Create a Bezier shape or mask using the Pen tool

You can create a Bezier mask using the Pen tool on a selected layer in the Composition panel or Layer panel. You can
create a shape with a Bezier path using the Pen tool on a selected shape layer in the Composition panel. If you draw
with the Pen tool in the Composition panel with no layer selected, you create a shape on a new shape layer.

Creating a RotoBezier path is similar to creating a manual Bezier path. The primary difference is that direction lines
for vertices and curvature for path segments are automatically calculated.
