*MORPH CURRENT POINTS TO NEW POINTS USING LINEAR INTERPOLATION*
===============================================================

Morphs a curve by linearly interpolating between a set of "from" control points and a corresponding set of "to" control points, redistributing the curve's values accordingly. Use this worker when you need to warp or reshape a curve by mapping specific anchor points to new positions via linear interpolation.

     - Description
   * - Curve
     - curve
     - vector
     - —
     - 
     - Input curve (vector of X/Y pairs) to be morphed; this is the source curve whose points will be warped between the from/to control-point sets.
   * - From Points Csv
     - from_points_csv
     - text
     - —
     - 
     - CSV-formatted string listing the original (source) control-point coordinates used as the morph anchors; each row should be an X,Y pair defining where the curve currently passes.
   * - To Points Csv
     - to_points_csv
     - text
     - —
     - 
     - CSV-formatted string listing the target control-point coordinates that the corresponding from-points should be mapped to; must have the same number of rows as from_points_csv.
   * - Include Initial Points
     - includeinitialpoints
     - string
     - yes
     - 
     - Whether to prepend the original curve's first point to the morphed result ('yes' by default); set to 'no' to omit the initial anchor point from the output curve.
