		http://bugzilla.remotesensing.org/show_bug.cgi?id=581</a>.

	<li> libtiff/{tif_open.c, tiffio.h}: New function added:
	TIFFIsBigEndian(). Function returns nonzero if given was file written
	in big-endian order.

	<li> libtiff/tif_print.c: added (untested) support for printing
	SSHORT, SLONG and SRATIONAL fields.

	<li> libtiff/tif_fax3.c: Avoid reading CCITT compression options
	if compression type mismatches. See
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=565">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=565</a>.

	<li> libtiff/tif_strip.c: Never return 0 from the TIFFNumberOfStrips().

	<li> libtiff/tif_dirread.c: Workaround for broken TIFF writers which
	store single SampleFormat value for multisampled images. See
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=562">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=562</a>.

	<li> libtiff/tif_write.c: Allow in-place updating of the compressed
	images (don't work properly with all codecs). For details see GDAL bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=534">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=534</a>.

	<li> libtiff/tif_jpeg.c: Workaround for wrong sampling factors used
	in the Intergarph JPEG compressed TIFF images as per bug:
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=532">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=532</a>.

	<li> libtiff/tif_open.c: Use dummy mmap/munmap functions in
	TIFFClientOpen() when the appropriate client functions was not
	supplied by user.

	<li> libtiff/tif_dirread.c: Fixed problem with handling TIFF_UNDEFINED
	tag type in TIFFFetchNormalTag() as per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=508"
		http://bugzilla.remotesensing.org/show_bug.cgi?id=508</a>.

	<li> libtiff/tif_codec.c: Fixed typo in TIFFInitPackBits name as per:
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=494">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=494</a>.

	with the CCITT encoding modes as per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=483">
		http://bugzilla.remotesensing.org/show_bug.cgi?id=483</a>.
        We need more work on fax codec to support update mode.

	<li> libtiff/tiff.h: Fixed tag definitions for TIFFTAG_YCLIPPATHUNITS
	and TIFFTAG_INDEXED as per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=475">

	http://bugzilla.remotesensing.org/show_bug.cgi?id=468</a>.

	<li> libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags
	that are field_passcount=TRUE properly.  Arguably anonymous custom
	tags should be declared as passcount=FALSE, but I don't want to change
	that without a careful review.

	<li> libtiff/tif_write.c: Fixed reporting size of the buffer in case
	of stripped image in TIFFWriteBufferSetup(). As per bug
	<a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=460">
