What is Bounding Rectangles?

Bounding Rectangles is a macro that can create rectangles that bound selected objects. It can create a single bounding rectangle that bounds all selected objects, or it can create a bounding rectangle for each of multiple objects in a selection. The margin between the selected content and the bounding box can be set as an absolute distance, or as a percentage of the longer dimension of the selection.
