 297        The BIG problem with this method is nothing prevents D3D to do dirty tricks like
 298        processing two different sets of vertices with two different rendering parameters
 299        and then to display them using the same DrawPrimitive call.
 300
 301        It would be nice to check for such code here (but well, even this is not trivial
 302        to do).
 303
 304        This is exactly what the TWIST.EXE demo does but using the same kind of ugly stuff
 305        in the D3DExecuteBuffer code. I really wonder why Microsoft went back in time when
 306        implementing this mostly useless (IMHO) API.
