* Used to render an interior "fill" and an outlining "stroke" for a polygon or other 2D-area
* geometry. If a point or line are used, the fill is ignored and the stroke is used as described in
* the LineSymbol. A missing Geometry element selects the default geometry. A missing Fill or Stroke
* element means that there will be no fill or stroke plotted, respectively. The contained elements
* are in the conceptual order of their being used and plotted using the "painters model", where the
* Fill will be rendered first, and then the Stroke will be rendered on top of the Fill.
