ob-latex: New custom option `org-babel-latex-process-alist'
* lisp/ob-latex.el (org-babel-latex-process-alist): New variable.
(org-babel-execute:latex): Override `org-preview-latex-process-alist'
when generating png output, making sure that the process yields an
actual png image, even when `org-preview-latex-default-process' is
non-default.
* etc/ORG-NEWS (=ob-latex= now uses a new option
~org-babel-latex-process-alist~ to generate png output): Announce the
change.
