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