Engine-first Cargo workspace for DrawCraft (clean-room Illustrator): - geom: anchor-based path model, shapes, hit testing, snapping - color: colours, paints, gradients, swatches, blend modes, harmonies - doc: persistent Arc document tree, appearance stacks, text model, selection - render: vello_cpu renderer (appearance, gradients, clip groups, blend modes) - text: font DB, harfrust shaping, point/area/path layout - pathops: curve booleans (linesweeper), Pathfinder, offset, simplify - svg: import (usvg) and export - tools: selection/direct/pen/shape tools emitting commands - engine: Session, history with interactions, ~110 commands Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! DrawCraft path operations: booleans (Pathfinder), shape builder regions, offset, outline stroke,
|
|
//! simplify and the other Object → Path commands.
|
|
//!
|
|
//! Booleans are curve-preserving: `linesweeper`'s robust sweep-line works directly on cubic
|
|
//! Béziers, and the pieces it splits curves into are refitted afterwards so results carry few
|
|
//! anchors. See the crate README for the API overview.
