[vtkusers] Calling GetPixelData on vtkOpenGLRenderWindow

When I call getPixelData on a vtkOpenGLRenderWindow after a camera
movement all that is returned is a black image although there is an
image on the screen.  Also, I think the cause may stem from this: when I
call a ren->GetActiveCamera()->Elevate(10) for example, and call for a
render, I don't get any update on the window.  Any ideas on this?
