//! # glTF Format Constants
//!
//! This module defines standard constant values used throughout the glTF 2.0 specification.
//! These constants represent enumerated values for various glTF properties such as
//! component types, accessor types, buffer targets, texture filtering modes, and more.
//!
//! Using these constants rather than magic numbers ensures consistency with the glTF
//! specification and makes the code more readable and maintainable.
//!
//! For more details on these values, see the official [glTF 2.0 specification](https://www.khronos.org/registry/glTF/specs/2.0/glTF-2.0.html).
//!
//! ## Example
//!
//! ```rust
//! use mesh_tools::constants::{component_type, accessor_type};
//!
//! // When creating an accessor for 3D positions
//! let component_type_value = component_type::FLOAT; // 5126
//! let accessor_type_value = accessor_type::VEC3;    // "VEC3"
//! ```
