point of interest? What is this?

[yoshiki, 2013/04/25 16:05:19]

The value of point_of_interest is the last cursor position or the last touched
location. When changing the scale, the magnifier zooms in/out keeping this point
in the view port.

And here, this value is exposed only for unittest.

My point is there is no description of the method and the name doesn't convey in
any way what is returned.
