[vtkusers] How to get rid of the Generic Warning

[tguo at imaging.robarts.ca]

Hello everyone,

I recently updated my VTK to the version of 5.0. Everything is fine except
that when I got this Generic Warning: In
/data/***/VTK/Filtering/vtkViewport.cxx, line 783
vtkViewport::GetProps was deprecated for VTK 5.0 and will be removed in a
future version.  Use vtkViewport::GetViewProps instead.

It's annoying, since this warning constantly occupies the command window.
How can I get rid of it?

Thank you very much for your help.
