[pango: 3/4] Test more font sizes in the empty line height test

[Matthias Clasen <matthiasc src gnome org>]

commit 8c51a367c7bcaf8c84f04ddee7651aedbfd8909b
Author: Sebastian Keller <skeller gnome org>

    Test more font sizes in the empty line height test
    
    This would have caught the issue fixed in the previous commit, because
    the default font choice of "serif 12" happened to not be affected by it.
    Most other fonts or font sizes however were.
