Crate cvkg_compositor 

CVKG Compositor

Retained-mode layer orchestration engine for the CVKG UI framework.

The compositor sits between cvkg-vdom and cvkg-render-gpu, providing:

• Material Routing: Organizes draw calls into GPU pass buckets (scene, glass, overlay).
• Damage Tracking: Tracks which layers changed to avoid re-recording static content.
• Layer Orchestration: Maintains a retained LayerTree with Z-sorting and hierarchy.
