2011-01-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* wand/magick_wand.c (MagickDescribeImage): Was sending
	descriptive output to stdout rather than returning it in an
	allocated string as intended.

2011-01-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/draw.c, wand/drawing_wand.c (MvgPrintf): Update to handle
	C99 vsnprintf() return values.

	* magick/draw.c, wand/drawing_wand.c (DrawAnnotation): Linux
	glibc does not pass extended text characters if "%.1024s"
	formatting convention is used.  Apparently it assumes that such
	characters may be UTF8 and returns -1 rather than outputting the
	string, even if it is assured to fit.

2010-12-30 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/mat.c Matlab file level clarification.

2010-12-27 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/mac.c New MacPaint image format reader added.

2010-12-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (WriteTIFFImage): Default to using a LZMAPRESET
	value of 1 based on testing which observed minimal benefit, and
	substantially more cost, from larger values.  Value may be
	specified by the user using command line syntax like `-define
	tiff:lzmapreset=7` for purposes of further experimentation.  Also
	adjusted default strip memory values for each preset level.

2010-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* PerlMagick/Magick.xs: Add LZMA support to PerlMagick.

	* coders/tiff.c (WriteTIFFImage): Add TIFF LZMA compressor support.

2010-12-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImages): Should send -verbose output to
	stderr rather than stdout since otherwise usage in pipelines may
	be broken.  Resolves SourceForge issue 3131790 "AVS -verbose
	prints to stdout".

2010-11-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* libtool: Upgrade to libtool 2.4.

	* coders/pnm.c (ReadPNMImage): Start work on reading NetPBM PAM
	format.  Parses PAM header but pixels are not returned yet.

	* magick/magic.c (StaticMagic): Be more specific when identifying
	PNM subformats.  Return the specific subformat name PBM, PGM, or
	PPM rather than PNM.  XV P7 format is now identified as "P7 332".
	Add detection of NetPBM PAM format.

2010-11-04  Glenn Randers-Pehrson  <glennrp@simple...>

	* magick/effect.c: Added 5x5, 6x6, and 7x7 circular ordered dither
	patterns to create a halftone effect.

2010-09-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Document pcl:fit-to-page define.

	* coders/pcl.c: Fix issue with printing a bi-level image on
	Konica-Minolta printers.  Define pcl:fit-to-page in order for the
	printer to scale the image to fit the page.  Patch by John
	Sergeant.

2010-09-19  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c: removed an apparently harmless extra invocation
	of ScaleShortToQuantum() due to cut-and-paste error in the
	update of 2010-06-02.  Also added a line to explicitly set
	the opacity of the background_color to OpaqueOpacity.

2010-09-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/pdf.c (ReadPDFImage): Enable use of PDF crop box via
	-define pdf:use-cropbox=true. Patch contributed by Chris Gilling.
	SourceForge patch ID 3063794, "Add support for using crop box for
	pdf import".

2010-09-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Magick++/lib/Image.cpp (backgroundColor, borderColor, matteColor):
	Opacity part of user-specified color needs to be preserved.
	Problem was reported by Alexander Zheltov.

2010-09-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am: Applied Automake 1.11.1 patch by Ralf Wildenhues
	which is necessary for the test suite to pass under Windows/MinGW
	due to command line length limits.

2010-09-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/draw.c, wand/drawing_wand.c: Pass full user-provided
	double precision resolution to renderer.  Truncating the
	resolution causes problems in some cases.  Resolves SourceForge
	bug 3058387 "Incorrect Copy Compositing through C interface".

2010-09-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (StringToList): Fix performance problem caused
	by using strlcpy.

	* coders/pnm.c (ReadPNMImage): Q8 build should be able to read
	16-bit PGM images.

2010-09-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MontageImageCommand): Fix memory leak of
	MontageInfo structure allocation in error handling path.

	* magick/montage.c (MontageImages): Fix crash observed with
	"-geometry x+0+0".  Problem reported by Simon Rainer.

2010-08-27  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* Makefile.am: Update to Automake 1.11.1.

2010-08-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Use AC_USE_SYSTEM_EXTENSIONS to enable system API
	extensions.

2010-08-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/pixel_cache.c (ModifyCache): Fix deadlock in
	ClonePixelCache() which was caused by using the same semaphore
	pointer in the source and destination images.  Problem was
	reported by Stefan Schramowski.

