Some have built this on their own but...
As a developer I would like to add some UIHint on an image property enabling focal point selection.
As an editor I want to be able to open a selected image and set a coordinate for this image on this content instance.
as a humble web developer I would like to to receive this focal point metadata in my code somehow and use it to generate proper markup.
Should we add "breathe in and breathe out while working on this" as well? :-)
And it might not be a UIHint needed but a separate type when thinking some more.
