/*
* @brief The 'QmitkRenderWindowUtilityWidget' can be added to a 'QMitkRenderWindowWidget' to extend it
*        with window-specific utilities.
*
*        It offers to select the viewing direction of the window, as well as a 'QmitkSliceNavigationWidget'
*        to scroll through the current view direction.
*        In addition, it contains a 'QmitkSynchronizedNodeSelectionWidget' that controls renderer-specific
*        properties and shown nodes, as well as a synchronization-group selector to share this state with
*        other render windows.
