041 * The GraphicStroke element both indicates that a repeated-linear-graphic stroke type will be used.

043 * </p>
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.
