350                        (lighting, projection, ...) but does not rasterize them.
351                        They will only be put on screen later (with the POINT / LINE and
352                        TRIANGLE op-codes). The problem is that you can have a triangle
353                        with each point having been transformed using another state...
354
355                        In this implementation, I will emulate only ONE thing : each
356                        vertex can have its own "WORLD" transformation (this is used in the
357                        TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
358                        execute buffer use the same state.
359
360                        If I find applications that change other states, I will try to do a
361                        more 'fine-tuned' state emulation (but I may become quite tricky if
362                        it changes a light position in the middle of a triangle).
