returns SMALLER, EQUAL, or LARGER according
to the x-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 x-coordinate and an
unbounded y-coordinate. Namely xc is vertical or has a
vertical asymptote. |
