optional: instead of accessing web_contents_ (private member from a static
method), you could call web_contents() API (provided by WebContentsDelegate*).

[halliwell, 2015/02/24 06:23:43]

I don't believe there is such an API?  WebContentsDelegate actually maintains an
entire set of WebContents*'s.

Is private member from a static method a problem in the style guide?  If so, we
could add an accessor into CastWindowAndroid.  If not ... I don't personally
have a problem with it, at least not for simple cases like this.
