  25  *
  26  * Tests glCreateRenderbuffers to see if it behaves in the expected way, throwing
  27  * the correct errors, etc.
  28  *
  29  * From OpenGL 4.5, section 9.2.4 "Renderbuffer Objects", page 297:
  30  *
  31  * "void CreateRenderbuffers( sizei n, uint *renderbuffers );
  32  *
  33  * CreateRenderbuffers returns n previously unused renderbuffer names in
  34  * renderbuffers, each representing a new renderbuffer object which is a state
  35  * vector comprising all the state and with the initial values listed in table
  36  * 23.27. The state of each renderbuffer object is as if a name returned from
  37  * GenRenderbuffers had been bound to the RENDERBUFFER target, except that any
  38  * existing binding to RENDERBUFFER is not affected.
  39  *
  40  * Errors
  41  * An INVALID_VALUE error is generated if n is negative."
