Does anyone know how to create multi-page quicklook thumbnails? The 
documentation only mentions API for multi-page previews, not for 
thumbnails. However it should be possible, because the system 
generators do, e.g. for PDF (as can be seen from coverflow, as well as 
the way the curled page reveals the second page). I have tried using 
QLThumbnailRequestSetImageWithData passing PDF, but that did not 
completely failed.
