376 They will only be put on screen later (with the POINT / LINE and
377 TRIANGLE op-codes). The problem is that you can have a triangle
378 with each point having been transformed using another state...
379
380 In this implementation, I will emulate only ONE thing : each
381 vertex can have its own "WORLD" transformation (this is used in the
382 TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
383 execute buffer use the same state.
384
385 If I find applications that change other states, I will try to do a
386 more 'fine-tuned' state emulation (but I may become quite tricky if
387 it changes a light position in the middle of a triangle).
388
389 In this case, a 'direct' approach (i.e. without using OpenGL, but
390 writing our own 3D rasterizer) would be easier. */
