 365                        This method transforms a set of vertices using the CURRENT state
 366                        (lighting, projection, ...) but does not rasterize them.
 367                        They will only be put on screen later (with the POINT / LINE and
 368                        TRIANGLE op-codes). The problem is that you can have a triangle
 369                        with each point having been transformed using another state...
 370
 371                        In this implementation, I will emulate only ONE thing : each
 372                        vertex can have its own "WORLD" transformation (this is used in the
 373                        TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
 374                        execute buffer use the same state.
 375
 376                        If I find applications that change other states, I will try to do a
 377                        more 'fine-tuned' state emulation (but I may become quite tricky if
 378                        it changes a light position in the middle of a triangle).
 379
 380                        In this case, a 'direct' approach (i.e. without using OpenGL, but
 381                        writing our own 3D rasterizer) would be easier. */
