Remarks

Box3D uses this internally for the broad phase, and exposes it because it is useful for organizing other spatial game data. It is private data placed in the public header for performance.

A tree returned by b3DynamicTree_Create owns heap memory and must be released with b3DynamicTree_Destroy.
