/**
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: 
Orientation()
