# 10 is not even enough to hold the spacing. The children should have
# a width of 0. Now we have to shrink the spacing. Its length is 7.
# There are two spacings: 7, 7 for a total of 14. We apply a homothecy
# to make it fit into 10. 7 * 10 / 14 = 5. 14*10/14=10. So we get 5 and
# 10 for coords out of the homothecy, and therefore 5 and 5 for the
# lengths of the spacing. We don't care about the lengths but we are
# interested in the coords since they give us the positions of our
# children. Just add a 0 in front of the list: 0, 5, 10.
