Module text 

Vello CPU glyph rendering backend.

Provides GlyphAtlas (atlas backed by per-page Pixmaps) and the GlyphRenderer implementation for RenderContext that rasterises glyphs into CPU-accessible pixel buffers.

The key difference from the hybrid backend is that atlas pages are owned as Arc<Pixmap>s here, so the CPU renderer can read pixels directly without any GPU upload step.
