1 DESCRIPTION OF PROBLEM:
2 =======================
4 In the disappearing_triangle regression test I outlined a potential problem
5 in the tjunction.c code, having to do with 2 points being too close together
6 on a winding, and that winding becoming invalid (drawsurf disappearing).
8 This example map is the same as disappearing_triangle.map, except that the
9 floor is raised by 1 unit. Therefore the floor intersects the sliver triangle.
10 The resulting chopped sliver has a very short edge that is "degenerate" and
11 causes that draw surf to go away due to problems in the tjunction.c code.
13 This is speculation at this point. I will provide more info after the bug has
