Description
Used to enable interlacing for a given MIME type, up to a given pixel limit (interlacing is relatively expensive).
For basic information on what interlacing is, see http://pooyak.com/p/progjpeg/.
Currently supported MIME types in core: image/jpeg, image/png, image/gif.
Interlacing will be done via ImageMagick, or for jpeg/png via VIPS if Extension:VipsScaler is enabled.
