Exactly, LZWDecode would be great in pdftops; do you imply there's a way 
to do that with pdftops?  Using pdftocairo is not possible because of 
other issues with fonts...

Also, I noticed https://bugs.freedesktop.org/show_bug.cgi?id=81760 
mentions that LZW was implemented in xpdf and may be eventually merged 
back to poppler, any news on that front?
