Vello Rust 2D renderer

Document status: reviewed. Canonical source.

Summary

Vello is a Rust GPU-compute-centric 2D renderer using wgpu. Its scene abstraction covers vector shapes, images, gradients and text-oriented drawing, while current releases still document evolving APIs and some incomplete effect/glyph areas.

NUIF relevance

Use Vello as an implementation experiment, not a normative dependency. Maintain a renderer trait and conformance raster path so the draft specification’s visual semantics remain independent of Vello’s evolution.
