Add fields to a PDF?

[samzhang111]

Would it be possible to have parity between the PdfFileReader and the PdfFileWriter when it comes to form fields? Right now, it is possible to read a form field, but it isn't possible to create one through the writer. I would like to add text form fields to a static PDF through bounding boxes.

I could implement this feature if it's possible -- I just haven't read enough of the PDF spec to know whether it's difficult or not. Please advise.
