maxReferencePositionOffsetFactor property
Max Amplitude factor of the curve. Affects how far the reference point at most be from mid point. Offset factor should be between 0 and 1. Default is Offset(1, 0.7), which means dx of Reference point should at most (1 * (width/2)) and dy of the Reference point should at most (0.7 * (width/2)) width/2 since the curve starts in center
