[pstricks] pst-venn diagram compilation difference between xetex and latex-->dvi-->ps-->pdf

[Luis Sequeira]

I downloaded mactex 2019 and there is no difference.
However, I noted something that might help troubleshoot this.

If I do 

\begin{pspicture}(-3.2,-3.2)(3.2,3.2)
   \psVenn(-1,0.5)(0,-1)(1,0.5){1.5}{2}
\end{pspicture}

there is an error and the whole number 2 circle is painted on.
Likewise for {1} and for {3}.

But doing it with a parameter of 4,5,6 or 7 works correctly and there are not errors
on the console, for example

\begin{pspicture}(-3.2,-3.2)(3.2,3.2)
   \psVenn(-1,0.5)(0,-1)(1,0.5){1.5}{7}
\end{pspicture}

paints the center piece (the intersection of all three sets) and gives no error.
