Sorry-- got sidetracked by something else. I see what you
mean. OK, so the proposal is: change the ".png" branch in
`org-babel-execute:latex' to override `org-preview-process-alist'
with something that will:

 - actually produce a PNG formatted file
 - by default, run latex more than once, tho this could of
 - course be customized
