Exactly. The dirtying of tiles should probably propagate an event to
listeners, (mainly the map rendering listener) so that they can re-render.

You might be right. As long as we can find a generic higher-level way to tie
events to certain map tiles. It's handy to be able to place a "quicksand" tile
and then get a callback when units enter it, for instance.
