 * The GtkCellAccessibleParent interface should be supported by any object
 * which contains children which are flyweights, i.e. do not have corresponding
 * widgets and the children need help from their parent to provide
 * functionality. One example is GtkTreeViewAccessible where the children
 * GtkCellAccessible need help from the GtkTreeViewAccessible in order to
 * implement atk_component_get_extents().