2010-08-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/info.c (WriteINFOImage): Added an `INFO` coder which
	produces textual image description output similar to `identify`
	but may be used with convert like "gm convert myfile info:-".
	Feature suggested by Stefan Schramowski.

2010-08-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/Makefile.am (TESTS_PS_XFAIL_TESTS): Expect EPT tests to
	fail if Ghostscript is missing.

	* configure.ac: Updated to Autoconf 2.67.

	* magick/render.c (DrawImage): Use StringToGravityType() to parse
	gravity values.

2010-07-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Document histogram-threshold setting.

	* magick/enhance.c (NormalizeImage): Add support for
	histogram-threshold setting to specify the percentage of the
	histogram to discard when computing image normalization parameters
	(default is 0.1%).  For example `-set histogram-threshold 0.01
	-normalize`.

	* www/api/types.rst: Update Image structure member documentation.

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

	* configure.ac: Add a test for posix_spawnp().  Results may be
	used in later development.

2010-07-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/Makefile.am (TESTS_PS_XFAIL_TESTS): PDF tests are expected
	to fail if Ghostscript is not available.

	* magick/utility.c (MagickStrlCat, MagickStrlCpy): Add handling
	for the case where size is zero in order to be conformant with the
	strlcat() and strlcpy() formal descriptions.  GraphicsMagick does
	its best to never pass a size of zero so an assertion that size is
	not zero remains in order to help catch bugs in GraphicsMagick.
	Issue was reported by Albert Cahalan.

2010-07-10  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c: Always scale tRNS color to 16-bit short.  Otherwise,
	transparency was sometimes lost while reading PNG files whose depth
	is different from the Quantum depth.

2010-07-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/tiff.c (LOG_TIFF_BLOB_IO): Define LOG_TIFF_BLOB_IO=1 when
	building GraphicsMagick in order to enable verbose logging from
	the TIFFClientOpen() registered callbacks when `coder` logging is
	enabled.

2010-06-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile.c: Deal with formats which don't have an extension
	by prepending the magic specifier to the file name specification.

	* coders/mpr.c (RegisterMPRImage): MPR and MPRI are not useful
	file extensions.

	* magick/command.c (CommandAccessMonitor): If the environment
	variable MAGICK_ACCESS_MONITOR is set to TRUE then also log
	invocations of the access monitor callback when -monitor is
	specified.  This feature is intended to assist with understanding
	when the access monitor is invoked, and the arguments which are
	passed.

	* magick/blob.c (OpenBlob): Throw an exception on error rather
	than depending on the invoking code to do so.  Resolves
	SourceForge bug #3023437 "Magick::Image::ping() does not throw
	exception in all cases".

2010-06-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c (MogrifyImage): The -colors, -map, and
	-monochrome options now take effect immediately rather than at the
	end of all other processing.  This is is more intuitive and
	reasonable but may impact the output of scripts which place these
	options prior to additional image processing operations.

2010-06-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (BlobToImage): If a temporary file must be used
	and the user has specified magic, then preserve the magic
	specifier when reading the temporary file.

	* coders/mat.c (RegisterMATImage): More accurately describe MATLAB
	format support as "MATLAB Level 5".

	* magick/magic.c (StaticMagic): Automatically detect MATLAB Level
	5 format based on file header.

	* PerlMagick/PerlMagickCheck.sh.in: Run PerlMagick tests in
	verbose mode so that all test output appears in "test-suite.log"
	if there is a failure.

	* coders/Makefile.am (coders_mat_la_LIBADD): MAT coder is
	optionally dependent on zlib so zlib should be listed as a
	dependency.

	* magick/blob.c (BlobToFile): MAGICK_IO_FSYNC=TRUE in the
	environment should cause file data to be explicitly synchronized
	prior to close.

2010-06-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/installer/inc/files-documentation.isx: There are
	not currently any JPEG files in the www/images directory to
	distribute.

2010-06-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* ltdl/config/ltmain.sh: Update libtool to 2.2.10.

	* magick/profile.c: Support lcms 2.0.

	* configure.ac: Add support for configuring for lcms 2.0,
	controlled via a new --without-lcms2 option.  By default lcms v2
	is used if it is available, otherwise v1.1X is used if it is
	available.

2010-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* ltdl/config/ltmain.sh: Update libtool to 2.2.8.

