Update GraphicsMagick to 1.3.14.

1.3.14 (February 25, 2012)
==========================

Security Fixes:

  * Windows bundled libpng updated to the 1.5.9 release, which fixes
    the dire CVE-2011-3026 buffer overrun bug.

Bug fixes:

  * EMF format : Fixed wrong module mapping which caused EMF reading
    to not work under Windows.

  * TGA format: Assume that 32-bit TGA files have an alpha channel,
    even if they are not marked as such.

  * XCF format: Fix reading XCF which is comprised of different sized
    layers.

  * JPEG & CineonLog: Convert RGB-compatible colorspaces
    (e.g. CineonLog) to RGB by default since that was the case prior
    to release 1.3.13.

  * RAW formats: Small memory leak in dcraw module was fixed.

  * Resize: ResizeImage() was ignoring its resize filter argument and
    was using the filter setting from the Image structure instead.

  * The mirror virtual pixel method was broken.

New Features:

  * Open64 Compiler Suite: Version 5.0 is fully supported.

  * Wand API: Added MagickExtentImage().

  * MEF RAW: Mamiya Photo RAW "MEF" format is now supported.

Feature improvements:

  * DPX format: Original file endianness is preserved by default.

  * PNG library: Updated libpng to 1.5.9 release.

  * TIFF library: Updated libtiff to 4.0.1 release.

  * Zlib library: Updated to zlib 1.2.6 release.

Performance Improvements:

  * Despeckle algorithm (-despeckle) is many times faster.
