DESCRIPTION

poly takes two arguments:  an array of points and the number of points in that array.  A polygon is represented as an array of points.  The first and last points are automatically connected to close the 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.  The polygon is outlined using the current linestyle, linewidth, color, and writemask.
