/**
    Creates outlines of a single letter.
    There is a better version Outline2.foocad.

    Note, there is a similar script House/HouseNumbers.foocad,
    which has screw attachments.

    I created this for my front door.

    WARNING. This may fail for large widths and bezels. The *inside* of the shape
    Only works for a single character. Also fails for characters with holes. Ooops.
