* Mouse wheel (and 2-finger trackpad) support on the web sucks. It is
* complicated, thus this doc is long and (hopefully) detailed enough to answer
* your questions.
*
* If you need to react to the mouse wheel in a predictable way, this code is
* like your bestest friend. * hugs *
*
* In your event callback, use this code to get sane interpretation of the
* deltas. This code will return an object with properties:
*
* - deltaX -- normalized distance (to pixels) - x plane
* - deltaY -- " - y plane
*
* Wheel values are provided by the browser assuming you are using the wheel to
* scroll a web page by a number of lines or pixels (or pages). Values can vary
* significantly on different platforms and browsers, forgetting that you can
* scroll at different speeds. Some devices (like trackpads) emit more events
* at smaller increments with fine granularity, and some emit massive jumps with
* linear speed or acceleration.
*
* This code does its best to normalize the deltas for you:
*
* - delta* is normalizing the desired scroll delta in pixel units.
*
* - positive value indicates scrolling DOWN/RIGHT, negative UP/LEFT. This
* should translate to positive value zooming IN, negative zooming OUT.
* This matches the 'wheel' event.
*
* Implementation info:
*
* The basics of the standard 'wheel' event is that it includes a unit,
* deltaMode (pixels, lines, pages), and deltaX, deltaY and deltaZ.
* See: http://www.w3.org/TR/DOM-Level-3-Events/#events-wheelevents
*
* Examples of 'wheel' event if you scroll slowly (down) by one step with an
* average mouse:
*
* OS X + Chrome (mouse) - 4 pixel delta (wheelDelta -120)
* OS X + Safari (mouse) - N/A pixel delta (wheelDelta -12)
* OS X + Firefox (mouse) - 0.1 line delta (wheelDelta N/A)
* Win8 + Chrome (mouse) - 100 pixel delta (wheelDelta -120)
* Win8 + Firefox (mouse) - 3 line delta (wheelDelta -120)
*
* On the trackpad:
*
* OS X + Chrome (trackpad) - 2 pixel delta (wheelDelta -6)
* OS X + Firefox (trackpad) - 1 pixel delta (wheelDelta N/A)
