GnomeCanvasGroup has pointers to the list of its children:

struct _GnomeCanvasGroup {
	GnomeCanvasItem item;

	/* Children of the group */
	GList *item_list;
	GList *item_list_end;

the two GList* point to the same list, item_list->data is the bottom
item and item_list_end the top item.
If one of the children is a group, it has its own children of course.
