Requires Cairo for node-canvas to work. See this document for installation.

Expects data from stdin in this JSON format:

{
  "meta": {
    "innerWidth": 1680,
    "innerHeight": 1050
  },
  "results": [
    [100, 100],
    [200, 200],
    [300, 300]
  ]
}

The program does not record the actual clicks. That data must be provided from elsewhere.
