+ * * `spine(x: number, y: number, dataKey: string, atlasKey: string, boundsProvider: SpineGameObjectBoundsProvider = SetupPoseBoundsProvider())`:
  *    creates a new {@link SpineGameObject} from the data and atlas at position `(x, y)`, using the {@link BoundsProvider} to calculate its bounding box. The object is automatically added to the scene.

  * 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.
