How is it possible to get access to the windows that are on a given screen?

I have gotten the WorkBench screen via the GetScreenData() call and I can draw
into its bit-planes but it doesn't do me a lot of good (basically folks, it
trashes the screen).  After watching the mess that this produces I suddenly
realized that I don't want to write directly into the screen...  I want to
write into the backdrop window that the WorkBench puts back there.  Then a
call to RemakeDisplay() should end up with everything looking hunky-dory and
I'll be a happy camper.

So, what I need to know is how to find this backdrop windows bit-planes.  Help,
if you can and maybe we'll have another nifty screen hack before long.
