* "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

* 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)"
