I modified STB-Image's JPEG codec to render JPEG files directly to 32-bit floating-point pixels to reduce color banding when editing images.
Coincidentally, this can recompress JPEGs much more consistently, eventually stabilizing when the recompression gives an image the exact same compressed file.
