	 * Class name of the used media manager implementation

	 * Each default manager can be replace by an alternative imlementation.
	 * To use this implementation, you have to set the last part of the class
	 * name as configuration value so the manager factory knows which class it
	 * has to instantiate.
	 *
	 * For example, if the name of the default class is
	 *
	 *  \Aimeos\MShop\Media\Manager\Standard
	 *
	 * and you want to replace it with your own version named
	 *
	 *  \Aimeos\MShop\Media\Manager\Mymanager
	 *
	 * then you have to set the this configuration option:
	 *
	 *  mshop/media/manager/name = Mymanager
	 *
	 * The value is the last part of your own class name and it's case sensitive,
	 * so take care that the configuration value is exactly named like the last
	 * part of the class name.
	 *
	 * The allowed characters of the class name are A-Z, a-z and 0-9. No other
	 * characters are possible! You should always start the last part of the class
	 * name with an upper case character and continue only with lower case characters
	 * or numbers. Avoid chamel case names like "MyManager"!

		 * 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
		 *
		 *  controller/common/media/<domain>/previews
		 *  controller/common/media/<domain>/<type>/previews
		 *
		 * for example:
		 *
		 *  controller/common/media/catalog/previews => [
		 *    ['maxwidth' => 240, 'maxheight' => 320, 'force-size' => true],
		 *  ]
		 *  controller/common/media/catalog/previews => [
		 *    ['maxwidth' => 400, 'maxheight' => 300, 'force-size' => false]
		 *  ]
		 *  controller/common/media/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.
