// A BrowserPluginEmbedder handles messages coming from a BrowserPlugin's
// embedder that are not directed at any particular existing guest process.
// In the beginning, when a BrowserPlugin instance in the embedder renderer
// process requests an initial navigation, the WebContents for that renderer
// renderer creates a BrowserPluginEmbedder for itself. The
// BrowserPluginEmbedder, in turn, forwards the requests to a
// BrowserPluginGuestManager, which creates and manages the lifetime of the new
// guest.
