The user may request to have the thumbnail recreated even though the
thumbnail is valid and exists in the desired size. This may be
necessary if for example an application created a broken thumbnail.
This could have happened due to a broken image loader. If we don't
give the user a chance to recreate the thumbnail, there would be no
way to replace the broken thumbnail with a good one. That's why GIMP
allows the user to explicitely recreate a thumbnail even though it
appears to be uptodate.
