[vtkusers] VTK tutorial, step 5 (Cone5), OSX-Cocoa: fails to capture keyboard events

[Clinton Stimpson]

I agree thorough testing is needed.  For background rendering, just 
don't make a vtkRenderWindowInteractor.
On other platforms, the new window comes to front anyways.  And if it 
was a bundled app doing this background work, the process is already 
transformed.
