/**
* Adds a checkbox labelled "Preview" for "automatic" preview. The reference to this checkbox can
* be retrieved by getPreviewCheckbox() and it provides the additional method previewRunning for
* optical feedback while preview is prepared. PlugInFilters can have their "run" method
* automatically called for preview under the following conditions: - the PlugInFilter must pass a
* reference to itself (i.e., "this") as an argument to the AddPreviewCheckbox - it must implement
* the DialogListener interface and set the filter parameters in the dialogItemChanged method. -
* it must have DIALOG and PREVIEW set in its flags. A previewCheckbox is always off when the
* filter is started and does not get recorded by the Macro Recorder.
*
* @param pfr A reference to the PlugInFilterRunner calling the PlugInFilter if automatic preview
* is desired, null otherwise.
