* 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.}

* The scene's {@link GameObjectCreator} (`Scene.make`) gets these additional functions:
* * `spine(config: SpineGameObjectConfig)`: creates a new {@link SpineGameObject} from the given configuration object.
*
* The plugin has additional public methods to work with Spine Runtime core API objects:
* * `getAtlas(atlasKey: string)`: returns the {@link TextureAtlas} instance for the given atlas key.
* * `getSkeletonData(skeletonDataKey: string)`: returns the {@link SkeletonData} instance for the given skeleton data key.
* * `createSkeleton(skeletonDataKey: string, atlasKey: string, premultipliedAlpha: boolean = true)`: creates a new {@link Skeleton} instance from the given skeleton data and atlas key.
* * `isPremultipliedAlpha(atlasKey: string)`: returns `true` if the atlas with the given key has premultiplied alpha.
