40 to the user-specified-position vs. program-specified-position and
41 user-specified-size vs. program-specified-size flag. (It always
42 sets program-specified whenever the program requests a change
43 in its size or position, even when this came from direct user
44 request.) So we provide external entry points to fix this after
45 the program requested a size or position change. If it turns
46 out that the user-specified-position flag needs to be set at the
47 *same* time that the geometry change request is made, then we
48 will have to duplicate the entire root_geometry_manager() method;
