Subject: [PATCH] Bug 699744 "ps2epsi fails with Error: /undefined in
--setpagedevice--"
Recent changes required to harden SAFER mode mean that it is no longer
possible to run this script in SAFER mode, because it relies upon
unsafe Ghostscript non-standard extension operators.
Removing SAFER and DELAYSAFER, and the code to reset SAFER, allow the
program to run as well as it ever did (ie badly). This program should
now be considered unsafe, you should not use it on untrusted PostScript
programs.
I think its likely we will deprecate and remove this program in future.
