What do you mean? `org-create-formula-image' is passed a string of LaTeX
code. Note that `org-create-formula-image' is also used in HTML export.

ob-latex does not have to expose all the possible toggles
`org-latex-pdf-process' has.

We can fix the parameters we do not want to expose.

My concern about your patch is that it creates even more divergence
between different branches of code in `org-babel-execute:latex'.
With the new proposed features only available to some code branches,
`org-babel-execute:latex' will just become more messy and harder to
maintain.

I'd prefer to refactor `org-babel-execute:latex' first, before adding
new header arguments.
