31 * You are encouraged to submit all modifications to the Khronos group so that
32 * they can be included in future versions of this file.  Please submit changes
33 * by sending them to the public Khronos Bugzilla (http://khronos.org/bugzilla)
34 * by filing a bug against product "EGL" component "Registry".
