If someone could write that program and test whether the scaled versions
were correct (by comparing it to some know values) as well, it would
help me a lot in improving the patch I sent to for
integer pixops. I can program well enough, but I'm really new to image
processing and don't have as much time between my fledgling consultancy
and other things I have to do to learn the details.

Speaking of profiling, are there any preferences to how we go about
doing performance tests? I've used oprofile and papi before when I did
embedded work.
