Chromatic shift based on distance from edge of screen.

Note for self. I remember seeing this in Bloodborne's post processing there is a very slight chromatic shift the closer an object is to the edge of the screen while objects in center of the screen are normal. Nice effect for some kinds of games. Should play and take notes on any apparent post processing effects which change deeper into game you get.

Effect is similar to this https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/SceneFringe/index.html

Could probably use cubic lens distortion for the chromatic aberration effect.
