This module provides a Perl interface to the amazing Graphviz, an open source
graph visualization tool from AT&T.
It is called GraphViz2 so that pre-existing code using (the Perl module)
GraphViz continues to work. GraphViz2 V 1 is not backwards compatible with
GraphViz V 2, despite the considerable similarity.

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.
Behavior Changes:
* DPX format: Original file endianness is preserved by default.
-update to 4.0.1 -- this only adds symbol versioning support to ease
transition from 3.x to 4.x; this is not used in pkgsrc so the
update is purely cosmetical
