Executing


graphics_toolkit qt
figure(1) ; clf ;
set(1, 'paperpositionmode', 'auto')
ax(1) = subplot(2,1,1) ;
plot(1:5)
xlabel XLABEL
title TITLE
legend('LEG', 'location', 'northeastoutside')
ax(2) = subplot(2,1,2) ;
plot(1:5)
xlabel XLABEL
title TITLE
legend('LEG', 'location', 'northeastoutside')
pos = get(ax, 'position') ;
disp([pos{1}(3:4) ; pos{2}(3:4)])


should result in two subplots of equal size, but it doesn't. The example does
not show a big effect, but I noticed this behaviour in a case where in fact
the bottom title and the top xlabel overlapped. 

I also noticed that stable and dev are slightly different:

stable:
   0.76992   0.33843
   0.76992   0.30274

dev:
   0.76992   0.33843
   0.76992   0.30036


Matlab and gnuplot work fine.
