      * Draws an anti-aliased line using Wu's algorithm.

      * The algorithm produces smooth lines by drawing pairs of pixels at each
      * x-coordinate (or y-coordinate for steep lines), with intensities based on
      * the line's distance from pixel centers.
      *
-     * Example usage:
-     * {@code
-     * List<Pixel> linePixels = WusLine.drawLine(10, 20, 100, 80);
-     * for (Pixel p : linePixels) {
-     *     drawPixel(p.point.x, p.point.y, p.intensity);
