Yes, you are right....

Actually, when playing around with it, I observed two issues:
- negative radius: does not seem to have any effect?
- when pressing "Defaults", the view is not updated.

To come back to the originial question: For adding vignette,
could this be realized by extending the range of any of the sliders
(e.g. a negative density?) or do we need a checkbox
for this "inverted" purpose?

Unless there is a way to add vignette in some way,
could you please file a new wish in the bug-tracker so
that it is not forgotten?
