Log Message:
Update GraphicsMagick to 1.2.2.

1.2.2 (May 28, 2008)
===================

Bug fixes:

  * Documentation is now installed according to the conventions
    established by the configure script. This results in documentation
    being installed under /usr/local/share/doc/GraphicsMagick by default.

  * HWB colorspace now works correctly.

  * Composition with CopyOpacity now produces an image with transparency
    (as expected).

  * Composition now preserves the canvas colorspace.

  * Composition with a displacement map (-displace) no longer leaks an
    image.

  * Composition now handles CopyBlack properly for CMYK images.

  * Alpha composition now works as expected when both pixels involved
    include transparency.

  * -gamma multiple channel syntax now works as documented.

  * PerlMagick: Dissolve composition with Opacity now works correctly.

  * TIFF: Was accidentially converting CMYK images to RGB.

  * TIFF: Reject JPEG compression when writing CMYK images.

  * Should now compile with Visual C++ 2008.

  * Detects libbz2 and libxml2 and builds properly with them in a MinGW
    build.

Performance improvments:

  * Exploratory support for OpenMP in the image resize code.  Can result
    in significant performance improvement when significantly reducing
    the image size on multi-core systems, but little to no improvement
    when the input and output images are close to the same size. Add
    --enable-openmp to the configure options to enable using OpenMP.

Feature improvements:

  * Composition now supports CopyCyan, CopyMagenta, CopyYellow, and
    CopyBlack in order to copy CMYK channels into an image. CMYK copy
    composition operators automatically set the image colorspace to CMYK
    so that everything just works.
