X11 Forwarding example

[lucky62 <lucky62@xxxxxxxxxx>]

Hello, Is there any working example of X11 Forwarding?

Tutorial - Chapter 7: Forwarding connections (tunnel) 
<https://api.libssh.org/stable/libssh_tutor_forwarding.html> says:

*/How to establish X11 tunnels with libssh has already been described in 
this tutorial./*

*//*

*/See also/**/- x11/*

But I cannot find where it is described.

I would like to help with implementation of X11 forwarding into Remmina 
software.

This feature is heavily requested but not implemented.
