Diffuse 02 - Point Cloud Octree Raytracing

Diffuse pass, 1 directional light.
1) Octree partition artifact: overlap points duplicated across octree partitions to remove holes.
2) Redundant points from different leaves: fixed to avoid shading an overlap point twice.
3) Some backface and frontface fixes (a bit hacky), so the far frontface gets occluded by near frontface, regardless how large a leaf is.
4) Smooth Silhouette: removes the "disk" look.

High % of extra overlap points makes storage inefficient. Previous papers cite 3x-8x increase.
