- Added D3DCREATE_FPU_PRESERVE to the IDirect3D9::CreateDevice() call.

Browse source 
Normally Direct3D sets the FPU to single precision. We don't want that,
  since it can mean going out of sync with machines that are using the
  standard precision. Additionally, the nodebuilder requires the extra
  precision that single precision lacks.

- Replaced the vector math routines with the ones I developed for the FP code.
