It produces multiple downscaled outputs from a single input frame in one fused pass, which avoids the redundant memory traffic of running an external scaler per output size. Features: - Power-of-two and thirds (1/2, 1/3, 1/4, 2/3, ...) downscale ratios and integer upscale, all in a single pass over the source. - 8-bit SDR (I420, NV12) and 10-bit HDR (I010, P010, I210, P210) pixel formats. - HDR-to-SDR tonemapping with PQ (SMPTE 2084) and HLG transfer curves, and a custom-LUT path for application-supplied curves. - Hand-tuned SIMD kernels: AVX2 on amd64, NEON on aarch64. Detection is at runtime; falls back to a portable scalar path.
