/**
* Unfortunately we have some problems with processing more than one Paint()
* at a time. This happens especially often during printing.
*
* SwRootFrame::PaintSwFrame() determines that it's called a second time and adds the
* rectangle and the corresponding Shell to the PaintCollector.
* The call sites that are causing the double Paint() only need to process the
* collected Paint()s at the right point in time.
* Doing this during printing (after having printed one page) is very suitable
* for doing that.
*
* Invalidating windows directly from the RootFrame::PaintSwFrame was not a successful
* approach, because the Paint()s arrive at a very unfavourable point in time.
* Triggering an update for all windows after printing each page does not seem
* appropriate either: on the one hand we don't have direct access to the edit
* windows and on the other hand the updates can become very costly on some
* platforms.
