I look forward to GTK2 for a number of reasons. :)

Yeah, I now update no more than 30fps, no matter how often it gets
requested, and _render_to_ only the 'changed' area, and it seems to be a
little better.

Still, how do video-playback programs achieve such low CPU usage (lower
than this little program) when displaying 24-30 fps 16:9 video? And
quake when doing 80fps? Is it an XVideo thing? If so... how could I use
that with pixbufs? :)
