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".

62 * types, renamed in EGL 1.3 so all types in the API start with "EGL".
63 *
64 * Khronos STRONGLY RECOMMENDS that you use the default definitions

66 * portability of applications using EGL running on different EGL
67 * implementations.
