[Federico Mena Quintero <federico src gnome org>]

    Add gnome_rr_output_is_laptop()
    
    Detecting a laptop's built-in LCD takes some trickery, so we now
    have a function to do it.
    
    You would think that all versions of RANDR would make this easy,
    but noooooo, why cater to userspace's needs when you can just
    throw together APIs without ever thinking of how people may
    need to use them.
