cellrendererpixbuf: Put pixbufs into textures

... instead of going via surfaces.

A side effect is that the pixbuf property is no longer readable because
we have no good way to get the pixbuf back out of the texture, but I
don't think this matters a lot.

If people want to read the pixbuf property, we need to add some code to
make that work.
