Help me understand this. Is QwtPlotCurve::legendItem() supposed to
return a new instance each time it is called? Like other parts of Qt
and Qwt, I thought it was returning the address of an instance that the
QwtPlotCurve controlled. If the call returns a new instance, how does
this new instance become associated with the QwtPlotCurve? Is it
necessary to call QwtPlotCurve::setLegendItem() with the new instance?
