Module wayland 

Wayland Compositor

Implements the Wayland display protocol for VeridianOS.

Wayland Overview

Wayland is a modern replacement for X11, designed for:

• Direct rendering: Clients draw directly to surfaces
• Asynchronous updates: No blocking on server
• Security: No global coordinate space, isolated clients
• Efficiency: Minimal data copies, GPU acceleration

Core Concepts

• Display: Connection to compositor
• Surface: Renderable area
• Buffer: Pixel data attached to surface
• Compositor: Window manager
• Shell: Desktop interface (xdg-shell)

Protocol types and dispatch infrastructure retained for completeness.
