Image Crop/Scale breaks GIF animation

[grebaldi]

This is most likely an issue with Neos.Media rather than Sitegeist.Kaleidoscope, but I wanted put this issue here as a reminder before doing more in-depth research.

I found a promising hint for a general solution of the problem in this Stackoverflow answer:
https://stackoverflow.com/a/58427954

But again, I'm pretty sure, this needs to be implemented in Neos.Media.

The solution is based in Imagick directly. Neos Media works via Imagine https://github.com/avalanche123/Imagine which is an abstraction over various image libraries namely (imagick, gmagick, gd and vips). I expect this to be hard.

Wait i found this in the imagine docs https://imagine.readthedocs.io/en/stable/usage/layers.html#animated-gif-frame-manipulation. That could indeed enable cropping of animated gifs
