New Revision: 371

Rewriting BaseWindingForPlane() in polylib.c from the ground up.  The behavior is totally unchanged, and I verified this by running extensive tests.  The only difference is that the math precision is much much better now.  Performance should be better as well (but that is not tested).  This is a major milestone because it fixes two regression tests: disappearing_sliver2 and sparkly_seam.
Improvements to math precision is ongoing and more improvements can probably be made even after this patch.
I will update the README.txt files in the regression tests in a separate commit.  This commit only includes the actual fixed code.
