	I do not know first hand but I hear Display Postcript gets compiled
down to machine code and is not interpreted. Also from what I have seen
of the NeXT Machine the windowing is handled in Objective C, only the actual
graphic output is in postscript. This is why display postscript blows away
everything else inlcluding NeWS in terms of speed. I'll know more when
the black boxes come rolling through the door.
