The latter sounds closer to what I'd like to do (the function is a messy
function from X,Y to X0,Y0), but I don't see how to get pixel data in and out
of an Image (aside from saving it to a file). I've read the doc, but maybe I
missed it. How can I just manipulate pixel values directly, one by one?
