/**
* Fills a (closed) polygon, as defined by a pair of arrays, which hold the <i>x</i> and <i>y</i>
* coordinates.
*
* <p>This draws the polygon, with <code>nPoint</code> line segments. The first <code>
* nPoint - 1</code> line segments are drawn between sequential points (<code>
* xPoints[i],yPoints[i],xPoints[i+1],yPoints[i+1]</code>). The final line segment is a closing
* one, from the last point to the first (assuming they are different).
*
* <p>The area inside of the polygon is defined by using an even-odd fill rule (also known as the
* alternating rule), and the area inside of it is filled.
*
* @param xPoints array of the <code>x</code> coordinates.
* @param yPoints array of the <code>y</code> coordinates.
* @param nPoints the total number of points in the polygon.
* @see java.awt.Graphics#drawPolygon(int[], int[], int)
