Avoid changing anchor on visibility change of cell

This is an addition to commit 1f0b3c7a40edfa81bbc7a58d123a6a2dfd83e4ca
The following scenario had produced a wrong object size: The object is
anchored to cell. Some columns containing this cell were hidden and
then shown again.
ScDrawLayer::SetCellAnchoredFromPosition was called in this case and
had produced the wrong size. When the column of the object anchor is
shown, object becomes visible. This gives an 'object change' event,
sent to ScDrawView::Notify, which calls adjustAnchoredPosition. That
had a test pAnchor->getShapeRect() == pObj->GetSnapRect() that should
prevent calling SetCellAnchoredFromPosition. But exact equality fails
due to +-1 differencies because of Twips<->Hmm conversions.
