This looks pretty much like a bug to me, since insets should place
Axes inside of other Axes. So things should not behave that way. But
my knowledge of this part of the API is pretty low, so someone else
with better knowledge should chime in? If at least Ben agrees on that
this is a bug, please file a bug report (it's somewhere in the sf
interface I believe).
Maybe, just to make a sanity check, make an even more simple script
with only two Axes. And afaik it's possible to attach files to bug
reports, so attach that script please. And: It really appears only if
shifting the bbox of an existent Axes? It works if a new Axes is
created with the offset from the beginning (I strongly believe it
does)? Your calls look ok to me.
I'm quite short of free time currently. Poke me in about a month if
you can efford this.
I'm not sure this helps (maybe in future it'll help :-)
