/**
 * nsIProgressEventSink
 *
 * This interface is used to asynchronously convey channel status and progress
 * information that is generally not critical to the processing of the channel.
 * The information is intended to be displayed to the user in some meaningful
 * way.
 *
 * An implementation of this interface can be passed to a channel via the
 * channel's notificationCallbacks attribute.  See nsIChannel for more info.
 *
 * The channel will begin passing notifications to the progress event sink
 * after its asyncOpen method has been called.  Notifications will cease once
 * the channel calls its listener's onStopRequest method or once the channel
 * is canceled (via nsIRequest::cancel).
 *
 * NOTE: This interface is actually not specific to channels and may be used
 * with other implementations of nsIRequest.
