A JPEG XL source is accepted, and orig of one is JPEG XL. The format jxl works in plain and encrypted URLs and on the generator page, served as image/jxl; auto chooses it first when Accept names image/jxl. govips sends libvips a JPEG XL distance, which overrides the quality, so q is turned into a distance, keeping 100 lossy. govips cannot have libvips strip metadata from JPEG XL, so it is removed from the image before saving; libvips 8.16 and later still add an EXIF block of their own, with nothing from the source. The conversion to sRGB moved ahead of the format switch, and a CMYK image with no ICC profile is converted to sRGB too, as libvips cannot save CMYK as JPEG XL. Model: opus-5-5
