[vtkusers] rotating a 2D actor

[Kalpathi Subramanian]

Pankaj:

There is no transformation matrix associated with 2D actors and hence 
you cannot transform it (like rotate).. if you
need to transform your objects use vtkActor.  Tell us what object you 
need to rotate in your app and we might be
able to offer suggestions.  (again, read the vtk doc for vtkAcor2D you 
will see this in the description).
