PxFilterFlags PxDefaultSimulationFilterShader(PxFilterObjectAttributes attributes0, PxFilterData filterData0, PxFilterObjectAttributes attributes1, PxFilterData filterData1, PxPairFlags &pairFlags, const void *constantBlock, PxU32 constantBlockSize)

Implementation of a simple filter shader that emulates PhysX 2.8.x filtering.

This shader provides the following logic:

Filter mask logic: Given the two PxFilterData structures fd0 and fd1 of two collision objects, the pair passes the filter if the following conditions are met:
1) Collision groups of the pair are enabled
2) Collision filtering equation is satisfied
