[AUCTeX] graphicspath as a File variable ?

[Julien Cubizolles]

Is is possible to define a graphicspath in the File Variables comments
of a LaTeX file ?

I'm trying to compile just a region in chapter.tex that is imported
(through the import package) into a master file (defined as such in the
File Variagles of chapter.tex). I can't define the graphicspath in the
master file (definition not passed to the imported files) nor in the
chapter.tex file because it doesn't have a preamble...
