5e85cd59ab Added support for occluders occluding other occluders, which helps reduce
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.

a node contains occluders before traversing.

occluder in the view frustum, to be used as pre cull traversal.
