vengrave takes an image file as a parameter and converts it into a series of toolpaths
in SVG format, in order to engrave the image.

It is implemented as a shell script which calls imagemagick (convert), ffmpeg, autotrace and ecce.

It also calls another shell script. "morph", which is a wrapper around some imagemagick commands.

The script is not complete yet; so far it just displays a simulation of the engraving as a video.

Conversion to gcode is relatively easy and will follow soon.
