Vendored third-party crates

Copies of third-party crates that SolveCraft builds with local fixes, wired in with [patch.crates-io] in the workspace Cargo.toml. They keep their own licence; changed lines are marked SolveCraft: in the source.

truck-shapeops 0.4.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)

Changes:

• transversal/intersection_curve/mod.rs: reject empty/single-point polylines and collapsed or non-finite segments before endpoint indexing and normalization. A hidden constructor re-export lets the kernel workspace tests exercise the actual vendored code.
• transversal/integrate/mod.rs: mesh both shells with robust_triangulation (faces made by earlier booleans have boundaries that lie on their surface only within tolerance).
• transversal/divide_face/mod.rs: when projecting a loop onto a face's surface, fall back to the nearest parameter when the exact search fails (intersection curves are approximations).
• transversal/integrate/mod.rs: the result's shells and faces keep the order of the shell they come from (truck's connected components followed hash order of face addresses, so a boolean's faces came out in a different order on every run).
• lib.rs: tr! reports where an operation gives up when SHAPEOPS_TRACE is set; compiler warnings no longer fail the build.
• Face and edge history (transversal/history.rs, new): and_with_history / or_with_history also return, for each face of the result (in face_iter order), the operand face it is a region of and whether it is that face unchanged, and for each edge (distinct edges in order of first use along the faces) the operand edge it is (a piece of) or the two operand faces whose intersection made it. The code that creates faces and edges records them as it goes: divide_face (face pieces), loops_store (intersection edges, split edges, edges rebuilt on a moved vertex), across the passes that fold in the operands' extra shells. and / or are wrappers that drop the history; the *_with_history forms return the same solid with the history as an Option (None where a face or edge went unrecorded).

truck-stepio 0.3.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)

Only the writer (out) is used; SolveCraft reads STEP with its own reader.

Changes:

• out/geometry.rs: an INTERSECTION_CURVE's second surface was written at the first surface's entity index, so every boolean-made edge produced duplicate entity ids.
• out/geometry.rs: surfaces of revolution carry the right same_sense for inverted and mirrored revolutions (ISO 10303-42 parameterises them by angle then profile, so their normal is the opposite of truck's; a mirroring transform reverses it again), and the modeling-surface wrapper passes the revolution's sense through instead of always true.
• lib.rs: compiler warnings no longer fail the build. Example and test targets are dropped (their sources are not vendored).

truck-meshalgo 0.4.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)

Changes:

• tessellation/triangulation.rs: the inside test of a face's boundary skips loops whose parameter box is clear of the point (it tested every segment of every loop, so a face with hundreds of holes meshed in quadratic time).
• tessellation/triangulation.rs: meshed faces and edges are built unchecked: faces whose loop runs along a seam edge both ways and closed edges (a full circle on one vertex) are valid, but the debug-build checks rejected them (debug builds could not mesh them).
• tessellation/triangulation.rs: parameter searches that land outside a surface's bounded, non-periodic domain are rejected (a hinted B-spline search can run off and extrapolate to thousands of parameter units, and meshing that grid never finishes); the last-resort nearest search is clamped into the domain.
• tessellation/triangulation.rs, bounded work (hostile files must not hang): edge polylines and surface grids come from our own bounded divisions (at most 20 000 points per edge, a grid budget per face shared out of 10 million points per shell, 24 refinement rounds; a point that does not evaluate counts as flat instead of recursing). Surface grids refine only the direction that bends, and a ruling left undivided gets cells comparable to the other direction (long triangles from a trim loop to the grid's far ends cut through cylinders).
• lib.rs: compiler warnings no longer fail the build. Example, test and bench targets are dropped (their sources are not vendored).

matext4cgmath 0.1.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/matext4cgmath)

truck-geometry uses it for a matrix's operator norm (an intersection curve scales its tolerance by it whenever it is moved).

Changes:

• solver.rs: the Newton refinement of cubic and quartic roots stops after 100 steps. Near a double root it could cycle forever: moving a body whose edges a boolean made (the retries move both bodies and the result back) hung the app.
• lib.rs: compiler warnings no longer fail the build. Test targets are dropped (their sources are not vendored).

egui-wgpu 0.36.2 (MIT OR Apache-2.0, Emil Ernerfeldt and contributors)

Original package sources from https://github.com/emilk/egui/tree/0.36.2/crates/egui-wgpu, with both original licence texts retained. No images or bundled documentation are copied.

SolidCraft changes:

• src/lib.rs: use 1x MSAA on the selected OpenGL adapter before creating pipelines, exposing the effective sample count so host paint callbacks can match it.
• src/winit.rs: use that same effective count for depth and resolve attachments.
• Other backends retain requested MSAA, without another adapter or device probe.
