[pstricks] pstricks and color revisited (with xypic)

[Jonny Smith]

Yes, this works.

Yes, the "&" characters stemmed from some obsolete array env and were
needless. My bad..

There is one more thing that concerns me:

If I try to change the position of the gradient by means of say

\begin{pspicture}(-2.5,-1.25)(2.5,1.25)
  \psellipse[gradbegin=blue,GradientScale=2,GradientPos={(-2,-1)}](2.5,1.25)
\end{pspicture}

...

\xy (0,-20)*+<1.5pt>[<40pt>]{
        \begin{pspicture}(-2.5,-1.25)(2.5,1.25)
          \psellipse[gradbegin=blue,GradientScale=2,GradientPos={(2,-.5)}](
2.5,1.25)
        \end{pspicture}
        \begin{pspicture}(3,4)

\pspolygon[gradbegin=black,GradientPos={(-.1,-.1)},GradientScale=2](0,0)(1,3)(3,2)(
1.5,2)(2,0.5)
        \end{pspicture}
};

within this file it has no effect whatsoever. Is there some option missing?

Thanks,

J
