This is exactly what Inkscape recommends for including its PDF export
with TeX annotations (see also the header comment in
endofproffwd.pdf_tex). I'm not sure if such a low-effort copy-paste
one-liner should reach the median quality of CTAN or TL. Just using
\squarenwsefill from the STIX fonts would have done the trick even
without hard-coding paths or PDF colours.

MiKTeX has had a bug report for that package:
https://github.com/MiKTeX/miktex-packaging/issues/176

and Karl imported the fix into TL with -r55063
http://tug.org/svn/texlive?view=revision&revision=55063

I still wonder if this was tested at all on our side. The fix made it a
little better, but still left the package in a broken state. Hard-coded
relative (!) path names to (mistyped!) subdirectories, and integral
parts of the package mistaken as documentation … red flags, IMHO.

This is not (only) a TL problem in the first place, it's a case for
CTAN. It has been broken since its inclusion into any TeX distribution.
