i think your best bet is going to be keeping track of this externally. you can subclass the 'blit' and 'fill' methods from Surface. as for any of the other drawing functions, i'd say you'll just need an external function people must call to 'update' areas of your destination manually.

since they would probably want to do keep track of the 'dirty' areas anyways if it was a software display surface, it doesn't seem too painful to ask for the same information for your surface also.
