 501            This method transforms a set of vertices using the CURRENT state
 502            (lighting, projection, ...) but does not rasterize them.
 503            They will oinly be put on screen later (with the POINT / LINE and
 504            TRIANGLE op-codes). The problem is that you can have a triangle
 505            with each point having been transformed using another state...
 506
 507            In this implementation, I will emulate only ONE thing : each
 508            vertex can have its own "WORLD" transformation (this is used in the
 509            TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the
 510            execute buffer use the same state.
 511
 512            If I find applications that change other states, I will try to do a
 513            more 'fine-tuned' state emulation (but I may become quite tricky if
 514            it changes a light position in the middle of a triangle).
 515
 516            In this case, a 'direct' approach (i.e. without using OpenGL, but
 517            writing our own 3D rasterizer) would be easier. */
