Comment (by afercia):

 Refreshed patch, trying to simplify a bit and improve checking for
 visibility that fails in some edge cases, see for example:
 http://s.codepen.io/afercia/debug/YyRpzw
 * extends support to IE 8
 * no need for a `while` loop to recursively check the parent nodes
 * improves checking for elements hidden with CSS:
   * for visibility: `getComputedStyle()` / `currentStyle` already return
 the actual computed value, taking into account the ancestors visibility
 (doesn't work in IE 7-)
   * for display none: do the same thing jQuery does, checking for
 `offsetWidth` and `offsetHeight`

 Would greatly appreciate feedback and JavaScript review :)
