Log message:
graphics/graphviz: Update to 7.1.0

## [7.1.0] – 2023-01-21

### Added

- The command line option `--help` has been added as an alias for `-?`. #1618
- The command line option `--version` has been added as an alias for `-V`. #1618

### Fixed

- The Autotools build system no longer errors when attempting libANN discovery
  during cross-compilation. This was a regression in Graphviz 7.0.6. #2335
- Graphs with more than 46341 (⌈√INT_MAX⌉) nodes no longer crash `twopi`. #1999
- Compatibility with `/bin/sh` has been restored in the Autotools build system.
  This was a regression in Graphviz 7.0.6. This restores the ability to compile
  on NetBSD which was fixed in 7.0.4 but regressed in 7.0.6. #2340
- `ccomps` no longer crashes when failing to open files.

Log message:
graphics/graphviz: Update comment in patch.

Nonportable shell syntax was fixed upstream.

Log message:
graphics/graphviz: Update to 7.0.6

Patch for configure.ac modified (nonportable syntax "==").

## [7.0.6] - 2023-01-06

### Changed

- The Autotools build system no longer looks for `python` binaries. The Python
  interpreter is unconditionally assumed to be `python3`. The configure option
  `--enable-python` is now an alias for `--enable-python3`.
- The Autotools and CMake build systems, when building `gvedit`, will now look
  for and use Qt6 in preference over Qt5. #2233
- Reserved stack size on Windows for the `dot.exe` binary has been increased
  from ~3.8MB to 32MB. #1710
- Reserved stack size on macOS for the `dot` binary when built with CMake has
  been increased from 8MB to 32MB. #1710
- The Autotools build system can now find libANN on Debian-based operating
  systems, enabling compilation of libmingle and `mingle`. #1835
- The `webdot` web server interface to Graphviz has been removed. For a modern
  replacement, see for example https://github.com/magjac/d3-graphviz. #1131

### Fixed

- The modgraph.php example no longer includes gv.php, which is no longer
  generated by SWIG 4.1.0. #2322

Log message:

Log message:
graphviz: updated to 7.0.5

7.0.5 – 2022-12-23

Fixed

Using style attributes in excess of 128 bytes and/or 63 individual styles no
longer results in out-of-bounds memory accesses.

Log message:
graphviz: updated to 7.0.4

7.0.4

Fixed

- The `alt` attributes are once again set in the cmap output. This was a
 regression in Graphviz 7.0.2, that intentionally removed these but did not
 account for the W3C specification making these attributes required when the
 `href` attribute is set.
- Building Graphviz from source using the Autotools build system in now possible
 on NetBSD.
- The ortho library now allocates trapezoid structures on-demand, removing the
 “Trapezoid-table overflow” error that previously occurred when its upfront
 estimation was exceeded.

7.0.3

Changed

* Support for the Intel C Compiler in the Autotools build system has been
 removed.
* Fallback typedefs for `ssize_t` have been removed from the CMake build system.

Log message:
graphics/graphviz: Update to 7.0.2

Remove patches for GUILE and PHP (options no longer supported by pkgsrc).

## [7.0.2] – 2022-11-18

### Added

- The `cluster`, `dot_builtins`, `dot2gxl`, `gv2gxl`, `gvedit`, and `prune`
  utilities are now included in the CMake build system. #1753, #1836

### Changed

- `gvedit` now uses a relative path from its own executable to discover its
  attributes file, `../share/graphviz/gvedit/attrs.txt`. This should make it
  more relocatable and make its behavior more consistent across operating
  systems.
- `alt` tags are no longer set in the cmap output. #265

