Detailed Description

2D Node base class for scene graph.

• Supports hierarchical transformations (position, rotation, scale).
• Manages child nodes and parent-child relationships.
• Handles visibility and z-index for rendering order.
• Provides lifecycle methods: ready(), process(), draw(), input().
