The original DSI interface (sun.awt.DrawingSurface, etc.) has been superceded
by the new JAWT interface in kestrel. We decided to keep the old interface
around for one release; however, it should probably be removed for merlin.
Since the interface is not a public API, only customers who were specifically
notified about the interface should have ever used it. Those customers have
since been notified about the new interface.
