alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi

* ghostscript-font-std part had been moved from ghostscript-fonts to
urw-fonts. add dependency on urw-fonts and adjust gs-font-dir.
Bump PKGREVISION (and ABI bump).
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

GraphicsMagick 1.2 is the result of four years of additional
development and testing over and above the 1.1 release branch. In
these four years there have been a huge number of security fixes,
considerable performance enhancements, and new features have been
added. GraphicsMagick 1.2 continues to be mostly API and command
compatible with previous GraphicsMagick releases, and with ImageMagick
5.5.2 from whence it originated.
The following is the summarized (yet extensive!) list of changes in
this release. See the ChangeLog file for the full list of changes.
Security fixes:
* Fixes for CERT security alert TA04-217A described at
"http://www.us-cert.gov/cas/techalerts/TA04-217A.html".

vulnerability (IDefense 09.19.07).
* Do not access X11 or invoke convenience or stealth delegate programs
based on the file extension. In particular, these file extensions are
rejected for consideration as a format specifier: 'autotrace',
'browse', 'dcraw', 'edit', 'gs-color', 'gs-color+alpha', 'gs-gray',
'gs-mono', 'launch', 'mpeg-encode', 'print', 'scan', 'show', 'win',
'xc', and 'x'.
Bug fixes:

returns a success error code to GraphicsMagick. Verify that
Ghostscript has updated the output file before attempting to use it.
* Fixed a configure script syntax error when testing for trio.
* When requesting a list of formats, all of the modules in the module
search path are considered. Previously only the modules in the same
directory as the LOGO module were listed.
* Ensure that an image clip mask is respected by the negate algorithm.
* The BMP writer was sometimes writing incorrect BMP v4 files.
* Support reading and writing large PCX files.
* The Red Hat source RPM was failing to install the -config scripts
with execute permissions.
* Fixed a bug which could cause possible truncation while cloning the
image cache.
* Ensure that MIFF files indicate the compression which was actually used.
* Properly handle errors from libtiff so that corrupted images are not
output.
* Fix for stripped-TIFF reader. Discard extra samples beyond alpha in
scanline TIFFs.
* Endian option now controls TIFF byte-order rather than bit-order.
* TIFF writer can now write to pipes and other non-seekable output
destinations.
* JBIG writer was writing empty files for some libjbig releases.

