* The rough outline this JPEG decompression operation is:
*
* allocate and initialize JPEG decompression object
* specify data source (eg, a file)
* jpeg_read_header(); // obtain image dimensions and other parameters
* set parameters for decompression
* jpeg_start_decompress();
* while (scan lines remain to be read)
* jpeg_read_scanlines(...);
* jpeg_finish_decompress();
* release JPEG decompression object
