/**

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

 * The Fill element specifies how the area of the geometry will be filled.

 * There are two types of fills, solid-color and repeated GraphicFill. The repeated 

 * graphic fill is selected only if the GraphicFill element is present. If the Fill

 * element is omitted from its parent element, then no fill will be rendered. The 

 * GraphicFill and CssParameter elements are discussed in conjunction with the 

 * Stroke element in Section 11.1.3. Here, the CssParameter names are �fill� 

 * instead of �stroke� and �fill-opacity� instead of �stroke-opacity�. None of the

 * other CssParameters in Stroke are available for filling and the default value

 * for the fill color in this context is 50% gray (value �#808080�).
