/**
 * @file istransformfeedback.c
 *
 * 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)"
