    1.23 +MDrawDeviceOrigin interface manages the origin point of CFbsDrawDevice interface.
    1.24 +
    1.25 +The interface could be retrieved calling CFbsDrawDevice::GetInterface() with 
    1.26 +KDrawDeviceOriginInterfaceID as an argument.
    1.27 +If the drawing device does not have support for moving origin, MDrawDeviceOrigin cannot be retrieved.
    1.28 +   
    1.29 +MDrawDeviceOrigin interface lifetime is the same as the lifetime of CFbsDrawDevice
    1.30 +interface, which creates it. 
    1.31 +Do not try to delete MDrawDeviceOrigin interface pointer!
    1.32 +   
    1.33 +MDrawDeviceOrigin interface offers following methods: 
    1.34 +Get(), Set().
