[Lewiscowles1986]

Right now this uses Imagemagick for proof of concept. Taking beyond simple shell script should be a goal.

• Way(s) to describe/markup from->to relationship of points
• Validations for each piece of data
  • Initial thoughts
    • co-ordinates from 0 to (canvas.width-1)
    • image dimensions (minimum of 2 pixels in each direction, maybe but that allows for no transformation)
    • validation that script is passed arguments.
• UI patterns for providing input.
