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.
