Some of the classes/methods in the rendering area assume they have access to a Graphics2D object.
This assumption breaks when using the .Net version of PDFBox. Some judicious refactoring permits PageDrawer to be extended in .Net and key methods to be overriden.
I am continuing this refactoring for better rendering support in .Net.
Andreas recently asked that code committed to SVN also be tied to a Jira issue – a good idea really – so I'm putting this in as an issue.
