I need to test this, but in general integration in the
digital world is the same as a sum.  You'd take each
segment, get the value for that segment given the
overall x extent (my function assumes it's 0..1),
then add them all together.  Somehow, I don't trust
this in this case -- will spend the rest of the day
probably worrying over this.
