A more extensive description is rather well hidden in
section 5.5.1 of the Notation Reference.  It says:

"All graphical objects have a reference point, a horizontal extent and a 
vertical extent. The horizontal extent is a pair of numbers giving the 
displacements from the reference point of the left and right edges, 
displacements to the left being negative. The vertical extent is a pair of 
numbers giving the displacement from the reference point to the bottom and 
top edges, displacements down being negative."
