\brief A class for drawing round scales
QwtRoundScaleDraw can be used to draw round scales.
The circle segment can be adjusted by QwtRoundScaleDraw::setAngleRange().
The geometry of the scale can be specified with
QwtRoundScaleDraw::moveCenter() and QwtRoundScaleDraw::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.
