[vtkusers] turn on/off a filter in pipeline

[Charles Boivin]

Hi Isabelle,

Some other, more experienced, users might have some better
suggestions, but an easy way is to simply skip the filter in the
pipeline when you turn it off, i.e.

rescaleFilter->setInput( adaptor );

and re-insert the logFilter in the pipeline when you want it. I do
something similar to that sometimes in my application, and it seems to
work fine. I'd be interested in knowing if there are more elegant
solutions, however.
