas.__init__(): initialise canvasBitmap from canvas window size.
