Add a custom Wayland protocol (wayray_wm_v1) that allows external
window manager processes to control layout, focus, and keybindings
in the WayRay compositor, inspired by River's two-phase transaction
model.
New crates:
- wayray-wm-protocol: Wayland protocol XML + generated server/client
bindings via wayland-scanner for four interfaces (manager, window,
seat, workspace)
- wr-wm-tiling: Reference BSP tiling WM demonstrating the protocol
Compositor changes:
- WindowManager trait + WmState coordinator abstracts WM behavior
- Built-in floating WM (centered windows, click-to-focus, z-ordering)
- Protocol server with GlobalDispatch/Dispatch for all interfaces
- Hot-swap (replaced event) and crash resilience (fallback to built-in)
- new_toplevel delegates to WM instead of hardcoding 800x600 at (0,0)
- WM render phase integrated into headless frame pipeline
renderer_gl and backend_winit pulled in backend_egl, which changed the
ImportAll blanket impl to require ImportEgl — a trait PixmanRenderer
doesn't implement. This caused render_output to silently skip client
surface compositing (only the clear color rendered).
Fix: move renderer_gl and backend_winit behind a "winit" cargo feature.
Default build uses only renderer_pixman, which satisfies ImportAll via
the simpler ImportMemWl + ImportDmaWl blanket impl.
Winit backend: cargo build -p wrsrvd --features winit
Headless (default): cargo build -p wrsrvd
Implement QUIC networking for wrsrvd (server) and wrclient (client) using
quinn over rustls with self-signed certificates. Three logical channels:
control (bidirectional), display (server->client unidirectional), and
input (client->server unidirectional).
Server runs tokio in a background thread, communicating with the compositor
via std::sync::mpsc channels. Client exposes an async connect() API that
returns a ServerConnection with methods for sending input and receiving
frames.
Key design note: quinn streams are lazily materialized -- accept_bi/
accept_uni on the peer won't resolve until data is written. The handshake
protocol accounts for this by having each side write immediately after
opening streams.
Restructure wrsrvd to support two backends: a headless PixmanRenderer
(default) for running without a display server, and the existing Winit
backend (via --backend winit). The render logic is split into per-backend
modules, and the old render.rs is removed.
