* EGL internally then this API can be used to retrieve the EGLDisplay
* handle that was setup internally. The result is undefined if Cogl
* is not using EGL.
*
* Note: The current window system backend can be checked using
* cogl_renderer_get_winsys_id().
*
* Return value: The internally setup EGLDisplay handle.
* Since: 1.8
* Stability: unstable
