GtkSorterChange

The sorter change cannot be described by any of the other enumeration values

The sort order was inverted. Comparisons that returned gtk.types.Ordering.Smaller now return gtk.types.Ordering.Larger and vice versa. Other comparisons return the same values as before.

The sorter is less strict: Comparisons may now return gtk.types.Ordering.Equal that did not do so before.

The sorter is more strict: Comparisons that did return gtk.types.Ordering.Equal may not do so anymore.
