title: Update Widgets in PDF using Podofo
body: <p>I am using PdfAnnotation.SetContents to set the value of an annotation.If the annotation is of type FreeText, only then this method correctly works and the value gets displayed on the PDF (using PDF Reader).If the type is Widget, the value gets set as content in pdf dictionary but does not get displayed.Is there a way i could set the value of a widget?</p>
