top and bottom automatically gradient bevels according to the color scheme. Very cool looking, and no configuration required. If you want to see a pic look at http://www.mosfet.org/system-gr.gif. To try it out update, set the system color scheme, and the switch to the System style via the right mouse menu on the kwin titlebar. svn path=/trunk/kdebase/kwin/; revision=39064
