  /**
   * 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 *
   *
   * As of today, there are 4 DOM event types you can listen to:
   *
   *   'wheel'                -- Chrome(31+), FF(17+), IE(9+)
   *   'mousewheel'           -- Chrome, IE(6+), Opera, Safari
   *   'MozMousePixelScroll'  -- FF(3.5 only!) (2010-2013) -- don't bother!
   *   'DOMMouseScroll'       -- FF(0.9.7+) since 2003
   *
   * So what to do?  The is the best:
   *
   *   normalizeWheel.getEventType();
   *
   * In your event callback, use this code to get sane interpretation of the
   * deltas.  This code will return an object with properties:
   *
   *   spinX   -- normalized spin speed (use for zoom) - x plane
   *   spinY   -- " - y plane
   *   pixelX  -- normalized distance (to pixels) - x plane
   *   pixelY  -- " - 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:
   *
   *   - spin is trying to normalize how far the wheel was spun (or trackpad
   *     dragged).  This is super useful for zoom support where you want to
   *     throw away the chunky scroll steps on the PC and make those equal to
   *     the slow and smooth tiny steps on the Mac. Key data: This code tries to
   *     resolve a single slow step on a wheel to 1.
   *
   *   - pixel is normalizing the desired scroll delta in pixel units.  You'll
   *     get the crazy differences between browsers, but at least it'll be in
   *     pixels!
   *
   *   - positive value indicates scrolling DOWN/RIGHT, negative UP/LEFT.  This
   *     should translate to positive value zooming IN, negative zooming OUT.
   *     This matches the newer 'wheel' event.
   *
   * Why are there spinX, spinY (or pixels)?
   *
   *   - spinX is a 2-finger side drag on the trackpad, and a shift + wheel turn
   *     with a mouse.  It results in side-scrolling in the browser by default.
   *
   *   - spinY is what you expect -- it's the classic axis of a mouse wheel.
   *
   *   - I dropped spinZ/pixelZ.  It is supported by the DOM 3 'wheel' event and
   *     probably is by browsers in conjunction with fancy 3D controllers .. but
   *     you know.
   *
   * Implementation info:
   *
   * 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)
   *
   * On other/older browsers.. it's more complicated as there can be multiple and
   * also missing delta values.
   *
   * The 'wheel' event is more standard:
   *
   * http://www.w3.org/TR/DOM-Level-3-Events/#events-wheelevents
   *
   * The basics is that it includes a unit, deltaMode (pixels, lines, pages), and
   * deltaX, deltaY and deltaZ.  Some browsers provide other values to maintain
   * backward compatibility with older events.  Those other values help us
   * better normalize spin speed.  Example of what the browsers provide:
   *
   *                          | event.wheelDelta | event.detail
   *        ------------------+------------------+--------------
   *          Safari v5/OS X  |       -120       |       0
   *          Safari v5/Win7  |       -120       |       0
   *         Chrome v17/OS X  |       -120       |       0
   *         Chrome v17/Win7  |       -120       |       0
   *                IE9/Win7  |       -120       |   undefined
   *         Firefox v4/OS X  |     undefined    |       1
   *         Firefox v4/Win7  |     undefined    |       3
