// typical clipboard operations. Unlike some other platforms, data-transfer is
// an async, lazy operation. This means that even after "writing" data to the
// system clipboard, this class must still hold on to a local cache of the
// clipboard contents, since it may be read (repeatedly) by other Wayland
// clients.
//
// WaylandDataDeviceManager singleton is required to be up and running for
// WaylandClipboard to be minimally functional.
