feat: Implement Object UI

[Bli-AIk]

🔗 Is your feature request related to a specific issue?

The MooaLewaUI framework, with its XamlX integration, defines an abstract UI structure. However, it needs a concrete rendering backend to actually display this UI. One desirable backend is a system that renders UI elements as standard game objects within the world.

---

💡 Feature Description

Create an "Object UI" rendering backend for MooaLewaUI. This backend will translate the abstract UI control tree (defined in XAML or code) into a hierarchy of game objects using sprites, meshes, and other standard engine components.

• Expected outcome or effect: Rendering of the UI as standard game objects within the game scene, allowing for diegetic or 3D UI.
• Specific implementation ideas: The following definitions are for reference only and are subject to change. Implementation could include:
  • A set of ObjectButton, ObjectTextBlock, etc., classes that implement the abstract UI control interfaces.
  • These classes will be responsible for creating and managing the corresponding visual game objects.
  • An ObjectUIRenderer would be responsible for instantiating these objects based on the UI tree provided by the XAML loader.
• Usage scenarios or benefits:
  • Creating in-world computer terminals or floating health bars.
  • Building UIs that can be affected by in-game physics or lighting.
  • A flexible, engine-agnostic default renderer for the framework.

📝 Additional Information

This backend should be the primary, engine-independent implementation, while others (like the UGUI backend) will be engine-specific.
