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
DESCRIPTIONsplf 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 backface, 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.
