 Ah, I see (there's a difference between 'dialog' and 'child window').

 Following either WM_CLIENT_LEADER or WM_TRANSIENT_FOR hints should probably 
solve this. A couple of lines in KWin could handle that.

 There are definitely going to be people or cases where it won't fit, so it 
shouldn't be hardcoded (e.g. if I put a toolbar at the screen edge, I guess 
I'd yell if it moved together with the window - not that _I_ actually move 
windows much when I maximize them all anyway ... maybe I should implement a 
new KWin placement policy called 'maximize' ;)  ).
