Thanks for the patch.  It looks good.  Feel free to push.

* Aside 1

Re ‘org-preview-latex-process-alist’.

- It should be "you need to install the programs:..."
- :post-clean, it should consider ‘org-latex-logfiles-extensions’
- Note that you haven’t documented "%f" in the :latex-compiler.

* Aside 2

IMO the Correctᵀᴹ approach would be for Org to use the latex processor
specified by the document, when present.

E.g. \mathbb{1} typically requires unicode-math and hence requires
compilation with xelatex or lualatex.

Some things speak against this.

- :image-input-type would be "unpredictable" in the case of dvisvgm (dvi
  vs xdv), but both formats are supported.
- dvipng does not work with xelatex as it only support dvi up to format 2.

Thanks,
Rasmus
