Comment (by temmokan):

 @joemcgill Thanks for the patch code.

 Regarding CDN compatibility: is file structure expected to be

 <CDN URL part>/uploads/YYYY/MM/filename.ext

 or

 <CDN URL part>/YYYY/MM/filename.ext

 If the former, there will be less false srcset's added. If the second,
 more general, there will be more. Perhaps */uploads/* should be expected
 in CDN URLs?

 Note that if "pull" type of CDN is used, then uploads/*, or even wp-
 content/uploads/* will be present, most probably.
