Yes, this is I too deduced from the current documentation.

Yes, this is approximately the behaviour I observe.

I could do that, but some things are not clear to me.

1) I can enlarge the plot up to 1.2 without exceeding the window
   boundaries. 

2) Apparently, when you make subplots, you can still move them around
   through the whole window, which is good and useful, but also means
   that "outerposition" is somehow initialised: why can't one look at
   the initial values?

3) How does "aspectratio" interact with the imposed size?
