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