    compositor: Don't repaint a screen of zero size
    
    Bug: 15852
    
    If no monitor is connected for a given screen, it's reported size will
    be 0.
    
    In that case, trying to repaint the screen using GLX for vsync will
    crash.
    
    Add a test to make sure the size of the screen is a thing, before
    queuing up a repaint.
