LIke I said in my original post, the reduction in render times depended on
image content, and render mode (trace/scanline), but I still had an _Average_
improvement of 30%, which can't be sneezed at. 

Also, I have an 040, and remember the 040 has to deal with 68882 instructions
thru an exception handler in normal circumstances, these libraries eliminate
that overhead.

Can anyone else with an 040 comment?
