I didn't have any plans to implement them, as I didn't know about them until I
looked them up on Wikipedia just now.  I'll consider implementing them, but I'm
not sure if it will happen soon.

This can already be done programmatically (see Figure.xlim() and Figure.ylim()),
but is not exposed yet via the default plot window GUI.  This will be exposed when
I decide how I want to expose it.  The most obvious answer is dragging, but the
question then becomes, how do you zoom back out?
