here flickering is bad on certain machines, certain not. I think it 
could be related on which acceleration X11 supports, but that's a guess.
- iBook/ATI video, acceleration disabled due to bugs. Debian/ppc/cario : 
flickering extremely bad, toolbar flicker without resizing
- Gentoo/x86/art on ATI video: flickering is bad but less noticeable 
because it is on "grey" and not "on black"
- FreeBSD/x86/cairo on intel video: no flickering, very smooth!
- Debian/x86/xlib on VirtualBOX: moderate flickering (but way better 
than before)

On NetBSD/x86/cairo with ATI I can't get a live resize: the window does 
not update (it just clips) until I release the mouse.

On all setups I use WindowMaker with live-resize enabled, of course.

I'd say this patch makes things worse except on some systems where 
instead it works perfectly.
