=========
Consider features that make it easier to detect certain patterns in
PDF files. The information below could be computed using an external
program that reads the existing json, but if it's useful enough, we
could add it directly to the json output.
* Add to "pages" in the json:
* "inheritsresources": bool; whether there are any inherited
attributes from ancestor page tree nodes
* "sharedresources": a list of indirect objects that are
"/Resources" dictionaries or "XObject" resource dictionary subkeys
of either the page itself or of any form XObject referenced by the
page.
* Add to "objectinfo" in json: "directpagerefcount": the number of
pages that directly reference this object (i.e., you can find an
indirect reference to the object in the page dictionary without
traversing over any indirect objects)
