* `FilterLabel(labels)`: filters to only objects that match these labels.
* `FilterSelects(labels)`: filters to only objects that **select** these labels. An empty selector matches everything.
* `FilterSelectsNonEmpty(labels)`: filters to only objects that **select** these labels. An empty selector matches nothing.
* `FilterGeneric(func(any) bool)`: filters by an arbitrary function.
