 369                        (lighting, projection, ...) but does not rasterize them.

 380                        more 'fine-tuned' state emulation (but I may become quite tricky if
 381                        it changes a light position in the middle of a triangle).
 382
 383                        In this case, a 'direct' approach (i.e. without using OpenGL, but
