Leap Motion generating programmatic Pointer Events

Demonstration of http://patrickhlauke.github.io/touch/leapmotion/tracker/ - a complete recode from last year's demo https://www.youtube.com/watch?v=9ilOFivWoXU - this time, using a fairly vanilla version of my tracker (with HUD) showing only pointer events, and a shim/polyfill that uses the proprietary Leap Motion API code to detect "pointables" (fingers / tools) and fire programmatic Pointer Events, which are then tracked the same way as "real" Pointer Events fired by touching the touchscreen or using the mouse.
