-h1. Element 'inview' Event Plugin
+h1. jQuery inview2
 
 Event that is fired as soon as an element appears in the user's viewport.
+Modified version of protonet's jquery.inview to use the more modern (and much faster) getBoundingClientRect() method.
+Props to him for his work on the original inview, but I found myself in need of a better-performing solution.

 The event will only fire when the element comes in to view of the viewport, and out of view. It won't keep firing if the user scrolls and the element remains in view.
 
 The variable after the event argument indicates the visible state in the viewport.
-The third variable visiblePartX detects which horizontal part of the element is visible to the user (possible values: left, right, both)
-The fourth variable visiblePartY detects which vertical part of the element is visible to the user (possible values: top, bottom, both)

-h2. More complex example
-
-This way we can attach inview to some DIV in our code to, for example, detect when it FULLY readed by user (user sees it's bottom and top) and only after 1 seconds of view, so after we call some out stats function or whatever

-bc.. $(someMyOneDiv).bind('inview', function(e, isInView, visiblePartX, visiblePartY) {

-  if (elem.data('inviewtimer')) {

-    elem.removeData('inviewtimer');

 h2. How it works
 
-An interval in the background checks the position of the elements against the viewport dimensions and the scroll position.
+An interval in the background checks the position of the bounding rectangle of elements against the viewport dimensions and the scroll position.
 
 However, I wanted to create a utility that would only check the elements that were registered under the 'inview' event, i.e. I didn't want to keep checking the element list if we unbind from the event.
