Wayland itself doesn't have a way to set a global position of a window. This is because it was made with the idea that a screen could have arbitrary shapes. Some compositors do provide an extension to set the global position, but this is not something you can depend on. It also doesn't make much sense for tiling compositors I think.

This is useful functionality, and the code quality and comments look good.

A shame about the limited functionality on some platforms, but I think that supporting this on the platforms that do allow it is a clear improvement.

Looks good to me. I just pushed a change that sets the position immediately on construction. This prevents the value from being None on the first schedule run.

I still included Option because some platforms don't support window position.

Although actually we could just treat that as 0,0 and call it a day. That would make the api easier to consume. Feel free to follow up if you're interested 😄
