9//! # raster
10//!
11//! Pure software rasterizer for PDF page content — no I/O, no PDF parsing,
12//! no SIMD (Phase 1).
13//!
14//! ## Phase 1 scope
15//! Foundation types only: pixel buffers, path geometry, edge tables, clip
16//! regions, halftone screens, and graphics state. Rendering (pipe, fill,
17//! stroke, image, shading, glyph, transparency) is Phase 2.
18//!
19//! ## Module layout
20//! - [`types`] — raster-local enums and constants (re-exports [`color`] types)
21//! - [`bitmap`] — [`Bitmap<P>`] and [`AaBuf`]
22//! - [`path`] — [`Path`], [`PathBuilder`], Bezier flattening, stroke adjustment
23//! - [`xpath`] — [`XPath`] edge table (flattened, matrix-transformed segments)
24//! - [`scanner`] — [`XPathScanner`] and [`crate::ScanIterator`] (scanline span emission)
25//! - [`clip`] — [`Clip`] (rect + arbitrary path clip stack)
26//! - [`screen`] — [`HalftoneScreen`] (Bayer / stochastic threshold matrix)
27//! - [`state`] — [`GraphicsState`] and [`StateStack`]
28//! - [`pipe`] — compositing pipeline (simple, AA, general; blend modes; Pattern trait)
