browse orphan objects?

[ousia]

@brendandahl,

many thanks for your work with the browser. It is really helpful to inspect PDF documents.

This PDF document contains some orphan objects (objects with no parent, not referenced in any way [numbers 7, 18, 22, 26, 30, 34, 37 and 38]).

I wonder whether the PDF browser could also display orphan objects and their contents.

As an additional suggestion, maybe it would make sense (to search for object numbers) to be able to expand and collapse the whole object tree.

Many thanks for your help.
