Including graphics when converting from tex to docx

[petobens]

I have three questions regarding converting .tex files with images to .docx files:

Consider the following foo.tex file:

\documentclass{article}
\usepackage{graphicx}
\graphicspath{{figures/}{tables/}}
\usepackage{floatrow}
\begin{document}
\begin{figure}[!htb]
  \includegraphics[scale=1]{foo.png}
  \caption{Foo plot}
\end{figure}
\end{document}

where figures/foo.png is just a black square (and figures/ is a subdirectory inside the directory where foo.tex lives). This produces the following pdf:

i)

If I run pandoc -s foo.tex -o foo.docx I get the following error:

pandoc: Could not find image 'foo.png', skipping ...

Apparently pandoc cannot parse the \graphicspath command from the graphicx package. Is it possible to add support for this?

ii) Assume now that pandoc actually finds the foo.png file. The floatrow package (among other things) centers floats automatically. However, when the foo.tex is converted the figure in the .docx file is not centered:

iii) Finally: is it possible to include pdf figure files? I guess not (according to #2381 and #2350).

Thanks in advance for your help and sorry for asking too many questions.

Closing in favor of #736 re graphicspath.

We should be able to handle this more smoothly after architectural changes for pandoc 2.0 (current typeclass branch).
