    magnifier: Avoid cursor visibility changes on startup
    
    When initializing the shell, we create the magnifier, and (normally)
    let it disabled. This still toggles cursor visibility on, which is
    not right since there's other considerations to take during
    initialization.
    
    Only do this after actual changes to the magnifier state, so
    initialization is left unperturbed.
