This interface is an extension of the ICoreWebView2Controller interface to
support visual hosting. An object implementing the
ICoreWebView2CompositionController interface will also implement
ICoreWebView2Controller. Callers are expected to use
ICoreWebView2Controller for resizing, visibility, focus, and so on, and
then use ICoreWebView2CompositionController to connect to a composition
tree and provide input meant for the WebView.
