Really basic - reuse the image, and if the letter/colour is the same as previous, just don't redraw it.
Previously I thought about trying to shift everything off by one, but this should do at least 50% of that much more easily.
Of course somehow getting the pure delta and updating could be nice too, but it's too hard.
