/*-----------------------------------------------------------------------------
* This is the callback routine from the IJG JPEG library used to supply new
* data to the decompressor when its input buffer is exhausted. It juggles
* multiple buffers in an attempt to avoid unnecessary copying of input data.
*
* (A simpler scheme is possible: It's much easier to use only a single
* buffer; when fill_input_buffer() is called, move any unconsumed data
* (beyond the current pointer/count) down to the beginning of this buffer and
* then load new data into the remaining buffer space. This approach requires
* a little more data copying but is far easier to get right.)
*
* At any one time, the JPEG decompressor is either reading from the necko
* input buffer, which is volatile across top-level calls to the IJG library,
* or the "backtrack" buffer. The backtrack buffer contains the remaining
* unconsumed data from the necko buffer after parsing was suspended due
* to insufficient data in some previous call to the IJG library.
*
* When suspending, the decompressor will back up to a convenient restart
* point (typically the start of the current MCU). The variables
* next_input_byte & bytes_in_buffer indicate where the restart point will be
* if the current call returns FALSE. Data beyond this point must be
* rescanned after resumption, so it must be preserved in case the decompressor
* decides to backtrack.
*
* Returns:
* TRUE if additional data is available, FALSE if no data present and
* the JPEG library should therefore suspend processing of input stream

* For the non-NULL rows of interlaced images, you must call

* just return) and for non-interlaced images (it just does the
* memcpy for you) if it will make the code easier. Thus, you
* can just do this for all cases:
*
* png_progressive_combine_row(png_ptr, old_row, new_row);
*
* where old_row is what was displayed for previous rows. Note
* that the first pass (pass == 0 really) will completely cover
* the old row, so the rows do not have to be initialized. After
* the first pass (and only for interlaced images), you will have
* to pass the current row, and the function will combine the

* The nsIChannel interface allows the user to construct I/O requests for
* specific protocols, and manage them in a uniform way. Once a channel
* is created (via nsIIOService::NewChannel), parameters for that request
* may be set by using the channel attributes, or by QueryInterfacing to a
* subclass of nsIChannel for protocol-specific parameters. Then the actual
* request can be issued in one of several ways:
*
* - AsyncRead and AsyncWrite allow for asynchronous requests, calling
* back the user's stream listener or observer,
* - OpenInputStream and OpenOutputStream allow for synchronous reads
* and writes on the underlying channel.
*
* After a request has been completed, the channel is still valid for
* accessing protocol-specific results. For example, QueryInterfacing to
* nsIHTTPChannel allows response headers to be retrieved that result from
* http transactions.
*
* Note that a channel is really only valid for one request. Reusing a channel
* after a request has completed for a subsequent request may have undefined
* results, depending on the channel implementation.
*
* Also of note are a special kind of channel called "transports." Transports
* also implement the nsIChannel interface, but operate at a lower level from
* protocol channels. The socket and file transports are notable implementations
* of transports and allow higher level channels to be implemented. The cache
* may also behave as a transport, and possibly things like sound playing services
* etc. Transports usually operate in a separate thread and often multiplex
* multiple requests for the same kind of service or resources.
