Adds new CefDisplayHandler::OnContentsBoundsChange and CefDisplayHandler::GetRootWindowScreenRect callbacks. cefclient: Implement the above callbacks and call CefBrowserHost::NotifyScreenInfoChanged when the root window bounds change. cefclient: osr: Use real screen bounds by default. Pass `--fake-screen-bounds` for the old default behavior. Load https://tests/window in cefclient for additional implementation details and usage examples.
