    quartz: move tooltips window to the topmost level
    
    so they can appear on top of popup menus. Also, reorder the switch()
    statement in window_type_hint_to_level() so it resembles the stacking
    order, to avoid confision like this in the future. Fixes bug 688512.
    (cherry picked from commit 1a2509a6ab7f35caae758c2b31f40ef90d4fa94a)
