[vtkusers] How to display a bouding box around a dataset?

[Sebastien Jourdain]

The reason for that is because you did not add any mapper/actor on the
dataset itself. The outline filter is a filter in the sense that it
take a dataset as input and give a wire box as the output. So if you
want to see your dataset, you have to add it to the renderer with the
help of a mapper/actor.
