 *
 * 4. The child is always positioned at the location

 *
 * the net result is the child has a border width which is always
 * what the user asked for;  but none of it is ever seen, it's all
 * clipped by the shell (parent).  The user sees the border
 * of the shell which is the size he set the child's border to.
 *
 * In the DEC window manager world the window manager does
 * exactly the same thing with the window it puts around the shell.
 * Hence the shell and child have a border width just as the user
 * set but the window manager overrides that and only a single
 * pixel border is displayed.  In a non-wm environment the child 
 * appears to have a border width, in reality this is the shell
