+DESCRIPTION OF PROBLEM:
+=======================
+
+The sample map contains a wedge brush.  The tip (the sharp edge) of the wedge
+is chopped off by 2 planes, leaving very narrow windings.  Each of these 2
+narrow windings is less than 0.1 units tall.  However, the wedge has height
+exactly equal to 1/8 unit at the point where it is chopped.  Therefore,
+the two narrow sides caused by the chops are expected to be degenerate and the
+top face of the wedge is expected to be unaffected.  This should leave a
+"hole" in the narrow part of the wedge.
+
+The hole isn't desirable but it's expected based on the logic in the code.
+Still, if there is a hole in the brush, I consider this regression test to
+be broken.

+DESCRIPTION OF PROBLEM:
+=======================
+
+The sample map contains a wedge brush.  The tip (the sharp edge) of the wedge
+is chopped off by the YZ plane (side 5, or the last side, of the brush).
+The height of the wedge where it is chopped is about 0.9.  This makes it
+barely smaller than DEGENERATE_EPSILON.  So the face resulting from the chop
+is probably degenerate, and that winding will be removed.  I'm now wondering
+what happens to the rest of the brush.  0.9 rounded to the nearest 1/8 unit
+is 1/8, so the top face of the brush should get a slight raise, making the
+"hole" even bigger.  The sides will have degenerate edges near the chop, so
+they will become triangles, creating open slivers in the sides.
+
+Although this behavior is a tad nasty, it is expected based on the way the
+code is written.  I want to make sure nothing really nasty happens.
+
+I consider this regression test to be broken if there is a "hole" in the brush,
+and I consider this test to be very broken if something more drastic happens.
