/**
 * This directive is used to set specify on which window segment the container
 * should be placed on multi screen devices.
 *
 * When used on a single screen device, no layout change (CSS) is added.
 * Only devices with up to two screen are currently supported, meaning that the
 * window segment value must be either 0 or 1.
 *
 * This directive can only be used within a {@link SplitLayoutDirective}.
 * If {@link SplitLayoutMode} is set to `absolute`, you can assign multiple
 * container element to the same window segment.
 *
 * Note that if you have set the read direction to Right-To-Left mode (`rtl`)
 * in CSS, the first segment will be the rightmost one.
 *
 * If the {@link WindowOrder} option is set to {@link WindowOrder.Reverse},
 * the window segments order will be reversed in horizontal spanning mode.
 *
 * @example
 * <div fdSplitLayout="grid">
 *              <section fdWindow="0">Will be displayed on first screen</section>
 *              <section fdWindow="1">Will be displayed on second screen (if available)</section>
 * </div>
