It really depends on the behavior you want for the tabs. If you need
center, right, and decimal align, it probably requires a complex solution.
Just jumping to the next multiple of N pixels could be done by some extended
interface on the context which inserts a spacing fragment or something. Or,
maybe you could insert the spacing from the TextFlow by checking how much
space is used in the LineBox.
