NAME
     splf, splfi, splfs, splf2, splf2i, splf2s - draws a shaded filled polygon

FORTRAN 77 SPECIFICATION
     subroutine splf(n, parray, iarray)
     integer*4 n
     real parray(3,n)
     integer*2 iarray(n)

     subroutine splfi(n, parray, iarray)
     integer*4 n
     integer*4 parray(3,n)
     integer*2 iarray(n)

     subroutine splfs(n, parray, iarray)
     integer*4 n
     integer*2 parray(3,n)
     integer*2 iarray(n)

     subroutine splf2(n, parray, iarray)
     integer*4 n
     real parray(2,n)
     integer*2 iarray(n)

     subroutine splf2i(n, parray, iarray)
     integer*4 n
     integer*4 parray(2,n)
     integer*2 iarray(n)

     integer*4 n
     integer*2 parray(2,n)
     integer*2 iarray(n)

     All of the above routines are functionally the same.  They differ only in
     the type declarations of their parameters and in whether they assume a
     two- or three-dimensional space.

PARAMETERS
     n        expects the number of vertices in the polygon.  There can be no
              more than 256 vertices in a single polygon.

     parray   expects an array containing the vertices of a polygon.

     iarray   expects the array containing the color map indices which
              determine the intensities of the vertices of the polygon

DESCRIPTION
     splf draws Gouraud-shaded polygons using the current pattern and
     writemask.  Polygons are represented as arrays of points.  The first and
     last points automatically connect to close a polygon.
     If you want to use backfa, you should specify the vertices in counter-
     clockwise order.

     After the polygon is drawn, the current graphics position is set to the
     first point in the array.

     splf must be used in color map mode.
