Exactly and I've already written such 2d-compositing macros, that are pixel
accurate and can be used to blend images in various ways (overlay, screen,
etc like a paintprogram). The reason I did this, is because POV gives me
*much* more 2d-animation flexibility than any paintprogram I can think of...
I will post the macros on "povray.binaries.scene-files" in case anyone is
interested.

Regarding the motion blur - well - it will be time consuming to render the
extra amount of frames. You'd need at least 2 times more, and for fast
movements maybe 3 or more.
