I may be misremembering, but this may not work correctly. IIRC the 
window placement algorithms require the window's viewport to be current 
when they're called (so that they don't need to care about the 
translation added by the viewports)

no, that sounds correct. It's definitely true that you can't rely on 
the order in which they are invoked.
