It must be said that the 1mm and 1cm will cause fractional pixel issue;
Chrome 17, Konqueror 4.8 (and presumably Safari 5.1.2) will have a 1px
taller black squares for 1mm and 1cm tests.

Test without verbose:

and again, 1px taller black squares for 1mm and 1cm tests in Chrome 17
and Konqueror 4.8 (and presumably Safari 5.1.2).
