 330                        This method transforms a set of vertices using the CURRENT state
 331                        (lighting, projection, ...) but does not rasterize them.
 332                        They will only be put on screen later (with the POINT / LINE and
 333                        TRIANGLE op-codes). The problem is that you can have a triangle
 334                        with each point having been transformed using another state...
 335
 336                        In this implementation, I will emulate only ONE thing : each
 337                        vertex can have its own "WORLD" transformation (this is used in the
 338                        TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
 339                        execute buffer use the same state.
 340
 341                        If I find applications that change other states, I will try to do a
 342                        more 'fine-tuned' state emulation (but I may become quite tricky if
 343                        it changes a light position in the middle of a triangle).
 344
 345                        In this case, a 'direct' approach (i.e. without using OpenGL, but
 346                        writing our own 3D rasterizer) would be easier. */

 351                          matrix and store them in the vertex buffer
