lesson to you: unit tests are good.

that anything outside the dirty rectangle is guaranteed to be unchanged, but
we currently mark far too many cells as dirty. This must be optimised.

Dirty rectangles are an upcoming optimisation that will tell the output
drivers which portion of the canvas has been really modified since the
last blit.
