/**
 * A SpineGameObject is a Phaser {@link GameObject} that can be added to a Phaser Scene and render a Spine skeleton.
 *
 * The Spine GameObject is a thin wrapper around a Spine {@link Skeleton}, {@link AnimationState} and {@link AnimationStateData}. It is responsible for:
 * - updating the animation state
 * - applying the animation state to the skeleton's bones, slots, attachments, and draw order.
 * - updating the skeleton's bone world transforms
 * - rendering the skeleton
 *
 * See the {@link SpinePlugin} class for more information on how to create a `SpineGameObject`.
 *
 * The skeleton, animation state, and animation state data can be accessed via the repsective fields. They can be manually updated via {@link updatePose}.
 *
 * To modify the bone hierarchy before the world transforms are computed, a callback can be set via the {@link beforeUpdateWorldTransforms} field.
 *
 * To modify the bone hierarchy after the world transforms are computed, a callback can be set via the {@link afterUpdateWorldTransforms} field.
 *
 * The class also features methods to convert between the skeleton coordinate system and the Phaser coordinate system.
 *
 * See {@link skeletonToPhaserWorldCoordinates}, {@link phaserWorldCoordinatesToSkeleton}, and {@link phaserWorldCoordinatesToBoneLocal.}
