Octave sets the size of the gnuplot canvas when it sets the terminal.  
The result is that only the fontsize for eps output scales down.

I like the idea of generating a ps file and using it in place of eps  
(that solves the font size problem). I'll experiment with that to make  
sure there are not problems I haven't thought of.

Sorry, it is not my intent to argue. I've been in a rush for several  
weeks ... perhaps I should slow down and explain more.

The changes between 3.0.x and 3.2.x were to improve compatibility with  
Matlab.

Regarding what I see ...

(1) The ps output is not always properly centered, but I've not yet  
determine why.

(2) The eps output size is correct, but the fontsize is half what it  
should be.

(3) The axis labels often crop. This is due to changes which favor the  
axes position property of the outerposition property.

What I'd like to see ...

(1) the ps figure should be centered on the page (with default settings)

(2) The eps output should render the same fonts size as the ps output.

(3) Listeners should reconcile the position/outerposition/tightinset/ 
activepositionproperty properties, and would avoid cropping the axes  
labels when the activepositionproperty == "outerposition".

Until the listener in (3) are in place, I thought it easier to tweak  
the axes' position property to get the desired result, than the outer  
position property. In addition, the ability to explicitly set the  
axes' position is needed for the plotyy, subplot, and colorbar  
functions.
