[mapguide-internals] Selection is slower than expected

When selecting items in map, a full new map image is generated.
This requires rendereing the entire map, and then transfering the entire 
map to the client.

Has anyone tried to implement the selection as a transparent png, 
containing only the selected graphics (overlay image)?
This procedure is potentially very fast to render, and certainly has a 
much smaller size.

Are there any issues that would obstruct such an implementation?
