OfxParametricParameterSuiteV1::parametricParamSetNthControlPoint — Modifies an existing control point on a curve

force an animation keyframe to be set as well as a curve key, otherwise if false, a key will only be added if the curve is already animating.
This modifies an existing control point. Note that by changing key, the order of the control point may be modified (as you may move it before or after anther point). So be careful when iterating over a curves control points and you change a key.
