HoverPointer used to perform the action. Its most important property is the scroll field, but some nodes may also filter based on the pointer's state.
True if the node can accept the scroll value in part or in whole, false if the motion would have no effect.
Determines whether this node can accept scroll input and if the input can have visible effect. This is usually determined by the node's position; for example a container node already scrolled to the bottom cannot accept further vertical movement down.
This property is used to determine which node should be used to accept scroll. If there's a scrollable container nested in another scrollable node, it will be chosen for scrolling only if the scroll motion can still be performed. On the other hand, if the intent is specifically to block scroll motion (like in a modal window), this method should always return true.
Note that a node "can scroll" even if it can only accept part of the motion. If the scroll would have the node scroll beyond its maximum value, but the node is not already at its maximum, it should accept the input and clamp the value.
