Arguments: region
Returns a box that indicates the smallest orthogonal rectangle that completely contains a hotspot region. region should be a value that is valid for hotspot-region.
This function could be useful for finding a box to invalidate to ensure that a hotspot is entirely redrawn (or undrawn). A shortcut for that is to simply call invalidate on the hotspot itself rather than on its parent window, but perhaps there are similar uses for region-box.
