But single precision could be optimized. 3D!Now & SSE use single precision
and PovRay can't use this, because of double precision. I am optimizing
PovRay for SSE2 ( uses double precision ), but not everybody have a Pentium
4 but I am looking for the possibility to make PovRay faster and it would be
easier to use 3D!Now & SSE to do that.
