//     Function: NodeTransitionCache::set_transition
//       Access: Public
//  Description: This flavor of set_transition() accepts a pointer to
//               a NodeTransition only.  It infers the type of the
//               NodeTransition from the pointer.  However, it is not
//               valid to pass a NULL pointer to this flavor of
//               set_transition; if the pointer might be NULL, use the
//               above flavor instead (or just call clear_transition).
