Extracted text: **15.15 (Geometry: add and remove points) Write a program that lets the user click on a pane to dynamically create and remove points (see Figure 15.30a). When the user left-clicks the mouse (primary button), a point is created and displayed at the mouse point. The user can remove a point by pointing to it and right- clicking the mouse (secondary button).
