When using the "individual origin" pivot mode, calculate the center based on the following: * If the stroke is a Bézier stroke, use the center of each handle as the pivot. * Otherwise, if the stroke is not a Bézier stroke, compute the mean position of the selected control points in the stroke and use this as the center. This center value is then used e.g. by the rotation or scale transform modes. Co-authored-by: Falk David <falk@blender.org> Pull Request: https://projects.blender.org/blender/blender/pulls/130723
