How do I get this working in Aquamacs? There is a preset engine, i.e.,
sequence of  typesetting steps in it:

When a relevant .tex file is open, one has to select from the Aquamacs
menu, the following, so that new option for transparency should be provided
somewhere there:

Aquamacs > Command > TeXing Options > Generate PDF
Aquamacs > Command > TeXing Options > DVI and PDF > dvips + ps2pdf

If you know something, even if just a guess or advice, I'll write to the
Aquamacs developers.
