[Jonas Ådahl <jadahl src gnome org>]

commit c98bab83270c68dfac4e479cbe957387e1c2e5c4

    monitor-manager: Make logical monitor from point API take floats
    
    Change meta_monitor_manager_get_logical_monitor_at() to use floats,
    replace users of meta_monitor_manager_get_monitor_at_point() to use the
    API that returns a logical monitor and remove the now unused function.
