I spoke with Carl Worth (of cairo fame) at length and he offered an
alternative: we could implement an intelligent region selector to call
Render::render with. The playing field would get updated in only those
locations which have changed. For block moving, this would be the join
of the old and new location on the playing field. For deleting a line,
the entire field would be re-rendered. This would make the game
completely playable again.
