This is an example of how to use the mouse to select and drag multiple turtles.
We use two breeds of turtle:
You might think that the sides of the selection rectangle might better be represented by links. This would work, but it would have two drawbacks:
A third breed of turtles would be required in order to represent the corners of the box (because links must have turtles to connect).
It would work fine in a non-wrapping world, but in a wrapping world, a large selection rectangle would be drawn incorrectly because the sides would use the shortest possible path to connect the corners, and that path would sometimes wrap around the world boundaries.
