[Question] Z-order management in Wayland

[Tanibata, Nobuhiko (ADITJ/SWG)]

Yan, 

No way to change order of top-level surfaces in current Wayland
protocol.
If you want to do it, you can extend protocol by yourself and implement
own shell loaded on Weston.

One example is http://projects.genivi.org/wayland-ivi-extension/.
There is a similar use case in In-vehicle Infotainment system regarding
consumption of power.
