// .NAME vtkAngleRepresentation3D - represent the vtkAngleWidget
// .SECTION Description
// The vtkAngleRepresentation3D is a representation for the
// vtkAngleWidget. This representation consists of two rays and three
// vtkHandleRepresentations to place and manipulate the three points defining
// the angle representation. (Note: the three points are referred to as Point1,
// Center, and Point2, at the two end points (Point1 and Point2) and Center
// (around which the angle is measured). This particular implementation is a
// 3D representation, meaning that it draws in the overlay plane.
