            Description

            As we need to store annotations seperatly we use the IncrementalUpdater to extract the annotations. Unfortunatly when all annotations of a document are deleted there will be still annotation information provided by the IncrementalUpdater. Cause of that we are not able to know when every once made annotation of a document is deleted and the document is free from annotations again.

            This is how it looks after some text and popup annotations are deleted:

              Thanks for the feedback Stephan, cleanup should be possible with the exception of the page object but I'll see what can be done.

              I've update the Page class to try and clean up an annotations resources. In particular the cleanup of a TextAnnotation's font resource. The clean up should only happen for font that we have created as we can guarantee the font won't be used anywhere else.
