\class QPdfFile

QPdfFile is a means of passing a PDF file along with the associated
QPdfDocument together into QPdfIOHandler::load(QIODevice *device) so that
QPdfIOHandler does not need to construct its own redundant QPdfDocument
instance. If it succeeds in casting the QIODevice to a QPdfFile, it is
expected to use the QPdfDocument operations for all I/O, and thus the
normal QFile I/O functions are not needed for that use case.

// Give up thread affinity: it may be created in one thread, rendered in
// another, and deleted in another. The rendering thread needs to be able
// to "pull" the affinity to itself. If deleteLater() is used, then
// the affinity _must_ be changed to avoid a memory leak!
