 // A BrowserPluginGuest is the browser side of a browser <--> embedder
 // renderer channel. A BrowserPlugin (a WebPlugin) is on the embedder
 // renderer side of browser <--> embedder renderer communication.
 //
 // BrowserPluginGuest lives on the UI thread of the browser process. Any
 // messages about the guest render process that the embedder might be interested
 // in receiving should be listened for here.
 //
 // BrowserPluginGuest is a WebContentsObserver for the guest WebContents.
 // BrowserPluginGuest operates under the assumption that the guest will be
 // accessible through only one RenderViewHost for the lifetime of
 // the guest WebContents. Thus, cross-process navigation is not supported.

Why is this required here?

[Fady Samuel, 2014/09/08 20:46:23]

To convert "embedder_web_contents_" to a WebContents from a WebContentsImpl.

we are not allowed to access a WebContentsImpl from RWHVGuest.

[lazyboy, 2014/09/08 20:53:19]

I'd move embedder_web_contents() to browser_plugin_guest.cc then.
It's not so obvious there's a cast involved and embedder_web_contents() is not a
simple getter.

[Fady Samuel, 2014/09/09 14:58:17]

Technically I should also be renaming this to GetEmbedderWebContents to indicate
this is a non-trivial accessor. However, that requires my updating multiple
callsites with many OWNERS. Could I do that in a separate cleanup CL?

[lazyboy, 2014/09/09 15:24:04]

Sure, I'd put a todo here then.
