~emersion/kanshi#97: 
output mirroring support

I'm using wayfire, kanshi 1.4.0 on arch. The options available don't allow me to configure an output to be a mirror of another one.

Mirroring an output with the same mode should be possible already by setting the same position. For different sizes, kanshi would need https://gitlab.freedesktop.org/wlroots/wlr-protocols/-/merge_requests/116.

I do have same resolution and frequency screens, I mean same modes. If I do what you say, to use the same position, the mirroring screen shares/mirrors the wallpaper, and I can see the mouse movements on the mirroring screen, but that's all, the applications, waybar and the rest don't show up. But they do have different sizes.

On wayfire after this commit: https://github.com/WayfireWM/wayfire/commit/17da01e6f694bf62f31aae9a800e4fec137d031e

Mirroring is supported. The weird thing is that the wlsunset screen changes don't get reflected on the mirroring screen. But it does work. Bad thing is that I wan to use kanshi profiles instead.

Could this be some sort of bug somewhere?

Here it goes the output from WAYLAND_DEBUG=1 kanshi:

Which shows both outputs using the same mode. Then finally:

        output eDP-1 enable
}

So both outputs with same mode, and both at position 0,0, but only the eDP-1 is showing up stuff, while HDMI-A-4 shows the wallpaper and waybar, but it doesn't show on waybar the applications running which show on the eDP-1 output. Again, when moving the mouse, it does seem to be mirrorred, since I see the movements on both outputs, but I can see anything related to what's running on HDMI-A-4, neither its waybar...
