    044     * The Graphic sub-element specifies the linear graphic. Proper stroking with a linear graphic
    045     * requires two hot-spot points within the space of the graphic to indicate where the rendering line
    046     * starts and stops. In the case of raster images with no special mark-up, this line will be assumed
    047     * to be middle pixel row of the image, starting from the first pixel column and ending at the last
    048     * pixel column.
