vtkRenderWindowInteractor::CreateRepeatingTimer does not work on Windows unless the interactor is initialized
When running a vtkRenderWindowInteractor with a timer to create an animation, on Windows you need to run interactor->Initialize() before or the timer won't work. I don't know if it's the intended behavior but in that case I suggest to fix the default behavior so we would need to initialize the interactor in each OS.
