Well, guess what, folks: xwd DOES support this already.  It's
an undocumented feature.  As asente@decwrl.dec.com (Paul Asente) writes:
>Try

It works!  The manual page we've got came off the R4 tape.  It's first line
is: 
     .TH XWD 1 "Release 4" "X Version 11"
and a grep for "id" comes up empty.
