1) I corrected a cast that was added to remove a warning that was causing 
   the compiler to calculate a normalized normal differently, which was
   causing a few test suite failures. 

2) I modified the setting of the *_RELEASE flags that gets passed to cmake
   when running the regression suite on edge to add back the "-O3" that Mark 
   just removed. He changed it as a result of some bad information I gave him.
