  Improvements with respect to that code:
- 1. Works on all browsers (WebKit, Firefox and IE >= 8)
+ 1. Works on all browsers (WebKit, Firefox and IE >= 9)
  2. Works for content in elements that are scrollable (i.e. have their own scrollbars)
  3. Much more comprehensive testing/error handling
  4. Properly encodes/decodes assertions
+ 5. Handles points in the padding of elements consistently
