[vtkusers] rotation of 2D contour labels

[vtk at scil.sinp.msu.ru]

Hi!

Does anybody know, how to make labels rotate like it is done in 
labeledContours.tcl?
What really is on the air when I rotate the scene with the mouse?
What functions are called to do that?
I see, it differs from the rotation functions of normal 3D objects 
(Prop3D). But I cannot do something with labels in my prog: cannot change 
with/height and position by calling SetWidth etc.

Thanks for help!
