Rust: Add a Glide renderer (2D only for now) This is an experiment for a Rust renderer, iterating over the Python data using pyo3. It requires --feature=glide to be passed to cargo build, doesn’t support NPOT textures, text rendering, the background, or even msg faces, some of that may come in a future changeset.
