   moves in a clockwise direction about the interior of the polygon.
            The polygon's winding is said to be counterclockwise if the imaginary
            object following the same path moves in a counterclockwise direction
            about the interior of the polygon.
            <code class="function">glFrontFace</code> specifies whether polygons with clockwise winding in window coordinates,
            or counterclockwise winding in window coordinates,
            are taken to be front-facing.
