gs: .setpdfwrite is deprecated
Using gs 9.52 I get the following warning while building the documentation:
**** WARNING: The .setpdfwrite operator has been deprecated and will be removed entirely
in the next release of Ghostscript. The functionality of this operator has
been reduced to increasing the size of the VM threshold. If you believe you
have a real need for this then you should replace your call to .setpdfwrite
with:
3000000 setvmthreshold
