graphics/graphviz: Update to 8.1.0

## [8.1.0] – 2023-07-06

### Added

- On non-Windows platforms, new `-Tvt100` and `-Tvt100-24bit` output formats
  are available that do rudimentary rendering to a terminal that supports ANSI
  escape sequences.
- Some notes about the interaction with wide-oriented streams were added to
  the cgraph man page.

### Changed

- When memory allocation failures cause Graphviz to exit, information about
  the failing allocation is included in the error message.

### Fixed

- Failure of arrowhead and arrowtail to respect penwidth #372 \
  Fixed also for the `curve` and `icurve`
  [edge arrow shapes](https://graphviz.org/doc/info/arrows.html#primitive-shapes).
- Iteration calculations based on `nslimit` and/or `nslimit1` attributes are
  clamped to `[0, INT_MAX]`. That is, calculations that result in a negative
  number of iterations are rounded up to `0` and those that result in a number
  of iterations that exceeds `INT_MAX` are rounded down to `INT_MAX`. Iteration
  numbers outside this range do not have useful behavior, but could be caused
  unintentionally by users.
- Setting `xdotversion` attributes that parse as greater than 17 (`xdotversion`
  is parsed as a series of digits, ignoring all non-digits) no longer causes an
  out of bounds read when rendering to xdot. #2390
- Icon size in the macOS Graphviz.app has been fixed so icons are no longer
  invisible.
- Compiling the portable source tarball on a machine with SWIG ≥ 4.1.0 no
  longer fails due to missing PHP files. #2388
- Syntax for a loop in `gvmap.sh` has been corrected. This was a regression in
  Graphviz 2.50.0. #2404

Log message:
graphics/graphviz: Declare minimum required API versions of librsvg and pango

As documented by upstream.

Log message:
graphics/graphviz: Update to 8.0.5

## [8.0.5] - 2023-04-30

### Changed

- Support for versions of Pango prior to 1.22.0 has been removed.
- On Windows, the Pango plugin now uses the newer `pango_layout_get_baseline`
  API.
- `dot` no longer installs a signal handler for `SIGINT`. This means typing
  Ctrl+C while `dot` is running will no longer attempt a partial render and exit
  with 0 status. Ctrl+C will have the standard behavior, typically aborting
  `dot`.

### Fixed

- A minor inaccuracy for some cases of clipping an edge to a polygon node
  boundary has been fixed.
- A minor inaccuracy in node width and height for some cases of rendering
  polygon nodes has been fixed.
- A minor inaccuracy for some cases of calculating text height from `fontsize`
  in the GD plugin has been fixed.
- A minor vertical misalignment of text in the GD plugin has been fixed.
- Instead of using the actual font height as given by the font metrics, an
  approximation based on font size was used in the Pango plugin.
- A minor inaccuracy for some cases of calculating text width and height in the
  Pango plugin has been fixed.
- A minor vertical misalignment of text in the Pango plugin has been fixed.
- Ensure `HAVE_PANGOCAIRO` is set when using CMake and the library is available.
- A minor inaccuracy in node width and height for some cases of defining
  polygon-based nodes has been fixed.
- A minor inaccuracy for some cases of calculating margin for record-based nodes
  has been fixed.
- A minor inaccuracy in node width and height for some cases of defining
  record-based nodes has been fixed.
- On all known supported platforms except 32-bit MinGW, graphs involving small
  distance constraints no longer cause a crash during majorization. #1554

## [8.0.3] - 2023-04-16

### Added

- A pre-processor script for resolving external image references
  (`image="http-"`) is now available. This enables graphs to reference \ 
images
  from intranet or internet locations. #1664

### Changed

- The accuracy of box overlapping checks during routing has been improved.

### Fixed

- makeCompoundEdge: Assertion `bez->sflag` failed. #1879
- Graphviz.app-s export functionality has been restored. This was a regression
  in Graphviz 5.0.0. #2375

## [8.0.2] - 2023-04-10

### Changed

- The Autotools build system can now detect a MacPorts-installed libANN. #1854
- Support for versions of Cairo prior to 1.10 has been removed.
- Graphs that generate rectangles with areas in the range [2--, 2-- - 1]
  are now supported. Previously areas greater than 2-- - 1 would be
  rejected. #2371

### Fixed

- Head and tail of `digraph` edges with `dir = both` were inverted if
  `splines = ortho` was used. The bug was only exposed on straight edges.
  Edges with at least one corner were unaffected. #144
- `_Gdtclft_Init` link errors when builting libtcldot_builtin using the
  Autotools build system have been resolved. #2365
- Incorrect string construction in the `pov` output formatter has been fixed.

