*
* This class converts from 2Geom path representation to the Cairo representation.
* Use it to simplify visualizing the results of 2Geom operations with the Cairo library,
* for example:
* @code
* CairoPathSink sink(cr);
* sink.feed(pv);
* cairo_stroke(cr);
* @endcode
*
* Currently the flush method is a no-op, but this is not guaranteed
* to hold forever.
