[OS X Emacs] problems: LaTeX + dvips+ps2pdf

[Roussanka Loukanova]

Dear All, Dear Win,

I've upgraded to TeX Live 2021. I'll appreciate help for typesetting .tex
files that require pstricks via Aquamacs.

These files used to be typeset finely with:

- latex->dvips->ps2pdf, up to some point of TeX Live 2020 (Autumn)
- XeLaTeX in the latest TeX Live 2020

Now, with TeX Live 2021, neither of these engines work in Aquamacs. It
seems the commands require new options for Ghostscript 9.53.3.

The following commands work finely from the command line of Terminal, with
the options:

- latex > dvips (from Aquamacs and from Terminal)
Then:
$ ps2pdf -dALLOWPSTRANSPARENCY test-file.ps

If I open the test-file.pdf with Skim it's properly typeset. But Aquamacs
can't display the pdf, via Ctrl-c Ctrl-v from the .tex: it replies no
default viewer.

- XeLaTeX in Terminal:
$ xelatex -output-driver="xdvipdfmx -i dvipdfmx-unsafe.cfg -q -E"
test-file.tex

Aquamacs displays the correct pdf, via Ctrl-c Ctrl-v from the test-file.tex

But I do not know, any longer with the newer versions, how to set them in
AucTeX in Aquamacs.

If somebody knows how to get how to set the necessary commands in Aquamacs
/ AucTeX, I'll appreciate instructions, very much.

For information: I can typeset files requiring pstricks finely in TeXShop,
by special engines for GhostscriptTransparency written by Herbert Schulz
for TeXShop.

Best Regards,
Roussanka
