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.
