In pygtk custom cellrenderers were done inheriting gtk.GenericCellRenderer, and overriding the on_* methods. Now we inherit Gtk.CellRenderer and the methods to override changed to do_* . The destroy signal was moved to Gtk.Widget [1] so the Gtk.CellRenderer doesn't have it anymore. Now we do the cleanup in the python destructor method. A testcase tests/graphics/customdestroy.py shows how is done. tests/graphics/cellrenderericon.py tests the usage.

Since GTK+3 Gtk.CellRenderer doesn't have a destroy signal anymore.

We can do the cleanup in the python destructor method instead.
