   An update that contains security fixes can now be installed.

Description:



   GraphicsMagick was updated to 1.3.29:

   * Security Fixes:

     - GraphicsMagick is now participating in Google's oss-fuzz project
     - JNG: Require that the embedded JPEG image have the same dimensions as
       the JNG image as provided by JHDR. Avoids a heap write overflow.
     - MNG: Arbitrarily limit the number of loops which may be requested by
       the MNG LOOP chunk to 512 loops, and provide the '-define
       mng:maximum-loops=value' option in case the user wants to change the
       limit.  This fixes a denial of service caused by large LOOP
       specifications.

   * Bug fixes:

     - DICOM: Pre/post rescale functions are temporarily disabled (until the
       implementation is fixed).
     - JPEG: Fix regression in last release in which reading some JPEG files
       produces the error "Improper call to JPEG library in state 201".
     - ICON: Some DIB-based Windows ICON files were reported as corrupt to an
       unexpectedly missing opacity mask image.
     - In-memory Blob I/O: Don't implicitly increase the allocation size due
       to seek offsets.
     - MNG: Detect and handle failure to allocate global PLTE. Fix divide by
       zero.
     - DrawGetStrokeDashArray(): Check for failure to allocate memory.
     - BlobToImage(): Now produces useful exception reports to cover the
       cases where 'magick' was not set and the file format could not be
       deduced from its header.

   * API Updates:

     - Wand API: Added MagickIsPaletteImage(), MagickIsOpaqueImage(),
       MagickIsMonochromeImage(), MagickIsGrayImage(), MagickHasColormap()
       based on contributions by Troy Patteson.
     - New structure ImageExtra added and Image 'clip_mask' member is
       replaced by 'extra' which points to private ImageExtra allocation. The
       ImageGetClipMask() function now provides access to the clip mask image.
     - New structure DrawInfoExtra and DrawInfo 'clip_path' is replaced by
       'extra' which points to private DrawInfoExtra allocation.  The
       DrawInfoGetClipPath() function now provides access to the clip path.
     - New core library functions: GetImageCompositeMask(),
       CompositeMaskImage(), CompositePathImage(), SetImageCompositeMask(),
       ImageGetClipMask(), ImageGetCompositeMask(), DrawInfoGetClipPath(),
       DrawInfoGetCompositePath()
     - Deprecated core library functions: RegisterStaticModules(),
       UnregisterStaticModules().

   * Feature improvements:
     - Static modules (in static library or shared library without
       dynamically loadable modules) are now lazy-loaded using the same
       external interface as the lazy-loader for dynamic modules.  This
       results in more similarity between the builds and reduces the fixed
       initialization overhead by only initializing the modules which are
       used.
     - SVG: The quality of SVG support has been significantly improved due to
       the efforts of Greg Wolfe.
     - FreeType/TTF rendering: Rendering fixes for opacity.
