svn r377 by Rambetter:

Continuing work on BaseWindingForPlane() in polylib.c.  In fact I'm pursuing
the approach that was committed in r375 (but was then backed out).  I can't
believe my eyes, but I seem to be getting 0.000000% error in some of my
regression tests.  The trick is to scale by a power of 2 and never do a
VectorNormalize().
