Given a certain curveset, get_parametric_curveset_params() returns true
if the curveset contains parametric curves. Also, it returns the
parameters of the curveset (for each curve) and if the input should be
clamped or not.

This is not a generic function, it will specifically work for some well
behaved curveset. E.g. we return false if there are more than 3 curves
(one per color channel).
