/**
* \class CameraStream::PostProcessorWorker
* \brief Post-process a CameraStream in an internal thread
*
* If the association between CameraStream and camera3_stream_t dictated by
* CameraStream::Type is internal or mapped, the stream is generated by post
* processing of a libcamera stream. Such a request is queued to a
* PostProcessorWorker in CameraStream::process(). A queue of post-processing
* requests is maintained by the PostProcessorWorker and it will run the
* post-processing on an internal thread as soon as any request is available on
* its queue.
