Awesome, Andreas!
If you don't object, I'll add Mr Tiger as a Rendering test case.

That shouldn't be a problem, as it is a part of Apache FOP. Jeremias and I had discussed that issue one year ago [1] and finally I found the solution...

[jira] Resolved: (PDFBOX-646) Map the form space to user space if
hte optional form matrix is present

Andreas Lehmkühler resolved PDFBOX-646.
---------------------------------------
Resolution: Fixed
With version 918150 I've added a getter for the optional form matrix of an XObjectForm. Whenever a XObjectForm has a form matrix it will be took into amount within the Invoke operator by multiplying it with the current transformation matrix.
Now the attached example works like a charm with the PDFReader.

That file has an optional form matrix. The tiger doesn't show up using the PDFReader.
Jeremias provided me with that example long time ago. It's from the Apache FOP project.
