        /* ArdourWindows are not dialogs (they have no "OK" or "Close" button) but
           they should be considered part of the same "window level" as a dialog. This
           works on X11 in that: 

           (a) there are no window "levels"
           (b) they will float above normal windows without any particular effort
	   (c) present()-ing them will make a utility float over a dialog or
               vice versa.

           Some X11 Window managers (e.g. KDE) get this wrong, and so we allow the user
           to select what type of window hint is used.

           GTK+ on OS X uses different levels for DIALOG and UTILITY, and Cocoa has a bug/design
           issue that it will not transfer keyboard focus across levels when hiding a window.
           So on OS X, we use DIALOG for all ArdourWindows to ensure that keyboard focus
           will return to the main window(s) when this window is hidden.
