It's a bit different from Direct3D runtime :-) I'm not really a lot into
DirectX, but my understanding is that the DirectX runtime is meant to be part
of the OS (and if the user doesn't have it from Windows Update already, you
can ship the redistributable), with a stable API and ABI (through COM).
D3DX is just a developers' convenience library that you could do without
(e.g., it has 4x4 matrix multiplication code), which is much more free to
change API and ABI, since it's something the developer is meant to use and
link (semi-)statically; a user is never supposed to worry about it.
