rein 0.1.0

//! Rein 3D Rendering Library
//!
//! A three-d style 3D rendering library built on wgpu.
//!
//! # Architecture
//!
//! The library is organized into layers:
//!
//! 1. **context** - Core wgpu wrapper (Device, Queue)
//! 2. **core** - Mid-level abstractions (buffers, textures, pipelines)
//! 3. **renderer** - High-level rendering (cameras, materials, objects, lights)
//! 4. **window** - Window management with winit (optional, feature = "window")
//! 5. **gui** - Text rendering (optional, feature = "gui")
//! 6. **urdf** - URDF robot model support
//!
//! # Example
//!
//! ```no_run
//! use rein::{Window, WindowSettings, FrameOutput};
//! use rein::renderer::{Camera, OrbitControl};
//! use rein::urdf::RobotModel;
//! use rein::core::ClearState;
//! use glam::Vec3;
//!
//! fn main() -> anyhow::Result<()> {
//!     let window = Window::new(WindowSettings::default().title("Robot Viewer"))?;
//!
//!     // State will be initialized in the render loop
//!     struct State {
//!         camera: Camera,
//!         control: OrbitControl,
//!         robot: Option<RobotModel>,
//!     }
//!
//!     // ...
//!     Ok(())
//! }
//! ```
