Volto add-on: Window resize helper

Usage

After you add this add-on to your project, the screen state is available as a global state in redux store.

!! Note that the values inside of screen object are related to the device / display sizes, not the browser sizes.

The layoutViewport object contains the sizes of the browser with scrollbars.

The page object contains the sizes of the browser without scrollbars. Note that the scrollbarWidth is available in page.scrollbarWidth.

The content object contains the width and offsets of content-area element (where blocks are rendered). This is useful for when you want to determine the widths of toolbar / sidebar and height of whatever is rendered above content-area.

The visualViewport object contains the sizes of the visual viewport. Note that the visual viewport is changing when zoomed in / out.
