Putting comments from Wim from the other bug here:

Let's add a unique ID to the ROI and a parent ID:

struct ROI {
  GstMeta meta

  gint id;
  gint parent_id;
  GQuark roi_type;
  guint x, y, width, height;
}

this way we can:

 - add more meta later to describe the ROI bounding rectangle with ID in more
   detail
 - Make a big ROI with sub ROI having the parent_id of the big ROI to make
   subregions.

For arbitrary shapes, I would now advertise the ROI as a bounding rectangle
containing the object(s) of interest, for the shape of the actual object(s) we
would need another meta to describe them.
