that sometimes disappeared in regressions related to annotation CTM problems in the last few
months.)

> The way in which PDFBox handles the Page tree needs to be rewritten, preferably from
scratch. Currently the document catalog returns the raw objects from the page tree, wrapped
in either a PDPage or PDPageNode.
> We need to abstract over the page tree and get rid of PDPageNode, we should provide methods
which can add/remove PDPage objects *only*. The existing low-level access to the page tree
is not needed at the PD-level.
> Inheritance of page properties such as crop box, resources, and rotation should be reimplemented
to use whatever new page tree abstraction we invent. We can finally remove the old broken
methods which didn't look up the inheritance tree when retrieving these values.
