Hehehe, you really do promote that kickoff-qml quite well! I see it so
often on your blog and other areas.

But how can i apply "my magic" to that? As you see in the example code,
I've sliced the panel in two parts. one is the 2 pixel top line and the
rest is the gradient. As far as i know the plasma theming stuff only has 1
image for the panel right? Thus i can't interrupt the border that is on top
of the panel..
