 Because the srcset and sizes attributes try to give the browser guidance
 on how CSS is going to handle images, we should be able to take into
 account image class attributes (and other attributes that could be used as
 CSS selectors) when using the {{{wp_calculate_image_srcset}}} and
 {{{wp_calculate_image_sizes}}} filters to set the appropriate srcset and
 sizes.

 It would also be helpful to be able to supply a context to functions like
 {{{wp_image_add_srcset_and_sizes}}} and
 {{{wp_make_content_images_responsive}}} so we can calculate different
 srcset and sizes attributes if a medium sized image is in the main content
 section vs. in an aside or other section.
