[vtkusers] Got an vtkActor and a Matrix4x4, want to copy the vtkActor and apply a tranformation with this matrix

[Maxim Schäfner]

Hello,

I have a problem with VTK.
I have a method which gives me an vtkActor and a vtkMatrix4x4. I want to 
copy this Actor and apply a transformation, with this matrix. But this 
transformation doesn't work. An normal RotateX-call etc works, but the 
transformation don't, why? What I have to do, when I want to get 1:1 
copy of the Actor, though I can change the properies of it, without the 
change will apply to the original Actor, too?

Thanks, for any suggestions.
