              This is a very interesting one off PDF that shows an implementation issue with how we handle the saving of a graphic state before we process a form and after. The issue is that when we set the save/restore we are doing the same function as a regular q/Q. I think this is incorrect, what we really want is to save the graphics state in it's entirety and restore it after the forms is processed, very similar to what we do when working with the Java2D Graphics object.

              The assumption seems to hold water and the PDF now renders correctly.

              It turns out the water mark cm transformation is what was exposing the rotation issue and bug in our form handling. PDF renders correctly now.
