Comment:

 Submission 1659 doesn't really solve the problem. It zooms by the same
 factor, regardless of the amount the wheel has moved. A solid solution
 would also need to adjust the zoom of the current map image on the fly, so
 that the user has an idea of where they're zooming, but delay the request
 for an updated map image at the necessary scale and resolution until the
 zooming is done. It's hard to describe in words, but the MG AJAX viewer
 does a reasonable job of implementing it.
