* Function jpeg_to_ximage
*
* This routine converts compressed jpeg data associated with a _DtGrStream
* into an XImage.
*
* No X color allocation is done. The image is quantized down to MAX_COLORS
* during decompression, and an array of XColor structures with the red,
* green, and blue fields initialized to the colors used in the image is
* returned to the caller. Each pixel value in the XImage data is an index
* into this array. The caller must use this information to allocate X
* color cells and substitute the appropriate pixel values into the XImage
* data array before using the XImage.
*
* The routine makes use of a custom source data manager to allow the JPEG
* data source to be a _DtGrStream, a custom data destination manager to
* allow the decompressed and post-processed data to be written to an XImage,
* and a custom error handler to allow standard _DtGr error codes to be
* returned to the caller in the event of a JPEG library error.
