Display PostScript implements a PostScript interpreter and rasterizer on
an X server, accesses the interpreter through X protocol extensions, and
is typically implemented as Adobe-supplied code grafted onto vendor X
servers (Sun and SGI have been the main vendors, HP opted not to do DPS,
and of course there's no DPS for XFree servers). An X server with DPS
can render PostScript without an external interpreter such as the
GhostScript viewer.
Gnu announced in May (http://www.gnu.org/bulletins/bull24.html) that
they're working on a Display GhostScript -- I don't know how far along
they are or how compatible it will be with traditional X-server-resident
DPS servers. I gather from the announcement that you can locate the DPS
client library (the missing DPS*.h files and associated library) in
GhostScript source distributions.
Of course, I also expect that anything Sun is implementing with DPS will
also be implemented in non-DPS ways, since they license to many vendors
(and render to X servers) that don't have DPS.
