That's interesting -- perhaps I should do some profiling on 32-bit ARM to
see where the inefficiency comes from.

Please tell your family that Galene's author said hi !

1. Add the button in galene.html and style it in galene.css.

2. In galene.js, add a callback that sends a broadcast user message:

    mybutton.onclick = e => {
        serverConnection.userMessage('ring', nil);
    };

3. In onUserMessage, add a handler for the new message:

    case 'ring': {
        let audio = new Audio('ring.mp3');
        audio.play();
        break;
    }

You have two solutions.  The quick and dirty one would be to edit the div
with class "login-container" in galene.html.  If you need to supply
passwords or change the username, you may do that in the function
'gotConnected' in galene.js.

The alternative would be to write your own login server that computes
a JWT token and redirects to Galene.  The advantage is that you can write
the server in any language you wish, but it's a little more complicated.
See the section 'Authentication Portal' of the file README.PROTOCOL.