2010-06-02  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c correctly scale bKGD chunk data in Q16 build

2010-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/Magick++/Image.rst: Fix documentation error which wrongly
	recommended multiplication by size of PixelPacket.  Correction by
	Roel Baardman.

2010-05-23 Fojtik Jaroslav  <JaFojtik@seznam.cz>

	* coders/txt.c (ReadTXTImage): Ability to read multiple images.

2010-05-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/constitute.c (DispatchImage): `K` channel was always
	output as black for "CMYK" specification unless image matte flag
	was True.  Bug report and proposed solution by Lance Brown.

2010-05-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/shear.c (ShearImage): When one of the shear angles was
	specified as zero, the shear request was ignored entirely.  An
	simple optimization was using || rather than && to test the
	angles.  Resolves SourceForge issue #2991685 "Shear command does
	not handle zero angles correctly".

2010-05-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (InitializeMagick, DestroyMagick):
	InitializeMagick and DestroyMagick should be fully thread safe.

2010-05-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/gif.c (ReadGIFImage): Set the opacity value of the opaque
	color to transparent.  Patch by Tim Baker.

	* magick/image.c (SetImageColor): New function which is similar to
	SetImage() but which accepts the pixel color as a parameter rather
	than using the image background color.  Patch by Tim Baker.

	* magick/transform.c (CoalesceImages): When applying background
	disposal, fill the image with the transparent color, if one
	exists.  Patch by Tim Baker.  Resolves SourceForge patch ID
	2989472.

2010-05-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/txt.c (ReadTXTImage): Matte channel was not being enabled
	for non-opaque images.
	(ReadTXTImage): Opacity values need to be inverted prior to
	ingestion.

2010-04-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/options.imdoc: Documentation for -flatten and -mosaic has
	been improved.

	* magick/transform.c (MosaicImages): The -mosaic command now
	respects the composition option specified by -compose as well as
	the image background color specified by -background.

2010-04-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* coders/*.c, magick/*.c: Eliminate many benign data race
	conditions.

2010-04-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* GraphicsMagick.spec.in: Avoid duplicate copies of documentation
	files.  Put documentation into a versioned directory as used by
	Red Hat and CentOS.  Include archive libraries in developer
	package.

	* PerlMagick/Makefile.PL.in: Include support for DESTDIR so that
	RPM builds find the installed GraphicsMagick library.

2010-04-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* configure.ac: Under Solaris, make sure that OpenWindows Type1
	fonts do exist before deciding to use them.  OpenSolaris does not
	provide these fonts.

2010-04-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* GraphicsMagick.spec.in: Fix RPM build.  PerlMagick was not being
	built due to Makefile changes.  Resolves SourceForge issue
	#2952696 "RPM build broken: (Perl) file not found by glob".

	* magick/quantize.c (ReduceImageColors): Progress message should
	include the image file name.

2010-03-24  Glenn Randers-Pehrson  <glennrp@simple...>

	* Revised coders/jpeg.c to preserve the Exif profile.

2010-03-24  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c (ReadOnePNGImage): Eliminated some of the deprecated
	direct access to ping_info->members.
	Eliminated support of very old libpng versions (1.0.11 and earlier).

2010-03-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/delegate.c (GetPostscriptDelegateInfo): Add support for
	invoking "gs-cmyk" and "gs-cmyka" entries in delegates.mgk when
	ColorSeparationType or ColorSeparationMatteType is requested.
	Requisite entries in delegates.mgk are left for the user to add.

2010-03-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/magick.c (InitializeMagick): Don't initialize locale
	settings in InitializeMagick().  Resolves SourceForge bug #2967282
	"setlocale called by GraphicsMagick".

2010-03-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/{command.c, display.c}: Make sure that `animate`,
	`display`, and `identify` report any error only once, and then
	proceed to the next file name rather than quitting.  Problem was
	reported by Patrick Welche.

2010-03-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Released GraphicsMagick 1.3.12.
	
2010-03-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* PerlMagick/Makefile.am: Update PerlMagick/Magick.pm in the
	source tree (as required) since it is distributed source and
	contains the current version number.

2010-03-03  Glenn Randers-Pehrson  <glennrp@simple...>

	* coders/png.c: restored missing "US" in PNG_USER_CHUNK_CACHE_MAX
        at line 102.  Added some (unsigned long) typecasts on print statements
        to stifle warnings.

