	I just noticed the need for something like this. I would have
thought something like

GdkDisplay *gdk_library_lookup_display (const gchar *display_name);

	would have been nice, or that the lookup would be implicit in
gdk_open_display. Or maybe it should be lookup_screen, since that's
the lowest denominator of DISPLAY really ...

	While we're on it, it might be nice to have a utility function
which takes a GdkScreen and munges the display name with the screen
number. This is a pain to do by hand and both the panel and nautilus
needs this for launching apps on different screens.

	Another thing I noticed was that there is a
gtk_plug_new_for_display, but no gtk_window_new_for_display. How
come?

	Anyway, I managed to answer without addressing your questions -
how helpful of me :-)

Good Luck,
Mark.
