GraphicsMagick 1.3.1 Released

I am proud to announce the release of GraphicsMagick 1.3.1.  This 
release is API/ABI compatible with GraphicsMagick 1.3, which is itself 
almost completely compatible with GraphicsMagick 1.2 and earlier.  It 
seems that GraphicsMagick 1.3.1 is safe to use since no serious bug 
reports have been reported to date.

GM 1.3.1 offers even more performance than the initial 1.3 release 
does.  A new configure option '--disable-openmp-slow' is provided to 
allow for disabling OpenMP enhancements for algorithms which may 
actually run slower on operating systems with crummy thread libraries 
(i.e. FreeBSD and OS-X).  A benchmark performance report comparing 
latest ImageMagick with GraphicsMagick 1.3.1 may be seen at
"http://www.graphicsmagick.org/benchmarks.html".  It is clear that the 
internals of GM are quite a lot faster than IM, and that GM runs much 
more efficiently on older hardware.

Visit the GraphicsMagick web site at "http://www.graphicsmagick.org/", 
or download the release from 
"https://sourceforge.net/project/showfiles.php?group_id=73485".

The following are the changes in this release from GraphicsMagick 1.3:

Security Fixes:

   * None.

Bug fixes:

   * RPM build, Fixes to successfully build binary RPMs for Red Hat
     Linux 4.

   * MSL/conjure, Fix bug with attributes becoming appended to
     themselves.  Fix memory leaks.

Feature improvements:

   * New --disable-openmp-slow configure option for disabling use of
     OpenMP for algorithms which may run slower on operating systems
     with crummy thread libraries.

   * JPEG, Allow user to specify DCT encoding method via
     jpeg:dct-method define.  Also allow control over whether huffman
     encoding is used via jpeg:optimize-coding define.

Performance Improvements:

   * OpenMP (parallel processing) improvements for these functions:

     - Rotate by 90 and 270 degrees (-rotate)
