From what I can tell (for DX9 at least), the app shouldn't be able to
use SetFunction(). I thought it was an internal wined3d function. Unless it's a DX8 call that I'm unaware of. I haven't seen any apps try to do that yet, but maybe I'm just not looking closely enough. :-) The apps tend to CreatePixelShader(), then later [often during the render loop], they SetPixelShader(). I haven't seen any that modify an existing shader yet.
