Set a Grid Graphical Object

Description:

     Replace a grob or a descendant of a grob.

Usage:

     grid.set(gPath, newGrob, strict = FALSE, redraw = TRUE) 
     setGrob(gTree, gPath, newGrob, strict = FALSE) 

Arguments:

   gTree: A gTree object.

   gPath: A gPath object. For 'grid.set' this specifyies a grob on the
          display list.  For 'setGrob' this specifies a descendant of
          the specified gTree. 

  strict: A boolean indicating whether the gPath must be matched
          exactly. 

 newGrob: A grob object. 

  redraw: A logical value to indicate whether to redraw the grob. 

Details:

     'setGrob' copies the specified grob and returns a modified grob.

     'grid.set' destructively replaces a grob on the display list. If
     'redraw' is 'TRUE' it then redraws everything to reflect the
     change.

     These functions should not normally be called by the user.

Value:

     'setGrob' returns a grob object;  'grid.set' returns 'NULL'.
