The Normal Buffer Overlay Shader

Keith added a new shader that allows us to blend in a normal map into the background. The top left postage stamp shows the normal buffer blended in with the additional overlay map. This opens up the door to add a lot more character to the environment at minimal cost. 

So now we can add random cracks, water damage, bullet holes, and pretty much any surface detail without having to create entire new maps for each section.
