Side note: I guess we could potentially get rid of the `#if D3DX_SDK_VERSION < 42` check and just always use `vkd3d_D3DCompile2VKD3D()`. If we start depending on vkd3d for some d3dx9_xx DLLs we might as well depend on it for all of them...
I did this to match native. If that's not important I'll get rid of it.
Ah, I see what you mean. No, let's keep it.
