//! An OpenGL bindings generator. It defines a function named `generate_bindings` which can be
//! used to generate all constants and functions of a given OpenGL version.
//!
//! # Example
//!
//! In `build.rs`:
//!
//! ```no_run
//! extern crate gl_generator;
//!
//! use gl_generator::{Registry, Api, Profile, Fallbacks, GlobalGenerator};
//! use std::env;
//! use std::fs::File;
//! use std::path::Path;
//!
//! fn main() {
//!     let dest = env::var("OUT_DIR").unwrap();
//!     let mut file = File::create(&Path::new(&dest).join("gl_bindings.rs")).unwrap();
//!
//!     Registry::new(Api::Gl, (4, 5), Profile::Core, Fallbacks::All, [])
//!         .write_bindings(GlobalGenerator, &mut file)
//!         .unwrap();
//! }
//! ```
//!
//! In your project:
//!
//! ```ignore
//! include!(concat!(env!("OUT_DIR"), "/gl_bindings.rs"));
//! ```
//!
//! # About EGL
//!
//! When you generate bindings for EGL, the following platform-specific types must be declared
//!  *at the same level where you include the bindings*:
//!
//! - `khronos_utime_nanoseconds_t`
//! - `khronos_uint64_t`
//! - `khronos_ssize_t`
//! - `EGLNativeDisplayType`
//! - `EGLNativePixmapType`
//! - `EGLNativeWindowType`
//! - `EGLint`
//! - `NativeDisplayType`
//! - `NativePixmapType`
//! - `NativeWindowType`
//!
