It's a custom operator, specific to Ghostscript, and no, it should not
be used anywhere else. I'm not sure if it only fails in SAFER, but,
frankly, don't use it. It was supposed to be removed or changed, and I
didn't realise that had not happened.

Basically, as it stands, it is behaving as expected.

Thanks, as always, for testing.
