Which would introduce other precision problems :-(  Probably scaling EPSILON
up rather than the vectors down would help.  Any any case, the warning as
displayed is valid because they vectors are really not perpendicular.  So
they scene should be adjusted to use shorter vectors, which result in more
available precision.
