 This helper method lets you create a custom confetti shape using an [SVG Path string](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/d). Any valid path should work, though there are a few caveats:
 - All paths will be filed. If you were hoping to have a stroke path, that is not implemented.
 - Paths are limited to a single color, so keep that in mind.
-- All paths need a valid transform matrix. You can pass one in, or you can use this helper to calculate the matrix for you. Do note that calculating the matrix is a little expensive, so it is best to calculate it once for each path in development and cache that value, so that production confetti remain fast. The matrix is deterministic and will always be the same given the same path value.

 - For best forward compatibility, it is best to re-generate and re-cache the matrix if you update the `canvas-confetti` library.
-- Support for path-based confetti is limited to browsers which support [`Path2D`](https://developer.mozilla.org/en-US/docs/Web/API/Path2D), which should really be all major browser at this point. If `Path2D` is not supported, the library will all back to `square` confetti.

 This method will return a `Shape` -- it's really just a plain object with some properties, but shhh... we'll pretend it's a shape. Pass this `Shape` object into the `shapes` array directly.
