This bug concerns the poly object using POV-Ray Windows v3.1g.watcom
on a Pentium 200 Win98 platform. The error manifests itself as a black
pixelated line on the objects surface on the same plane and level as the
camera sits. The strum keyword does not appear to have any influence on
the problem.

   It should be noted however that the same object does render correctly
using POV-Ray v2.2 for DOS and in POV-Ray for Windows v3.01.watcom.win32
either with or without the sturm keyword. This suggests a strong possibility
that it is indeed a version related bug.

   This same problem can be seen with the Twin_Glob 6th order poly object
from the shapesq.inc file that is included with the distribution of POV-Ray.
