Part of the wayland integration as well. Wayland won't support middle-click to paste, nor will it provide the X copy buffers. This means that middle mouse paste + mark-to-copy has to be provided by toolkits, in some kind of way. That also means that the toolkits need to figure out a way to do "copy on mark" without breaking the buffer already in clipboard. I somehow doubt that middle click to paste will survive the transition to Wayland.
