Owen Densmore of Sun presented the object oriented programming tools
for NeWS (classes, etc) at the Usenix 3rd Computer Graphics Workshop
in Monterey in 1986.  The paper, which begins on page 117, includes
a complete listing of the implementation of classes in PostScript.

You can get the proceedings from Usenix, and they hold only a copyright
on the collection of papers; the ownership of the papers themselves
remains as it was.  Owen's paper is published without a copyright
notice, so it is effectively public domain.  Legalese aside, I doubt
that Sun would have included the entire implementation listing if they
didn't want you to use it, so have at it!
