From 1d4662b454a3581742efa264fc59545605f2b72a Mon Sep 17 00:00:00 2001 From: bot_apk Date: Thu, 12 Mar 2026 21:33:30 +0000 Subject: [PATCH] feat: implement video compositor review recommendations - Add debug assertions for Y-plane raw pointer aliasing in convert.rs - Clarify AVX2 packus cross-lane comments in simd_x86_64.rs - Shrink ConversionCache entries when resolution decreases (>2x) - Add max-entry bound (64) to FONT_CACHE with eviction - Validate decoded image dimensions against max_canvas_dimension - Fix fragile sleep-based test in pixel_convert.rs - Derive Copy for Rect and BlitRect, remove unnecessary clones - Remove compositor/pixel_ops/mod.rs re-export shim - Extract shared bench_utils module for generate_rgba_frame - Use font.metrics() instead of rasterize() for measurement - Migrate compositor_only and pixel_convert benchmarks to criterion Signed-off-by: Devin AI Co-Authored-By: Staging-Devin AI
