Implemented a new command option "gds magscale" to reinterpret the
meaning of the MAG record in GDS files. Most available GDS documentation is decidedly vague about what MAG means. Most layout tools seem to interpret a MAG of 1 as corresponding to a text height of 1um. However, there are a few tools that interpret it as 1 centimicron, and there's no reason to assume that any given interpretation is correct. "gds magscale" allows the scale to be redefined.