2010-03-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* png: Updated libpng to 1.2.43.  Resolves CVE-2010-0205 as
	pertains to GraphicsMagick Windows build.

2010-03-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* tests/rwfile_DCX_*.sh: Add tests for reading and writing DCX.

	* coders/pcx.c (WritePCXImage): DCX is not the same as PCX so only
	write DCX when requested to (and vice-versa).

	* utilities/tests/convert-pipe-out.sh: New test to verify that
	`convert` can write to stdout.

	* utilities/tests/convert-pipe-in.sh: New test to verify that
	`convert` can read from stdin.

	* utilities/tests/convert-pipe-filter.sh: New test to verify that
	`convert` works properly as a filter.

	* magick/image.c (SetImageInfo): The `rectify` parameter was found
	to not be sufficient to meet requirements since it was
	overloaded. The utilities would malfunction (hang or throw an
	exception) if requested to write to stdout.  As a result, this
	parameter has been changed to a binary flag type parameter.
	Existing True/False values are mapped to equivalents using the new
	binary flag.  This is intended to resolve Debian bug 571719
	"graphicsmagick: "convert" command is broken", reported by
	Vladimir Stavrinov.

2010-02-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Released GraphicsMagick 1.3.11.

2010-02-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/composite.c (GetCompositionPixelIteratorCallback):
	OverCompositeOp and AtopCompositeOp may be replaced with
	CopyCompositeOp in the case where neither image has a matte
	channel.

	* magick/command.c (ConvertImageCommand, MogrifyImageCommand):
	Added -extent option to apply a background color canvas behind the
	image. Added -compose option to allow specifying the composition
	operator to use.

	* magick/transform.c (ExtentImage): New function apply a
	background color canvas behind the image.

2010-02-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/command.c: Added a -thumbnail command to all of the GM
	sub-commands which currently support -resize.  This is a resize
	method optimized for speed when reducing the size of the image
	(such as when creating thumbnails).

2010-02-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/utility.c (LocaleCompare, LocaleNCompare): Fix array
	index underflow which occurs if the char type is signed and the
	character value is in the extended range.  Problem reported by
	Arseny Solokha.  Resolves SourceForge patch #2953314.

2010-02-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Released GraphicsMagick 1.3.10.

	individual files to enable easier viewing.

2010-02-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/GraphicsMagick.imdoc: Improve usage synopsis for
	`convert`. SourceForge feature request 2845965 "confusing
	documentation".

	* magick/display.c (MagickXDisplayImage): Image number was
	incorrect in window title.

	* magick/render.c (DrawImage): Path points data allocation was
	much larger than it needed to be.  Patch by Vladimir Lukianov.
	Resolves SourceForge issue 2947851 "Memory allocation error on
	vector graphics (or mem bomb)".

	* magick/constitute.c (WriteImages): +adjoin was not working
	correctly for the case when only one image frame is present.  With
	+adjoin and writing one frame to "foo%d.jpg" it was outputting
	"foo%d.jpg" rather than "foo0.jpg".  Problem reported by Frans
	Coetzee.

2010-02-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Released GraphicsMagick 1.3.9.

2010-02-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* doc/imdoc2man: Bare single quotes at the beginning of a line
	need to be escaped in order to make roff happy.  Problem reported
	by Daniel Kobras.

	* magick/command.c (ImportImageCommand): Don't assign a pointer to
	static constant data into an array which uses heap allocated data.
	Avoids a "double free" error when using gm import -frame.  Patch
	by Daniel Kobras.

	* magick/color_lookup.c (QueryColorname): XPM does not support
	RGBA color syntax, but it does support RGB.  Patch by Daniel
	Kobras.

	* magick/blob.c (OpenBlob): Only form multi-part filename when
	required.

	* magick/display.c (MagickXDisplayImage): The display `-update`
	option was only working in conjunction with the `-delay` option
	with a delay setting of 2 or greater.  Problem reported by Sami
	Liedes.  Patch by Vincent MAUGE.  Resolves Debian bug ID 414779.

2010-02-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/blob.c (OpenBlob): Only apply scene substitution to
	the filename if adjoin is false.

	* magick/constitute.c (WriteImage): If adjoin is true, then
	restore original filename specification since opening the blob
	modifies it.  Resolves Debian bug ID 552998.

