Allow ResponseWithReturnValueInPayload to be passed into dtxConnection.Dispatch

[cziter15]

DESCRIPTION

When using a custom dispatcher for channel graphics messages, it appears that the ResponseWithReturnValueInPayload message type is returned periodically. However, the func (g GlobalDispatcher) Dispatch(msg Message) function currently only handles UnknownTypeOne. To properly receive GPU statistics, I had to modify the dispatcher to handle the ResponseWithReturnValueInPayload type as well, ensuring it is correctly passed into the Dispatch function.

Here's pseudocode for reference:

type mDispatcher struct {
}

func (md*mDispatcher ) Dispatch(msg dtx.Message) {
}

func (mp* mProvider)  InitializeWithDispatcher(device ios.DeviceEntry, msgDispatcher dtx.Dispatcher) error {
	conn, err := connectInstruments(device)
	conn.MessageDispatcher = msgDispatcher
	channel := mp.dtxConn.RequestChannelIdentifier(graphicsChannelName, nil)
	_, err := channel.MethodCall("startSamplingAtTimeInterval:", 0)
	conn.MessageDispatcher = msgDispatcher
	mp.dtxConn = conn
	return nil
}
