I wasn't able to look at the videos (missing plugins), but I don't
think that these are impossible per-se. If the videos are showing
windows resizing the content, then we need an XComposite patch create
temporary large pixmaps (or at least a pixmap of a new size) and
resize the window inside of that pixmap. This massively increases
binding speed on the nvidia driver and others.

Otherwise it is possible to do in-compiz by copying the old window
texture into temp memory, and stretching the old texture, fading it
out and fading through the new texture.
