Marshalls the call from the RPC thread onto the // target AutomationPeer's context. // // Class has two major parts to it: // * Implementation of the I...Provider, which uses Dispatcher.Invoke // to call a private method (lives in second half of the class) via a delegate, // if necessary, packages any params into an object param. Return type of Invoke // must be cast from object to appropriate type. // * private methods - one for each interface entry point - which get called back // on the right context.
