I have a script that produces many output images from many plot kinds (plotyy,
plot with subplots, etc). I am trying to align horizontally the plots by
setting the first and third element of the "position" axis property. I do
other customizations such as change of the fontsize, for this reason I need to
force "positionconstraint" to innerposition too. 

The plots look fine in the figures while print() produces an output image that
has a portion of the title text clipped when using multiline. The minimum code
snippet shows the difference in the result:


figure(1)
plot(1,1)
title(sprintf('first line\nsecond line'))
set(gca,'positionconstraint','innerposition')
print('bad.png')

figure(2)
plot(1,1)
title(sprintf('first line\nsecond line'))
set(gca,'positionconstraint','outerposition')  % not needed
print('good.png')


No annotation is added after the set() call so all the graphic elements should
have a defined position. If I invert the set() and title() calls the result is
the same, of course in that case the dimensions and position of the plots
would be slightly different.

With print() I expect to have the same result visible in the figure.
