What exactly do you mean with 'find'? The algorithm? Just take the
extrema of *all* points – for fonts this should be good enough,
because it is standard to have points at the curve extrema, thus
making the bounding box of the curve identical to the bounding box of
the points (both on and off points).

What exact rule are you referring to? My rule #3 was
(3) All points of A are lower than all points of B (or vice versa).
which doesn't seem to fit what you are talking about...

No, I'm not, but I ask you to have this in mind to find a solution
that can be easily extended to cover this situation, too (for example,
by using an extendable structure instead of a plain variable).
