    Trick g-ir-scanner
    
    g-ir-scanner's handling of #defines is really rudimentary,
    so we have to trick it to pick up PANGO_ATTR_TO_TEXT_END
    as a constant with value 0, and then override the value
    with an annotation.
    
    See https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/369
