Depixelate

Implementation of various scaling/depixelating techbologies.

This is very rough software that I threw together for my own amusement.
Feel free to modify it and make it better.

Currently it makes use of NSImage, so it only runs on Mac. It shouldn't be too hard to modify it to use jpeg and png libs directly, thus making it portable to other systems.
