/**

 * Implements the Graphic element of an SLD implementation specification.<p>

 * A Graphic is a �graphic symbol� with an inherent shape, color(s), and possibly size. A

 * �graphic� can be very informally defined as �a little picture� and can be of either a raster

 * or vector-graphic source type. The term �graphic� is used since the term �symbol� is

 * similar to �symbolizer� which is used in a different context in SLD.<p>

 * If the Graphic element is omitted from the parent element, then nothing will be plotted.<p>

 * Graphics can either be referenced from an external URL in a common format (such as

 * GIF or SVG) or may be derived from a Mark. Multiple external URLs and marks may be

 * referenced with the semantic that they all provide the equivalent graphic in different

 * formats. The �hot spot� to use for positioning the rendering at a point must either be

 * inherent in the external format or is defined to be the �central point� of the graphic,

 * where the exact definition �central point� is system-dependent.<p>

 * The default if neither an ExternalGraphic nor a Mark is specified is to use the default

 * mark of a �square� with a 50%-gray fill and a black outline, with a size of 6 pixels,

 *
