Function MonoBehaviourGizmos.OnDrawGizmosSelected

void OnDrawGizmosSelected ()

An empty OnDrawGizmosSelected method.

Why an empty OnDrawGizmosSelected method? This is because only objects with an OnDrawGizmos/OnDrawGizmosSelected method will show up in Unity's menu for enabling/disabling the gizmos per object type (upper right corner of the scene view). So we need it here even though we don't use normal gizmos.

By using OnDrawGizmosSelected instead of OnDrawGizmos we minimize the overhead of Unity calling this empty method.
