Currently, the spine-godot runtime does not provide a specific Control node for Spine animations to be used directly as UI objects. However, you can use the existing SpineSprite node within a Control node by adding it as a child. This allows you to integrate Spine animations into your UI, although it may require some additional setup to ensure proper alignment and interaction within the UI layout.

Here's a basic example of how you can add a SpineSprite to a Control node:

1. Create a Control node in your scene.
2. Add a SpineSprite node as a child of the Control node.
3. Assign the SkeletonDataResource to the SpineSprite node.
4. Adjust the position and size of the SpineSprite to fit within the Control node.

This setup allows you to use Spine animations within the UI, leveraging the existing SpineSprite functionality.
