[vtkusers] Updating VTK

[Michnay Balázs]

Thanks Amy for the quick reply. My VTK version must some kind of 
an "early development" version, because
imageactor->SetPosition(...);
still says that SetPosition is an unknown identifier.
How can I update my VTK release? I think I have the VTK 4.2 (Windows 
binary) uploaded to the vtk.org website.
Should I use a different release? I hope I don't need to compile the 
whole VTK source code.
Thanks,

 MB
