Called after the interaction receives a new UIPointerRegion from pointerInteraction:regionForRequest:defaultRegion:.

Parameters:

interaction - This UIPointerInteraction.

region - The UIPointerRegion for which a style is being requested.

Returns:

A UIPointerStyle describing the desired hover effect or pointer appearance for the given UIPointerRegion.
