   * types, renamed in EGL 1.3 so all types in the API start with "EGL".

   * Khronos STRONGLY RECOMMENDS that you use the default definitions
   * provided below, since these changes affect both binary and source
   * portability of applications using EGL running on different EGL
   * implementations.
