Actually, my experiments with MS Arial (not using Freetype, but with a
couple other renderers such as the Windows renderer and the OS/2 renderer)
show that number columns do align up, that the advance width of all the
digits is maintained identical. The "1"s have extra space left to the left
and the right to maintain the even advance width.
