Just a draft.
I have to provide a new PostScript header (mypst.pro) which forks the definition of feather (no. 94) and replaces original fill path operation with gsave <setting color> stroke grestore fill (first stroke then fill) to give an outline effect.
I don't know why setting \psset{linecolor=...,fillcolor=...,...} in \mypsvectorian doesn't work. Thus <setting color> is hard-coded by 0 setgray in mypst.pro, by now.
