Modified GDS read output to avoid generating error messages on

unrecognized layers when the "readonly" read option is set.
Added support to scale elements (from the "element" command,
such as the measurement text and arrows) when the grid scales,
which was missing.  Corrected the output of persistent elements
in a .mag file so that they are correctly scaled by the scale
reducer.
