`org-latex-preview-process' is a good idea, which make org-latex
beginner easily, i will add it.

I suggest to add (:generator my-generator-function) style configure
to `org-latex-pdf-process', it is simple and powerful feature, we
can use this feature to switch latex commands dynamicially, for example:

(defun my-latex-pdf-process-generator (texfile snippet extra-info)
   ((<a>) (<org-latex-pdf-process-style-command1>)
   ((<b>) (<org-latex-pdf-process-style-command2>)))))

although we can set org-latex-pdf-process to a function to do the same work,
but this function is hard to write as org-latex-compile, it may only
useful for developer instead of user....

caller-info argument is for the above feature.

Remove the above two and only use the below *one* ?

 "Set `org-latex-preview-ltximg-directory' instead." "25.1")
