This function is a binary Curve operator: It takes two Curves as arguments
and returns a new Curve. The two Curves are combined by using the full first
Curve for the first portion of the result and by using the full second Curve
for the second portion of the result. The second Curve is translated such
that its point at fraction 0 is the same as the Point of the first Curve at
fraction 1.
