Plus, it supports SSE2/SSE3 and AltiVec for ppc CPUs (I did the AltiVec port 
and I'm in the process of porting to Cell as well). Performance gain is more 
than 2-3x faster for SSE double and ~4x for single precision floats. Though, 
it's a C++ only library while Blender(renderer) is written in C (perhaps it 
would be a nice idea to port in C++ :)