## [8.0.1] - 2023-03-27

### Added

- When specifying a color in HSV format, it is now possible to give an
  additional fourth component for the alpha channel (opacity). #510

### Changed

- Graphviz will now exit when encountering a syntactically invalid HTML label
  instead of attempting to recover and continue. #1311
- **Breaking**: the `url_map_n` field in the `obj_state_t` struct is now a
  `size_t`.
- The limit of 5 unique `samehead` or `sametail` values per node has been
  removed. The maximum number of unique `samehead` or `sametail` values is now
  limited only by available memory. #452
- **Breaking**: The `size` field of the `elist` struct is now a `size_t`.
- **Breaking**: The `size` field of the `nlist` struct is now a `size_t`.
- **Breaking**: The `n_nodes` field of the `Agraphinfo_t` struct is now a
  `size_t`.
- **Breaking**: The `nspans` field of `textlabel_t.u.txt` is now a `size_t`.
- **Breaking**: The `sflag` and `eflag` fields of the `bezier` struct are now
  `uint32_t`s.
- **Breaking**: The `nvertices` field of the `stroke_t` struct is now a
  `size_t`.
- -no hard-coded metrics- warnings are now only printed once per font.
- The Autotools build system now discovers Python paths using `sysconfig`
  instead of `distutils.sysconfig`, making it compatible with Python 3.12. This
  alters the installation path of the Python Graphviz module to something more
  correct. #2332

### Fixed

- The `pic` output renderer uses PIC or troff comments where appropriate, fixing
  a problem that resulted in comments being misinterpreted by `groff` and being
  visible in the final output. #2341
- `gv2gxl` and `gxl2gv` correctly detect their mode (gv-gxl or gxl-gv) on
  Windows when called via an absolute or relative path. #2344
- Using C pre-processor line directives (`^\s*#(line )?\d+`) claiming a line
  number greater than `INT_MAX` no longer causes an integer overflow. #1318
- fdp cluster-cluster edges were correct but now drawn incorrectly. This was a
  regression in Graphviz 7.0.0. #2345
- Failure of arrowhead and arrowtail to respect penwidth #372 \
  Fixed also for the `cylinder`
  [node shape](https://graphviz.org/doc/info/shapes.html#polygon).
- Second periphery of a cylinder shaped node is not correct. #2297
- Graphs with more than 127 layers no longer cause out of bound writes. #2355
- htmltable.c assertions are no longer triggered by using HTML table cells too
  small to fit their content. #1622
- `dot2gxl -d` no longer crashes when receiving a closing `node` tag following a
  closing `graph` tag. #2094
- A buffer overflow in Smyrna when loading GVPR scripts has been corrected.
- A buffer overflow when loading a plugin with a long type string has been
  corrected.
- Graphs that involve more than 2000 stroke points during tapering calculations
  no longer cause out of bounds writes.
- Using `arrowsize=0.0` no longer triggers an assertion failure or crash during
  miter calculations. This was a regression in Graphviz 7.0.0. #2342
- When using the `beautify=true` attribute, beautification no longer confuses
  leaves and dimensions. This previously could have led to skipping calculations
  or infinite loops.
- When using the `beautify=true` attribute, the first and last nodes around a
  circular layout are no longer placed on top of each other. #2283
- Applying `concentrate=true` to duplicate edges no longer results in errors due
  to non-normal edges being found. #2087
- `splines=ortho` and `concentrate=true` when used in combination no longer
  causes crashes during spline construction. #2361
- Externally referenced SVG files with their opening `<svg` tag on the same line
  as their XML declaration are no longer ignored. #2352

### Removed

- The VML output renderer has been removed. This format has been superseded by
  SVG. #799
- Legacy man page references to `dotty` have been removed. `dotty` was removed
  in Graphviz 4.0.0.
- **Breaking**: The definition of the `elist_fastapp` macro has been removed.
- Versions of Librsvg prior to 2.36.0 are no longer supported.
- Versions of GDK prior to 2.0.0 are no longer supported.
- Versions of Glib prior to 2.36.0 are no longer supported.

  have been removed.
- **Breaking**: The `Agnodeinfo_t.outleaf` field and its `ND_outleaf` and
  `GD_outleaf` accessors have been removed.
- **Breaking**: The `Agraphinfo_t.has_sourcerank` field and its
  `GD_has_sourcerank` accessor has been removed.
- **Breaking**: The `Agraphinfo_t.has_sinkrank` field and its
  `GD_has_sinkrank` accessor has been removed.
- Support for the legacy Microsoft Visio VDX format has been removed.
- **Breaking**: The `arrow_at_start` and `arrow_at_end` parameters from the
  `gvrender_engine_t.beziercurve` callback have been removed.
- **Breaking**: The `GVRENDER_DOES_ARROWS` constant has been removed.
- The extra cmpnd.c code is no longer shipped in the Graphviz distribution
  tarball.
