After some trial and error I have figured out that GlobalParams does
work but it must be called after reading the document. If I first call
new GlobalParams(path.c_str()) and then document::load_from_raw_data()
it does not work. But if I first call GlobalParams, then load the
document, and then get the text, it uses the poppler_data as specified
in path.c_str().

Not sure if this is intended but I can make it work now.
