How snowdeenn/learn_wgpu works

Velum is a Rust 2D rendering and scene library for applications. An application builds a scene with typed render data and ordered render passes; the renderer executes those passes against backend resources and targets. The repository also provides particle effects, post-processing, camera/input, text and debug tooling. Relationships among unsampled modules are limited to dependencies named in the source index; the README is empty, so broader capability descriptions are based on the source tree and sampled code.
