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.
