Apple Color 1.5 - Manual (Page 368)

The Softness parameter applies a uniform feathering around the entire shape. This also
reveals a pair of inside and outside shapes that represent the inner and outer boundaries
of the feathering effect that’s applied to the shape.
2 If necessary, adjust the shape’s inner and outer shape to create the most appropriate
feathering outline around the perimeter of the shape.
This lets you create irregularly feathered outlines when you’re isolating a feature where
one edge should be hard, and another feathered.
To add control points to a previously existing shape
