Lighting Simulation and Rendering System - SSE3 optimizations

 Radiance is intended to aid lighting designers and architects by
 predicting the light levels and appearance of a space prior to
 construction.
 .
 This package contains SSE3-optimized versions of the renderers. To be able
 to use them your processor needs to support the SSE3 instruction set.
 Using optimized binaries speeds up rendering by 5-15%.
