(
--- received arguments ---
PK_CURVE_t           curve,       --- a curve

--- returned arguments ---
PK_INTERVAL_t *const interval     --- parametric bounds of the curve
)


This function returns an interval indicating the parametric bounds of the
given curve.  If the curve is infinite, then a finite interval will be
returned which is sufficient to contain that part of the curve inside the
size box.
