Could be useful to use use of max/min as constraints instead of guaranteeing that some type of resize will happen.

Seems like it'd be useful be to able to limit any image's size if and only if it exceeds the maximums. (I don't think that this is supported, at least)

E.g. if you have an image that's 50x73 pixels, and you use maximums of 800x600, then it would simply return once it determined that resizing wasn't needed.

simple to add as a wrapper function, of course, but I just figured I'd mention it.
