# Vendored OpenGL headers and loader

## GLAD 2.0.8

`uhdk.h` with `UHDK_ENABLE_OPENGL` includes the generated `glad/gl.h`:
OpenGL 3.3 core, no
extensions, header-only output, explicit per-context tables (`--mx`), and no
platform loader. `src/glad.c` compiles its implementation into libuhdk. Applications
load a `GladGLContext` through their adapter for `uhdk_gl_context_get_proc`.

Generated unmodified with the pinned generator and its bundled Khronos snapshot:

```sh
python3 -m venv /tmp/uhdk-glad
/tmp/uhdk-glad/bin/pip install glad2==2.0.8
/tmp/uhdk-glad/bin/python -m glad --api gl:core=3.3 --extensions '' \
  --reproducible --out-path /tmp/uhdk-glad-output c --header-only --mx
```

Copy `/tmp/uhdk-glad-output/include/glad/gl.h` to `include/glad/gl.h`.
No generator or Python installation is required to build Uhdk.
