halftone newsprint offset inkscape vectors

I saw something on a THERE (ad agency) website and started to wonder how to do halftone in vectors. Of course for bitmaps, there's a filter for it ( gimp/filter/distort/newsprint ), but it never came up as something to want in vectors until now. After a bit of googling and some failed attempts I made sense of it, via http://istarlome.deviantart.com/art/halftone-effect-in-inkscape-85648573 . The solution was hiding in a place that is not quite intuitive but sometimes such is live ( inkscape/edit/clone/createtiledclone/trace )
