Fyi I'm currently working on pushing this over the line. I've already completely ported all input over to xinput2/xkb and validated that ad-hoc keyboard layout changes, multiple seats, etc. work...

Fyi in https://github.com/maroider/winit/pull/6 I've added a platform extension that allows the XInput id to be retrieved from DeviceId.

PS: I've noticed that winit never destroys any wayland surfaces. I've kept it that way with the new objects I've added.

>@mahkoh winit should destroy the surface via sctk iirc, unless sctk changed that? I don't believe this applies to the wl_surface itself.

Please go ahead. I'll add destructor calls for the new objects I've added in this PR.

`self.surface` refers to an xdg_surface not to a wl_surface.

Keep in mind that the wl_surface must be destroyed after the xdg_surface. Otherwise a protocol error occurs.
