{p5-}GraphicsMagick: updated to 1.3.32

1.3.32:

Special Issues:

It has been discovered that the 'ICU' library (a perhaps 30MB C++ library) which \ 
is now often a libxml2 dependendency causes huge process initialization \ 
overhead. This is noticed as unexpected slowness when GraphicsMagick utilities \ 
are used to process small to medium sized files. The time to initialize is often \ 
longer than the time to read the input file, process the image, and write the \ 
output file. If the 'ICU' dependency can not be avoided, then make sure to use \ 
the modules build. Please lobby the 'ICU' library developers to change their \ 
implementation to avoid long start-up times due to merely linking with the \ 
library.
Security Fixes:

GraphicsMagick is now participating in Google's oss-fuzz project due to the \ 
contributions and assistance of Alex Gaynor. Since February 4 2018, 343 issues \ 
have been opened by oss-fuzz and 331 of those issues have been resolved. The \ 
issues list is available at https://bugs.chromium.org/p/oss-fuzz/issues/list \ 
under search term "graphicsmagick". Issues are available for anyone to \ 
view and duplicate if they have been in "Verified" status for 30 days, \ 
or if they have been in "New" status for 90 days. There are too many \ 
fixes to list here. Please consult the GraphicsMagick ChangeLog file, Mercurial \ 
repository commit log, and the oss-fuzz issues list for details.
BMP reader: Fix heap overflow in 32-bit build due to arithmetic overflow. Only \ 
happens if limits are changed from defaults.
BMP reader/writer: Improve buffer-size calculations to guard against buffer \ 
overflows.
DIB reader: Reject files which claim more than 8-bits per pixel but also claim \ 
to be colormapped.
DIB reader/writer: Improve buffer-size calculations to guard against buffer \ 
overflows.
MIFF reader: Detect end of file while reading RLE packets.
MIFF reader: Fix heap overflow (for some files using RLE compression) caused by \ 
a typo in the code.
MAT writer: Added missing error handling to avoid heap overflow.
MNG reader: Fixed a small heap buffer overflow.
SVG reader: Fixed a stack buffer overflow.
TGA writer: Fix heap overflow when image rows/columns are larger than 65535.
TIFF reader: Rationalize tile width/height to reject large tile sizes which are \ 
much larger than the image dimensions.
TIFF reader: Apply memory resource limits to strip and tile allocations.
WMF reader: Fixed a division by zero problem.
XWD reader: Many heap buffer overflows and uses of uninitialized data were fixed.
Pixel cache: Now apply resource limits to pixel nexus allocations using the same \ 
limits (total pixels, width, height, memory) as applied to the whole image since \ 
some requests are directly influenced by the input file. More tests are added \ 
for arithmetic overflow. Care was taken to minimize performance impact due to \ 
the many extra checks.

Bug fixes:

See above note about oss-fuzz fixes.
Fixed include order of magick/api.h vs wand/wand_symbols.h.
WriteImage(): Eliminate use of just-freed memory in clone_info->magick when \ 
throwing exception due to no support for format.
Magick++/lib/Magick++/Drawable.h: Fix use of clang diagnostic syntax.
DIB: Preserve PseudoClass opaque representation if ICO mask is opaque.
JPEG reader: Restore ability to access detailed image properties while in 'ping' \ 
mode.
JPEG reader: Base test for "Unreasonable dimensions" on original JPEG \ 
dimensions and not the scaled dimensions.
JPEG reader: Allow input files to have a compression ratio as high as 2500. \ 
Extremely compressed files were being rejected.
FreeType renderer: Fixed a memory leak.
PDF writer: Fixed a memory leak.
PDF writer: Fixed a thread safety problem.
PICT reader: Fix a thread safety problem.
Exception reporting: Throwing an exception was not thread safe. Now it is.
Exception reporting: Handle the case where some passed character strings refer \ 
to existing exception character strings.
Command-line parser now does not attempt to read a list of filenames from a file \ 
in '@name' syntax if the path '@name' exists. Previously it would attempt to \ 
read a list of file names from 'name' even if '@name' did exist.
Rendering: Short-circuit path parsing and return and error immediately if an \ 
error occurs.

New Features:

Added support for writing the Braille image format (by Samuel Thibault).
WebP writer: Support WebP 'use_sharp_yuv' option ("if needed, use sharp \ 
(and slow) RGB->YUV conversion") via -define webp:use-sharp-yuv=true.
The version command output now reports the OpenMP specification number rather \ 
than just the integer version identifier.

API Updates:

ReallocateImageColormap() added to re-allocate an existing colormap.
Some improperly-exposed globals are now static as they should have been.
