Possible to have a window "fizzle"?

[Pembar]

Hey guys,

I've been playing around with the animation library and I was wondering if it was possible to have a window "fizzle" into the background, as opposed to just hiding it.

By "fizzle", I mean, scattered pixels of the childwindow disappearing showing the background slowly.

Regards,

This is something that is handled by the window manager and not the application. You can emulate it but the effect will be far from perfect.
