[glom/gtkmm4v3: 11/21] Remove use of GimpRuler, sadly.

[Murray Cumming <murrayc src gnome org>]

commit d919e32a1ee3a48454e8fcc39d9ad06a05fe1972
Author: Murray Cumming <murrayc murrayc com>

    Remove use of GimpRuler, sadly.
    
    The code needs to be updated to GTK+4, but Gimp is not yet fully
    ported to GTK+3.
    Replacement of API such as gdk_window_get_effective_parent() is
    apparently much work for me to want to maintain it outside of Gimp:
