Initial(and untested) version of a polyfill aiming to normalize IE10/IE11 pointer events.

var useOldStyleEvents = window.navigator.msPointerEnabled;

if (useOldStyleEvents) {
  // Add all appropriate events here, properly capitalized
  var events = ['PointerDown']

  for (i in events) {
    var ev = events[i];
    var oldEv = 'MS' + ev;
    var newEv = ev.toLowerCase();

    // Simulate the new-style event, but delegate it to the old-style one.
    $.event.special[newEv] = {
      bindType = oldEv,
      delegateType = oldEv
    }
  }
}

If I understand that correctly, the following line should read:

var useOldStyleEvents = window.navigator.msPointerEnabled && !window.navigator.pointerEnabled; 

As msPointerEnabled is true in IE11, too. We want those emulated events only in IE10.

Ah, I did not know that. Yes, you are correct.
