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