//! 2D offsetting for arc polylines/polygons.
//!
//! # Examples
//!
//! ```rust
//! use togo::prelude::*;
//! use offroad::prelude::*;
//!
//! // Create a simple L-shaped polyline
//! let poly = vec![
//!     pvertex(point(0.0, 0.0), 0.0),    // Start point
//!     pvertex(point(10.0, 0.0), 0.0),   // Horizontal line
//!     pvertex(point(10.0, 10.0), 0.0),  // Vertical line
//! ];
//!
//! // Create default configuration
//! let mut cfg = OffsetCfg::default();
//!
//! // Offset by 2.0 units to the right
//! let offset_polylines = offset_polyline_to_polyline(&poly, 2.0, &mut cfg);
//!
//! // The function returns a vector of polylines
//! assert!(offset_polylines.len() == 1);
//! assert!(offset_polylines[0].len() == 6);
//! ```
//!
//! Check "examples" directory for more usage examples.
