voidsetViewportRegion(constSbViewportRegion&newRegion)constSbViewportRegion&getViewportRegion()const
          Sets/returns current viewport region to use for action. Even though  the  picking  operation  may  not
          involve a window per se, some nodes need this information to determine their size and placement.
