[vtkusers] Multiple renderwindows/interactor concurrently?

[Emiliano Beronich]

Hi Arnold,

On Windows, instead of using a thread for every renderwindow, you can 
use SetInstallMessage() to prevent the Message callback set by the 
interactor and then let your own method to manage every message 
apropiately. This method is supposed to pass the message to the 
interactor. In this case, you don't need to call Start. Maybe you can 
try an approach like this on Unix but I don't know exactly how you can 
do this.
