Hmm that may be the function I am looking for but I don't understand
where I should pass a GlobalParams object when reading a pdf file. I
tried setting the 'globalParams' global when loading the R package but
that doesn't seem to work:

   globalParams = new GlobalParams(path.c_str());

Should I be passing the path to the "share" path or the
"share/poppler" path? FWIW our bindings are quite simple wrappers for
the cpp api: https://github.com/ropensci/pdftools/blob/master/src/bindings.cpp
