Dear Tim, Your description of how "prepareLayout" works seems to be
somewhat accurate, in my opinion. IMHO, the problem is that
DocumentView::prepareView assumes that for a given current page, the
pages between DocumentLayout::leftIndex and DocumentLayout::rightIndex
are visible and that these intervals do not overlap, i.e. any given page
is visible for exactly one current page.  Hence what you describe will
be difficult to accomplish without increasing the separate of concerns
between DocumentLayout and DocumentView further.  (DocumetLayout is a
post-facto refactoring that removes some but not all of DocumentView's
code related to layout, but it is not a solid solution.)read more here
