; Sets the plotter's Auto Update feedback field as appropriate for
; the current value of !g.frozen.  This should be called after ever
; time that !g.frozen changes state.  Users should use the Auto Update
; menu on the plotter or the freeze and unfreeze procedures to change
; !g.frozen rather than change it directly.  In that case, it is not
; necessary to call this procedure directly.
