Each field of the @ref GLFWvidmode structure corresponds to a function parameter

Window destruction always succeeds. Before the actual destruction, all

When a full screen window is destroyed, the original video mode of its monitor

For OpenGL ES, `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR` are
hard constraints to the extent that OpenGL ES 1.x cannot be returned if 2.0 or
