Looks like just an application bug. I don't see any problem in cairo
itself.

I've just committed a fix to gameoflife to help it clean up after
itself better. It's not as efficient as it could be, but it should
give correct results now.

Thank you. As for a "cairo based gtk+" you hardly need wait. In CVS,
the cairo-demo/gtk directory shows you how to draw your own widgets
using cairo. And the cairo-gtk-engine directory gives you a way to
make Gtk+ use cairo for drawing all of its core widgets.

I can't imagine that there is a lot still missing for a cairo based
gtk+.
