magic.DetectFormat returns an imagerequest.Format. ValidateMagicBytes returns the format it checked against the upstream Content-Type. The cache reads a cached source's format from its file's first bytes, as it reads a variant's. The proxy hands the format to Process. Process refuses a format that is not a source format, and input libvips would load with another loader, such as an SVG passing as AVIF. Format.MIMEType declares each MIME string once, and the fetcher, the cache's variant read and the Accept matching use it. magic.MIMEType, magic.ImageFormat, MIMEToImageFormat, magic's SVG detection, detectFormat, formatFromString, FormatToMIME and Result.InputFormat are gone.
