arboard advertises that it works with Wayland, but in reality it only works with Wayland terminal applications. To make the clipboard work with applications that draw Wayland surfaces, arboard isn't going to work. Copypasta does support Wayland's graphical clipboard, but the usage isn't documented. However, for the reasons mentioned in #1474 the move from Copypasta to arboard makes sense. To resolve the issue, this commit brings in an optional dependency smithay-clipboard, that is a crate that correctly handles the Wayland clipboard in graphical applications. It is used by default if a Wayland window handle is found. If for some reason the handle to the Wayland window handle cannot be fetched, arboard is used as a backup.
