// .NAME vtkPVAxesActor - a 3D axes representation
// .SECTION Description
// 
// vtkPVAxesActor is used to represent 3D axes in the scene. The user can
// define the geometry to use for the shaft and the tip, and the user can
// set the text for the three axes. The text will follow the camera.
//
// VSR 03/12/2014: the original file vtkPVAxesActor.h has been renamed to salomevtkPVAxesActor.h
// to avoid collisions with native VTK/ParaView classes
