Corrected an obscure error in GDS generation caused by an

uninitialized variable, with the result that writing GDS would
claim that it cannot scale down enough and that the output units
are either wrong or the output style must have "units angstroms".
Using angstrom units would solve the problem but did not treat
the root of the problem.
