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

A small helper class used during broadphase ray queries in the Bullet port. It wraps a BroadphaseRayCallback and implements the ICollide interface to process DbvtNode leaves by extracting their DbvtProxy and forwarding them to the ray callback; also supports pooling via Dispose.
