[vtkusers] ​ Rotate the vector along the X, Y, Z axes.

[Andrew Maclean]

If you look at https://www.vtk.org/doc/nightly/html/classvtkActor.html you
will see that vtkActor  inherits from the abstract class vtkProp3d:
https://www.vtk.org/doc/nightly/html/classvtkProp3D.html so all the public
member functions defined here are available.

This should get you going:
//---------------------------------------------------------------
#include <vtkActor.h>
#include <vtkMatrix4x4.h>



  // Set up your actor
  vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
  // ...

  // Here's how to set the orientation of the actor.
  actor->RotateX(12);
  actor->RotateY(2);
  actor->RotateZ(-13);
  // Here's how to get the rotation matrix etc.
  vtkSmartPointer<vtkMatrix4x4> m = vtkSmartPointer<vtkMatrix4x4>::New();
  actor->GetMatrix(m);
  double * orient;
  orient = actor->GetOrientationWXYZ();
//---------------------------------------------------------------

I'll add an example to VTK Examples

> There are angles, but it is not possible to calculate the rotation matrix?
