fo (

returns SMALLER, EQUAL, or LARGER according
to the -ordering of a vertical line passing through the point
p and an unbounded end of the curve xc. The relevant end
is the minimal end, if ce is MIN_END and the maximal
end if ce is MAX_END.
Precondition: | the curve end has a bounded -coordinate and an
unbounded -coordinate. Namely xc is vertical or has a
vertical asymptote. |

Precondition: | the curve ends have a bounded -coordinate and an
