No, I don't need that for implementing d3d9 ATOC state. I just thought
that it is a step towards moving blend states to d3d11 style, which
looked natural if I was to implement wined3d_stateblock_set_blend_state().

Yes, that is something close to what I was trying to suggest a bit
earlier before considering broader plans of state redesign which you
shared. So I should probably go this way now? I suppose I can bypass the
proper creation and destruction of blend state object in state block
with wined3d_blend_state_create / decref, and just use it as a plain
structure.
