Subject: Remove unused code and make a lot of stuff private

2005-01-01  Marco Pesenti Gritti  <marco@gnome.org>

        * ps/gtkgs.c: (gtk_gs_class_init), (gtk_gs_get_orientation),
        (output), (stop_interpreter), (gtk_gs_emit_error_msg),
        (gtk_gs_zoom_to_fit), (gtk_gs_set_zoom):
        * ps/gtkgs.h:

        Remove unused code and make a lot of stuff private
