    Procedure:  _seresz.p
    
    Purpose:    Resize the Frame and Editor widgets of a Section Editor
                Window.

    Syntax :    RUN adeuib/_seresz.p ( INPUT p_Window ).

    Parameters: p_Window   Section Editor window handle.
                           If not valid, routine uses SELF handle.
    
    Description:
        Resize Algorithm:
            1. If Window W grew, grow the Frame's W same as Window W.
            2. If Window H grew, then size the Frame's H using this         
               calculation:
               
                 Frame:HEIGHT = Window:HEIGHT - #Unusable-Rows
                 
                 ( #Unusable-Rows = Frame:ROW - 1 )
                 
               The #Unsable-Rows are the number of rows occupied by
               the Sections Radio-set, etc.

            3. Size the field-level editor widget to the window LESS the
               Frame Border Widths.  Note that the HEIGHT must take into
               account the rows occupied by the Section Radio-Set, etc..
               just like #2 abovr.
            4. If Window W or H shrank, we leave the Frame's W and H alone.
               We do this to avoid getting scrollbars on the frame.
    
    Notes  : Caller must pass a valid window widget-handle or the routine
             must be called from a window widget trigger.
