EbookViewer.pos

Hello, everyone.

I am attempting to add a feature into the Calibre viewer that will allow users to see their position in a chapter.

To do this, I need to know where the EbookViewer.pos attribute is assigned, or the class it represents.

Thanks in advance.

PS - To the Calibre developers: thank you for making _the_ best PC eBook utility out there.
