I am working on a CAD package in which I was hoping to have one window with
3 different clipping regions.  When I used InstallClipRect() (or whatever
it is called!), the rendering was noticably slower than when I have 3
separate windows.  I never looked into it further, but was always puzzled.
Any clues to this mystery, as well as the answer to Robin's question?
