I understand this completely.  I just do not want the program (lynx)
making the determination about when a screen contains garbage.  As I
stated earlier, only the user can make that determination and press ^L
to force a redraw.  The redraw should clear the screen and repaint it:

    void redraw_screen ()
    {
       SLsmg_suspend_smg ();
       SLsmg_resume_smg ();
    }
        
This will force SLANG to clear the screen and the redraw it.  However,
I think that the only way this should get called is if the user
presses Ctrl-L.
