\brief A class for drawing scales
QwtScaleDraw can be used to draw linear or logarithmic scales.
A scale has a position, an alignment and a length, which can be specified .
The labels can be rotated and aligned
to the ticks using setLabelRotation() and setLabelAlignment().
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.
