++ * BEWARE OF KLUDGE:  This subroutine is a hack for decoding illegal JPEG-in-
++ *                    TIFF encapsulations produced by Microsoft's Wang Imaging
++ * for Windows application with the public-domain TIFF Library.  Based upon an
++ * examination of selected output files, this program apparently divides a JPEG
++ * bit-stream into consecutive horizontal TIFF "strips", such that the JPEG
++ * encoder's/decoder's DC coefficients for each image component are reset before
++ * each "strip".  Moreover, a "strip" is not necessarily encoded in a multiple
++ * of 8 bits, so one must sometimes discard 1-7 bits at the end of each "strip"
++ * for alignment to the next input-Byte storage boundary.  IJG JPEG Library
++ * decoder state is not normally exposed to client applications, so this sub-
++ * routine provides the TIFF Library with a "hook" to make these corrections.
++ * It should be called after "jpeg_start_decompress()" and before
++ * "jpeg_finish_decompress()", just before decoding each "strip" using
++ * "jpeg_read_raw_data()" or "jpeg_read_scanlines()".
++ *
++ * This kludge is not sanctioned or supported by the Independent JPEG Group, and
++ * future changes to the IJG JPEG Library might invalidate it.  Do not send bug
++ * reports about this code to IJG developers.  Instead, contact the author for
++ * advice: Scott B. Marovich <marovich@hpl.hp.com>, Hewlett-Packard Labs, 6/01.
