 * To use a TlsInteraction with a TLS connection use
 * Gio::TlsConnection::set_interaction().
 *
 * Callers should instantiate a derived class that implements the various
 * interaction methods to show the required dialogs.
 *
 * Callers should use the 'invoke' functions like invoke_ask_password() to run
 * interaction methods. These functions make sure that the interaction is
 * invoked in the main loop and not in the current thread, if the current
 * thread is not running the main loop.
 *
 * Derived classes can choose to implement whichever interactions methods
 * they'd like to support by overriding those virtual methods. Any interactions
 * not implemented will return Gio::TLS_INTERACTION_UNHANDLED. If a derived
 * class implements an async method, it must also implement the corresponding
 * finish method.
