Returns
DecomposeRigidBodyOrientation(float4x4)
Physics internally represents all rigid bodies in world space.
If a static body is in a hierarchy, its local-to-world matrix must be decomposed when building the physics world.
This method returns a world-space orientation that would be decomposed for such a rigid body.
