svglib 2.1.0

Added

• Declared support for Python 3.14 (added the classifier and CI matrix
  entry across Ubuntu, macOS, and Windows, alongside the existing 3.9–3.13).
• Clipping paths now support <circle>, <ellipse>, and <polygon> clip
  shapes, in addition to paths and rectangles, and clipping masks referenced
  from within a <use> element.
• Transforms are now applied to clipping-path shapes, fixing clip paths that
  relied on previously unsupported transforms (issue #366).
• The gradient shape classes now implement getBounds(), so drawings that
  contain gradient fills can be measured — for example when used as a flowable
  by rst2pdf (issue #466).

Changed

• Renamed the gradient shape classes _LinearGradientShape and
  _RadialGradientShape to LinearGradientShape and RadialGradientShape.
  They appear in the rendered Drawing tree and were never meant to be
  private, so the leading underscore was misleading.

Removed

• Removed the deprecated _LinearGradientShape and _RadialGradientShape
  aliases. Use LinearGradientShape and RadialGradientShape instead.

Fixed

• The visibility property is now respected on shapes. Elements with
  visibility="hidden" (or collapse), set directly or inherited from an
  ancestor, were still rendered (issue #359).

• display: none set through a style attribute is now respected. Only the
  display presentation attribute was read, so <g style="display:none"> and
  <rect style="display:none"/> were still rendered (issue #401).

• Embedded <image> geometry is no longer truncated to whole points. The
  x, y, width, and height of an SVG <image> were each passed through
  int(), so a raster placed at fractional coordinates landed up to ~1pt away
  from a vector element with identical coordinates. Because width/height were
  truncated too, the error grew across the image rather than being a constant
  shift (issue #490).

• font-family values are now split per CSS instead of on whitespace. An
  unquoted multi-word name such as font-family: Cascadia Code was split into
  Cascadia and Code, so a font registered under its full name was never
  found (issue #374). Commas inside a quoted name (font-family: "Foo, Bar", Arial) no longer split the list either; that previously handed shlex an
  unbalanced quote and raised ValueError: No closing quotation, aborting the
  conversion of a valid value.

• Replaced locale.getdefaultlocale() (used for <switch> systemLanguage
  matching) with a small environment-variable lookup. getdefaultlocale() is
  deprecated and is removed in Python 3.15; the replacement keeps the same
  behaviour, emits no deprecation warning on 3.12–3.14, and adds unit tests for
  the language-matching path.

• Clipping paths now support the clip-rule attribute instead of incorrectly
  using fill-rule (issue #485).

• fill="url(...)" and gradient xlink:href values are now matched correctly
  when the referenced id is quoted (url('#name'), url("#name")) or
  contains a right parenthesis; the previous regex rejected or truncated
  these forms.

• Rendering to reportlab.graphics.renderSVG.SVGCanvas (as used by
  easy-thumbnails[svg]) no longer raises
  AttributeError: 'SVGCanvas' object has no attribute 'beginPath' when
  drawing a clipped gradient; that canvas doesn't implement beginPath(),
  so the gradient's clip path is now skipped on it instead of erroring.

Type safety and internal quality (no behavior change)

• Completed static type annotations for svglib.py; the package now passes
  mypy --strict on its own source, with a single documented per-module
  override for the untyped reportlab/cssselect2 base classes it subclasses.
• Pinned a [tool.mypy] configuration in pyproject.toml and now enforce mypy
  in CI (new type-check.yml workflow) and via a local pre-commit hook, so type
  regressions fail before merge.
• Tightened internal gradient handling types: parsed gradient definitions now
  use a TypedDict instead of an opaque Dict[str, Any], and the internal
  group/parent parameters are typed as Optional[Group].
• Added docstrings to the remaining undocumented functions in svglib.py,
  bringing documentation coverage to 100%.

Tooling and housekeeping

• Removed the DeepSource configuration. Its checks were redundant with ruff,
  mypy --strict, CodeQL, and the pytest matrix, and only produced recurring
  noise on pull requests.
• Removed the long-defunct uniconv sample tests. They contained no assertions
  and shelled out to UniConvertor, an abandoned Python 2 tool, so they had been
  permanently skipped.
• Fixed and revived the Windows CI workflow. It was a disabled placeholder that
  compiled GTK/Cairo from source (a ~20–40 minute step); it now runs a real
  CPython 3.9/3.13 matrix in well under a minute by dropping the source build
  and skipping the network-heavy sample tests on Windows (they already run on
  Ubuntu and macOS). The redundant manual Windows workflow was removed.