### Fixed

- `gxl2gv`, when dealing with `name` attributes, may be less likely to crash. We
  say “may be less likely” because a bug remains that makes a crash still
  the most likely outcome. #2300
- Gradient URL references in SVG output once again align with their targets
  (linear or radial gradients) when `id` attributes are in use. This was
  arguably a regression in Graphviz 6.0.1. #2307
- The CMake build system’s interactions with a Zlib installed in a non-system
  location has been improved.
- Do not try to install `gv.php` if using SWIG-4.1.0. Graphviz 7.0.1 changes
  listed SWIG 4.1.0 as supported, but there was an oversight that is fixed in
  7.0.2. Complete #2277, #2303
- Several compilation errors when building Smyrna on macOS have been fixed. This
  was a regression in Graphviz 7.0.1.
- A crash when using neato layout with large inferred per-node edge counts was
  fixed. #42

## [7.0.1] – 2022-11-09

### Added

- SWIG 4.1.0 is now supported in the Autotools build system. #2277, #2303

### Changed

- When built with zlib support, Graphviz will unconditionally use
  `deflateBound`. The only user-visible effect should be slightly decreased
  memory usage when using a zlib-compressed output format.
- The test suite only detects Graphviz companion programs adjacent to the first
  `dot` found in `$PATH` #2201

### Fixed

- Failure of arrowhead and arrowtail to respect penwidth #372 \
  Fixed also for the `diamond` and `tee`
  [edge arrow shapes](https://graphviz.org/doc/info/arrows.html#primitive-shapes).
- The CMake build system no longer uses the final install location as the
  staging area for example graphs and templates during `cpack`. This bug was
  introduced in Graphviz 4.0.0. #2232
- The CMake build system uses corrected paths to DevIL and FreeType headers and
  libraries when discovered.
- The CMake build system under MinGW no longer attempts to install third party
  Expat and Getopt libraries.

## [7.0.0] – 2022-10-22

### Changed

- **Breaking**: An `outline_width` field has been added to the `Agnodeinfo_t`
  struct.
- **Breaking**: An `outline_height` field has been added to the `Agnodeinfo_t`
  struct.
- When using the CMake build system, the minimum requirement has been increased
  from CMake 3.9 to CMake 3.13.0.
- When compiling Graphviz with the Intel C Compiler, the Autotools build system
  no longer suppresses `-ffast-math`. Users relying on this are encouraged to
  investigate what in their build environment is appending a flag their C
  compiler does not support.
- The `-ffast-math` compiler flag is no longer enabled by the Autotools build
  system.
- Reserved stack size on Windows for the `dot.exe` binary has been increased
  from the default 1MB to ~3.8MB.

### Fixed

- Issues with GCC 8, `-O3` and `-ffast-math` #1412
- Problem building Graphviz-5.0.1: undefined symbols `__*_finite` #2296
- Failure of arrowhead and arrowtail to respect penwidth #372 \
  Fixed for all
  [polygon-based node shapes](https://graphviz.org/doc/info/shapes.html#polygon)
  (except for the `cylinder` node shape) and for the
  [edge arrow shapes](https://graphviz.org/doc/info/arrows.html)
  `normal`, `inv`, `box` and `dot`

### Removed

- Support for the MOSEK commercial solver has been removed. The `MOSEK`
  build-time macro no longer does anything.

Log message:
*: bump PKGREVISION for libunistring shlib major bump

Log message:
graphviz: updated to 6.0.2

6.0.2

Fixed

- Using `aspect` with a custom value in the `packmode` attribute is no longer
  misparsed.
- Smyrna bounding box computation has been corrected. There was a regression in
  4.0.0 that resulted in a degenerate bounding box being computed for any input
  graph.
- Smyrna warnings about the `on_attrRB0_clicked` and `on_attrSearchBtn_clicked`
  handlers being not found have been fixed and the buttons to which they are
  wired should be functional again. This was a regression in 2.50.0
- Smyrna warnings about the `mAttributesSlot` handler being not found have been
  fixed and the button to which it is wired should be functional again. This was
  a regression in 2.49.2
- Graphviz no longer fails to load private Ghostscript symbols ("Could not load
  `libgvplugin_gs.so.6`)
- trailing commas issue with fdp layout
- Missing `-S` in `sccmap` man page usage summary.
- In `sccmap`, a `-v` option following a `-S` option now re-enables strongly
  connected component output that the man page implied.
