Fix Tcl sample code
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
After VTK 6.0.0 has being release some of the Tcl examples does not work as expected.
This can be fixed if we add the expression
at the end of the script
I can apply the changes to all .tcl example needing that change.
What should I do to apply the changes and commit?
