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