qt branch: Bring back quesoglc for text drawing for now. We can then spend some more time
perfecting the Qt-based text drawing without the stress of not being able to merge this branch. git-svn-id: https://warzone2100.svn.sourceforge.net/svnroot/warzone2100/branches/qt-trunk@10868 4a71c877-e1ca-e34f-864e-861f7616d084master
