1//! Thin helpers over Godot's main `RenderingDevice`.
2//!
3//! Every function here must run on the **render thread** (the buffer RIDs we
4//! touch belong to the global device) — callers go through
5//! `RenderingServer::call_on_render_thread`, CEL-58 style.

13/// as `attr_w` to recover 2-D texel coords from a linear index.
