  29  * Tests basic API support for glIsTransformFeedback().
  30  *
  31  * From the ARB_transform_feedback2 spec:
  32  *
  33  *     "The command
  34  *
  35  *         void GenTransformFeedbacks(sizei n, uint *ids)
  36  *
  37  *      returns <n> previously unused transform feedback object names in <ids>.
  38  *      These names are marked as used, for the purposes of
  39  *      GenTransformFeedbacks only, but they acquire transform feedback state
  40  *      only when they are first bound.
  41  *
  42  *      [...]
  43  *
  44  *      A transform feedback object is created by binding a name
  45  *      returned by GenTransformFeedbacks with the command
  46  *
  47  *         void BindTransformFeedback(enum target, uint id)"
