As it says, there is only *one* display surface, and any non-displayed
surface must be blitted (copied) onto the display surface for
visibility.  So all "pygame.display" methods refer to that one display
surface.  Non displayed surfaces, on the other hand, do need to be
instantiated with "pygame.Surface"
