Right. That seems pretty reasonable.

I guess I was hoping libart could be used for most of this, at least
until code to use XRender is written (I'm pretty sure XRender supports
transforms).

I might write some code in this direction, at the very least it might be
usefull for when this actually goes into gdk.