New Utilities:
* A 'benchmark' subcommand is now available to benchmark the
performance of any other arbitrary subcommand (e.g. 'convert').
Feature improvements:
* LZW compression is now enabled by default.
* Support industry-standard subsampling notation like "4:2:2".
* If gm is executed under a traditional alternate name (e.g.
convert), it will invoke the appropriate sub-command. This allows
use of hard links, symbolic links, or just copying 'gm' to the
desired sub-command name in order to achieve 100% ImageMagick 5.5.2
utility compatibility.
* Provide the --enable-magick-compat option when configuring to install
ImageMagick utilities compatibility links.
* Identify -verbose output includes normalized (0.0-1.0) statistics.
* Identify and convert now print "pixels per second" rates to help
evaluate performance.
* Added the identify +ping option to force reading the complete file.
* The display program now supports the +progress option to disable any
visual progress indication (and hourglass cursor) while loading images.
* Support writing grayscale TGA files.
* Provide explicit support for Rec 601 and Rec 709 grayscale spaces.
* Include some support for a log RGB space based on the 2.048 density
range as defined for the Cineon Digital Film System.
* Added utilities command-line support for industry standard subsampling
notation like 4:4:4 and 4:2:2.
* Use MAGICK_IOBUF_SIZE to tune the size of the I/O buffer.
* Use -type Bilevel, Grayscale, TrueColor, or TrueColorMatte to
influence the type of image that Ghostscript returns.
* Use '-define tiff:fill-order={msb2lsb|lsb2msb}' to control TIFF bit
fill order.
* The -version option now dumps a feature list as well as the build
options.
* The -endian option now supports the option 'native'.
* A -monitor is added to enable progress monitoring for the command line
utilities.
* Use the -output-directory option to 'mogrify' to send output files to
the specified directory.
* Use the -create-directories option in conjunction with
-output-directory and 'mogrify' to create any necessary subdirectories.
* A Pixels resource limit is added. Use '-limit Pixels value' to limit
the maximum number of pixels in an image to 'value'.
* The already supported option '-type Optimize' is now honored by
formats that need to choose a subformat based on the properties of
the image. Grueling tests of many/all pixels are not performed
unless '-type Optimize' is supplied.
* Added a a -set option to the composite, convert, display, mogrify,
import commands in order to allow setting an image attribute.
* Display utility no longer defaults to reading from standard input if
stdin is not a tty.
* May now be configured to use the umem memory allocation library
available in Solaris 9, Update 3 and later, or from the portable umem
project.
Coder additions/improvements:
* Replaced existing DPX "support" with all-new DPX support conforming
to the SMPTE 268M-2003 standard.
* Cineon reader completely rewritten.
* TIFF coder is completely re-written. Now supports reading and
writing RGB, CMYK, and grayscale, scanline-oriented TIFF images
with arbitrary (1 to 32 bits) depth. Includes support for tiled
TIFF, floating point TIFF, LogLuv TIFF, BigTIFF, arbitrary depths,
and associated alpha.
* TIFF coder now supports retrieving and saving XMP profiles.
* MATLAB support is much improved and supports writing as well.
* WPG reader now supports CTM translations.
* ART format now supports writing.
* Support 32-bit raw RGB images.
* Support 32-bit raw CMYK images.
* Support 32-bit raw gray images.
* JP2 coder reads images in YCbCr colorspace and retrieves an embedded
ICC ICM color profile if present.
API enhancements:
* Added ExportImageChannel() and ImportImageChannel() APIs to support
exporting and importing pixel regions with an arbitary range of (1
to 32) bits per quantum.
* Added image leveling methods for Magick++.
* Generalized GetImageAttribute() support for retrieving wildcarded
attributes so that an identify -format specification like
``"%[dpx:*]"`` works as expected.
* Incorporated changes changes necessary so that GraphicsMagick can
work with the Ch C/C++ interpreter from SoftIntegration at
http://www.softintegration.com/.
* Added MagickAllocFunctions() to allow the API user to replace the
underlying memory allocator functions.
* Added MagickMalloc() and deprecated AcquireMemory().
* Added MagickCloneMemory() and deprecated CloneMemory().
* Added MagickMallocArray() to safely allocate N items of size S.
* Added MagickRealloc() and deprecated ReacquireMemory().
* Added MagickFree() and deprecated LiberateMemory().
Performance improvments:
* The DispatchImage() and ConstituteImage() functions incorporate
special case code for BGR, BGRO, BGRP, RGB, RGBO, and I formats (8
bit only) in order to improve performance dramatically.
* When writing very large JPEG images, don't enable Huffman compression
since doing so requires libjpeg to buffer the entire image in memory.
* When using the 'identify' -verbose option, -verbose must be specified
twice in order to obtain the color count. This makes normal use of
-verbose much faster.
* Significantly improved read/write speed for bilevel and gray images.
* TIFF I/O is considerably faster.
* Postscript writer is 10-15X faster.
* PNM formats writer is 10-100X faster.
* Rotate by 90 or 270 degrees is 2-9X faster.
Significant changes associated with GraphicsMagick 1.1.12 (released April 28, 2008)
Security Fixes:
o Do not access X11 or invoke convenience or stealth delegate
programs based on the file extension. In particular, these file
extensions are rejected for consideration as a format specifier:
'autotrace', 'browse', 'dcraw', 'edit', 'gs-color',
'gs-color+alpha', 'gs-gray', 'gs-mono', 'launch', 'mpeg-encode',
'print', 'scan', 'show', 'win', 'xc', and 'x'.
Bugs Fixed:
o magick/effect.c: Should now compile for ARM CPU.
o TIFF: Don't request Kodak private tags since these cause some
versions of libtiff to misbehave.
o When performing string expansion of image attribute identifiers, skip
those which require access to image pixels if image pixels are not
present.
o CropImageToHBITMAP(), ImageToHBITMAP(): Fix leak of bitmap handle.
