I am writing an application and it renders polygons to
NSGraphicsContext (graphics context with bitmap image rep)
between each drawing however I would like to clear the bitmap image
rep and draw on a blank bitmap.
At the moment the previous image is still in the bit map and should
not be there.
So.. How do I clear the bitmap?
Or is there a bit blit mode like xor that I can use? (Does that make
any sence?)
