31  * Utility class that converts a Shape object into the corresponding
32  * SVG element. Note that this class analyzes the input Shape class
33  * to generate the most appropriate corresponding SVG element:
34  * + Polygon is mapped to polygon
35  * + Rectangle2D and RoundRectangle2D are mapped to rect
36  * + Ellipse2D is mapped to circle or ellipse
37  * + Line2D is mapped to line
38  * + Arc2D, CubicCurve2D, Area, GeneralPath and QuadCurve2D are mapped to
39  * path.
40  * + Any custom Shape implementation is mapped to path as well.
