Hi Tim,

I have applied your patch, thanks.

The header for the LaTeX files used to produce PDF export independent
from this.  The stuff here is only used to create small images that
will be displayed in Emacs or used in HTML export.

With continued thanks to Patrick Daly, the author of fullpage.sty and
my favorite LaTeX book "A Guide to LaTeX2e", I put the margin and text
size settings accomplished by fullpage.sty in org-format-latex-header
of org.el.
Org-mode version 6.30trans (release_6.30d.882.gdbd63.dirty)
The diff below is offered as a step towards inlining the
functionality.

The caveats:
1. This is untested
  - When I execute org-export-as-pdf some other header appears in
    the .tex file, and I have not yet discovered the source of this
    other header.
2. This is the first time I've done a git diff.

If there are troubles in testing I will be happy to help resolve.

Good morning,
Tim
