c782f4976c Various minor PLBVH related changes. 
-Use most significant bit instead of negative for internal nodes.
-Explicitly store root node index, so that it does not have to be 0.
-Check the root node first in PLBVH traversal.
-Fix rigid body clipping in RaytracedShadowDemo.

3e8b183587 Avoid breaking up the clipHullHull kernel, it ruins performance. Unfortunately, Mac OSX still requires it. 
Use indices instead of copies for small/large aabbs in broadphase (grid / sap)

33ebebd1c9 allow PairBenchmark to select broadphase type, with cpu brute-force, gpu brute-force etc 
fix issue in PairBench, related to index offset
allow to add a large AABB in PairBench, to see the effect on the broadphase pair search performance
