Add a method called animate that can be called to add some animation to your drawing. You can decide whether you want to include any parameters for this method that might affect the animation produced. The method does not return a value. Use the provided methods in the OUPolygon class. Remember that you can use Ctrl$+$Space to call up documentation and provide code completion in BlueJ. See the Software Guide Section $6\mathrm{.}2$ for more advice. You should show four animations, including at least one from each group below. Group A Group B Group C Rotation Move Change colour Reflection Change size Shear There is no required order for these animations. We want you to do something you find interesting and attractive. You are not required to reproduce the behaviours illustrated in the module website example: we just want to see something fun. If you find that your animations are happening too quickly for a user to see, use the provided OUPolygon.delay method. For example, OUPolygon.delay$(100)$ delays drawing of all objects on the canvas for $100$ milliseconds. Provide your animate method and any extra methods you wrote under this part, together with an explanation to your tutor of how to start your animation.
