Is there any simple way to make filefilter pattern (provided with 'void add_pattern (const Glib::ustring& pattern)') case insensitive?

taking an arbitrary regular expression and using it for non-case
sensitive-matching is non-trivial. if you want this, just use a
suitable regular expression, otherwise, you're asking for a more
powerful regular expression engine than i believe glib offers. i could
be wrong.
