294 This method transforms a set of vertices using the CURRENT state
295 (lighting, projection, ...) but does not rasterize them.
296 They will only be put on screen later (with the POINT / LINE and
297 TRIANGLE op-codes). The problem is that you can have a triangle
298 with each point having been transformed using another state...
299
300 In this implementation, I will emulate only ONE thing : each
301 vertex can have its own "WORLD" transformation (this is used in the
302 TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
303 execute buffer use the same state.
304
305 If I find applications that change other states, I will try to do a
306 more 'fine-tuned' state emulation (but I may become quite tricky if
307 it changes a light position in the middle of a triangle).
308
309 In this case, a 'direct' approach (i.e. without using OpenGL, but
310 writing our own 3D rasterizer) would be easier. */

317 the Identity matrix */
