SysV/386 Graphics Packages?

[Gil Kloepfer Jr.]

A company I work for is considering the purchase of a 386-based PC running
AT&T System V UNIX for development of a graphics-based application.  The
system we are considering will have either an EGA or VGA graphics adaptor
and monitor.

Does anyone out there have experience using particular graphics programming
libraries that work in this hardware environment?  How portable is this
package to other UNIX environments (does the company support a wide
variety of hardware platforms?)?  Finally, does the package have additional
device-independent support for mice, digitizing tables, and plotters, all
of which will be important for our application.

I've been looking into DI-3000 from Precision Visuals, but I've heard they
are expensive and don't necessarily support the hardware we are considering.
I haven't heard back from them directly yet.

The packages from GSS sound good, but on the 3B1 I used, they were terribly
slow and more tailored for FORTRAN IV than for C programming.  Has GSS
changed their face yet?

Of course, X windows sounds interesting, but I only know a little about
it, and have heard that there's still bugs in the version for the SysV/386.
Does anyone know better?

Thanks in advance for any information!
