public interface CefriumDisplayHandler
Display-related notifications (favicon, load progress, console messages, status text, media-device usage). Mirrors parts of CEF's CefDisplayHandler that are not already delivered via CefriumBrowser.Callback / the URL/title listeners. All methods are default no-ops, so implement only what you need. Register with CefriumBrowser.setDisplayHandler(CefriumDisplayHandler).

Delivered on the browser UI thread.
