Redaction: Adjust offset for multiple Calc pages

* Add an enum and some methods to DocumentToGraphicRenderer
to differentiate between the doc/module types:
isWriter(), isCalc(), isImpress()
* Put some checks for module/doc type
* The result seems ok for a Calc document of multiple sheets
with hundreds of pages
