path constructed from straight lines, quadratic and cubic (Bezier)
curves and elliptical arcs. This interface is identical to that of
PathIterator except it can return SEG_ARCTO from currentSegment,
also the array of values passed to currentSegment must be of length
7 or an error will be thrown.
This does not extend PathIterator as it would break the interface
contract for that class.</div>
