[vtkusers] Close renderWindow after terminating interactorWindow

[ChiaWeng Boon]

Hi,

I have created a vtkRenderWindowInteractor.  To stop the interactor
from working further, I can type 'e' or 'q'.   But after that I cannot
close the RenderWindow.

ren1 = vtkRenderer::New();
renWin = vtkRenderWindow::New();
renWin->AddRenderer(ren1);
iren = vtkRenderWindowInteractor::New();
iren->SetRenderWindow(renWin);
ren1->AddActor(contActor);
ren1->SetBackground(1,1,1); // Background color white
renWin->Render();	
iren->Start();

After I am done, I press 'e'.  Then I call python to run:
iren->GetRenderWindow()->Finalize();

This did not work.  Everything works fine when I do not have the
interactor, i.e., the renderWindow closes nicely.  I hope someone can
help me out.
