Whether to show text content that is marked as an artifact.
By default all text is returned, including text that may not be
relevant to the user because it is tagged as an artifact. In cases
where you are extracting text you may wish to ignore artifacts
since, by definition, they are irrelevant. In cases where you are
changing text you typically want to include artifacts as, while
they offer no semantic information, they still have an appearance
that may need updating.
Using this setting you control whether you want this text
returned by GetText.
