<UL>
	<li> tiffio.h: Added VC_EXTRALEAN definition before including
	windows.h, to reduce the compile time.

	<li> tif_jpeg.c: Improve compilation under MinGW.

	<li> {tif_aux.c, tif_dir.c, tif_dir.h, tif_dirwrite.c,
	tif_print.c, tif_getimage.c}: Make InkSet, NumberOfInks, DotRange and

	<li> {tif_dir.c, tif_dir.h, tif_print.c}: Make RichTIFFIPTC,
	Photoshop and ICCProfile tags custom.

	<li> libtiff/*, contrib/*: Added 'dual-mode' error handling, enabling
	newer code to get context indicator in error handler and still
	remain compatible with older code: Done TIFFError calls everywhere
	except in tools.

	<li> tiffinfo.c: Print EXIF directory contents if exist.

	<li> {tif_dirinfo.c, tif_dirread.c, tif_dir.h, tif_dir.c}:

	<li> tif_dirread.c: One more workaround for broken StripByteCounts
	tag. Handle the case when StripByteCounts array filled with
	completely wrong values.

	<li> tif_dirinfo.c: Release file descriptor in case of failure
	in the TIFFOpenW() function as per bug

	with incorrect use of tif_row, to 'at line ... of
	strip/tile ...' style.
