[vtkusers] Disabling rotation

[Eric E. Monson]

Hey Robbie,

You just need to set the interactor style to vtkInteractorStyleImage:

http://www.vtk.org/doc/nightly/html/classvtkInteractorStyleImage.html

You can see the examples and tests linked from that page, but it will be something like:

vtkSmartPointer<vtkInteractorStyleImage> imageStyle =
    vtkSmartPointer<vtkInteractorStyleImage>::New();
widget->GetRenderWindow()->GetInteractor()->SetInteractorStyle(imageStyle);
