 * DESCRIPTION:
 *
 * DispCmds - different display commands which take data and put it in
 *      a storage space provided by a given VMDDisplayList object.
 *
 * Notes:
 *      1. All coordinates are stored as 3 points (x,y,z), even if meant
 * for a 2D object.  The 3rd coord for 2D objects will be ignored.
