Alhough I didn't think well before, now I think Jean's contribution of
.ini code related to this topic is big enough to need to get copyright
assignment.  Here is the diff in preview.el.in with respect to his
contribution:

I already asked him and he answered that he is fine with giving over his
copyright, so could you please provide him instructions of necessary
procedure?
