At the NeXT day developer's conference, I was among a group of people who
were all trying to get specifics about the Display PostScript implementation
from Leo Hourvitz, who had just given a talk on the NeXT windowing system.
He said that there is no anti-aliasing in their implementation, and that
it would be a very difficult problem to do this with PostScript.  He also
implied that you wouldn't get much improvement with only a 2 bit gray scale.
