/*! @defgroup native Native access
*
* **By using the native API, you assert that you know what you're doing and
* how to fix problems caused by using it. If you don't, you shouldn't be
* using it.**
*
* Before the inclusion of @ref glfw3native.h, you must define exactly one
* window API macro and exactly one context API macro. Failure to do this
* will cause a compile-time error.
*
* The available window API macros are:
* * `GLFW_EXPOSE_NATIVE_WIN32`
* * `GLFW_EXPOSE_NATIVE_COCOA`
* * `GLFW_EXPOSE_NATIVE_X11`
*
* The available context API macros are:
* * `GLFW_EXPOSE_NATIVE_WGL`
* * `GLFW_EXPOSE_NATIVE_NSGL`
* * `GLFW_EXPOSE_NATIVE_GLX`
* * `GLFW_EXPOSE_NATIVE_EGL`
*
* These macros select which of the native access functions that are declared
* and which platform-specific headers to include. It is then up your (by
* definition platform-specific) code to handle which of these should be
* defined.
