+MScalingSettings interface manages X-axis and Y-axis scaling factors of CFbsDrawDevice interface.
+
+The interface could be retrieved calling CFbsDrawDevice::GetInterface() with 
+KScalingSettingsInterfaceID as an argument.
+If the draw device does not have support for scaling, MScalingSettings cannot be retrieved.
+
+MScalingSettings interface lifetime is the same as the lifetime of CFbsDrawDevice
+interface, which creates it. 
+Do not try to delete MScalingSettings interface pointer!
+
+MScalingSettings interface offers following methods: 
+Get(), Set(), IsScalingOff().
