BTW if you (or anyone else) are willing to make a variant that supports 
vista buffers (i.e. does not shear the camera but rotates it) that would 
surely be useful.  This will not generate a real zoomin of the main 
image then then of course.

Well surely you just set your camera's look_at to the object in question and
decrease the field of view angle?
Or would it be more complex than that?

The interesting thing is that, since the zoomed image is equivalent to a
subarea of the original image, there's no reason (as far as I can tell) that
vista buffers couldn't be used for it. It might be a bit harder to calculate
them, but it seems that as long as the right and up vectors are
perpendicular, it's possible.

  This would not produce a pure portion of the original image because the
perspective would change. OTOH, I'm not sure it matters that much. :)

A: Can anybody draw a rectangle, but with rounded edges?

B: Here you go!

C: That's not a rectangle! It has rounded edges! But maybe it doesn't
matter.
