+ * Tests basic API support for glIsTransformFeedback().
+ *
+ * From the ARB_transform_feedback2 spec:
+ *
+ *     "The command
+ *
+ *         void GenTransformFeedbacks(sizei n, uint *ids)
+ *
+ *      returns <n> previously unused transform feedback object names in <ids>.
+ *      These names are marked as used, for the purposes of
+ *      GenTransformFeedbacks only, but they acquire transform feedback state
+ *      only when they are first bound.
+ *
+ *      [...]
+ *
+ *      A transform feedback object is created by binding a name
+ *      returned by GenTransformFeedbacks with the command
+ *
+ *         void BindTransformFeedback(enum target, uint id)"
