-/* miHandleExposures
- generate a region for exposures for areas that were copied from obscured or
-non-existent areas to non-obscured areas of the destination. Paint the
-background for the region, if the destination is a window.
-
-NOTE:
- this should generally be called, even if graphicsExposures is false,
-because this is where bits get recovered from backing store.
-
-NOTE:
- added argument 'plane' is used to indicate how exposures from backing
-store should be accomplished. If plane is 0 (i.e. no bit plane), CopyArea
-should be used, else a CopyPlane of the indicated plane will be used. The
-exposing is done by the backing store's GraphicsExpose function, of course.
