sl@0: The class offers a simple interface to add, remove video display window and supports graphics surfaces.
sl@0: It also offers some display handling funcations like video extension, scalling and rotation. 
sl@0: 
sl@0: This class has one static function through which client can construct, initialise and get 
sl@0: pointer of the class.
