Mint, cinnamon: how to get cairo-dock to draw over the panel

Hi.
I'm using Mint with Cinnamon. Is it possible to have my dock draw over my panel?
It would be OK, if all windows would draw over the panel.

I think you could try wmctrl: http://linux.die.net/man/1/wmctrl
xprop might also work, bit some users seemed to had problems with setting things like always on top & other WM stuff using it.

thanks for pointing me in a direction.
However, I'm a noob, and can't figure out how to force always on top with wmctrl or xorg.
Can you give me an example?

EDIT: wmctrl -r :SELECT: -b add,above
tried that, it doesn't work. no window wants to be drawn over the panel.
