29. Rectangle spinning around the mouse pointer

In this episode we finally see how to rotate a rectangle around its own center. We add the fade-out effect to make the rectangle leave a nice blurry trail behind it, and changing just one line we make it spin around the mouse position.
Key ingredients for this episode are rectMode(), rotate() and translate().
