Marco Allegretti 43269c9be1 feat(compositor): render pointer cursor from CursorImageStatus::Surface 
When a Wayland client calls wl_pointer.set_cursor, render the cursor
surface at pointer_location using render_elements_from_surface_tree.

Changes in render_output:
- Collect output_geo, pointer_location, cursor_status before the inner
 rendering block (avoids borrow conflict with space+drm destructure)
- Build cursor elements as Vec<SpaceRenderElements<_, WaylandSurfaceRenderElement<_>>>
 via render_elements_from_surface_tree with Kind::Cursor; hotspot is
 read from CursorImageSurfaceData on the cursor wl_surface
- Cursor elements prepend space elements (highest z-index first, matching
 render_elements_for_output sort order descending by z_index)
- CursorImageStatus::Hidden / Named: no cursor element emitted

New imports: SpaceRenderElements, CursorImageStatus, CursorImageSurfaceData,
render_elements_from_surface_tree, Kind, Scale, with_states

Hardware cursor plane deferred requires DRM cursor plane API audit.

README.md

WEFT OS

WEFT OS is a Linux-based operating system effort built around a Smithay compositor, a Servo-rendered system shell, and a Wasmtime-based application runtime.

Current repository scope

This repository currently contains:

  • the baseline Rust workspace
  • public engineering documentation derived from the authoritative blueprint
  • initial design documents for the shell protocol boundary and the Wasm–Servo channel
  • local and CI validation paths for repository bootstrap work

It does not yet contain a compositor, shell, or application runtime implementation.

Source of truth

The authoritative technical reference for this repository is docu_dev/WEFT-OS-COMPREHENSIVE-BLUEPRINT.md.

Historical blueprint documents exist in docu_dev/, but they are not implementation authority where they conflict with the comprehensive blueprint.

Privacy boundary

docu_dev/ is a private coordination area used during development. It is intentionally ignored by git and is not part of the tracked public repository surface.

Development model

  • Primary development host: Windows workstation
  • Primary runtime target: Linux VM or QEMU guest
  • Core system language: Rust

Validation

On Windows PowerShell:

./infra/scripts/check.ps1

On Linux:

./infra/scripts/check.sh
