The comment about this routing_id in browser_plugin_guest.h has gone stale,
please update.

[Charlie Reis, 2014/12/17 00:06:44]

What is it set to instead?

(Is this still for routed messages, or is it for control messages now?)

[Fady Samuel, 2014/12/17 19:30:35]

These messages are control messages now. All BrowserPluginMsgs have instance_id
as their first parameter which is used for routing to the appropriate
BrowserPlugin.

[Fady Samuel, 2014/12/17 19:30:35]

Done.

   owner_web_contents_->Send(msg);
