gion lying within the rectangle having width
            equal to the current line width,
            length equal to the actual length of the line,
            and centered on the mathematical line segment.
            The coverage value for each fragment is the window coordinate area
            of the intersection of the rectangular region with the corresponding
            pixel square.
            This value is saved and used in the final rasterization step.
