I think there is a little bit more work to the proxy settings API:

You need to extend the ProxyServer type to support the new scheme:
http://developer.chrome.com/extensions/proxy.html#type-ProxyServer

It would be great to cover this in a roundtrip test. Maybe you can take this
test:
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/test/data/e...

And modify it as follows:
var httpProxy = {
  scheme: "quic",
  host: "1.1.1.1"
};
var httpProxyExpected = {
  scheme: "quic",
  host: "1.1.1.1",
  port: 80
};

Thanks.

Ah, I see.  Done.  (I hope)
