v0.5.2

What's Changed

Performance Improvements

• perf(render): 66% speedup on 600 dpi bilevel pages (#105)
  • Pixmap::new: replaced per-pixel push loop with bulk fill — 18 ms → 0.8 ms (−95%) for a 2649×4530 buffer
  • composite_bilevel: row-slice writes + rayon par_chunks_mut under --features parallel
  • Skip apply_gamma for pure bilevel pages (0/255 values, gamma is a mathematical no-op)
  • Parallel Y/Cb/Cr wavelet reconstruction via rayon::join under --features parallel
  • Sparse 600 dpi bilevel page: 42.7 ms → 14.5 ms — now within 19% of libdjvulibre (was 3.5× slower)
