[vtkusers] Display a 2D image beside a 3D object

[jean-michel.rouet at philips.com]

Hi all,

I was wondering how I could split a renderwindow into 2 viewports, having 
the left side display a 3D object (polydata), and the right side display a 
2D image whose content might change of course.

I'm able to do that almost, by using a vtkImageActor on the right side, 
but unfortunately, the camera does not stay still when one click with the 
mouse.
So 2 questions: 
        is that possible to disable camera movements on the right side 
viewport?
        Is there a better vtk class for displaying a 2D image in a 
viewport, other than vtkImageActor?
