	\brief Ray-triangle intersection test.
	
	Returns impact distance (t) as well as barycentric coordinates (u,v) of impact point.
	Use NxComputeBarycentricPoint() in Foundation to compute the impact point from the barycentric coordinates.
	The test performs back face culling or not according to 'cull'.

	\warning #NxCreatePhysicsSDK() must be called before using this function.
