One thing to note when reading LibO's code (and also OOo's) is that, a
lot of code that are written by the Oracle folks avoid using unsigned
integers in favor of signed ones even though unsigned ones would make
more sense logically.  This is the case especially in newer code, such
as chart2 and oox.

I have no explanation for this other than to say that this practice was
probably largely inspired by Java, which doesn't have unsigned integer
types.
