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).

poking around at the numbers from disappearing_sliver2.

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.
