This node implements shortening each spline in the curve based on either a length from the start of each spline, or a factor of the total length of each spline, similar to the "Start & End Mapping" panel of curve properties. For Bezier curves, the first and last control points are adjusted to maintain the shape of the curve, but NURB splines are currently implicitly converted to poly splines. The node is implemented to avoid copying where possible, so it outputs a changed version of the input curve rather than a new one. Differential Revision: https://developer.blender.org/D11901
