I am trying to do some simple double-buffering in an intuition window.
(rendering to an offscreen rastport and clipblitting to the displaying
window.) Predictably, I am getting some of the flashing. In this application
the flashing is quite disturbing. Is there a convenient way to get around that.

One is led to believe that performing a WaitBOVP() right before the ClipBlit 
would help to get rid it. But that doesn't seem to do a thing. What gives?
