* The ShapeSpanIterator returned will be fully constructed

* appropriate BasicStroke and normalization parameters taken
* from the SunGraphics2D object and be ready to start returning
* spans.
*
* Note that the caller is responsible for calling dispose()
* on the returned ShapeSpanIterator inside a try/finally block.
* <pre>
* ShapeSpanIterator ssi = LoopPipe.getStrokeSpans(sg2d, s);
* try {
* // iterate the spans from ssi and operate on them
* } finally {

*
* REMIND: This should return a SpanIterator interface object
* but the caller needs to dispose() the object and that method
* is only on ShapeSpanIterator.
* TODO: Add a dispose() method to the SpanIterator interface.
