#!/usr/bin/env python
# This extension is intended to alter text from the Machine Tool font
# family to be suitable for Eggbot plotting. It will
#
# -- Remove the fill option
# -- Enable the stroke option
# -- Set the stroke color to that of the fill or to black if there
# was no fill or the fill was white
# -- Set the stroke width to 1 pixel if no stroke width was set or
# if the stroke width was zero
# -- Fixup the character paths to remove closing line segments which
# existed in the character for purposes of making a closed polygon
# which could then be filled
#
# Note that some of the characters in the Machine Tool font family ARE NOT
# single stroke characters and thus will not work well with this extension.
# For example, the @, %, and ! characters.
#
# As of this writing, the Machine Tool family of fonts are available at
#
# http://www.featurecam.com/general/support/engrave_fonts.asp
