It seems to me like the box handler returns a set of pixels describing 
the box, and that the code added gets the coordinates for this.

I guess a simlpe approach is the use the coordinates  and construct a 
polygon geometry and then add this as a feature to a vector layer on the 
map, and then apply a style to make it look like the box.
