C/C++ API to set screen for a window on Wayland

[Viet Dang]

Hi Aleix,

Maybe my post wasn't clear, this is for multi-screen/multi-monitor setup,
so for example I need to set the dock to screen 1 or screen 2 etc.

I've already used layer-shell to set the dock's anchor, strut, and
layer, but it doesn't seem to support setting screen/monitor?

Thanks,
Viet
