Thanks, It's now requiring org-exp and org-latex.

in newer Emacs C-- and C-+ should be usable to adjust the font sizes.

hmm, this uses the same machinery used to display latex previews in
regular Org-mode buffers (callable with C-c C-x C-l), so if that works
this should work, and vice versa, but I believe this does require some
special commands be available on your system (e.g. dvipng).
