	* tools/tiff2ps.c: improvements and enhancements from Richard Nolde
	with additional command line options for Document Title,
	Document Creator, and Page Orientation

2010-07-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiffcrop.c: Patch from Richard Nolde to avoid a
	potentially unterminated buffer due to using an exceptionally long
	file name.

2010-07-08  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiff2pdf.c: Fixed ID buffer filling in
	t2p_write_pdf_trailer(), thanks to Dmitry V. Levin.

2010-07-07  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/tif_dirread.c: Really reset the tag count in CheckDirCount()
	to expected value as the warning message suggests. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=1963

2010-07-06  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER,
	TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE
	which should be set by value.

	* libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()
	and _TIFFFieldWithName() if the tag is not found in the tag table.
	This should be normal situation and returned NULL value should be
	properly handled by the caller.

2010-07-02  Andrey Kiselev  <dron@ak4719.spb.edu>

	* libtiff/tif_getimage.c: Avoid wrong math du to the signed/unsigned
	integer type conversions. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2207

	* tools/{tiff2bw.c, thumbnail.c, pal2rgb.c}: Fix the count for
	WhitePoint tag as per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2042

	* libtiff/tif_getimage.c: Check the number of samples per pixel when
	working with YCbCr image in PickContigCase(). As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2216

	* libtiff/tif_dir.c: Set the bogus post-decoding hook when processing
	TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when
	we don't need any post-processing. That helps to reset the hook if we
	previously set this field to some other value and the hook was
	initialized accordingly. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2035

2010-07-01  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffgt.c: Properly check the raster buffer allocations for
	integer overflows. As per bug
	http://bugzilla.maptools.org/show_bug.cgi?id=2108

	* m4/acinclude.m4: Update GL/GLU/GLUt/Pthread macros from the
	upstream.

	* libtiff/{tif_aux.c, tif_strip.c, tif_tile.c, tiffiop.h}: Move
	multiply_32() and multiply_64() functions into tif_aux.c file and
	rename them into _TIFFMultiply32() and _TIFFMultiply64() respectively.

2010-06-30  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiff2pdf.c: Better generation of ID field in
	t2p_write_pdf_trailer(). Get rid of GCC aliasing warnings.

	* tools/tiff2pdf.c: Fixed computation of the tile buffer size when
	converting JPEG encoded tiles.

	* tools/tiff2pdf.c: Better handling of string fields, use static
	string buffers instead of dynamically allocated, use strncpy() instead
	of strcpy(), control the string lengths.

2010-06-25  Andrey Kiselev  <dron@ak4719.spb.edu>

	* tools/tiffcp.c: Initialize buffer arrays with zero to avoid
	referencing to uninitialized memory in some cases (e.g. when tile size
	set bigger than the image size).

2010-06-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tools/tiffcrop.c: Patch from Richard Nolde. Reject YCbCr
	subsampled data since tiffcrop currently doesn't support it.  Fix
	JPEG support.

2010-06-13  Frank Warmerdam  <warmerdam@pobox.com>

	* libtiff/tif_dirinfo.c: Fix invocation of tag compare function (#2201)

	* tools/tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return"
	in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
	wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
	size is larger.  Also, there are a bunch of places that try to
	memset() a malloc'd buffer before checking for malloc failure, which
	would result in core dump if there actually were a failure. (#2211)

2010-06-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to
	avoid compiler warnings if parameter types are not sign
	consistent.

	* libtiff 4.0.0alpha6 released.

	* tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected
	European page size dimensions.  Added an option to allow the user
	to specify a custom page size on the command line.  Fix the case
	where a page size specified with a fractional part was being
	coerced to an integer by retyping the variables that define the
	paper size.

	* html/index.html: Update for the 3.9.3 release.

	* tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject
	YCbCr subsampled data since tiffcp currently doesn't support it.
