Map View "Pan and Zoom" undo/redo

If you change the map zoom by scrolling in or out, using the magnifying glass buttons to zoom inor out, or using the zoom rectangle button, the View Menu undo and redo selections become active allowing you to undo or redo each zoom level. For example, if you use the mouse scroll wheel to zoom in three times, you can then undo three times back to your original zoom level.
