 * Loads an equirectangular image, picking the loader by file extension, or by
 * content for a `data:` URL, which has none (the bundled default HDR is one).

 * `.hdr` and `.exr` stay linear, everything else goes through the texture
 * loader and is tagged sRGB. The extension is read from the path only, so a
 * query or hash does not hide it. The caller owns the result.
 *
 * @param url - Where the image lives.
 * @returns The texture, mapped as an equirectangular image.
