Detailed Description
       A spline with G1 continuity.

       QwtSplinePleasing is some sort of cardinal spline, with non C1
       continuous extra rules for narrow angles. It has a locality of 2.

       Note
           The algorithm is the one offered by a popular office package.

Constructor & Destructor Documentation
   QwtSplinePleasing::QwtSplinePleasing ()
       Constructor. The default setting is a non closing spline with uniform
       parametrization. ( QwtSplineParametrization::ParameterUniform ).

Member Function Documentation
   QVector< QLineF > QwtSplinePleasing::bezierControlLines (const QPolygonF &
       points) const [override],  [virtual]
       Interpolate a curve with Bezier curves. Interpolates a polygon
       piecewise with cubic Bezier curves and returns the 2 control points of
       each curve as QLineF.

       Parameters
           points Control points

       Returns
           Control points of the interpolating Bezier curves

       Implements QwtSplineInterpolating.

       Returns
           2

       Reimplemented from QwtSpline.

   QPainterPath QwtSplinePleasing::painterPath (const QPolygonF & points)
       const [override],  [virtual]
       Interpolate a curve with Bezier curves. Interpolates a polygon
       piecewise with cubic Bezier curves and returns them as QPainterPath.

       Parameters
           points Control points

       Returns
           QPainterPath Painter path, that can be rendered by QPainter

       Reimplemented from QwtSplineInterpolating.
