Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/BulletCollision/CleanPairCallback.cs

A small internal class used by the Bullet physics port. CleanPairCallback implements IOverlapCallback and, for a given BroadphaseProxy, iterates overlapping BroadphasePair objects and asks the pair cache to clean any pair involving that proxy using the physics dispatcher.
