Is it possible to composite GIFS over a base GIF?

Question about an existing feature

What are you trying to achieve?

Overlaying GIFS over a base GIF / merging multiple GIFs together.

When you searched for similar issues, what did you find that might be related?

I've searched, but did not find an equivalent issue

Please provide a minimal, standalone code sample, without other dependencies, that demonstrates this question

const compositeGif = someGif.gif
const finalImage = await sharp(compositeGif, { animated: true }).composite([
 {
          input: gifBuffer1,
          tile: true
        },
{
          input: gifBuffer2,
          tile: true
        }
], {}).gif()

It appears that sharp is currently only capable of overlaying static images (PNG, JPEG) over a base GIF. Is there something I'm missing here?

To use all frames of an animated image as the overlay, try something like:

          input: gifBuffer1,
+         animated: true,
          tile: true

This was missing from the docs, which I've just corrected in ac883c5

To stitch together animated images, so the frames of one follow another, please see future possible enhancement #1580

Thanks a ton, works like a charm!
