MatrixDecomposed3D.add_weighted() is called with zero value for other_portion in case of iteration composite.

Browse source 
In the case where we accumulate transform:none onto decomposed matrix for
iteration composite whose iteration count is over 2, we pass zero
other_portion and self_portion which is over 1.0.  We should care about the
case.
