Thu Jun 20 16:49:00 2002  Owen Taylor  <otaylor@redhat.com>

        * gdk/gdkdisplaymanager.[ch] gdk/gdk.[ch] gdk/gdkdisplay.c
        gdk/gdkinternals.h gdk/x11/gdkdisplay-x11.c
        gdk/win32/gdkdisplay-win32.c: Add a singleton object that
        we can use to get notification when displays
        appear / disappear or the default display changes.

        gdk_set_default_display() => gdk_display_manager_set_default_display()
        gdk_list_displays() => gdk_display_manager_list_displays().
        (#85696)

        * gdk/Makefile.am gdk/gdkmarshalers.list: Add marshaler
        generation.

        * gdk/gdkintl.h: Add this.

        * gtk/gtkmain.c: Add gtk_parse_args() that initializes
        GTK+ without opening a display.

        * gtk/gtkmain.c: Set things up so if a module
        exports gtk_module_init() and gtk_module_display_init(),
        then we treat it as multihead aware, otherwise,
        we only initialize it after the default display is set.
