 In KDE it's a property of the panel (I fail to see why anybody would want the 
panels not to be on the top, if if they do, they may want it only for some of 
them). Right now the on_top/not_on_top panels are TYPE_DOCK+STAYS_ON_TOP vs 
TYPE_DOCK, but I wouldn't mind having them as TYPE_DOCK vs 
TYPE_DOCK+STAYS_BELOW (which is more logical) or whatever.

 Well this is almost the same as I wrote above. I'd just move TOP above DOCK, 
as that's what users would probably expect.
