0021 //! - Add        : 2nd level BVH does not contain any of the selection's sensitive entities and they must be
0022 //! added;
0023 //! - Remove     : all sensitive entities of the selection must be removed from 2nd level BVH;
0024 //! - Renew      : 2nd level BVH already contains sensitives of the selection, but the its complete update
0025 //! and removal is required. Therefore, sensitives of the selection with this type of update
0026 //! must be removed from 2nd level BVH and added after recomputation.
0027 //! - Invalidate : the 2nd level BVH needs to be rebuilt;
0028 //! - None       : entities of the selection are up to date.
