Comment 2 for bug 696025

While the patch is correct, theorically this changes the naming wrt the counterpart functions in poppler-glib, see the upstream commit:
http://cgit.freedesktop.org/poppler/poppler/commit/?id=b257428150e2c13dcc24fd8f75e4ee2c679ab41
So renaming the functions, while ideal to match poppler-glib, would just break users of poppler-python (which will break anyway again with poppler 0.18).
