[webkit-gtk] can be modified in this way?

[tugouxp]

Hi castro:
  
   i do this because i want to confirm the whether the webprocess need to connect with the system waylandserver, because the UI process has a nested wayland server. 
and this experiment said yes. 
so it is confused me why the webprocess connect both the nested and system wayland server.  can not the render operation be finished just through the nested waylandserver? 
why connect the weson(system waylandserver on my platform).


thanks for your support.
