I didn't know about such division and I don't understand why it has been 
done. If I want to plot n rectangles what  function should I use? 
xrects? Even if n = 1?

It is a good idea and it is very simple to implement.

I am not sure that it is a good idea. This function use the axes scale 
and I am not sure that user want to have isometric axes. Besides, 
backward compatibility can be damaged. But it can be done in separate 
function. And in one year somebody will ask: "I am newbie and I didn't 
know about such division and I don't understand why it has been done." :-)

I don't understand what "returning the *vector of created handles*" is for?
