Thanks! I've written some tests, and it seems like (at least) the last three
arguments are optional. Patch + testcase was added to the staging tree:

https://github.com/wine-compholio/wine-staging/blob/master/patches/d3dx9_36-IntersectTri/0001-d3dx9_36-Allow-NULL-pointer-for-optional-arguments-o.patch

Will try to submit it during the next weeks.
