Warning
gtk_tree_view_set_destroy_count_func has been deprecated since version 3.4 and should not be used in newly-written code. Accessibility does not need the function anymore.
This function should almost never be used. It is meant for private use by
ATK for determining the number of visible children that are removed when the
user collapses a row, or a row is deleted.
