* This module relies heavily upon the Lazy Load plugin which was worked on by
* Mohammad Jangda (batmoo), the WordPress.com VIP team, the TechCrunch 2011
* redesign team, and Jake Goldman of 10up LLC.
*
* The JavaScript has been updated to rely on InterSection observer instead of
* jQuery Sonar. Many thanks to Dean Hume (deanhume) and his example:

* As an example, this is important if a theme wants to disable lazy images except
* on single posts, pages, or attachments by short-circuiting lazy images when
* is_singular() returns false.
