[Question] Z-order management in Wayland

[Manuel Bachmann]

Hi Yan,

"And I am not sure whether USE_XDG_SHELL macro is enabled in current
Tizen upstream."

It is enabled by default. If you download a sufficiently recent snapshot of
Tizen Common or IVI (I recommend from 2014/06/20 so you can have Weston
1.5.0), and click on the "Minimize" button of a random EFL application, it
will in fact minimize the window with "xdg_surface_set_minimized()". It is
a good way to check if this macro was enabled.

Regards,
