This then defines the window size and position. If you don't define a channel viewport, it will fill this entire window. Nothing is being scaled. I'm not sure what you expect viewport is doing, but it really just defines the 2D area covered by the window or channel. How this is used for rendering is defined by the compound's wall description.
