+DESCRIPTION OF PROBLEM:
+=======================
+
+The info_null in the map for the decal is not 100% below the center of the
+decal itself, because to be totally below it would have to lie on half-units.
+So, the info_null lies almost directly below the center of the decal.  In
+this particular case, all kinds of bad things happen to the decal.  For one,
+during compiling we get warnings like this:
+
+  Bad texture matrix! (B) (50.512253, -49.515625) != (50.484375, -49.515625)
+  Bad texture matrix! (C) (48.723190, -49.522587) != (48.695312, -49.515625)
+  Bad texture matrix! (B) (48.723186, -49.522587) != (48.695312, -49.515625)
+
+If you look at where the decal (it's just a blue translucent tile texture)
+meets the far wall, it's clearly not aligned correctly.  The tile on the decal
+and the tile on the wall should align perfectly, and it's quite a bit off.
