// Enable SVE2 intrinsics when the `nightly-sve2` feature is active.
// This is a no-op on stable (the cfg is false); the feature gate only fires
// on nightly when a caller explicitly opts in with `--features nightly-sve2`.

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