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

This shader provides the following logic:

If one of the two filter objects is a trigger, the pair is acccepted and [PxPairFlag::eTRIGGER_DEFAULT] will be used for trigger reports

Else, if the filter mask logic (see further below) discards the pair it will be suppressed ([PxFilterFlag::eSUPPRESS])

Else, the pair gets accepted and collision response gets enabled ([PxPairFlag::eCONTACT_DEFAULT])

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
