Michael,

To simplify things, the get_boundingbox and set_boudingbox methods for figure 
objects can be modified to set the origin in the UL corner.

Do you think this is an appropriate approach?

Or, might a 3rd boolean input be added get_boundingbox to allow the origin to 
be selected as LL or UL ?
