xdvi figure rendering broken with gs 9.26

[Karl Berry]

Hi,

    https://bugs.mageia.org/show_bug.cgi?id=24941

FYI, xdvi(k) is primarily maintained by its original author,
Paul Vojta (cc'd). Upstream is http://xdvi.sourceforge.net/ ...

    xdvi figure rendering broken with gs 9.26

Your example document and figure work for me with xdvi (from tl'19) and
gs-9.26.  It's with gs-9.27 that the figure is not displayed.

This is almost certainly because gs-9.27 (which was released as we were
finalizing TL'19, so there was no chance to deal with their induced
incompatibilities) removed many operators.

I hope Paul will be able to look at it.

Thanks for the report. --karl
