Hi,

I've not much experience with this, but did you thought of OpenGL
(gtkglext)? I think this should be fast enough. If you are flexible,
perhaps try the upcoming EFL (www.enlightenment.org) from CVS. This has
nothing todo with gtk, but the apps on top this library have *very fast*
graphic effects like you need.
