		 * Scaling options for preview images
		 *
		 * For responsive images, several preview images of different sizes are
		 * generated. This setting controls how many preview images are generated,
		 * what's their maximum width and height and if the given width/height is
		 * enforced by cropping images that doesn't fit.
		 *
		 * The setting must consist of a list image size definitions like:
		 *
		 *  [
		 *    ['maxwidth' => 240, 'maxheight' => 320, 'force-size' => true],
		 *    ['maxwidth' => 720, 'maxheight' => 960, 'force-size' => false],
		 *    ['maxwidth' => 2160, 'maxheight' => 2880, 'force-size' => false],
		 *  ]
		 *
		 * "maxwidth" sets the maximum allowed width of the image whereas
		 * "maxheight" does the same for the maximum allowed height. If both
		 * values are given, the image is scaled proportionally so it fits into
		 * the box defined by both values. In case the image has different
		 * proportions than the specified ones and "force-size" is false, the
		 * image is resized to fit entirely into the specified box. One side of
		 * the image will be shorter than it would be possible by the specified
		 * box.
		 *
		 * If "force-size" is true, scaled images that doesn't fit into the
		 * given maximum width/height are centered and then cropped. By default,
		 * images aren't cropped.
		 *
		 * The values for "maxwidth" and "maxheight" can also be null or not
		 * used. In that case, the width or height or both is unbound. If none
		 * of the values are given, the image won't be scaled at all. If only
		 * one value is set, the image will be scaled exactly to the given width
		 * or height and the other side is scaled proportionally.
		 *
		 * You can also define different preview sizes for different domains (e.g.
		 * for catalog images) and for different types (e.g. catalog stage images).
		 * Use configuration settings like
		 *
		 *  mshop/media/manager/previews/previews/<domain>/
		 *  mshop/media/manager/previews/previews/<domain>/<type>/
		 *
		 * for example:
		 *
		 *  mshop/media/manager/previews/catalog/previews => [
		 *    ['maxwidth' => 240, 'maxheight' => 320, 'force-size' => true],
		 *  ]
		 *  mshop/media/manager/previews/catalog/previews => [
		 *    ['maxwidth' => 400, 'maxheight' => 300, 'force-size' => false]
		 *  ]
		 *  mshop/media/manager/previews/catalog/stage/previews => [
		 *    ['maxwidth' => 360, 'maxheight' => 320, 'force-size' => true],
		 *    ['maxwidth' => 720, 'maxheight' => 480, 'force-size' => true]
		 *  ]
		 *
		 * These settings will create two preview images for catalog stage images,
		 * one with a different size for all other catalog images and all images
		 * from other domains will be sized to 240x320px. The available domains
		 * which can have images are:
		 *
		 * * attribute
		 * * catalog
		 * * product
		 * * service
		 * * supplier
		 *
		 * There are a few image types included per domain ("default" is always
		 * available). You can also add your own types in the admin backend and
		 * extend the frontend to display them where you need them.
		 *
		 * @param array List of image size definitions
		 * @category Developer
		 * @category User
		 * @since 2019.07
