"Change Set: AlternativeDamageRecord Date: 23 December 2000 Author: Daniel Vainsencher
Uses alternative heuristic for recording damage - for any new damage (that isn't completely contained by the old damage), compare the costs of drawing it and each existing rect to the cost of drawing them merged. If a merge with any is cheaper, merge them, and run the same test on the new area. The approximation of costs use shoud handle many cases well that previously required special attention. Test with bouncing atoms, see them cluster."!
