[Pharo-project] About at: in diplayProgress bar and multiLineRequest: queryString centerAt: aPoint initialAnswer: defaultAnswer answerHeight: answerHeight

Hi guys we will deprecate the usage of a location in progress bar and multiLineRequest: queryString centerAt: aPoint initialAnswer: defaultAnswer answerHeight: answerHeight because: - it is not really good that tools have to make reference to Sensor (which we should avoid and we will chase reference to Sensor) or to World activeHand cursorPosition and let the UIManager decides where to place the widgets - apparently multiLineRequest: queryString centerAt: aPoint initialAnswer: defaultAnswer answerHeight: answerHeight does not use the argument of centerAt: Let me know what you think. Such change will help clarifying layers. Stef
