Adding new regression test, disappearing_sliver3. I discovered this while

poking around at the numbers from disappearing_sliver2.

+DESCRIPTION OF PROBLEM:
+=======================
+
+The example map, maps/disappearing_sliver3.map, contains an example of this
+bug.  The triangle sliver surface in the middle of the room is not rendered
+in the final BSP.
+
+To trigger the bug, compile the map; you don't need -vis or -light.  Only
+-bsp (the first q3map2 stage) is necessary to trigger the bug.  The only
+entities in the map are a light and a info_player_deathmatch, so the map will
+compile for any Q3 mod.
+
+
+SOLUTION TO PROBLEM:
+====================
+
+None yet.  Probably due to sloppy math code.
