+MDrawDeviceOrientation interface manages the orientation degrees of CFbsDrawDevice interface.
+
+The interface could be retrieved calling CFbsDrawDevice::GetInterface() with 
+KOrientationInterfaceID as an argument.
+If the drawing device does not have support for moving origin, MDrawDeviceOrientation cannot be retrieved.
+   
+MDrawDeviceOrientation interface lifetime is the same as the lifetime of CFbsDrawDevice
+interface, which creates it. 
+Do not try to delete MDrawDeviceOrientation interface pointer!

+MDrawDeviceOrientation interface offers following method:
