image contrast and brightness

[Ben Fisher]

I think someone was wondering how to do Contrast and Brightness effects on images... Anyways I made a little stack to do this and other effects. It's actually pretty fast without using any externals. Please check it out and give me some feedback.

Right now the code may be hard to understand. I'll update it soon with better comments.
