Follows #6651. When the refits of a closed subpath enclose no area,
Simplify splits its curves until straight lines between the pieces
enclose one. That split stopped at 65,536 pieces in all, and a loop
with many anchors then came back as the flat refit, with no outline.
- Only curved segments are split; line segments stay one piece each.
- When no split within the limits encloses an area, the loop stays as
it is. With Convert to Straight Lines, each curved segment becomes
the lines between its samples instead.
Follows #6614. When a closed subpath's refit in two and in three parts is
still lines that enclose no area, for example an S curve closed by a
straight edge whose cut points all lie on that edge, Simplify now splits
each segment in 2, 4, 8 and so on (up to 1,024 pieces, 65,536 in all)
until every piece is within the tolerance of the line between its ends
and those lines enclose an area. With Convert to Straight Lines those
lines are the result; without it the subpath stays as it is. A subpath
whose points are all in line keeps the refit's lines, so its extra
anchors are still removed. Lines count as enclosing no area when every
point is within 1e-6 pt of one line.
A closed subpath that refits to a single curve has one anchor, which is
not a subpath, so Simplify dropped it: a small circle inside a compound
path was lost and the result ended hundreds of points from the original,
and a small closed path on its own came out empty. Such a subpath is now
refitted in two parts, cut at the point farthest from its start, or in
three when two parts would still enclose no area (two lines that retrace
each other with Convert to Straight Lines). A closed subpath of a single
segment stays as it is.
Add Anchor Points builds the new anchor list in one pass, Swatch Library add looks names up in sets, full_documents dedups placed keys with a set, width profile lookups and mark insertion use binary search, and the symbolism tools cap and thin the previews of a long drag as Liquify does.
normalize_bez ran the sweep without the catch_unwind guard that Sweep::new has,
so an outline_stroke width of 1e200 or more with a round join panicked inside
linesweeper (Left == Ish). The panic is now a Degenerate error and the art is
left unchanged. Adds hostile-number tests for the pathops edit, stroke and
offset functions.
Found while testing crates/pathops/src/edit.rs:342-364 (smooth_level calls smooth_seam after the fit)

Offset Path outlined an open path on both sides, so a shape whose last
anchor sits on its first came out as a ring with a hole. Such a path is
now offset as a closed shape: its last anchor merges into its first,
which takes the last anchor's in-handle, with the same 1e-6 test that
Object › Path › Join uses for one path (crates/engine/src/cmd/path.rs).
The Offset Path effect calls the same function.
* CI: line tables only for workspace crates, no debug info for dependencies
* CI: one integration-test binary per crate
Each crate's tests/*.rs files become modules of tests/it/main.rs. Files that change
process-wide state (Color Settings, the font database, installed plug-ins, the working
directory), the fuzz sweeps and the test targets the Affinity corpus workflow names stay
their own binaries.
* Docs: name the integration tests' new paths
* CI: xtask test with nextest and doctests, one wasm check, clippy --keep-going
cargo xtask ci runs the tests with cargo nextest (cargo test when it is not installed),
builds them with --lib --bins --tests, runs the doctests as their own step, and checks
the wasm crates in one cargo check --keep-going call.
