Display contents faster, waste less memory. Added preloading to forward- generate pages (if threading enabled and memory profile >= normal). Main pages are always generated first, then thumbnails come, then preload ones, etc.. Btw memory and cpu will be happier now. (1 bug in memory and 1 in preloading still remains.. will be spotted soon) For Developers: Generator: dropped moc, api changes, better functions naming. PDFGenerator and Document: moved requests queue to the Document. The generator performs only a single request a time. A flag can be queried to know if the generator is ready for starting another pixmap generation or not (in case it's generating a pixmap in background). PixmapRequest: added priority and backgound (async) attributes. Document: queuing requests by priority in requestPixmaps. Observer: added defines for priorities used in doc->requestpixmaps. PageView: delayed find-ahead timer creation (not created if not needed). Added preload PixmapRequests to the pixmap requests list. ThumbnailsList: adapted to pixmapRequest changes and changed naming for delayed thumbanils request. svn path=/trunk/kdegraphics/kpdf/; revision=379820