	* magick/image.c (SetImageInfo): Don't check filename for scene
	substitution if adjoin is intentionally false.  This allows saving
	to file names which look like they contain a scene substitution
	pattern.

	* magick/command.c (MogrifyImage): Convolution failure results in
	a crash rather than an error report.  Resolves Debian bug ID
	539251.

	* magick/deprecate.c: The string constants LoadImageText,
	SaveImageText, LoadImagesText, and SaveImagesText should have been
	deprecated, rather than being entirely removed.

2010-01-31  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* www/Makefile.am (install-data-html): Make sure that only the
	necessary documentation files are installed.

2010-01-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/installer/inc/body.isx: Strip out executable
	components which depend on proprietary MFC and ATL libraries.
	This means that "gmdisplay.exe" and "ImageMagickObject" are no
	longer distributed or installed via the Windows setup installer.
	When a new display application is developed based on open source
	libraries, then the display functionality and associations can be
	restored.

2010-01-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/transform.c (FlattenImages): Apply the image background
	color under the initial canvas image if it is non-opaque.

	* magick/composite.c (MagickCompositeImageUnderColor): New private
	function to apply a color underneath a non-opaque image.

2010-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/prefetch.h: New header to provide wrapper macros for
	compiler-specific explicit prefetch APIs.

	* magick/effect.c (BlurImageScanlines): Solid color images which
	only differed in the matte channel were not being blurred.

	* magick/color.h (NotPixelMatch,PixelMatch): New macros to
	fully-compare a pixel, including matte.

	* magick/resource.c (SetMagickResourceLimit): Invoke
	omp_set_num_threads() to set thread limit if ThreadsResource is
	requested.

	* magick/pixel_cache.c (AllocateThreadViewSet): The number of
	cache views to allocate needs to be obtained from
	omp_get_max_threads().  Otherwise there is a crash if the number
	of threads is reduced from the original value.

2010-01-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* version.sh: Released GraphicsMagick 1.3.8.
	
	* NEWS.txt: Update for the 1.3.8 release.

	performance with ImageMagick 6.5.8-10.

2010-01-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/shear.c (RotateImage, ShearImage): Ensure that errors
	propagate up to the API user.  Don't overwrite a detailed
	exception message with a generic one.  Don't return a bogus image
	if there is an error.

2010-01-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* VisualMagick/installer/inc/files-base.isx: Third party
	executables not included in the Visual Studio build are no longer
	bundled in the GraphicsMagick installer.  This means that
	hp2xx.exe, mpeg2dec.exe, and mpeg2enc.exe are no longer
	distributed.

	* www/Magick++/Image.rst: Emphasize that InitializeMagick() MUST
	be invoked, and make sure that all of the examples show use of it.

2010-01-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/delegate.c (InvokeDelegate): Use MagickSpawnVP() under
	Windows as well.
	(InvokePostscriptDelegate): Use MagickSpawnVP() under Windows as
	well.

	* magick/utility.c (MagickSpawnVP): Moved from unix_port.c.
	Updated implementation to use spawnvp() rather than fork()/exec()
	under Windows.

	* configure.ac: Add check for Windows spawnvp function.
	Add check for process.h.

	* magick/semaphore.c (DestroySemaphore): POSIX mutex statically
	initialized via PTHREAD_MUTEX_INITIALIZER should not be destroyed.

	* configure.ac: DisableSlowOpenMP is now the default.  Use
	--enable-openmp-slow to enable OpenMP for algorithms which
	sometimes run slower rather than faster.

2010-01-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/version.h.in: Added MagickLibInterfaceNewest and
	MagickLibInterfaceOldest preprocessor defines so that applications
	may easily test for library versions while compiling.

2010-01-03  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/render.c (DrawPolygonPrimitive): Use restrict keyword.

	* magick/pixel_iterator.c: Use restrict keyword.

	* utilities/Makefile.am: Modules are supported in the shared
	library built so list-module.sh test should be expected to pass.

	* configure.ac: Add WITH_SHARED_LIBS conditional.

2010-01-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

	* magick/version.h.in: Update copyright years.

	* magick/semaphore.c: The return code from all pthread mutex APIs
	are now checked (not just initialize and destroy), and any error
	results in an immediate fatal exit.
