A first pass at this is now in CVS.
The "clearmask N" message can be passed to a gemwin to set the clearing
behaviour. "N" is simply cached and passed directly in the glClear call -
generate it using the GLdefine mechanism and GL_COLOR_BUFFER_BIT,
[GEMglClear] can be used in other gemlists to control buffer clearing.
