winscripter	27a848cd25	Add DCT, transpose, and performance improvements - Add a slice & assert to JxlHuffmanDecoder alphabetSize to allocate at most 256 items - Use [0, 0] instead of stackalloc[2] followed by Clear() in JxlAnsReader - Add assert to Butteraugli ComputeKernel method & use float for Butteraugli Wmul & use InlineArray - Add transpose. - Note: transpose is scalar, it doesn't support SIMD yet - Add shared constants & file signature - Improve while loop in JxlImageOperations.Mirror - Floating-point Discrete Cosine Transform (1D and 2D) - Add an inline array of 2 items Source files implemented from libjxl with this commit: - dct-inl.h - dct_block-inl.h - transpose-inl.h	3 weeks ago
