//! VarDCT (lossy) encoder for JPEG XL.
//!
//! Variable-DCT encoding transforms image blocks using DCT of various sizes,
//! quantizes coefficients with perceptual weighting, and entropy codes the result.
//!
//! Supports 19 of 27 DCT strategies (all that libjxl evaluates through effort 9),
//! Huffman or ANS entropy coding, custom coefficient ordering, LZ77 backward
//! references, adaptive quantization, chroma-from-luma, gaborish inverse,
//! noise synthesis, and butteraugli-guided rate control.
