    compositor: Base zoom update or refresh rate
    
    Bug: 15391
    
    Previously, the zoom update was based on XRandr refresh rate ÷ 2, or
    30 by default if not available.
    
    But that XRandr code was removed along with the removal of the fake
    vblank sync code in favor of XPresent or GLX.
    
    Base the zoom update on half the refresh rate of the primary monitor (if
    available from GDK), so we would get the same results as with 4.12.
