I got into the iText codebase and realized that when setAppearance is
invoked on the PdfAnnotation object, internally, the logic checks for the
existence of the AP key in a dictionary and if not present, it generates all
the reqd stuff ....so, setAppearance seems to be doing whatever is
required...only thing is why it doesn't work on DOWN, whereas it works on
NORMAL... could this possibly be a bug in case of the screen annotation?
