Cluster Visibility & Frustum Culling

[tominated]

In order to perform face visibility and frustum checks, I need to remove a bunch of optimizations. I need to once again store each face separately in order to render them selectively. I will need to use the BSP leaf nodes to perform the visibility set and frustum checks. I will be able to sort the faces that passed the check and group them by material and lightmap, then render in groups.
