The zero fDiscreteUnit in frame 0 is drawinglayer::primitive2d::DiscreteMetricDependentPrimitive2D::getDiscreteUnit() (i.e., drawinglayer::primitive2d::DiscreteMetricDependentPrimitive2D::mfDiscreteUnit, include/drawinglayer/primitive2d/primitivetools2d.hxx) as read in frame 1.  That mfDiscreteUnit is zet to zero in the DiscreteMetricDependentPrimitive2D constructor and only ever set to anything else in drawinglayer::primitive2d::DiscreteMetricDependentPrimitive2D::get2DDecomposition (drawinglayer/source/primitive2d/primitivetools2d.cxx).
