WebKitFaviconDatabase provides access to the icons associated with web sites.
WebKit will automatically look for available icons in <link> elements on opened pages as well as an existing favicon.ico and load the images found into a memory cache if possible. That cache is frozen to an on-disk database for persistence.
If “enable-private-browsing” is TRUE, new icons
won't be added to the on-disk database and no existing icons will
be deleted from it. Nevertheless, WebKit will still store them in
the in-memory cache during the current execution.

void webkit_favicon_database_get_favicon (WebKitFaviconDatabase *database,const gchar *page_uri,GCancellable *cancellable,GAsyncReadyCallback callback,gpointer user_data);
Asynchronously obtains a cairo_surface_t of the favicon for the given page URI. It returns the cached icon if it's in the database asynchronously waiting for the icon to be read from the database.
This is an asynchronous method. When the operation is finished, callback will
be invoked. You can then call webkit_favicon_database_get_favicon_finish()
to get the result of the operation.

a newly allocated URI for the favicon, or NULL if the
database doesn't have a favicon for page_uri

“favicon-changed” signalvoid user_function (WebKitFaviconDatabase *database, gchar *page_uri, gchar *favicon_uri, gpointer user_data)
This signal is emitted when the favicon URI of page_uri
has
been changed to favicon_uri
in the database. You can connect
to this signal and call webkit_favicon_database_get_favicon()
to get the favicon. If you are interested in the favicon of a
WebKitWebView it's easier to use the “favicon”
property. See webkit_web_view_get_favicon() for more details.
