The most obvious, and by far most difficult route, would be to make graphics devices first class citizens (IIRC Duncan TL has brought this up elsewhere) wherein you would aDev <- edit(aDev). That brings things to the device level (what you want) and a static device could act accordingly (i.e. not invoke a redraw). Obviously the most difficult as it would be a massive upheaval of base graphics (I suppose all of this could all be grouped under a category of "event-based streams," graphics events, XML SAX events, file events--aka connections, etc. Doesn't CL or Scheme have something along those lines?). But, as mentioned in the thread, pretty speculative but you never can tell what someone might hunker down and implement :-)
