// .NAME vtkArcSource - create an arc between two end points
// .SECTION Description
// vtkArcSource is a source object that creates an arc defined by two
// endpoints and a center. The number of segments composing the polyline
// is controlled by setting the object resolution.
// Alternatively, one can use a better API (that does not allow for
// inconsistent nor ambiguous inputs), using a starting point, a normal,
// and an angle. The default API being the original one, in order to use
// the improved API, one must switch the UseNormalAndAngle flag to TRUE.
// The development of an improved, consistent API (based on point, normal,
// and angle) was supported by CEA/DIF - Commissariat a l'Energie Atomique,
// Centre DAM Ile-De-France, BP12, F-91297 Arpajon, France, and implemented
// by Philippe Pebay, Kitware SAS 2012.
