New Revision: 379
Undoing revision 377 (reverting just those files modified by that
commit). I have disovered the fundamental problem to the math error problems,
and although this commit (r377) is "correct", it fails to address the
fundamental problem. Therefore, I'd rather leave the code in a state that
has the exact same behavior as before until I get a chance to address the
fundamental issue.

New Revision: 378
Updating notes on regression tests. They are "mostly sort of fixed". Won't
be fixed for good until I look at the last bit of code that has not been
examined yet, which is the plane intersection code. I want the errors to be
much less than they are now, even though the disappearing_sliver* tests are
now working.
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().

Following up on r371; found another optimization for math rounding errors
in BaseWindingForPlane(). This allows me to get rid of an extra call to
VectorSetLength() which contain floating point multiplications. Behavior
of BaseWindingForPlane() has been verified against base_winding regression
test (comparing output w/ logging patch).

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.

A regression test is included.
This is a bug in q3map2. Please read
regression_tests/q3map2/disappearing_sliver/README.txt for more info.
