      Description

      I am missing a feature where I easily can get points along a path given a percentage.

      Similar functionality is available in QPainterPath of the Qt-toolkit:
      http://qt-project.org/doc/qt-4.8/qpainterpath.html#percentAtLength
      http://qt-project.org/doc/qt-4.8/qpainterpath.html#pointAtPercent

      The Qt-implementation has a drawback since the step length along the path is not necessarily constant for a given percentage when the path contains several segments.
