Post Process Shaders

In computer graphics, a post process shader is what really amps up a final render's last details. It can also change the entire scene into a drastically different color style. (Did you know Borderlands had a realistic art style until they slapped a more cartoony shader on everything and thought it fit better?)

I would like to see some default shaders of various types that apply to the final output image - and maybe even an ability to use custom ones made by users!

Note that this can partially be done image editing, but you can get some really neat effects having access to things like the normals of the 3d models in relation to the viewing camera for outlines, and more complicated effects. Only DA is in a position to provide that.
