List all active pointers controlled by this HoverChain.
A copy of each pointer is maintained to pass to event handlers. While iterating,
only one version will be passed of each pointer: if while drawing,
the "armed" copy is used, otherwise the regular versions will be returned.
The above distinction makes it possible for nodes to process the same pointers
as they're given in event handlers, while outsiders are given the usual versions.
