/**
 * This class implements a multiImage extension to SVG.
 *
 * The 'multiImage' element is similar to the 'image' element (supports
 * all the same attributes and properties) except.
 * <ol>
 *    <li>It can only be used to reference raster content (this is an
 *        implementation thing really)</li>
 *    <li>It has two addtional attributes: 'pixel-width' and
 *        'pixel-height' which are the maximum width and height of the
 *        image referenced by the xlink:href attribute.</li>
 *    <li>It can contain a child element 'subImage' which has only
 *        three attributes, pixel-width, pixel-height and xlink:href.
 *        The image displayed is the smallest image such that
 *        pixel-width and pixel-height are greater than or equal to the
 *        required image size for display.</li>
 * </ol>
