Bounce squares around the screen, doing the re-drawing in the background back-buffer.
Double buffering is usually required. It is most useful when you have a complex drawing routine
that you want to quickly 'flip to' without being able to see the frame being drawn.
Double buffering is not usually required. It is only useful when you have a long (in duration)
drawing routine that you want to 'flip to' once complete without the drawing being visible to
the naked eye when looking at the HUB75 panel.
Please note that double buffering isn't a silver bullet, and may still result in flickering
if you end up 'flipping' the buffer quicker than the physical HUB75 refresh output rate.
