Plot both background and edge of colorbar bounding box to help  diagnose any colorbar bounding box or positioning issues.  For example, this plot currently demonstrates there are no such issues associated with the caps, but there continues to be the well-known issues where the numerical labeling of tick marks and the labels are currently ignored for bounding box size and position.
