thanks for the pointer. I was not aware of the adjustbox package
before. Definitely interesting.
Playing with it I found the flaw in my patch. The inclusion of
[[foo.tikz]] is wrapped in \begin{tikzpicture} ... \end{tikzpicture}
already during LaTeX export.
So, exporting my example to latex gives a nested tikzpicture. There is
nothing wrong with that, but the outer tikzpicture has these scaling
options, hence the wrong placement/scaling.
The code block that is going to tikz should, thus, *not* contain
the \begin{tikzpicture} and \end{tikzpicture} directives.
That might not render my patch completely useless, but limits its
use at least.
I was hoping for one and the same latex code block to be evaluated to
tikz/pdf/svg/imagemagick giving (more ore less) the same resulting image
in each.
In the moment that is not the case.
To clarify this:
--8<---------------cut here---------------start------------->8---
# can be evaluated to tikz (to export to latex)
#+begin_src latex
<<picturecontents>>
#+end_src
# can be evaluated to pdf/svg/imagemagick
#+begin_src latex
\begin{tikzpicture}
<<picturecontents>>
\end{tikzpicture}
#+end_src
--8<---------------cut here---------------end--------------->8---

Andreas
