That makes sense, but perhaps state_alpha_test() in wined3d would be a more appropriate place.
Yes, sure. Anyway I was thinking of cleaning / extending the test and porting it to lower d3d versions before suggesting the fix upstream. Apart from checking lower d3d versions, it probably worth knowing which value d3d returns back in GetRenderState().
