Does anybody know of any references to in-place zoom algorithms?
That is, methods for zooming a picture up or down in resolution with
overlapping source and destination windows, that doesn't step on itself
(suffer from feedback).  Doing it right, especially with filtering, is
a fun problem.  Has anybody seen or heard of algorithms like this before?

I just wrote such a beastie and I'm curious how novel it is.
