title: What is highstock.js - modules- canvas-tools?
body: <p>Just downloaded highstock 1.1.6.  The js directory includes a modules folder, which has a file named <code>canvas-tools.js</code>.  I have looked around both <a href="http://www.highcharts.com/products/highstock" rel="nofollow">highstocks.com</a> and <a href="http://www.highslide.com/" rel="nofollow">highslide.com</a> as well as searched their forums, but for the life of me I cannot find any documentation about what the module is or how to use it with highstock.js</p>
  
  <p>Might anyone on here be able to shed some light on this most mysterious of javascript libraries?</p>
  
  <p>Many thanks.</p>
