Description:

            SUBROUTINE PGSFS (FS)
            INTEGER  FS
      
       Set the Fill-Area Style attribute for subsequent area-fill by
       PGPOLY, PGRECT, or PGCIRC.  Four different styles are available: 
       solid (fill polygon with solid color of the current color-index), 
       outline (draw outline of polygon only, using current line attributes),
       hatched (shade interior of polygon with parallel lines, using
       current line attributes), or cross-hatched. The orientation and
       spacing of hatch lines can be specified with routine PGSHS (set
       hatch style).
      
       Argument:
        FS     (input)  : the fill-area style to be used for subsequent
                          plotting:
                            FS = 1 => solid (default)
                            FS = 2 => outline
                            FS = 3 => hatched
                            FS = 4 => cross-hatched
                          Other values give an error message and are
                          treated as 2.
