Module simd 

SIMD-accelerated hot paths for the rasterizer.

All SIMD code is gated behind #[cfg(target_arch = "x86_64")] and uses runtime feature detection (is_x86_feature_detected!) so the binary runs correctly on machines that lack the required extensions.

Sub-modules

• aa_coverage — per-pixel AA coverage counts (aa_coverage_span)
• blend — solid-colour fill (blend_solid_rgb8, blend_solid_gray8)
• composite — AA per-pixel blend (composite_aa_rgb8_opaque)
• glyph_unpack — 1-bit-per-pixel mono glyph expansion (unpack_mono_row)
