Perhaps the area displaying your canvas is bigger than the canvas
itself, so everything looks centered. E.g. displaying a 10x10 canvas in
a 200x200 window would look like:

------------
|          |
|          |
|    []    |
|          |
|          |
------------

(I'm no ascii-graphics artist)
So the origin looks more or less centered, even if it shouldn't.
That's a wild guess, of course.
