Since commit a4dee94afed9ade6ac50237c8d99a6e49d3bebc1 Writer no longer forces drawing objects to be entirely on one page. However since there is only one SdrPage for the entire document, a drawing object dangleing off the bottom of one page will be painted again on the next page, which is clearly undesirable since Word doesn't do that (and it also destroys the nice invariant that a fly on page N never overlaps a fly on page N+1). So force the SdrPageView code to ignore the drawing object on the next page, by passing in the area of the page frame so that ViewObjectContactOfSdrObj::isPrimitiveVisible() can verify that the anchor position of the SdrObject is actually on the painted page. This requires passing in another parameter; in the usual case the DisplayInfo::maRedrawArea already contains the page frame since commit 8af09bf33291df2fb2bfbbd6e42f9bf074fcc4fc, but there are special cases in SwFrame::Retouch() and SwFlyFrameFormat::MakeGraphic() where some sub-area is passed in, which cannot be used to check the anchor.
