objc2-open-gl 0.3.2

//! # Bindings to the `OpenGL` framework
//!
//! Note that this crate intentionally leaves out the cross-platform parts of
//! the OpenGL API. See crates like `gl` or `gl_generator` for that instead.
//!
//! See [the OpenGL programming guide][opengl-docs] and [the general docs on
//! framework crates][framework-crates] for more information.
