That works; I was thinking of taking it over to the renderer (since the
definition of the style is separate from how we are using it).
FilterFactory ff = CommonFactoryFinder.getFilterFactory(new
Hints(Hints.LOOSE_BBOX, true));
DuplicatorFilterVisitor copy = new DuplicatorFilterVisitor( ff );
And then for each filter used:
filter.accepts( visitor );
filter = visitor.getCopy();
