Avoid infinite loop when loading huge filesHEADdev
QTextDocumentLayout could get into an infinite loop when the contents exceeded QFIXED_MAX. Specifically, QFIXED_MAX is used as meaning "one infinite page" which means that newPage() will just return when it sees this page height. If the page actually grew larger than this, though, we would treat it as a page break and enter a loop where we try to call newPage() to create new pages and never return. The layout engine cannot support documents this large, so we detect the case and then just finish the layout loop early when it is encountered.
