Comment 13 for bug 1388851

    it adds a new option 'read from file' to the input scaling options. This new option uses the variable $MEASUREMENT to determine whether the input scale is inches or mm.
    to use this new version you'll need to copy both files to the \Inkscape\share\extensions\ directory.
    this version is designed to run in recent trunk, with a Inkscape resolution of 96 dpi, not the previous 90 dpi. It will run in Inksc ape 0.48.5 if desired, but the resolution will still be 96 not 90, and you will also need to update the file inkex.py from the Inkscape repository, at:
