// EntityEvent contains information about component changes to an [Entity].
//
// To receive change events, register a function func(e *EntityEvent) with [World.SetListener].
//
// Events notified are entity creation, removal and changes to the component composition.
// Events are emitted immediately after the change is applied.
//
// Except for removed entities, events are always fired when the [World] is in an unlocked state.
// Events for removed entities are fired right before removal of the entity,
// to allow for inspection of it's components.
// Therefore, the [World] is in a locked state during entity removal events.
//
// Events for batch-creation of entities using a [Builder] are fired after all entities are created.
// For batch methods that return a [Query], events are fired after the [Query] is closed (or fully iterated).
// This allows the [World] to be in an unlocked state, and notifies after potential entity initialization.
//
// Note that the event pointer received by the listener function should not be stored,
// as the instance behind the pointer might be reused for further notifications.
