* Fix display of bold text. This got broken sometime in the KDE 3.x series I think.
* Enable Qt 4 double buffering to eliminate flickering * Performance improvements by drawing text in chunks (split up by appearence) rather than by character. Also cut down number of calls to QPainter::eraseRect(). Tested with Vim , cgdb and a few colour charts. Background images and tints are still not working yet - more to do on that. svn path=/trunk/KDE/kdebase/apps/konsole/; revision=565268
