no painting program?! really??

[David Jaffe]

OK, I already asked this once, but I can't believe that the answer is no.
Is there really no "painting" program for sco xenix, which would allow one
to construct drawings, diagrams, and so forth??  I am looking for such a
program which generates postscript.
