	/* 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.
