Wireframe and Vertex modes back

Added the wireframe and vertex modes back to the render pipeline.

Also went back to 13 pixel lookups in the NFAA shader but with additional improvements i had with 8 lookups. The reason i went back was because 8 pixel lookups ignored some conditions…

Here’s a screen of the render/debug modes:

I will introduce 2 additional modes to output the geometry of lights and octrees.
