Making this style ultra-cool ;-) If you are on a highcolor display the frame

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.
