Here's YET ANOTHER way to do this.  You can judge if it is less or more 
terrible than those already suggested.  I call it about even, but the one 
effect that it relies on IS documented.

I place it behind the WDEF approach, and ahead of hitting fields
in the WMgrPort in the cleaniness rankings.

a) Open a port (PORT, not window) in the location where the window will 
be. 
b) Fill port with black
c) Dispose of port.
d) Slam low memory PaintWhite ($9DC) to be zero (this keeps the window 
manager from filling the window with white, but leaves what is behind it, 
ie black), save the old copy.
e) Open your window, which will get the black area, and will NOT be filled 
with white.
f) Restore PaintWhite.
