What tool is specifically used to manipulate vector points on individual lines?

The Contour Editor tool is specifically designed for manipulating vector points along individual lines in Storyboard Pro. This tool allows users to make precise adjustments to the shape and curvature of vector paths. When working with vector graphics, having the ability to edit the individual control points is essential for achieving the desired aesthetics and ensuring that the artwork aligns with the creative vision.

Using the Contour Editor, you can move, add, or remove points on a path, offering a high level of control over the vector artwork. This tool is especially beneficial when fine-tuning drawings or animations, as it enables artists to create smooth lines and intricate shapes. The other tools serve different functions; for instance, the Select tool is primarily for selecting and manipulating entire objects rather than specific points, and the Layer Transform tool focuses on transforming layers as a whole rather than individual vector points. Consequently, the unique capabilities of the Contour Editor tool make it the correct choice for the task described in the question.
