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

313 - I transform 'manually' all the vertices with the current WORLD

315 - during the rasterization phase, the WORLD matrix will be set to
316 the Identity matrix */
