This is an OpenGL effect to replace the startup notification used by KRunner. It provides the same functionality without the need to move and shape windows and supports translucent icons. The effect registers a manager selection which is honoured by KRunner to not start the startup notification if the effect has registerd the selection. See Review Request http://reviewboard.kde.org/r/5529/ svn path=/trunk/KDE/kdebase/workspace/; revision=1186408
