Manually Mask Rounded iPhone Icons for Stacks/Categories

I'm writing this post because I was not able to find anything remotely close to solving this problem elsewhere.

The goal (for me, but there are other uses): custom theme stacks icons so that dock reflections work properly. There are more reasons to do this though, such as making icons display correctly in categories. You could also use this to fix jailbroken apps which don't have nice iPhone style icons.
