I meant the root window size vs. the screen pixmap size.  The driver is a
lot better about it than when I started at NVIDIA, so it may just work.  :)

I don't think we'll have any problems with the clip regions, that code is
pretty self-contained.  A quick grep shows that we don't use borderSize
anywhere, but we do use winSize for some obscure overlay colormap code
that's been around for ages.  We use borderClip and clipList all over the
place.
