+ *
+ * Each item should contain data that you need to generate slide
+ * (for image slide it would be src (image URL), width (image width), height, srcset, alt).
+ *
+ * If these properties are not present in your initial array, you may "pre-parse" each item from itemData filter.
+ *
+ * @prop {number} bgOpacity
+ * Background backdrop opacity, always define it via this option and not via CSS rgba color.
+ *
+ * @prop {number} spacing
+ * Spacing between slides. Defined as ratio relative to the viewport width (0.1 = 10% of viewport).
+ *
+ * @prop {boolean} allowPanToNext
+ * Allow swipe navigation to the next slide when the current slide is zoomed. Does not apply to mouse events.
+ *

+ * Slide area padding (in pixels).
+ *
+ * @prop {(viewportSize: Point, itemData: SlideData, index: number) => Padding} [paddingFn]
+ * The option is checked frequently, so make sure it's performant. Overrides padding option if defined. For example:
+ *
+ * @prop {number | false} hideAnimationDuration
+ * Transition duration in milliseconds, can be 0.
+ *
+ * @prop {number | false} showAnimationDuration
+ * Transition duration in milliseconds, can be 0.
+ *
+ * @prop {number | false} zoomAnimationDuration
+ * Transition duration in milliseconds, can be 0.
+ *
+ * @prop {string} easing
+ * String, 'cubic-bezier(.4,0,.22,1)'. CSS easing function for open/close/zoom transitions.
+ *
+ * @prop {boolean} escKey
+ * Esc key to close.
+ *
+ * @prop {boolean} arrowKeys
+ * Left/right arrow keys for navigation.
+ *

+ *
+ * @prop {boolean} returnFocus
+ * Restore focus the last active element after PhotoSwipe is closed.
+ *
+ * @prop {boolean} clickToCloseNonZoomable
+ * If image is not zoomable (for example, smaller than viewport) it can be closed by clicking on it.
+ *
+ * @prop {ActionType | ActionFn | false} imageClickAction
+ * Refer to click and tap actions page.

+ * Delay before the loading indicator will be displayed,
+ * if image is loaded during it - the indicator will not be displayed at all. Can be zero.
+ *
+ * @prop {string} indexIndicatorSep
+ * Used for slide count indicator ("1 of 10 ").
+ *
+ * @prop {(options: PhotoSwipeOptions, pswp: PhotoSwipeBase) => Point} [getViewportSizeFn]
+ * A function that should return slide viewport width and height, in format {x: 100, y: 100}.
+ *
+ * @prop {string} errorMsg
+ * Message to display when the image wasn't able to load. If you need to display HTML - use contentErrorElement filter.
+ *
+ * @prop {[number, number]} preload
+ * Lazy loading of nearby slides based on direction of movement. Should be an array with two integers,
