  30  *
  31  * "CreateTransformFeedbacks returns n previously unused transform feedback
  32  * object names in ids, each representing a new state vector, comprising the
  33  * state and with all the same initial values listed in table 23.48.
  34  * Errors
  35  *   An INVALID_VALUE error is generated if n is negative."
