You can now do (I think)

#+BIND: org-export-latex-image-default-option "width=1cm"

This will work for any variables that are not addressed by
#+OPTIONS and similar lines.  It will not work for anything
that is in `org-export-plist-vars', and that is confusing.
Any ideas on how these should interact?
