\brief A class for drawing round scales
QwtRoundScaleDraw can be used to draw round scales.
The circle segment can be adjusted by setAngleRange().
The geometry of the scale can be specified with
moveCenter() and setRadius().
After a scale division has been specified as a QwtScaleDiv object
using QwtAbstractScaleDraw::setScaleDiv(const QwtScaleDiv &s),
the scale can be drawn with the QwtAbstractScaleDraw::draw() member.
