[vtkusers] Extract region with vtkTracerInteractorStyleImage

[Fabian Torres]

Hie Dean.

I´m actually looking at this example

http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/Widgets/Testing/Cxx/TestImageTracerWidget.cxx?root=VTK&content-type=text/plain

I think here is how to use the classes you told me. I hope this works.

Thanks for your response.
