Sometimes-spurious Render() in vtkInteractorStyle::StopState()
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
In vtkInteractorStyle::StopState(), a Render() is triggered even if the vtkRenderWindow's DesiredUpdateRate isn't changed. The Render() should only occur when the update rate is changed.
Attached is a patch which fixes the problem.
