Comment:

 We used this concept as a team hackathon - our original goal was to add
 `<picture>` style art direction support to the image editor, but the lack
 of hooks within the `wp_image_editor()` UI prevented any manipulation.

 Instead, we focused on making the UI more modular. attachment:30062.diff
 introduces several new functions - we used the add/remove
 register/unregister paradigm frequently implemented within WordPress to
 manage a list of editor groups for within the UI. The `wp_image_editor()`
 function has also been refactored to use the same mechanism to
 register/load/print existing core sections.

 We've added unit tests for the new functions, and also added escaping for
 variable output within existing code (i.e. moved the markup generation
 routines to discrete callbacks and ensured that passed args like
 `$post_id` are properly escaped).

 The project in all was a collaborative effort by:
