shape’s individual transform control remains visible.
Shape Bounding Boxes
Right-click a point, then choose Bounding Box Toggle from the shortcut menu to
display a box around that shape that can be transformed to move and scale the shape.
This works in addition to the shape’s transform control, which appears at the center of
the shape.

You can change the color of individual shapes, to change their effect on the alpha
channel they create. White shapes create solid areas, while black shapes create regions
of transparency.
To change the color of a shape:
1 Right-click a shape’s transform control, or any of its main control points.
2 Choose Black or White from the shortcut menu to change the shape to that color.
