GraphicProducerWrapper(GPW) changed how the methods of BpGraphicBufferProducer(BpGBP) are executed. First, "fake" BpGBP is created. Its remote is GPW. The GPW has wrapped the real BpGBP. All the method calls to the fake BpGPB will be intercepted by the GPW inside it when the methods run into remote()->transact(). Then the GPW will invoke the transact() of the real BpGBP. And Everything runs well except that the GPW forgets to store the transact status and always return NO_ERROR to the fake BpGBP. It would be disastrous if the binder call of the IGBP failed and the out parameter "reply" of transact() was in unkown state. E.g. the queueBuffer() in the fake BpGBP will try to operate on the "reply". This will crash the SurfaceFlinger.
