NSCompositingOperation at a Glance

While Apple's documentation on NSCompositingOperation describes in detail what each compositing operation does, I've always had problems finding the right one. Today I broke down and just wrote a little NSView subclass that draws an example of all compositing operations. Feel free to download this image and print it out or whatever for future reference.
