Snippets are little embellishments you can use and re-use on your pattern.
They are typically used for things like logos or buttons.

Each snippet must have:

- An anchor point that determine where the snippet will be located
- The name of the snippet to insert

({ Point, points, Path, paths, options, part }) => {

  // Draws a w*h box, returns a Path object

Since our example image does not have any snippets in it, here's an example
of a `button` snippet:

<Example caption="An example of the button snippet">
```js
({ Point, Path, paths, Snippet, snippets, part }) => {

  snippets.demo = new Snippet('button', new Point(0,0))

  // Prevent clipping
  paths.diag = new Path()
    .move(new Point(-50,-4))
    .move(new Point(50,4))

  return part
}
```
</Example>
