D3DCMPFUNC fix

[Paul Walker]

A tried to run Morrowind (it fails loading the outdoors).
I saw a message of unsupported D3DCMPFUNC. So I looked up MSDN and it
mentioned defaults, so I've added them. Not sure if they also need to be
in the d3d8/ directory too?
It didn't fix my problem, but it is probably still useful to have.
