Subject: [PATCH] org.el (org-format-latex-header): put DEFAULT-PACKAGES before
 PACKAGES

* lisp/org.el (org-format-latex-header): put DEFAULT-PACKAGES before
PACKAGES, as per org-latex-packages-alist's documentation.

`org-format-latex-header' is mostly used to generate in-buffer images
from LaTeX fragments. For LaTeX document export, the header is
generated by `org-splice-latex-header' ond `org-latex-classes' instead
and the default and documented behaviour is to insert DEFAULT-PACKAGES
before PACKAGES.
