2003-12-10  Mark McLoughlin  <mark@skynet.ie>

        Utility functions for multi-screen applications which need
        to ensure launched applications appear on a certain screen.
        See bug #95897.

        * gdk/gdkspawn.h: header for multi-screen launching
        support.

        * gdk/Makefile.am: install gdkspawn.h.

        * gdk/x11/Makefile.am:
        * gdk/x11/gdkspawn-x11.c:
        (gdk_spawn_make_environment_for_screen): private function
        to create an environment vector with DISPLAY set appropriately
        for the screen.
        (gdk_spawn_on_screen): multi-screen version of g_spawn_async().
        (gdk_spawn_on_screen_with_pipes): version of g_spawn_async_with_pipes().
        (gdk_spawn_command_line_on_screen): version of g_spawn_command_line_async().

        * gdk/linux-fb/Makefile.am,
          gdk/linux-fb/gdkspawn-fb.c: linux-fb impl.

        * gdk/win32/Makefile.am,
          gdk/win32/gdkspawn-win32.c: win32 impl.
