 362                        TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
 363                        execute buffer use the same state.
 364
 365                        If I find applications that change other states, I will try to do a
 366                        more 'fine-tuned' state emulation (but I may become quite tricky if
 367                        it changes a light position in the middle of a triangle).
 368
 369                        In this case, a 'direct' approach (i.e. without using OpenGL, but
 370                        writing our own 3D rasterizer) would be easier. */
