I would expect the top-left corner of the image would be in the top-left
corner of the content box. What would you suggest?

The basic case is a floated image where the shape is derived from that
image, where the shape and the image should be in perfect registration. I
think it would be fine to have a definition that fit that use case
exactly, and that also had a well-defined size and position for the case
you describe.
