I'm at work, can test later on linux (debian) if required.

TL;DR:
clear all;
figure()
plot(1e-11:1e-11:1e-10)
print("correct.png", "-dpng")
ylim([0 1e-10])   % <-- NOTE: upper bound not correctly applied
print("wrong.png", "-dpng")  % <-- WRONG: upper y limit is reset -> image is
not what was desplayed before (regardless of wrong y limit)

## Summary
I've encountered a problem with setting small (presumably) y limits.
Reproducable on "qt" and "fltk". (gnuplot does work correctly, afaik)

1. When applying the y limit as in the above example, the correct limit is not
set. Also manually setting the limit via `set(get(gcf).currentaxes, 'ylim', [0
1e-10])` does not set/display the correct upper y limit.

2. This presumably leads to some weiredness when printing (or saving via the
graphical_toolkit "Save As" menu, fwiw):
The upper y limit is set the some incorrect value, distorting the plot
completely.
