dotCooCoo f14cc7f21e linesweeper: keep a copy of the crates.io 0.5.0 package in vendor/ 
Add the linesweeper 0.5.0 package to vendor/ with no file changed, so
that a fix to it can reach the Craft apps through this repository
without waiting for a linesweeper release. The GitHub repository its
manifest names is archived, and its README says development moved off
GitHub.

Leave out the test font (fonts live in craft-fonts), the logo artwork,
the snapshot images and the package's repository tooling. SOURCE.json
lists each with its hash.

Add a workspace exclude, a [patch.crates-io] entry, SOURCE.json with
the archive hash and per-file hashes, NOTICE and ATTRIBUTION.md rows,
and the package's tests in the backend test script. craft-prepress's
flatten feature now builds against the copy, so Cargo.lock drops the
package's registry source and checksum.

Changelog

0.5.0 - 2026-10-05

Changed

  • Boolean operations now attempt to preserve quadratic segments: they will no longer be automatically converted into cubics (issue 2774a82).

Fixed

  • Fixed a panic with polylines that have degenerate segments (issue da2b71b).
  • Fixed a panic with intersections exactly at the end of segments (issue f8732c7).
  • Fixed a panic (in slow-asserts mode only) from an ordering violation (issue df03063).
  • Fixed an infinite loop (issue a140a5f).

Added

  • Added some convenience methods to Contours (patch d4a09be).

0.4.0 - 2026-06-14

0.4.0 is the first release with a changelog entry; for previous releases, we didn't have enough users to worry about it.

Changed

  • There is a new "approximate" output mode, which is now the default. Previous versions of linesweeper provided strong correctness guarantees, but those guarantees made some cases slow and caused more subdivisions than necessary. Also, I think that those stronger guarantees are probably not needed for most applications -- other boolean ops libraries don't provide them as far as I know. So linesweeper now provides weaker guarantees by default. For the old behaviour, see Topology::contours_correct.
  • The winding direction conventions have changed; output curves have been reversed, so that they agree with kurbo's conventions.
  • The BinaryWindingNumber API has changed; it now uses the OneOfTwo enum to distinguish the two sets, instead of a bool.

Added

  • The new Topology::has_normal_contours and Topology::is_disjoint_tags allow for detecting some no-op (or approximate no-op) situations.
