[vtkusers] Set Image position on vtkActor2D

[Matteo]

Found the problem, SetPosition was needing coordinated in pixel but 
SetPosition2 in normalized format.
So with this code now it works:

             
ImageActor->GetPositionCoordinate()->SetCoordinateSystemToNormalizedViewport();
             
ImageActor->GetPosition2Coordinate()->SetCoordinateSystemToNormalizedViewport();
             ImageActor->SetPosition(0.25,0.25);
             ImageActor->SetWidth(0.5);
             ImageActor->SetHeight(0.4);

Regards
