DESCRIPTION

polf fills polygonal areas using the current texture pattern, color, and writemask.  It takes two arguments: an array of points and the number of points in that array.  Polygons are represented as arrays of points.  The first and last points are automatically connected to close a polygon.  The points can be expressed as integers, shorts, or real numbers, in 2D or 3D space.  Two-dimensional polygons are drawn with z=0.  After the polygon is filled, the current graphics position is set to the first point in the array.  The results are undefined if the polygon is not convex.
