Describes the direction of a scrolling action.
The values in this enumeration are used by the AccessibilityNode.scrolled event, which is sent
when a screen reader user performs a scrolling action.
Each direction describes how the visible region of the content should move: AccessibilityScrollDirection.Up and
AccessibilityScrollDirection.Left should move the visible region toward the start of the content, revealing the content
above or to the left of it, and AccessibilityScrollDirection.Down and AccessibilityScrollDirection.Right should move it toward the end.
AccessibilityScrollDirection.Forward and AccessibilityScrollDirection.Backward should scroll to the next and previous portion of the
content along its main scrolling axis.
