I have an application that I am toying with that would like to use
three bitplanes, so that I can draw things on one bitplane without it
interfering with things drawn on other bitplanes.  The problem is how
do I do this on a 1-plane system?  I had originally hoped that
transparent windows would work, but upon closer reading of the manual
it became obvious that they wouldn't help.  Does anyone have any ideas
on how I can do this, or am I missing something obvious?

Thanks in advance,
Mike Shaddock
