Details:

These two figures should have the same size and position, regardless when they
are drawn:


f1 = figure();
pos1 = get(f1,"position")
pos1(1) = pos1(1) + 50;
pos1(2) = pos1(2) - 50;
pos1(3) = pos1(4) * 2
set(f1,"position",pos1) #before drawn
drawnow
get(f1,"position")

f2 = figure();
pos2 = get(f2,"position")
pos2(1) = pos2(1) + 50;
pos2(2) = pos2(2) - 50;
pos2(3) = pos2(4) * 2
drawnow
set(f2,"position",pos2) #after drawn
get(f2,"position")


but the position of the first figure is changed back by drawnow (and even not
exactly to the initial settings):


pos1 = 300   200   560   420
pos1 = 350   150   840   420
ans  = 300   200   560   418

pos2 = 300   200   560   420
pos2 = 350   150   840   420
ans  = 350   150   840   420


As far as I remember, Matlab always behaves like the second example. Maybe
somebody could check this...
