Comment (by chrisclaydon):

 I don't think the approach of just bundling up wheel events is going to
 feel right to the end user - each time you roll the mouse wheel through a
 detent, the map view should zoom in or out, but without actually re-
 rendering the image (just re-scaling or moving it). The idea is to give an
 idea of where you're zooming to. If you're zooming in, the displayed map
 will become blurred, and if you're zooming out, it will no longer fill the
 screen. That doesn't matter since it's just providing context until the
 full re-draw occurs when you stop moving the wheel.
