Can this be used for a ripple effect that follows a finger dragging along the screen?

Example effect (ripple.js): https://youtu.be/AlKNJdMMCY8?t=12

Is that supported? If not, would it be a good fit for this package?

Hello,
this would work above an image.
As we don't have a stream of images that mirror the screen you'd have to do it yourself.

For better performance this would be better to move this to a shader.
As this repo is currently working on CPU, the bigger the area the worst are the performances.
