QPainterPathStroker setWidth/setCurveThreshold

Hello,

The following 2 code snippets behave quite differently:
a)

        QPainterPathStroker stroker;
        stroker.setWidth(buffWidth);
        stroker.setCurveThreshold(0.01);

b)

        QPainterPathStroker stroker;
        stroker.setCurveThreshold(0.01);
        stroker.setWidth(buffWidth);

As you might notice the only difference is the ordering of setWidth and setCurveThreshold.
in b) setCurveThreshold has no effect, as the internal data is overwriten when calling setWidth:

void QPainterPathStroker::setWidth(qreal width)
{
    Q_D(QPainterPathStroker);
    if (width <= 0)
        width = 1;
    d->stroker.setStrokeWidth(qt_real_to_fixed(width));
}
...
class Q_GUI_EXPORT QStroker : public QStrokerOps
...
    void setStrokeWidth(qfixed width)
    {
        m_strokeWidth = width;
        m_curveThreshold = qt_real_to_fixed(qBound(0.00025, 1.0 / qt_fixed_to_real(width), 0.25));
    }

QDashStroker seems not to have this problem.

This actually is a minor flaw, but it took me literally days to find this solution (by chance) as i took huge efforts to work around accuracy problems using QPainterPathStroker. They all vanished by just reordering the 2 Lines.

I think that setWidth should not overwrite a explicit setting made by setCurveThreshold.

QPainterPathStroker is a great tool by the way. The only one o could find that does so by using curves and not polygons.
