The case it currently detects is optimized by drivers (because there is no
transform).

Whether or not the X server / driver interface should know when it can turn a
slow operation into a fast operation, there is always the risk that the
server's detection algorithm won't cover all the cases in cairo's "doesn't
matter" detection for its mis-optimization.</pre>
