47    @brief
48        OverlayGroup does almost exactly what it says: It groups OrxonoxOverlays together.
49        You can scroll the entire group by a certain amount. Scale however works differently
50        than expected: Each OrxonoxOverlay scales individually. That's quite useful when you
51        create your HUD with an OverlayGroup and then want to alter its size.
