    quartz: move dialogs to the same window level as utility windows
    
    window_type_hint_to_level(): applied patch from Paul Davis which moves
    dialogs to NSFloatingWindowLevel. This is not quite the perfect
    solution, but it's a pragmatic fix that makes apps which have both
    window types much more usable, and prevents dialog from disappearing
    under an application's main window.
    (cherry picked from commit 59d49e1566faeed80d2b2052c42fe6c5e9153190)
