Hi Ethan. I just went to look at this, and it looks like you applied a
patch already. Thanks! I don't quite understand why this limit is there
at all. As long as the aspect ratio is > 0 and < infinity, I think we
should accept it. I hit this through normal usage, and I can imagine
hitting even the more extreme limit at some point later.

My use case is this:

- I'm plotting an image with annotations plotted on top (points, lines,
  etc).

- The initial plot indeed has a crazy aspect ratio, and isn't very
  useful. But I can clearly see the annotations, and I can then
  interactively zoom into the area with the annotations, producing a
  useful plot. The square aspect ratio is preserved by the zoom
  operation

Unless something predictable will break, maybe the limit should go away,
or become much larger?
