Wayland cut/copy/paste better than in X11?

[Jiergir Ogoerg]

Thanks, hopefully they'll review your patch soon since these features are
important on the desktop and since they plan to move Gnome to Wayland by H1
2014 your work should land and get tested in Wayland asap and get
implemented in toolkit(s) upstream in time before 2014.
