They will oinly be put on screen later (with the POINT / LINE and TRIANGLE op-codes). The problem is that you can have a triangle with each point having been transformed using another state... In this implementation, I will emulate only ONE thing : each vertex can have its own "WORLD" transformation (this is used in the TWIST.EXE demo of the 5.2 SDK). I suppose that all vertices of the execute buffer use the same state. If I find applications that change other states, I will try to do a more 'fine-tuned' state emulation (but I may become quite tricky if it changes a light position in the middle of a triangle).
