   1. Check whether we need to stop making requests to the server.
   1. In response to the ProgressiveRasterIO call the format driver makes an asynchronous request to the server for data matching the requested resolution and window.
-  1. The driver parses the response from the server and sets the buffer on GDALAsynchRasterIOMessage.
-  1. GDALAsynchRasterIOMessage object is added to the format driver internal data queue.  If the queue size limit is exceeded the last message drops off.  Note the data for this message is still retained in the wavelet cache for the driver - just the rendering is discarded.
