Detailed Description
       An approximation using a basis spline.

       QwtSplineBasis approximates a set of points by a polynomials with C2
       continuity ( = first and second derivatives are equal ) at the end
       points.

       The end points of the spline do not match the original points.

Member Function Documentation
   QPainterPath QwtSplineBasis::painterPath (const QPolygonF & points) const
       [override],  [virtual]
       Approximates a polygon piecewise with cubic Bezier curves and returns
       them as QPainterPath.

       Parameters
           points Control points

       Returns
           Painter path, that can be rendered by QPainter

       Implements QwtSpline.
