[vtkusers] fix position of vtkAxesActor

[Benoist Laurent]

Hi,

I tried to setup some axes actor as follow :
     vtkSmartPointer<vtkAxesActor> axes =
         vtkSmartPointer<vtkAxesActor>::New();

     vtkSmartPointer<vtkOrientationMarkerWidget> widget =
         vtkSmartPointer<vtkOrientationMarkerWidget>::New();
     widget->SetOutlineColor( 0.9300, 0.5700, 0.1300 );
     widget->SetOrientationMarker( axes );
     widget->SetInteractor( renderWindowInteractor );
     widget->SetViewport( 0.0, 0.0, 0.4, 0.4 );
     widget->SetEnabled( 1 );
     widget->InteractiveOn();


I was successfull!
But the axes actor if in the center of the widget's viewport.
Therefore, I can't put the axes in the extreme left corner of the  
screen.

Any idea how should I do ?


Thanks.
Benoist
