I have no warranted crystal ball (but if you know the ftp site ... ;-)

It is my understanding that ANSI is once more interested in this
topic. They are expected to put it to ISO in a position paper or
sugested addendum.

Yes, it has supported double buffering for a number of years

dunno
Applying a cell array to uv parameter space for NURBS might be one option...

The Evans&Sutherland implementation has had antialiasing for a while.
The DEC implementation supports it only on harware that supports it.
Both do it as escapes. There is no support for antialiasing in the ISO
standard.

I will comment on OpenGL once an implementation has actually been
released. In the mean time, I will continue using PHIGS and PEX, as I
cannot program with promises.

>Finally, a different question. Is PEXIM publicly available (ftp'able)?
>And if it is, then where?

Yes I believe so. Try archie
