[vtkusers] Change Render Window

[Kall, Bruce A.]

Clint,

Thanks.  This works great.  It's not intuitive why you would use Finalize()
before changing the widow based on the description:

"Finalize the rendering process"

Sure seems like you would call this 'after' you changed the windowid, but
it does what it does and my problem is solved!

Thanks,
Bruce
