glIsTransformFeedback returns GL_TRUE if id is currently the name of a transform feedback object. If id
       is zero, or if id is not the name of a transform feedback object, or if an error occurs,
       glIsTransformFeedback returns GL_FALSE. If id is a name returned by glGenTransformFeedbacks(), but that
       has not yet been bound through a call to glBindTransformFeedback(), then the name is not a transform
       feedback object and glIsTransformFeedback returns GL_FALSE.
