Well #2 is vital to me - the VMS software involved expects to be able to turn 
on and off and change colours of 'overlays' (implemented as one or more planes) 
such as a background raster image while keeping foreground vector map visible 
and doing dynamic temporary stuff in a 'refresh mode' plane.
