Once the pipeline has been created, it is opened in the pipeline
editor as shown and the menu bar and tool bar are updated. You may now
select filters from the menu to add. Filters are applied to the
pipeline in the order they appear in the editor. If the "Save Output"
filter is not added to the end of the pipeline, the output appears in
the console area when the pipeline is executed.
The screenshot shows a single filter called "File Selector" which
contains the files we just selected.
