Added viewport functionality: The viewport shall estimate if the user is looking at the display (in focus) or not. This is done by vector calculation using roll, pitch and yaw angles. The first usecase is to enable the motion detection feature: It is only active if the user is looking at the display. Still in development state => deactivated by compile switch
