//
//.F ScaleDraw::setAngleRange
// Adjust the baseline circle segment for round scales.
//
//.u Syntax
//.f void ScaleDraw::setAngleRange(double angle1, double angle2)
//
//.u Parameters
//.p double angle1, double angle2
// boundaries of the angle interval in degrees.
//
//.u Description
// The baseline will be drawn from min(angle1,angle2) to max(angle1, angle2).
// The settings have no effect if the scale orientation is not set to
// ScaleDraw::Round. The default setting is [ -135, 135 ].
// An angle of 0 degrees corresponds to the 12 o'clock position,
// and positive angles count in a clockwise direction.
//
//.u Note
//.i
// -- The angle range is limited to [-360, 360] degrees. Angles exceeding
// this range will be clipped.
// -- For angles more than 359 degrees above or below min(angle1, angle2),
// scale marks will not be drawn.
// -- If you need a counterclockwise scale, use @QwtScaleDiv::setRange (1)@
// or @QwtScaleDiv::setRange (2)@.
