I don't think that change should be there.

That and other places in that patch should be using HeapAlloc/HeapFree

I'm not sure about this, but I'm thinking it might be better to
generate a normalized vector there.

- The indentation in D3DRMVectorRotate is a bit of a mess
- Writing test cases doesn't hurt, and in this case should be pretty easy
