An resolver for pointer signal events.
Objects interested in a PointerSignalEvent should register a callback to be called if they should handle the event. The resolver's purpose is to ensure that the same pointer signal is not handled by multiple objects in a hierarchy.
Pointer signals are immediate, so unlike a gesture arena it always resolves at the end of event dispatch. The first callback registered will be the one that is called.
PointerSignalEvent event, PointerSignalResolvedCallback callback) → void
