[PATCH weston] Popup stacking

[Bill Spitzak]

I would greatly prefer if the demo Wayland compositor did not enforce 
"active on top". This assumption is causing endless grief, it makes drag 
& drop impossible and overlapping windows useless.

A lower window that wants a popup or transient should end up with the 
popup or transient above any higher windows. There certainly should be 
no need to "activate", and you really should not be using the word 
"activate" when "raise" is the side-effect you want.
