Enum ImageHeader 

pub enum ImageHeader {
    Unknown,
    Unreadable,
    Size {
        width: u32,
        height: u32,
        frames: u32,
    },
}

What a whole image’s bytes say before any decode (VAPP-103): no known image format, a raster (PNG, JPEG, GIF, WebP, BMP) or SVG whose size cannot be read, or its size and image_frames. Every renderer’s pixel cap reads this ONE answer (the natives through the FFI).
