 * @class   vtkEllipseArcSource
 * @brief   create an elliptical arc
 *
 *
 * vtkEllipseArcSource is a source object that creates an elliptical arc
 * defined by a normal, a center and the major radius vector.
 * You can define an angle to draw only a section of the ellipse. The number of
 * segments composing the polyline is controlled by setting the object
 * resolution.
